        + call delay_output_sp to handle BSD-style padding when tputs_sp is
          called, whether directly or internally, to ensure that the SCREEN
          pointer is passed correctly (reports by Henric Jungheim, Juraj

        + revert change to lib_addch.c in waddch_literal() from 20210130, since
          the followup fix in PutCharLR() actually corrects the problem while
          this change causes too-early filling/wrapping (report by Johannes

          writing to the lower-right corner, rather than decrementing the
          cursor column, in case it was a double-width character (cf: 20210130).

20210130
        + correct an off-by-one in comparison in waddch_literal() which caused
          scrolling when a double-cell character would not fit at the lower
          right corner of the screen (report by Benno Schulenberg).

        + amend man/curs_terminfo.3x, to note that <curses.h> is required
          for certain functions, e.g., those using chtype or attr_t for
          types, as well as mvcur (cf: 20201031).

          the middle of strings such as flash when the application uses
          low-level calls rather than curses (cf: 20161217).
        + modify configure check for c89/c99 aliases of clang to use its
          -std option instead, because some platforms, in particular macOS,

          buffer (report/testcases by Zhang Gan).
        + update length of strings in infocmp's usage function to restore a
          trailing null on the longest string (report/testcase by Zhang Gen).

20200704
        + modify version-check with Ada generics to use the same pattern as in
          the check for supported gnat versions (report by Pascal Pignard).

        + add --disable-pkg-ldflags to suppress EXTRA_LDFLAGS from the
          generated pkg-config and ncurses*-config files, to simplify
          configuring in the case where rpath is used but the packager wants
          to hide the feature (report by Michael Stapelberg).

            show distinct screen, window and terminal names anyway.
        + ensure that GCC_NORETURN is defined in term.h, because the prototype
          for exit_terminfo() uses it (report by Werner Fink).

          the --enable-warnings option is not used, to avoid unnecessary
          warnings about unrecognized inline options (report by Sven Joachim).

20190831

        + change a too-large terminal entry in tic from a fatal error to a
          warning (prompted by discussion with Gabriele Balducci).

20190112
        + fix typo in term(5), improve explanation of format (report by Otto
          Modinos).
        + add nsterm-direct -TD
        + use SGR 1006 mouse for konsole-base -TD
        + use SGR 1006 mouse for putty -TD
        + add ti703/ti707, ti703-w/ti707-w (Robert Clausecker)

20190105
        + add dummy "check" rule in top-level and test-Makefile to simply
          building test-packages for Arch.
        + modify configure script to avoid conflict with a non-POSIX feature
          that enables all parts of the system headers by default.  Some
          packagers have come to rely upon this behavior (FreeBSD #234049).
        + update config.guess, config.sub

20181229
        + improve man/curs_mouse.3x with regard to xterm
        + modify tracemunch to accept filename parameters in addition to use
          as a pipe/filter.
        + minor optimization to reduce calls to _nc_reserve_pairs (prompted by
          discussion with Bryan Christ).
        + add test/pair_content.c and test/color_content.c
        + modify infocmp to omit filtering of "OTxx" names which are used for
          obsolete capabilities, when the output is sorted by long-names.
          Doing this helps when making a table of the short/long capability
          names.

20181215
        + several fixes for gcc8 strict compiler warnings.
        + fix a typo in comments (Aaron Gyes).
        + add nsterm-build309 to replace nsterm-256color, assigning the latter
          as an alias of nsterm, to make mouse work with nsterm-256color -TD
        + base gnome-256color entry on "gnome", not "vte", for consistency -TD
        + updates for configure macros from work on tin and xterm:
          + CF_GNU_SOURCE, allow for Cygwin's newlib when checking for the
            _DEFAULT_SOURCE symbol.
          + CF_VA_COPY, add fallback check if neither va_copy/__va_copy is
            supported, to try copying the pointers for va_list, or as an array.
            Also add another fallback check, for __builtin_va_copy(), which
            could be used with AIX xlc in c89 mode.

20181208
        + modify wbkgd() and wbkgrnd() to improve compatibility with SVr4
          curses, changing the way the window rendition is updated when the
          background character is modified (report by Valery Ushakov).

20181201
        + add midnightbsd to CF_XOPEN_SOURCE macro (patch by Urs Jansen).
        + add "@" command to test/ncurses F-test, to allow rapid jump to
          different character pages.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20181125
        + build-fix (reports by Chih-Hsuan Yen, Sven Joachim).

20181124
        + check --with-fallbacks option to ensure there is a value, and add
          the fallback information to top-level Makefile summary.
        + add some traces in initialization to show whether a fallback entry is
          used.
        + build-fix for test/movewindow with ncurses-examples on Solaris.
        + add "-l" option to test/background, to dump screen contents in a form
          that lets different curses implementations be compared.
        + modify the initialization checks for mouse so that the xterm+sm+1006
          block will work with terminal descriptions not mentioning xterm
          (report by Tomas Janousek).

20181117
        + ignore the hex/b64 $TERMINFO in toe's listing.
        + correct a status-check in _nc_read_tic_entry() so that if reading
          a hex/b64 $TERMINFO, and the $TERM does not match, fall-through to
          the compiled-in search list.

20181110
        + several workarounds to ensure proper C compiler used in parts of
          Ada95 tree.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20181027
        + add OpenGL clients alacritty and kitty -TD
        + add Smulx for tmux, vte-2018 -Nicholas Marriott

20181020
        + ignore $TERMINFO as a default value in configure script if it came
          from the infocmp -Q option.
        + allow value for --with-versioned-syms to be a relative pathname
        + add a couple of broken-linker symbols to the list of versioned
          symbols to help with link-time optimization versus weak symbols.
        + apply shift/control/alt logic when decoding xterm's 1006 mode to
          wheel-mouse events (Redhat #1610681).

20181013
        + amend change from 20180818, which undid a fix for the $INSTALL value
          to make it an absolute path.

20181006
        + improve a configure check to work with newer optimizers (report by
          Denis Pronin, Gentoo #606142).
        + fix typo in tput.c (Sven Joachim, cf: 20180825).

20180929
        + fix typo in tvi955 -TD
        + corrected acsc for regent60 -TD
        + add alias n7900 -TD
        + corrected acsc for tvi950 -TD
        + remove bogus kf0 from tvi950 -TD
        + added function-key definitions to agree with Televideo 950 manual -TD
        + add bel to tvi950 -TD
        + add shifted function-keys to regent60 -TD
        + renumber regent40 function-keys to match manual -TD
        + add cd (clr_eos) to adds200 -TD

20180923
        + build-fix: remove a _tracef call which was used for debugging (report
          by Chris Clayton).

20180922
        + ignore interrupted system-call in test/ncurses's command-line, e.g.,
          if the terminal were resized.
        + add shift/control/alt logic for decoding xterm's 1006 mode (Redhat
          #1610681, cf: 20141011).
        + modify rpm test-packages to not use --disable-relink with Redhat,
          since Fedora 28's tools do not work with that feature.

20180908
        + document --with-pcre2 configure option in INSTALL.
        + improve workaround for special case in PutAttrChar() where a cell is
          marked as alternate-character set, to handle a case where the
          character in the cell does not correspond to any of the ASCII
          fallbacks (report by Leon Winter, cf: 20180505).
        + amend change to form library which attempted to avoid unnecessary
          update of cursor position in non-public fields, to simply disable
          output in this case (patch by Leon Winter, cf: 20180414).
        + improve check for LINE_MAX runtime limit, to accommodate broken
          implementations of sysconf().

20180901
        + improve manual page for wgetnstr, giving background for the length
          parameter.
        + define a limit for wgetnstr, wgetn_wstr when length is negative or
          "too large".
        + update configure script to autoconf 2.52.20180819 (Debian #887390).

20180825
        + add a section to tput manual page clarifying how it determines the
          terminal size (prompted by discussion with Grant Jenks).
        + add "--disable-relink" to rpm test-packages, for consistency with the
          deb test-packages.
        + split spec-file into ncurses6.spec and ncursest6.spec to work around
          toolset breakage in Fedora 28.
        + drop mention of "--disable-touching", which was not in the final
          20180818 updates.

20180818
        + build-fix for PDCurses with ncurses-examples.
        + improved CF_CC_ENV_FLAGS.
        + modify configure scripts to reduce relinking/ranlib during library
          install (Debian #903790):
          + use "install -p" when available, to avoid need for ranlib of
            static libraries.
          + modify scripts which use "--disable-relink" to add a 1-second
            sleep to work around tools which use whole-second timestamps, e.g.,
            in utime() rather than the actual file system resolution.

20180804
        + improve logic for clear with E3 extension, in case the terminal
          scrolls content onto its saved-lines before actually clearing
          the display, by clearing the saved-lines after clearing the
          display (report/patch by Nicholas Marriott).

20180728
        + improve documentation regarding feature-test macros in curses.h
        + improve documentation regarding the virtual and physical screens.
        + formatting fixes for manpages, regenerate man-html documentation.

20180721
        + build-fixes for gcc8.
        + corrected acsc for wy50 -TD
        + add wy50 and wy60 shifted function-keys as kF1 to kF16 -TD
        + remove ansi+rep mis-added to interix in 2018-02-23 -TD

20180714
        + add enum, regex examples to test/demo_forms
        + add configure check for pcre-posix library to help with MinGW port.

20180707
        + build-fixes for gcc8.
        + correct order of WINDOW._ttytype versus WINDOW._windowlist in
          report_offsets.
        + fix a case where tiparm could return null if the format-string was
          empty (Debian #902630).

20180630
        + add acsc string to vi200 (Nibby Nebbulous)
          add right/down-arrow to vi200's acsc -TD
        + add "x" to tput's getopt string so that "tput -x clear" works
          (Nicholas Marriott).
        + minor fixes prompted by anonymous report on stack overflow:
          + correct order of checks in _nc_get_locale(), for systems lacking
            locale support.
          + add "#error" in a few places to flag unsupported configurations

20180623
        + use _WIN32/_WIN64 in preference to __MINGW32__/__MINGW64__ symbols
          to simplify building with MSVC, since the former are defined in both
          compiler configurations (report by Ali Abdulkadir).
        + further improvements to configure-checks from work on dialog, i.e.,
          updated CF_ADD_INCDIR, CF_FIND_LINKAGE, CF_GCC_WARNINGS,
          CF_GNU_SOURCE, CF_LARGEFILE, CF_POSIX_C_SOURCE, CF_SIZECHANGE, and
          CF_TRY_XOPEN_SOURCE.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20180616
        + build-fix for ncurses-examples related to gcc8-fixes (cf: 20180526).
        + reduce use of _GNU_SOURCE for current glibc where _DEFAULT_SOURCE
          combines with _XOPEN_SOURCE (Debian #900987).
        + change target configure level for _XOPEN_SOURCE to 600 to address
          use of vsscanf and setenv.
        + improved configure-checks CF_SIZECHANGE and CF_STRUCT_TERMIOS from
          work on dialog.

20180609
        + modify generated ncurses*config and ncurses.pc, ncursesw.pc, etc.,
          to list helper libraries such as gpm for static linking (Debian
          #900839).
        + marked vwprintw and vwscanw as deprecated; recommend using vw_printw
          and vw_scanw, respectively.

20180602
        + add RPM test-package "ncursest-examples".
        + modified RPM test-package to work with Mageia6.

20180526
        + add note in curs_util.3x about unctrl.h
        + review/improve header files to ensure that those include necessary
          files except for the previously-documented cases (report by Isaac
          Pascual Monells).
        + improved test-package scripts, adapted from byacc 1.9 20180525.
        + fix some gcc8 warnings seen in Redhat package build, but
          work around bug in gcc8 compiler warnings in comp_parse.c

20180519
        + formatting fixes for manpages, regenerate man-html documentation.
        + trim spurious whitespace from tmux in 2018-02-24 changes;
          fix some inconsistencies in/between tmux- and iterm2-entries for SGR
          (report by C Anthony Risinger)
        + improve iterm2 using some xterm features which it has adapted -TD
        + add check in pair_content() to handle the case where caller asks
          for an uninitialized pair (Debian #898658).

20180512
        + remove trailing ';' from GCC_DEPRECATED definition.
        + repair a change from 20110730 which left an error-check/warning dead.
        + fix several minor Coverity warnings.

20180505
        + add deprecation warnings for internal functions called by older
          versions of tack.
        + fix a special case in PutAttrChar() where a cell is marked as
          alternate-character set, but the terminal does not actually support
          the given graphic character.  This would happen in an older terminal
          such as vt52, which lacks most line-drawing capability.
        + use configure --with-config-suffix option to work around filename
          conflict with Debian packages versus test-packages.
        + update tracemunch to work with perl 5.26.2, which changed the rules
          for escaping regular expressions.

20180428
        + document new form-extension O_EDGE_INSERT_STAY (report by Leon
          Winter).
        + correct error-returns listed in manual pages for a few form functions
          (report by Leon Winter).
        + add a check in form-library for null-pointer dereference:
                unfocus_current_field (form);
                form_driver (form, REQ_VALIDATION);
          (patch by Leon Winter).

20180414
        + modify form library to optionally delay cursor movement on a field
          edge/boundary (patch by Leon Winter).
        + modify form library to avoid unnecessary update of cursor position in
          non-public fields (patch by Leon Winter).
        + remove unused _nc_import_termtype2() function.
        + also add/improve null-pointer checks in other places
        + add a null-pointer check in _nc_parse_entry to handle an error when
          a use-name is invalid syntax (report by Chung-Yi Lin).

20180407
        + clarify in manual pages that vwprintw and vwscanw are obsolete,
          not part of X/Open Curses since 2007.
        + use "const" in some prototypes rather than NCURSES_CONST where X/Open
          Curses was updated to do this, e.g., wscanw, newterm, the terminfo
          interface.  Also use "const" for consistency in the termcap
          interface, which was withdrawn by X/Open Curses in Issue 5 (2007).
          As of Issue 7, X/Open Curses still lacks "const" for certain return
          values, e.g., keyname().

20180331
        + improve terminfo write/read by modifying the fourth item of the
          extended header to denote the number of valid strings in the extended
          string table (prompted by a comment in unibilium's sources).

20180324
        + amend Scaled256() macro in test/picsmap.c to cover the full range
          0..1000 (report by Roger Pau Monne).
        + add some checks in tracemunch for undefined variables.
        + trim some redundant capabilities from st-0.7 -TD
        + trim unnecessary setf/setb from interix -TD

20180317
        + fix a check in infotocap which may not have detected a problem when
          it should have.
        + add a check in tic for the case where setf/setb are given using
          different strings, but provide identical results to setaf/setab.
        + further improve fix for terminfo.5 (patch by Kir Kolyshkin).
        + reorder loop-limit checks in winsnstr() in case the string has no
          terminating null and only the number of characters is used (patch
          by Gyorgy Jeney).

20180303
        + modify TurnOn/TurnOff macros in lib_vidattr.c and lib_vid_attr.c to
          avoid expansion of "CUR" in trace.
        + improve a few lintian warnings in test-packages.
        + modify lib_setup to avoid calling pthread_self() without first
          verifying that the address is valid, i.e., for weak symbols
          (report/patch by Werner Fink).
        + modify generated terminfo.5 to not use "expand" and related width
          on the last column of tables, making layout on wide terminals look
          better (adapted from patch by Kir Kolyshkin).
        + add a category to report_offsets, e.g., "w" for wide-character, "t"
          for threads to make the report more readable.  Reorganized the
          structures reported to make the categories more apparent.
        + simplify some ifdef's for extended-colors.
        + add NCURSES_GLOBALS and NCURSES_PRESCREEN to report_offsets, to show
          how similar the different tinfo configurations are.

20180224
        + modify _nc_resolve_uses2() to detect incompatible types when merging
          a "use=" clause of extended capabilities.  The problem was seen in a
          defective terminfo integrated from simpleterm sources in 20171111,
          compounded by repair in 20180121.
        + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
        + fix remaining flash capabilities with trailing mandatory delays -TD
        + correct cut/paste in NEWS (report by Sven Joachim).

20180217
        + remove incorrect free() from 20170617 changes (report by David Macek).
        + correct type for "U8" in user_caps.5; it is a number not boolean.
        + add a null-pointer check in safe_sprintf.c (report by Steven Noonan).
        + improve fix for Debian #882620 by reusing limit2 variable (report by
          Julien Cristau, Sven Joachim).

20180210
        + modify misc/Makefile.in to install/uninstall explicit list in case
          the build-directory happens to have no ".pc" files when an uninstall
          is performed (report by Jeffrey Walton).
        + deprecate safe-sprintf, since the vsnprintf function, which does what
          was needed, was standardized long ago.
        + add several development/experimental options to development packages.
        + minor reordering of options in configure script to make the threaded
          and reentrant options distinct from the other extensions which are
          normally enabled.

20180203
        + minor fixes to test/*.h to make them idempotent.
        + add/use test/parse_rgb.h to show how the "RGB" capability works.
        + add a clarification in user_caps.5 regarding "RGB" capability.
        + add extended_slk_color{,_sp} symbols to the appropriate
          package/*.{map,sym} files (report by Sven Joachim, cf: 20170401).

20180129
        + update "VERSION" file, used in shared-library naming.

20180127 6.1 release for upload to ftp.gnu.org

20180127
        + updated release notes
        + amend a warning message from tic which should have flagged misuse
          of "XT" capability in "screen" terminal description.
        > terminfo changes:

        + mark konsole-420pc, konsole-vt100, konsole-xf3x obsolete reflecting
          konsole's removal in 2008 -TD
        + expanded the history section of konsole to explain its flawed
          imitation of xterm's keyboard -TD
        + use xterm+x11mouse in screen.* entries because screen does not yet
          support xterm's 1006 mode -TD
        + add nsterm-build400 for macOS 10.13 -TD
        + add ansi+idc1, use that in ansi+idc adding dch for consistency -TD
        + update vte to vte-2017 -TD
        + add ecma+strikeout to vte-2017 -TD
        + add iterm2-direct -TD
        + updated teraterm, added teraterm-256color -TD
        + add mlterm-direct -TD
        + add descriptions for ANSI building-blocks -TD

20180121 pre-release
        > terminfo changes:
        + add xterm+noalt, xterm+titlestack, xterm+alt1049, xterm+alt+title
          blocks from xterm #331 -TD
        + add xterm+direct, xterm+indirect, xterm-direct entries from xterm
          #331 -TD
        + modify xterm+256color and xterm+256setaf to use correct number of
          color pairs, for ncurses 6.1 -TD
        + add rs1 capability to xterm-256color -TD
        + modify xterm-r5, xterm-r6 and xterm-xf86-v32 to use xterm+kbs to
          match xterm #272, reflecting packager's changes -TD
        + remove "boolean" Se, Ss from st-0.7 -TD
        + add konsole-direct and st-direct -TD
        + remove unsupported "Tc" capability from st-0.7; use st-direct if
          direct-colors are wanted -TD
        + add vte-direct -TD
        + add XT, hpa, indn, and vpa to screen, and invis, E3 to tmux (patch by
          Pierre Carru)
        + use xterm+sm+1006 in xterm-new, vte-2014 -TD
        + use xterm+x11mouse in iterm, iterm2, mlterm3 because xterm's 1006
          mode does not work with those programs.  konsole is debatable -TD
        + add "termite" entry (report by Markus Pfeiffer) -TD
        > merge branch begun April 2, 2017 which provides these features:
        + support read/write new binary-format for terminfo which stores
          numeric capabilities as a signed 32-bit integer.  The test programs
          such as picsmap, ncurses were created or updated during 2017 to use
          this feature.
        + the new format is written by the wide-character configuration of
          tic when it finds a numeric capability larger than 32767.
        + other applications such as infocmp built with the wide-character
          ncurses library work as expected.
        + applications built with the "narrow" (8-bit) configuration will
          read the new format, but will limit those extended values to 32767.
        + in either wide/narrow configuration, the structure defined in
          term.h still uses signed 16-bit values.
        + because it is incompatible with the legacy (mid-1980s) binary format,
          a new magic value is provided for the "file" program.
        + the term.5 manual page is updated to describe this new format.
        + the limit on file-size for compiled terminfo is increased in the
          wide-character configuration to 32768.

20180120
        + build-fix in picsmap.c for stdint.h existence.
        + add --disable-stripping option to configure scripts.
        + modify ncurses-examples to install test-scripts in the data directory.
        + work around tool-breakage in Debian 9 and later by invoking
          gprconfig to specify the C compiler to be used by gnatmake,
          and conditionally suppressing Library_Options line for static
          libraries.
        + bump the compat level for test-packages to 7, i.e., Debian 5.

20180106
        + fixes for writing extended color pairs in putwin.
        + modify test/savescreen.c to add test patterns that exercise 88-,
          256-, etc., colors.
        + modify configure option --with-build-cc, adding clang, c89 and c99
          as possible default values.
        + modify ncurses-examples configure script to use pkg-config for the
          extra form/menu/panel libraries, to be more consistent with the
          handling of the curses/ncurses library.
        + modify test-packages for mingw to supply "pc" files.
        + modify gen-pkgconfig.in to list -lpthread as a private library when
          configured to access it via weak symbols.
        + simplify gen-pkgconfig.in, adding -ltinfo without the special linker
          checks because some versions of the linker simply hard-code the
          behavior.
        + update URLs for ncurses website to use https.
        + modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
          ncurses-examples are built with a system ncurses that lacks the
          standard "curses" symbolic link, as done by SuSE.  The symbol is
          needed to make a followup check for the pthread library work, and
          would be set properly using the options "--with-screen", etc.
        + generate misc/*.pc with "all" rule, as done for "sources" rule
          (report by Jeffrey Walton).

20171230
        + build-fix for ncurses-examples with Fedora27, adding check for
          reset_color_pairs() -- not yet in Fedora's package.
        + consistently add $CFLAGS to $MK_SHARED_LIB symbol in configure
          script when the latter happens to use the C compiler rather than
          directly using the loader (report by Jeffrey Walton).
        + set ABI for upcoming 6.1 release in "*.map" files.  While there are
          some remaining internals to apply, no ABI-related changes are
          anticipated.
        + add configure --with-config-suffix option to work around filename
          conflict with Redhat packages versus test-packages.

20171223
        + modify ncurses-examples to quiet const-warnings when building with
          PDCurses.
        + modify toe to not exit if unable to read a terminal description,
          e.g., if there is a permission problem.
        + minor fix for progs/toe.c, using _nc_free_termtype2.
        + assign 0 to pointer in _nc_tgetent_leak() after freeing it. Also
          avoid reusing pointer from previous successful call to tgetent
          if the latest call is unsuccessful (patch by Michael Schroeder,
          OpenSuSE #1070450).
        + minor fix for test/tracemunch, initialize $awaiting variable.

20171216
        + repair template in test/package/ncurses-examples.spec (cf: 20171111).
        + improve tic's warning about the number of parameters tparm might use
          for u1-u9 by making a special case for u6.
        + improve curs_attr.3x discussion of color pairs.

20171209
        + modify misc/ncurses-config.in to make output with --includedir
          consistent with --cflags, i.e., when --disable-overwrite option was
          configured the output should show the subdirectory where headers
          are.
        + modify MKlib_gen.sh to suppress macros when calling an "implemented"
          function in link_test.c
        + updated ftp-url used in test-packages, etc.
        + modify order of -pie/-shared options in configure script in case
          LDFLAGS uses "-pie", working around a defect or limitation in the GNU
          linker (prompted by patch by Yogesh Prasad, forwarded by Jay Shah).
        + add entry in man_db.renames for user_caps.5

20171125
        + modify MKlib_gen.sh to avoid tracing result from getstr/getnstr
          before initialized.
        + add "-a" aspect-ratio option to picsmap.
        + add configure check for default path of rgb.txt, used in picsmap.
        + modify _nc_write_entry() to truncate too-long filename (report by
          Hosein Askari, Debian #882620).
        + build-fix for ncurses-examples with NetBSD curses:
          + it lacks the use_env() function.
          + it lacks libpanel; a recent change used the wrong ifdef symbol.
        + add a macro for is_linetouched() and adjust the function's return
          value to make it possible for most applications to check for an
          error-return (report by Midolikawa H).
        + additional manpage cleanup.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20171118
        + add a note to curs_addch.3x on portability.
        + add a note to curs_pad.3x on the origin and portability of pads.
        + improve manpage description of getattrs (report by Midolikawa H).
        + improve manpage macros (prompted by discussion in Debian #880551.
        + reviewed test-programs using KEY_RESIZE, made fixes to test/worm.c
        + add a "-d" option to picsmap for default-colors.
        + modify old terminology entry and a few other terminal emulators to
          account for xon -TD
        + correct sgr string for tmux, which used screen's "standout" code
          rather than the standard code (patch by Roman Kagan)
        + correct sgr/sgr0 strings in a few other cases reported by tic, making
          those correspond to the non-sgr settings where they differ, but
          otherwise use ECMA-48 consistently:
          jaixterm, aixterm, att5420_2, att4424, att500, decansi, d410-7b,
          dm80, hpterm, emu-220, hp2, iTerm2.app, mterm-ansi, ncrvt100an,
          st-0.7, vi603, vwmterm -TD
        + build-fix for diagnostics warning in lib_mouse.c for pre-5.0 versions
          of gcc which did not recognize the diagnostic "push" pragma (patch by
          Vassili Courzakis).

20171111
        + add "op" to xterm+256setaf -TD
        + reviewed terminology 1.0.0 -TD
        + reviewed st 0.7 -TD
        + suppress debug-package for ncurses-examples rpm build.

20171104
        + check for interrupt in color-pair initialization of dots_curses.c,
          dots_xcurses.c
        + add z/Z zoom feature to test/ncurses.c C/c screens.
        + add '<' and '>' commands to test/ncurses.c S/s screens, to better
          test off-by-ones in the overlap/copywin functions.

20171028
        + improve man/curs_inwstr.3x, correct end-logic for lib_inwstr.c
          (report by Midolikawa H).
        + fix typo in a few places for "improvements" (patch by Sven Joachim).
        + clear the other half of a double-width character on which a line
          drawing character is drawn.
        + make test/ncurses.c "s" test easier to understand which subtests are
          available; add a "S" wide-character overlap test-screen.
        + modify test/ncurses.c C/c tests to allow for extended color pairs.
        + add endwin() call in error-returns from test/ncurses.c omitted in
          recent redesign of its menu (cf: 20170923).
        + improve install of hashed-db by removing the ".db" file as done for
          directory-tree terminal databases.
        + repair a few overlooked items in include/ncurses_defs from recent
          port/refactoring of test-programs (cf: 20170909).
        + add test/padview.c, to compare pads with direct updates in view.c

20171021
        + modify test/view.c to expand tabs using the ncurses library rather
          than in the test-program.
        + remove very old SIGWINCH example in test/view.c, just use KEY_RESIZE.
        + add -T, -e, -f -m options to "dots" test-programs.
        + fix a few typos in usage-messages for test-programs.

20171014
        + minor cleanup to test/view.c:
          + eliminate "-n" option by simply reading the whole file.
          + implement page up/down commands.
        + add check in tput for init/reset operands to ensure those use a
          terminal.
        + improve manual pages which discuss chtype, cchar_t types and the
          attribute values which can be stored in those types.
        + correct array-index when parsing "-T" command-line option in tabs
          program.
        + modify demo_new_pair.c to pass extended pairs to setcchar().
        + add test/dots_xcurses.c to illustrate a different approach used for
          extended colors which can be contrasted with dots_curses.c.
        + add a check in tic to note when a description uses non-mandatory
          delays without xon_xoff.  This is not an error, but some descriptions
          for a terminal emulator may use the combination incorrectly.

20171007
        + modify "-T" option of clear and tput to call use_tioctl() to obtain
          the operating system's notion of the screensize if possible.
        + review/repair some exit-codes for tput, making usage-message exit
          with 2 rather than 1, and a failure to open terminal 4+errno.
        + amend check in tput, tabs and clear to allow those to use the
          database-only features in cron if a -T option gives a suitable
          terminal name (report by Lauri Tirkkonen).
        + correct an ifdef in test/ncurses.c for systems with soft-keys but
          not slk_color().
        + regenerate man-html documentation.

20170930
        + fix a symbol conflict that made ncurses.c C/c menu not work with
          Solaris xpg4 curses.
        + add refresh() call to dots_mvcur.c, needed to use mvcur() with
          Solaris xpg4 curses after calling newterm().
        + minor fixes for configure script from work on ncurses-examples and
          tin.
        + improve animation in test/xmas.c by adding a time-delay in blinkit().
        + modify several test programs to reflect that ncurses honors existing
          signal handlers in initscr(), while other implementations do not.
        + modify bs.c to make it easier to quit.
        + change ncurses-examples to use attr_t vs chtype to follow X/Open
          documentation more closely since Solaris xpg4-curses uses different
          values for WA_xxx vs A_xxx that rely on attr_t being an unsigned
          short.  Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the
          two sets.

20170923
        + modify menu for test/ncurses.c to fit on 24-line screen.
        + build-fix for configure --with-caps=uwin
        + add options to test_arrays.c, for selecting termcap vs terminfo, etc.

20170916
        + minor fix to test/filter.c to avoid clearing the command in one case.
        + modify filter() to discard clr_eos if back_color_erase is set.

20170909
        + improve wide-character implementation of myADDNSTR() in frm_driver.c,
          which was inconsistent with the normal implementation.
        + save/restore cursor position in Undo_Justification(), matching
          behavior of Buffer_To_Window() (report by Leon Winter).
        + modify test/knight to provide the "slow" solution for small screens
          using "R", noting that Warnsdorf's method is easily done with "a".
        + modify several test-programs which call use_default_colors() to
          consistently do this only if "-d" option is given.
        + additional changes to test with non-standard variants of curses:
          + modify a loop limit in firework.c to work around absence of limit
            checks in some libraries.
          + fill the last row of a window with "?" in firstlast if waddch does
            not return ERR on the lower-right corner.
        + add checks in test/configure for some functions not in 4.3BSD curses.
        + fix a regression in test/configure (cf: 20170826).

20170902
        + amend change for endwin-state for better consistency with the older
          logic (report/patch by Jeb Rosen, cf: 20170722).
        + modify check in fmt_entry() to handle a cancelled reset string
          (Debian #873746).  Make similar fixes in other parts of dump_entry.c
          and tput.c

20170827
        + fix a bug in repeat_char logic (cf: 20170729, report by Chris Clayton).

20170826
        + fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
        + corrected a warning from tic about keys which are the same, to skip
          over missing/cancelled values.
        + add check in tic for unnecessary use of "2" to denote a shifted
          special key.
        + improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for
          cancelled string capabilities.
        + add check in _nc_parse_entry() for invalid entry name, setting the
          name to "invalid" to avoid problems storing entries.
        + add/improve checks in tic's parser to address invalid input
          + add a check in comp_scan.c to handle the special case where a
            nontext file ending with a NUL rather than newline is given to tic
            as input (Redhat #1484274).
          + allow for cancelled capabilities in _nc_save_str (Redhat #1484276).
          + add validity checks for "use=" target in _nc_parse_entry (Redhat
            #1484284).
          + check for invalid strings in postprocess_termcap (Redhat #1484285)
          + reset secondary pointers on EOF in next_char() (Redhat #1484287).
          + guard _nc_safe_strcpy() and _nc_safe_strcat() against calls using
            cancelled strings (Redhat #1484291).
        + correct typo in curs_memleaks.3x (Sven Joachim).
        + improve test/configure checks for some curses variants not based on
          X/Open Curses.
        + add options for test/configure to disable checks for form, menu and
          panel libraries.

20170819
        + update "iterm" entry -TD
        + add "iterm2" entry (report by Leonardo Brondani Schenkel) -TD
        + regenerate llib-* files.
        + regenerate HTML manpages.
        + improve picsmap test-program:
          + reduce memory used for tsearch
          + add report in log file showing cumulative color coverage.
        + add -x option to clear/tput to make the E3 extension optional
          (cf: 20130622).
        + add options -T and -V to clear command for compatibility with tput.
        + add usage message to clear command (Debian #371855).
        + improve usage messages for tset and tput.
        + minor fixes to "RGB" extension and reset_color_pairs().

20170812
        + improve description of -R option in infocmp manual page (report by
          Stephane Chazelas).
        + add reset_color_pairs() function.
        + add user_caps.5 manual page to document the terminfo extensions used
          by ncurses.
        + improve build scripts, using SIGQUIT vs SIGTRAP; add other configure
          script fixes from work on xterm, lynx and tack.
        + modify install-rule for ncurses-examples to put the data files in
          /usr/share/ncurses-examples
        + improve tracemunch, by changing address-parameters of add_wch(),
          color_content() and pair_content() to dummy parameters.
        + minor optimization to _nc_change_pair, to return quickly when the
          current screen is marked for clearing.
        + in-progress changes to improve performance of test/picsmap.c for
          loading image files.
        + modify allocation for SCREEN's color-pair table to start small, grow
          on demand up to the existing limit.
        + add "RGB" extension capability for direct-color support, use this to
          improve color_content().
        + improve picsmap test-program:
          + if no palette file is needed, attempt to load one based on $TERM,
            checking first in the current directory, then by adding ".dat"
            suffix, and finally in the data-directory, e.g.,
            /usr/share/ncurses-examples
          + add "-l" option for logging
          + add "-d" option for debugging
          + add "-s" option for stepping automatically through list of images,
            with time delay.
          + use tsearch to improve time for loading color table for images.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20170729
        + update interix entry using tack and SFU on Windows 7 Ultimate -TD
        + use ^? for kdch1 in interix (reported by Jonathan de Boyne Pollard)
        + add "rep" to xterm-new, available since 1997/01/26 -TD
        + move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
          Williams) -TD
        + add a check in newline_forces_scroll() in case a program moves the
          cursor outside scrolling margins (report by Robert King).
        + improve _nc_tparm_analyze, using that to extend the checks made by
          tic for reporting inconsistencies between the expected number of
          parameters for a capability and the actual.
        + amend handling of repeat_char capability in EmitRange (adapted from
          report/patch by Dick Wesseling):
          + translate the character to the alternate character set when the
            alternate character set is enabled.
          + do not use repeat_char for characters past 255.
        + document "_nc_free_tinfo" in manual page, because it could be used in
          tack for memory-leak checking.
        + add "--without-tack" configure option to refine "--with-progs"
          configure option.  Normally tack is no longer built in-tree, but
          a few packagers combine it during the build.  If term_entry.h is
          installed, there is no advantage to in-tree builds.
        + adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
          needed for tack 1.08 when built in-tree.  Rather than relying upon
          internal "_nc_" functions, tack now uses the boolean, number and
          string capability name-arrays provided by ncurses and SVr4 Unix
          curses.  It still uses term_entry.h for the definitions of the
          extended capability arrays.
        + add an overlooked null-pointer check in mvcur changes from 20170722

20170722
        + improve test-packages for ncurses-examples and AdaCurses for lintian
        + modify logic for endwin-state to be able to detect the case where
          the screen was never initialized, using that to trigger a flush of
          ncurses' buffer for mvcur, e.g., in test/dots_mvcur.c for the
          term-driver configuration.
        + add dependency upon ncurses_cfg.h to a few other internal header
          files to allow each to be compiled separately.
        + add dependency upon ncurses_cfg.h to tic's header-files; any program
          using tic-library will have to supply this file.  Legacy tack
          versions supply this file; ongoing tack development has dropped the
          dependency upon tic-library and new releases will not be affected.

20170715
        + modify command-line parameters for "convert" used in picsmap to work
          with ImageMagick 6.8 and newer.
        + fix build-problem with tack and ABI-5 (Debian #868328).
        + repair termcap-format from tic/infocmp broken in 20170701 fixes
          (Debian #868266).
        + reformat terminfo.src with 20170513 updates.
        + improve test-packages to address lintian warnings.

20170708
        + add a note to tic manual page about -W versus -f options.
        + correct a limit-check in fixes from 20170701 (report by Sven Joachim).

20170701
        + modify update_getenv() in db_iterator.c to ensure that environment
          variables which are not initially set will be checked later if an
          application happens to set them (patch by Guillaume Maudoux).
        + remove initialization-check for calling napms() in the term-driver
          configuration; none is needed.
        + add help-screen to test/test_getstr.c and test/test_get_wstr.c
        + improve compatibility between different configurations of new_prescr,
          fixing a case with threaded code and term-driver where c++/demo did
          not work (cf: 20160213).
        + the fixes for Redhat #1464685 obscured a problem subsequently
          reported in Redhat #1464687; the given test-case was no longer
          reproducible.  Testing without the fixes for the earlier reports
          showed a problem with buffer overflow in dump_entry.c, which is
          addressed by reducing the use of a fixed-size buffer.
        + add/improve checks in tic's parser to address invalid input
          (Redhat #1464684, #1464685, #1464686, #1464691).
          + alloc_entry.c, add a check for a null-pointer.
          + parse_entry.c, add several checks for valid pointers as well as
            one check to ensure that a single character on a line is not
            treated as the 2-character termcap short-name.
        + fix a memory leak in delscreen() (report by Bai Junq).
        + improve tracemunch, showing thread identifiers as names.
        + fix a use-after-free in NCursesMenu::~NCursesMenu()
        + further amend incorrect calls for memory-leaks from 20170617 changes
          (report by Allen Hewes).

20170624
        + modify c++/etip.h.in to accommodate deprecation of throw() and
          throws() in c++17 (prompted by patch by Romain Geissler).
        + remove some incorrect calls for memory-leaks from 20170617 changes
          (report by Allen Hewes).
        + add test-programs for termattrs and term_attrs.
        + modify _nc_outc_wrapper to use the standard output if the screen was
          not initialized, rather than returning an error.
        + improve checks for low-level terminfo functions when the terminal
          has not been initialized (Redhat #1345963).
        + modify make_hash to allow building with address-sanitizer,
          assuming that --disable-leaks is configured.
        + amend changes for number_format() in 20170506 to avoid undefined
          behavior when shifting (patch by Emanuele Giaquinta).

20170617
        + fill in some places where TERMTYPE2 vs TERMTYPE was not used
          (report by Allen Hewes).
        + use ExitTerminfo() internally in error-exits for ncurses' setupterm
          to help with leak checking.
        + use ExitProgram() in error-exit from initscr() to help with leak
          checking.
        + review test-programs, adding checks for cases where the terminal
          cannot be initialized.

20170610
        + add option "-xp" to picsmap.c, to use init_extended_pair().
        + make simple performance fixes for picsmap.c
        + improve aspect ratio of images read from "convert" in picsmap.c

20170603
        + add option to picsmap to use color-palette files, e.g., for mapping
          to xterm-256color.
        + move the data in SCREEN used for the alloc_pair() function to the
          end, to restore compatibility between ncurses/ncursesw libtinfo
          (report/patch by Miroslav Lichvar).
        + add build-time utility "report_offsets" to help show when the various
          configurations of tinfo library are compatible or not.

20170527
        + improved test/picsmap.c:
          + lookup named colors for xpm files in rgb.txt
          + accept blanks in color-keys for xpm files.
          + if neither xbm/xpm work, try "convert", which may be available.

20170520
        + modify test/picsmap.c to read xpm files.
        + modify package/debian/* to create documentation packages, so the
          related files can be checked with lintian.
        + fix some typos in manpages (report/patch by Sven Joachim).

20170513
        + add test/picsmap.c to fill in some testing issues not met by dots.
          The initial version reads X bitmap (".xbm") files.
        + repair logic which forces a repaint where a color-pair's content is
          changed (cf: 20170311).
        + improve tracemunch, showing screenXX pointers as names.

20170506
        + modify tic/infocmp display of numeric values to use hexadecimal when
          they are "close" to a power of two, making the result more readable.
        + improve discussion of portability in curs_mouse.3x
        + change line-length for generated html/manpages to 78 columns from 65.
        + improve discussion of line-drawing characters in curs_add_wch.3x
          (prompted by discussion with Lorinczy Zsigmond).
        + cleanup formatting of hackguide.html and ncurses-intro.html
        + add examples for WACS_D_PLUS and WACS_T_PLUS to test/ncurses.c

20170429
        + corrected a case where $with_gpm was set to "maybe" after CF_WITH_GPM,
          overlooked in 20160528 fixes (report by Alexandre Bury).
        + improve a couple of test-program's help-messages.
        + corrected loop in rain.c from 20170415 changes.
        + modify winnstr and winchnstr to return error if the output pointer is
          null, as well as adding a null pointer check of the window pointer
          for better compatibility with other implementations.
        + improve discussion of NetBSD curses in scr_dump.5
        + modify LIMIT_TYPED macro in new_pair.h to avoid changing sign of the
          value to be limited (reports by Darby Payne, Rob Boudreau).
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20170422
        + build-fix for termcap-configuration (report by Chi-Hsuan Yen).
        + improve terminfo manual page discussion of control- and graphics-
          characters.
        + remove tic warning about "^?" in string capabilities, which was
          marked as an extension (cf: 20000610, 20110820); however all Unix
          implementations support this and X/Open Curses does not address it.
          On the other hand, termcap never did support this feature.
        + correct missing comma-separator between string capabilities in
          icl6402 and m2-nam -TD
        + restore rmir/smir in ansi+idc to better match original ansiterm+idc,
          add alias ansiterm (report by Robert King).
        + amend an old check for ambiguous use of "ma" in terminfo versus
          a termcap use, if the capability is cancelled to treat it as number.
        + correct a case in _nc_captoinfo() which read "%%" and emitted "%".
        + modify sscanf calls in _nc_infotocap() for patterns "%{number}%+%c"
          and "%'char'%+%c" to check that the final character is really 'c',
          avoiding a case in icl6404 which cannot be converted to termcap.
        + in _nc_infotocap(), add a check to ensure that terminfo "^?" is not
          written to termcap, because the BSDs did not implement that.
        + in _nc_tic_expand() and _nc_infotocap(), improve string-length check
          when deciding whether to use "^X" or "\xxx" format for control
          characters, to make the output of tic/infocmp more predictable.
        + limit termcap "%d" width to 2 digits on input, and use "%2" in
          preference to "%02" on output.
        + correct terminfo/termcap conversion of "%02" and "%03" into "%2" and
          "%3"; the result repeated the last character.
        + add man/scr_dump.5 to document screen-dump format.

20170415
        + modify several test programs to use new popup_msgs, adapted from
          help-screen used in test/edit_field.c
        + drop two symbols obsoleted in 2004: _nc_check_termtype, and
          _nc_resolve_uses
        + fix some old copyright dates (cf: 20031025).
        + build-fixes for test/savescreen.c to work with AIX and HPUX.
        + minor fix to configure script, adding a backslash/continuation.
        + extend TERMINAL structure for ABI 6 to store numbers internally as
          integers rather than short, by adding new data for this purpose.
        + more fixes for minor memory-leaks in test-programs.

20170408
        + change logic in wins_nwstr() to avoid addressing data past the output
          of mbstowcs().
        + correct a call to setcchar() in Data_Entry_w() from 20131207 changes.
        + fix minor memory-leaks in test-programs.
        + further improve ifdef in term_entry.h for internal definitions not
          used by tack.

20170401
        + minor fixes for vt100+4bsd, e.g., delay in sgr for consistency -TD
        + add smso for env230, to match sgr -TD
        + remove p7/protect from sgr in fbterm -TD
        + drop setf/setb from fbterm; setaf/setab are enough -TD
        + make xterm-pcolor sgr consistent with other capabilities -TD
        + add rmxx/smxx ECMA-48 strikeout extension to tmux and xterm-basic
          (discussion with Nicholas Marriott)
        + add test-programs sp_tinfo and extended_color
        + modify no-leaks code for lib_cur_term.c to account for the tgetent()
          cache.
        + modify setupterm() to save original tty-modes so that erasechar()
          works as expected.  Also modify _nc_setupscreen() to avoid redundant
          calls to get original tty-modes.
        + modify set_curterm() to update ttytype[] data used by longname().
        + modify wattr_set() and wattr_get() to return ERR if win-parameter is
          null, as documented.
        + improve cast used for null-pointer checks in header macros, to
          reduce compiler warnings.
        + modify several functions, using the reserved "opts" parameter to pass
          color- and pair-values larger than 16-bits:
          + getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(),
            wattr_set(), wchgat(), wcolor_set().
          + Other functions call these with the corresponding altered behavior,
            including chgat(), mvchgat(), mvwchgat(), slk_color_on(),
            slk_color_off(), vid_attr().
        + add new functions for manipulating color- and pair-values larger
          than 16-bits.  These are extended_color_content(),
          extended_pair_content(), extended_slk_color(), init_extended_color(),
          init_extended_pair(), and the corresponding sp-funcs.

20170325
        + fix a memory leak in the window-list when creating multiple screens
          (reports by Andres Martinelli, Debian #783486).
        + reviewed calls from link_test.c, added a few more null-pointer
          checks.
        + add a null-pointer check in ungetmouse, in case mousemask was not
          called (report by "Kau").
        + updated curs_sp_funcs.3x for new functions.

20170318
        + change TERMINAL structure in term.h to make it opaque.  Some
          applications misuse its members, e.g., directly modifying it
          rather than using def_prog_mode().
        + modify utility headers such as tic.h to make it clearer which are
          externals that are used by tack.
        + improve curs_slk.3x in particular its discussion of portability.
        + fix cut/paste in legacy_encoding.3x
        + add prototype for find_pair() to new_pair.3x (report by Branden
          Robinson).
        + fix a couple of broken links in generated man-html documentation.
        + regenerate man-html documentation.

20170311
        + modify vt100 rs2 string to reset vt52 mode and scrolling regions
          (report/analysis by Robert King) -TD
        + add vt100+4bsd building block, use that for older terminals rather
          than "vt100" which is now mostly used as a building block for
          terminal emulators -TD
        + correct a few spelling errors in terminfo.src comments -TD
        + add fbterm -TD
        + fix a typo in ncurses.c test_attr legend (patch by Petr Vanek).
        + changed internal colorpair_t to a struct, eliminating an internal
          8-bit limit on colors
        + add ncurses/new_pair.h
        + add ncurses/base/new_pair.c with alloc_pair(), find_pair() and
          free_pair() functions
        + add test/demo_new_pair.c

20170304
        + improve terminfo manual description of terminfo syntax.
        + clarify the use of wint_t vs wchar_t in curs_get_wstr.3x
        + improve description of endwin() in manual.
        + modify setcchar() and getcchar() to treat negative color-pair as an
          error.
        + fix a typo in include/hashed_db.h (Andre Sa).

20170225
        + fixes for CF_CC_ENV_FLAGS (report by Ross Burton).

20170218
        + fix several formatting issues with manual pages.
        + correct read of terminfo entry in which all strings are absent or
          explicitly cancelled.  Before this fix, the result was that all were
          treated as only absent.
        + modify infocmp to suppress mixture of absent/cancelled capabilities
          that would only show as "NULL, NULL", unless the -q option is used,
          e.g., to show "-, @" or "@, -".

20170212
        + build-fixes for PGI compilers (report by Adam J. Stewart)
          + accept whitespace in sed expression for generating expanded.c
          + modify configure check that g++ compiler warnings are not used.
          + add configure check for -fPIC option needed for shared libraries.
        + let configure --disable-ext-funcs override the default for the
          --enable-sp-funcs option.
        + mark some structs in form/menu/panel libraries as potentially opaque
          without modifying API/ABI.
        + add configure option --enable-opaque-curses for ncurses library and
          similar options for the other libraries.

20170204
        + trim newlines, tabs and escaped newlines from terminfo "paths" passed
          to db-iterator.
        + ignore zero-length files in db-iterator; these are useful for
          instance to suppress "$HOME/.terminfo" when not wanted.
        + amended "b64:" encoder to work with the terminfo reader.
        + modify terminfo reader to accept "b64:" format using RFC-3548 in
          as well as RFC-4648 url/filename-safe format.
        + modify terminfo reader to accept "hex:" format as generated by
          "infocmp -0qQ1" (cf: 20150905).
        + adjust authors comment to reflect drop below 1% for SV.

20170128
        + minor comment-fixes to help automate links to bug-urls -TD
        + add dvtm, dvtm-256color -TD
        + add settings corresponding to xterm-keys option to tmux entry to
          reflect upcoming change to make that option "on" by default
          (patch by Nicholas Marriott).
        + uncancel Ms in tmux entry (Harry Gindi, Nicholas Marriott).
        + add dumb-emacs-ansi -TD

20170121
        + improve discussion of early history of tput program.
        + incorporate A_COLOR mask into COLOR_PAIR(), in case user application
          provides an out-of-range pair number (report by Elijah Stone).
        + clarify description in tput manual page regarding support for
          termcap names (prompted by FreeBSD #214709).
        + remove a restriction in tput's support for termcap names which
          omitted capabilities normally not shown in termcap translations
          (cf: 990123).
        + modify configure script for clang as used on FreeBSD, to work around
          clang's differences in exit codes vs gcc.

20170114
        + improve discussion of early history of tset/reset programs.
        + clarify in manual pages that the optional verbose option level is
          available only when ncurses is configured for tracing.
        + amend change from 20161231 to avoid writing traces to the standard
          error after initializing the trace feature using the environment
          variable.

20170107
        + amend changes for tput to reset tty modes to "sane" if the program
          is run as "reset", like tset.  Likewise, ensure that tset sends
          either reset- or init-strings.
        + improve manual page descriptions of tput init/reset and tset/reset,
          to make it easier to see how they are similar and different.
        + move a static result from key_name() to _nc_globals
        + modify _nc_get_screensize to allow for use_env() and use_tioctl()
          state to be per-screen when sp-funcs are configured, better matching
          the behavior when using the term-driver configuration.
        + improve cross-references in manual pages for often used functions
        + move SCREEN field for use_tioctl() data before the ncursesw fields,
          and limit that to the sp-funcs configuration to improve termlib
          compatibility (cf:  20120714).
        + correct order of initialization for traces in use_env() and
          use_tioctl() versus first trace calls.

20161231
        + fix errata for ncurses-howto (report by Damien Ruscoe).
        + fix a few places in configure/build scripts where DESTDIR and rpath
          were combined (report by Thomas Klausner).
        + merge current st description (report by Harry Gindi) -TD
        + modify flash capability for linux and wyse entries to put the delay
          between the reverse/normal escapes rather than after -TD
        + modify program tabs to pass the actual tty file descriptor to
          setupterm rather than the standard output, making padding work
          consistently.
        + explain in clear's manual page that it writes to stdout.
        + add special case for verbose debugging traces of command-line
          utilities which write to stderr (cf: 20161126).
        + remove a trace with literal escapes from skip_DECSCNM(), added in
          20161203.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20161224
        + correct parameters for copywin call in _nc_Synchronize_Attributes()
          (patch by Leon Winter).
        + improve color-handling section in terminfo manual page (prompted by
          patch by Mihail Konev).
        + modify programs clear, tput and tset to pass the actual tty file
          descriptor to setupterm rather than the standard output, making
          padding work.

20161217
        + add tput-colorcube demo script.
        + add -r and -s options to tput-initc demo, to match usage in xterm.
        + flush the standard output in _nc_flush for the case where SP is zero,
          e.g., when called via putp.  This fixes a scenario where "tput flash"
          did not work after changes in 20130112.

20161210
        + add configure script option --disable-wattr-macros for use in cases
          where one wants to use the same headers for ncurses5/ncurses6
          development, by suppressing the wattr* macros which differ due to
          the introduction of extended colors (prompted by comments in
          Debian #230990, Redhat #1270534).
        + add test/tput-initc to demonstrate tput used to initialize palette
          from a data file.
        + modify test/xterm*.dat to use the newer color4/color12 values.

20161203
        + improve discussion of field validation in form_driver.3x manual page.
        + update curs_trace.3x manual page.

20161126
        + modify linux-16color to not mask dim, standout or reverse with the
          ncv capability -TD
        + add 0.1sec mandatory delay to flash capabilities using the VT100
          reverse-video control -TD
        + omit selection of ISO-8859-1 for G0 in enacs capability from linux2.6
          entry, to avoid conflict with the user-defined mapping.  The reset
          feature will use ISO-8859-1 in any case (Mikulas Patocka).
        + improve check in tic for delays by also warning about beep/flash
          when a delay is not embedded, or if those use the VT100 reverse
          video escape without using a delay.
        + minor fix for syntax-check of delays from 20161119 changes.
        + modify trace() to avoid overwriting existing file (report by Maor
          Shwartz).

20161119
        + add check in tic for some syntax errors of delays, as well as use of
          proportional delays for non-line capabilities.
        + document history of the clear program and the E3 extension, prompted
          by various discussions including
          http://unix.stackexchange.com/questions/87469/clearing-the-old-scrollback-buffer

20161112
        + improve -W option in tic/infocmp:
          + correct order of size-adjustments in wrapped lines
          + if -f option splits line, do not further split it with -W
          + begin a new line when adding "use=" after a wrapped line

20161105
        + fix typo in man/terminfo.tail (Alain Williams).
        + correct program-name in adacurses6-config.1 manual page.

20161029
        + add new function "unfocus_current_field" (Leon Winter)

20161022
        + modify tset -w (and tput reset) to update the program's copy of the
          screensize if it was already set in the system, to improve tabstop
          setting which relies upon knowing the actual screensize.
        + add functionality of tset -w to tput, like the "-c" feature this is
          not optional in tput.
        + add "clear" as a possible link/alias to tput.
        + improve tput's check for being called as "init" or "reset" to allow
          for transformed names.
        + split-out the "clear" function from progs/clear.c, share with
          tput to get the same behavior, e.g., the E3 extension.

20161015
        + amend internal use of tputs to consistently use the number of lines
          affected, e.g., for insert/delete character operations.  While
          merging terminfo source early in 1995, several descriptions used the
          "*" proportional delay for these operations, prompting a change in
          doupdate.
        + regenerate llib-* files.
        + regenerate HTML manpages.
        + fix several formatting issues with manual pages.

20161008
        + adjust size in infocmp/tic to work with strlcpy.
        + fix configure script to record when strlcat is found on OpenBSD.
        + build-fix for "recent" OpenBSD vs baudrate.

20161001
        + add -W option to tic/infocmp to force long strings to wrap.  This is
          in addition to the -w option which attempts to fit capabilities into
          a given line-length.
        + add linux-m1 minitel entries (patch by Alexandre Montaron).
        + correct rs2 string for vt100-nam -TD

20160924
        + modify _nc_tic_expand to escape comma if it immediately follows a
          percent sign, to work with minitel change.
        + updated minitel and viewdata descriptions (Alexandre Montaron).

20160917
        + build-fix for gnat6, which unhelpfully attempts to compile C files.
        + fix typo in 20160910 changes (Debian #837892, patch by Sven Joachim).

20160910
        + trim dead code ifdef'd with HIDE_EINTR since 970830 (discussion with
          Leon Winter).
        + trim some obsolete/incorrect wording about EINTR from wgetch manual
          page (patch by Leon Winter).
        + really correct 20100515 change (patch by Rich Coe).
        + add "--enable-string-hacks" option to test/configure
        + completed string-hacks for "sprintf", etc., including test-programs.
        + make "--enable-string-hacks" work with Debian by checking for the
          "bsd" library and its associated "<bsd/string.h>" header.

20160903
        + correct 20100515 change for weak signals versus sigprocmask (report
          by Rich Coe).
        + modify misc/Makefile.in to work around OpenBSD "make" which unlike
          all other versions of "make" does not recognize continuation lines
          of comments.
        + amend the last change to CF_C_ENV_FLAGS to move only the
          preprocessor, optimization and warning flags to CPPFLAGS and CFLAGS,
          leaving the residue in CC.  That happens to work for gcc's various
          "model" options, but may require tuning for other compilers (report
          by Sven Joachim).

20160827
        + add "v" menu entry to test/ncurses.c to show baudrate and other
          values.
        + add "newer" baudrate symbols from Linux and FreeBSD to progs/tset.c,
          lib_baudrate.c
        + modify CF_XOPEN_SOURCE macro:
          + add "uclinux" to case for "linux" (patch by Yann E. Morin)
          + modify _GNU_SOURCE for cygwin headers, tested with cygwin 2.3, 2.5
            (patch by Corinna Vinschen, from changes to tin).
        + improve CF_CC_ENV_FLAGS macro to allow for compiler wrappers such
          as "ccache" (report by Enrico Scholz).
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20160820
        + update tput manual page to reflect changes to manipulate terminal
          modes by sharing functions with tset.
        + add the terminal-mode parts of "reset" (aka tset) to the "tput reset"
          command, making the two almost the same except for window-size.
        + adapt logic used in dialog "--keep-tite" option for test/filter.c as
          "-a" option.  When set, test/filter attempts to suppress the
          alternate screen.
        + correct a typo in interix entry -TD

20160813
        + add a dependency upon generated-sources in Ada95/src/Makefile.in to
          handle a case of "configure && make install".
        + trim trailing blanks from include/Caps*, to work around a problem
          in sed (Debian #818067).

20160806
        + improve CF_GNU_SOURCE configure macro to optionally define
          _DEFAULT_SOURCE work around a nuisance in recent glibc releases.
        + move the terminfo-specific parts of tput's "reset" function into
          the shared reset_cmd.c, making the two forms of reset use the same
          strings.
        + split-out the terminal initialization functions from tset as
          progs/reset_cmd.c, as part of changes to merge the reset-feature
          with tput.

20160730
        + change tset's initialization to allow it to get settings from the
          standard input as well as /dev/tty, to be more effective when
          output or error are redirected.
        + improve discussion of history and portability for tset/reset/tput
          manual pages.

20160723
        + improve error message from tset/reset when both stderr/stdout are
          redirected to a file or pipe.
        + improve organization of curs_attr.3x, curs_color.3x

20160709
        + work around Debian's antique/unmaintained version of mawk when
          building link_test.
        + improve test/list_keys.c, showing ncurses's convention of modifiers
          for special keys, based on xterm.

20160702
        + improve test/list_keys.c, using $TERM if no parameters are given.

20160625
        + build-fixes for ncurses "test_progs" rule.
        + amend change to CF_CC_ENV_FLAGS in 20160521 to make multilib build
          work (report by Sven Joachim).

20160618
        + build-fixes for ncurses-examples with NetBSD curses.
        + improve test/list_keys.c, fixing column-widths and sorting the list
          to make it more readable.

20160611
        + revise fix for Debian #805618 (report by Vlado Potisk, cf: 20151128).
        + modify test/ncurses.c a/A screens to make exiting on an escape
          character depend on the start of keypad and timeout modes, to allow
          better testing of function-keys.
        + modify rs1 for xterm-16color, xterm-88color and xterm-256color to
          reset palette using "oc" string as in linux -TD
        + use ANSI reply for u8 in xterm-new, to reflect vt220-style responses
          that could be returned -TD
        + added a few capabilities fixed in recent vte -TD

20160604
        + correct logic for -f option in test/demo_terminfo.c
        + add test/list_keys.c

20160528
        + further workaround for PIE/PIC breakage which causes gpm to not link.
        + fix most cppcheck warnings, mostly style, in ncurses library.

20160521
        + improved manual page description of tset/reset versus window-size.
        + fixes to work with a slightly broken compiler configuration which
          cannot compile "Hello World!" without adding compiler options
          (report by Ola x Nilsson):
          + pass appropriate compiler options to the CF_PROG_CC_C_O macro.
          + when separating compiler and options in CF_CC_ENV_FLAGS, ensure
            that all options are split-off into CFLAGS or CPPFLAGS
          + restore some -I options removed in 20140726 because they appeared
            to be redundant.  In fact, they are needed for a compiler that
            cannot combine -c and -o options.

20160514
        + regenerate HTML manpages.
        + improve manual pages for wgetch and wget_wch to point out that they
          might return values without names in curses.h (Debian #822426).
        + make linux3.0 entry the default linux entry (Debian #823658) -TD
        + modify linux2.6 entry to improve line-drawing so that the linux3.0
          entry can be used in non-UTF-8 mode -TD
        + document return value of use_extended_names (report by Mike Gran).

20160507
        + amend change to _nc_do_color to restore the early return for the
          special case used in _nc_screen_wrap (report by Dick Streefland,
          cf: 20151017).
        + modify test/ncurses.c:
          + check return-value of putwin
          + correct ifdef which made the 'g' test's legend not reflect changes
            to keypad- and scroll-modes.
        + correct return-value of extended putwin (report by Mike Gran).

20160423
        + modify test/ncurses.c 'd' edit-color menu to optionally read xterm
          color palette directly from terminal, as well as handling KEY_RESIZE
          and screen-repainting with control/L and control/R.
        + add 'oc' capability to xterm+256color, allowing palette reset for
          xterm -TD

20160416
        + add workaround in configure script for inept transition to PIE vs
          PIC builds documented in
                  https://fedoraproject.org/wiki/Changes/Harden_All_Packages
        + add "reset" to list of programs whose names might change in manpages
          due to program-transformation configure options.
        + drop long-obsolete "-n" option from tset.

20160409
        + modify test/blue.c to use Unicode values for card-glyphs when
          available, as well as improving the check for CP437 and CP850.

20160402
        + regenerate HTML manpages.
        + improve manual pages for utilities with respect to POSIX versus
          X/Open Curses.

20160326
        + regenerate HTML manpages.
        + improve test/demo_menus.c, allowing mouse-click on the menu-headers
          to switch the active menu.  This requires a new extension option
          O_MOUSE_MENU to tell the menu driver to put mouse events which do not
          apply to the active menu back into the queue so that the application
          can handle the event.

20160319
        + improve description of tgoto parameters (report by Steffen Nurpmeso).
        + amend workaround for Solaris line-drawing to restore a special case
          that maps Unicode line-drawing characters into the acsc string for
          non-Unicode locales (Debian #816888).

20160312
        + modified test/filter.c to illustrate an alternative to getnstr, that
          polls for input while updating a clock on the right margin as well
          as responding to window size-changes.

20160305
        + omit a redefinition of "inline" when traces are enabled, since this
          does not work with gcc 5.3.x MinGW cross-compiling (cf: 20150912).

20160220
        + modify test/configure script to check for pthread dependency of
          ncursest or ncursestw library when building ncurses examples, e.g.,
          in case weak symbols are used.
        + modify configure macro for shared-library rules to use -Wl,-rpath
          rather than -rpath to work around a bug in scons (FreeBSD #178732,
          cf: 20061021).
        + double-width multibyte characters were not counted properly in
          winsnstr and wins_nwstr (report/example by Eric Pruitt).
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20160213
        + amend fix for _nc_ripoffline from 20091031 to make test/ditto.c work
          in threaded configuration.
        + move _nc_tracebits, _tracedump and _tracemouse to curses.priv.h,
          since they are not part of the suggested ABI6.

20160206
        + define WIN32_LEAN_AND_MEAN for MinGW port, making builds faster.
        + modify test/ditto.c to allow $XTERM_PROG environment variable to
          override "xterm" as the name of the program to run in the threaded
          configuration.

20160130
        + improve formatting of man/curs_refresh.3x and man/tset.1 manpages
        + regenerate HTML manpages using newer man2html to eliminate some
          unwanted blank lines.

20160123
        + ifdef'd header-file definition of mouse_trafo() with NCURSES_NOMACROS
          (report by Corey Minyard).
        + fix some strict compiler-warnings in traces.

20160116
        + tidy up comments about hardcoded 256color palette (report by
          Leonardo Brondani Schenkel) -TD
        + add putty-noapp entry, and amend putty entry to use application mode
          for better consistency with xterm (report by Leonardo Brondani
          Schenkel) -TD
        + modify _nc_viscbuf2() and _tracecchar_t2() to trace wide-characters
          as a whole rather than their multibyte equivalents.
        + minor fix in wadd_wchnstr() to ensure that each cell has nonzero
          width.
        + move PUTC_INIT calls next to wcrtomb calls, to avoid carry-over of
          error status when processing Unicode values which are not mapped.

20160102
        + modify ncurses c/C color test-screens to take advantage of wide
          screens, reducing the number of lines used for 88- and 256-colors.
        + minor refinement to check versus ncv to ignore two parameters of
          SGR 38 and 48 when those come from color-capabilities.

20151226
        + add check in tic for use of bold, etc., video attributes in the
          color capabilities, accounting whether the feature is listed in ncv.
        + add check in tic for conflict between ritm, rmso, rmul versus sgr0.

20151219
        + add a paragraph to curs_getch.3x discussing key naming (discussion
          with James Crippen).
        + amend workaround for Solaris vs line-drawing to take the configure
          check into account.
        + add a configure check for wcwidth() versus the ncurses line-drawing
          characters, to use in special-casing systems such as Solaris.

20151212
        + improve CF_XOPEN_CURSES macro used in test/configure, to define as
          needed NCURSES_WIDECHAR for platforms where _XOPEN_SOURCE_EXTENDED
          does not work.  Also modified the test program to ensure that if
          building with ncurses, that the cchar_t type is checked, since that
          normally is since 20111030 ifdef'd depending on this test.
        + improve 20121222 workaround for broken acs, letting Solaris "work"
          in spite of its misconfigured wcwidth which marks all of the line
          drawing characters as double-width.

20151205
        + update form_cursor.3x, form_post.3x, menu_attributes.3x to list
          function names in NAME section (patch by Jason McIntyre).
        + minor fixes to manpage NAME/SYNOPSIS sections to consistently use
          rule that either all functions which are prototyped in SYNOPSIS are
          listed in the NAME section, or the manual-page name is the sole item
          listed in the NAME section.  The latter is used to reduce clutter,
          e.g., for the top-level library manual pages as well as for certain
          feature-pages such as SP-funcs and threading (prompted by patches by
          Jason McIntyre).

20151128
        + add option to preserve leading whitespace in form fields (patch by
          Leon Winter).
        + add missing assignment in lib_getch.c to make notimeout() work
          (Debian #805618).
        + add 't' toggle for notimeout() function in test/ncurses.c a/A screens
        + add viewdata terminal description (Alexandre Montaron).
        + fix a case in tic/infocmp for formatting capabilities where a
          backslash at the end of a string was mishandled.
        + fix some typos in curs_inopts.3x (Benno Schulenberg).

20151121
        + fix some inconsistencies in the pccon* entries -TD
        + add bold to pccon+sgr+acs and pccon-base (Tati Chevron).
        + add keys f12-f124 to pccon+keys (Tati Chevron).
        + add test/test_sgr.c program to exercise all combinations of sgr.

20151107
        + modify tset's assignment to TERM in its output to reflect the name by
          which the terminal description is found, rather than the primary
          name.  That was an unnecessary part from the initial conversion of
          tset from termcap to terminfo.  The termcap program in 4.3BSD did
          this to avoid using the short 2-character name (report by Rich
          Burridge).
        + minor fix to configure script to ensure that rules for resulting.map
          are only generated when needed (cf: 20151101).
        + modify configure script to handle the case where tic-library is
          renamed, but the --with-debug option is used by itself without
          normal or shared libraries (prompted by comment in Debian #803482).

20151101
        + amend change for pkg-config which allows build of pc-files when no
          valid pkg-config library directory was configured to suppress the
          actual install if it is not overridden to a valid directory at
          install time (cf: 20150822).
        + modify editing script which generates resulting.map to work with the
          clang configuration on recent FreeBSD, which gives an error on an
          empty "local" section.
        + fix a spurious "(Part)" message in test/ncurses.c b/B tests due
          to incorrect attribute-masking.

20151024
        + modify MKexpanded.sh to update the expansion of a temporary filename
          to "expanded.c", for use in trace statements.
        + modify layout of b/B tests in test/ncurses.c to allow for additional
          annotation on the right margin; some terminals with partial support
          did not display well.
        + fix typo in curs_attr.3x (patch by Sven Joachim).
        + fix typo in INSTALL (patch by Tomas Cech).
        + improve configure check for setting WILDCARD_SYMS variable; on ppc64
          the variable is in the Data section rather than Text (patch by Michel
          Normand, Novell #946048).
        + using configure option "--without-fallbacks" incorrectly caused
          FALLBACK_LIST to be set to "no" (patch by Tomas Cech).
        + updated minitel entries to fix kel problem with emacs, and add
          minitel1b-nb (Alexandre Montaron).
        + reviewed/updated nsterm entry Terminal.app in OSX -TD
        + replace some dead URLs in comments with equivalents from the
          Internet Archive -TD
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20151017
        + modify ncurses/Makefile.in to sort keys.list in POSIX locale
          (Debian #801864, patch by Esa Peuha).
        + remove an early-return from _nc_do_color, which can interfere with
          data needed by bkgd when ncurses is configured with extended colors
          (patch by Denis Tikhomirov).
        > fixes for OS/2 (patches by KO Myung-Hun)

        + support building with libtool on OS/2
        + use stdc++ on OS/2 kLIBC
        + clear cf_XOPEN_SOURCE on OS/2

20151010
        + add configure check for openpty to test/configure script, for ditto.
        + minor fixes to test/view.c in investigating Debian #790847.
        + update autoconf patch to 2.52.20150926, incorporates a fix for Cdk.
        + add workaround for breakage of POSIX makefiles by recent binutils
          change.
        + improve check for working poll() by using posix_openpt() as a
          fallback in case there is no valid terminal on the standard input
          (prompted by discussion on bug-ncurses mailing list, Debian #676461).

20150926
        + change makefile rule for removing resulting.map to distclean rather
          than clean.
        + add /lib/terminfo to terminfo-dirs in ".deb" test-package.
        + add note on portability of resizeterm and wresize to manual pages.

20150919
        + clarify in resizeterm.3x how KEY_RESIZE is pushed onto the input
          stream.
        + clarify in curs_getch.3x that the keypad mode affects ability to
          read KEY_MOUSE codes, but does not affect KEY_RESIZE.
        + add overlooked build-fix needed with Cygwin for separate Ada95
          configure script, cf: 20150606 (report by Nicolas Boulenguez)

20150912
        + fixes for configure/build using clang on OSX (prompted by report by
          William Gallafent).
          + do not redefine "inline" in ncurses_cfg.h; this was originally to
            solve a problem with gcc/g++, but is aggravated by clang's misuse
            of symbols to pretend it is gcc.
          + add braces to configure script to prevent unwanted add of
            "-lstdc++" to the CXXLIBS symbol.
          + improve/update test-program used for checking existence of stdc++
            library.
          + if $CXXLIBS is set, the linkage test uses that in addition to $LIBS

20150905
        + add note in curs_addch.3x about line-drawing when it depends upon
          UTF-8.
        + add tic -q option for consistency with infocmp, use it to suppress
          all comments from the "tic -I" output.
        + modify infocmp -q option to suppress the "Reconstructed from"
          header.
        + add infocmp/tic -Q option, which allows one to dump the compiled
          form of the terminal entry, in hexadecimal or base64.

20150822
        + sort options in usage message for infocmp, to make it simpler to
          see unused letters.
        + update usage message for tic, adding "-0" option.
        + documented differences in ESCDELAY versus AIX's implementation.
        + fix some compiler warnings from ports.
        + modify --with-pkg-config-libdir option to make it possible to install
          ".pc" files even if pkg-config is not found (adapted from patch by
          Joshua Root).

20150815
        + disallow "no" as a possible value for "--with-shlib-version" option,
          overlooked in cleanup-changes for 20000708 (report by Tommy Alex).
        + update release notes in INSTALL.
        + regenerate llib-* files to help with review for release notes.

20150810
        + workaround for Debian #65617, which was fixed in mawk's upstream
          releases in 2009 (report by Sven Joachim).  See
                https://invisible-island.net/mawk/CHANGES.html#t20090727

20150808 6.0 release for upload to ftp.gnu.org

20150808
        + build-fix for Ada95 on older platforms without stdint.h
        + build-fix for Solaris, whose /bin/sh and /usr/bin/sed are non-POSIX.
        + update release announcement, summarizing more than 800 changes across
          more than 200 snapshots.
        + minor fixes to manpages, etc., to simplify linking from announcement
          page.

20150725
        + updated llib-* files.
        + build-fixes for ncurses library "test_progs" rule.
        + use alternate workaround for gcc 5.x feature (adapted from patch by
          Mikhail Peselnik).
        + add status line to tmux via xterm+sl (patch by Nicholas Marriott).
        + fixes for st 0.5 from testing with tack -TD
        + review/improve several manual pages to break up wall-of-text:
          curs_add_wch.3x, curs_attr.3x, curs_bkgd.3x, curs_bkgrnd.3x,
          curs_getcchar.3x, curs_getch.3x, curs_kernel.3x, curs_mouse.3x,
          curs_outopts.3x, curs_overlay.3x, curs_pad.3x, curs_termattrs.3x
          curs_trace.3x, and curs_window.3x

20150719
        + correct an old logic error for %A and %O in tparm (report by "zreed").
        + improve documentation for signal handlers by adding section in the
          curs_initscr.3x page.
        + modify logic in make_keys.c to not assume anything about the size
          of strnames and strfnames variables, since those may be functions
          in the thread- or broken-linker configurations (problem found by
          Coverity).
        + modify test/configure script to check for pthreads configuration,
          e.g., ncursestw library.

20150711
        + modify scripts to build/use test-packages for the pthreads
          configuration of ncurses6.
        + add references to ttytype and termcap symbols in demo_terminfo.c and
          demo_termcap.c to ensure that when building ncursest.map, etc., that
          the corresponding names such as _nc_ttytype are added to the list of
          versioned symbols (report by Werner Fink)
        + fix regression from 20150704 (report/patch by Werner Fink).

20150704
        + fix a few problems reported by Coverity.
        + fix comparison against "/usr/include" in misc/gen-pkgconfig.in
          (report by Daiki Ueno, Debian #790548, cf:  20141213).

20150627
        + modify configure script to remove deprecated ABI 5 symbols when
          building ABI 6.
        + add symbols _nc_Default_Field, _nc_Default_Form, _nc_has_mouse to
          map-files, but marked as deprecated so that they can easily be
          suppressed from ABI 6 builds (Debian #788610).
        + comment-out "screen.xterm" entry, and inherit screen.xterm-256color
          from xterm-new (report by Richard Birkett) -TD
        + modify read_entry.c to set the error-return to -1 if no terminal
          databases were found, as documented for setupterm.
        + add test_setupterm.c to demonstrate normal/error returns from the
          setupterm and restartterm functions.
        + amend cleanup change from 20110813 which removed redundant definition
          of ret_error, etc., from tinfo_driver.c, to account for the fact that
          it should return a bool rather than int (report/analysis by Johannes
          Schindelin).

20150613
        + fix overflow warning for OSX with lib_baudrate.c (cf: 20010630).
        + modify script used to generate map/sym files to mark 5.9.20150530 as
          the last "5.9" version, and regenerated the files.  That makes the
          files not use ".current" for the post-5.9 symbols.  This also
          corrects the label for _nc_sigprocmask used in when weak symbols are
          configured for the ncursest/ncursestw libraries (prompted by
          discussion with Sven Joachim).
        + fix typo in NEWS (report by Sven Joachim).

20150606 pre-release
        + make ABI 6 the default by updates to dist.mk and VERSION, with the
          intention that the existing ABI 5 should build as before using the
          "--with-abi-version=5" option.
        + regenerate ada- and man-html documentation.
        + minor fixes to color- and util-manpages.
        + fix a regression in Ada95/gen/Makefile.in, to handle special case of
          Cygwin, which uses the broken-linker feature.
        + amend fix for CF_NCURSES_CONFIG used in test/configure to assume that
          ncurses package scripts work when present for cross-compiling, as the
          lessor of two evils (cf: 20150530).
        + add check in configure script to disallow conflicting options
          "--with-termlib" and "--enable-term-driver".
        + move defaults for "--disable-lp64" and "--with-versioned-syms" into
          CF_ABI_DEFAULTS macro.

20150530
        + change private type for Event_Mask in Ada95 binding to work when
          mmask_t is set to 32-bits.
        + remove spurious "%;" from st entry (report by Daniel Pitts) -TD
        + add vte-2014, update vte to use that -TD
        + modify tic and infocmp to "move" a diagnostic for tparm strings that
          have a syntax error to tic's "-c" option (report by Daniel Pitts).
        + fix two problems with configure script macros (Debian #786436,
          cf: 20150425, cf: 20100529).

20150523
        + add 'P' menu item to test/ncurses.c, to show pad in color.
        + improve discussion in curs_color.3x about color rendering (prompted
          by comment on Stack Overflow forum):
        + remove screen-bce.mlterm, since mlterm does not do "bce" -TD
        + add several screen.XXX entries to support the respective variations
          for 256 colors -TD
        + add putty+fnkeys* building-block entries -TD
        + add smkx/rmkx to capabilities analyzed with infocmp "-i" option.

20150516
        + amend change to ".pc" files to only use the extra loader flags which
          may have rpath options (report by Sven Joachim, cf: 20150502).
        + change versioning for dpkg's in test-packages for Ada95 and
          ncurses-examples for consistency with Debian, to work with package
          updates.
        + regenerate html manpages.
        + clarify handling of carriage return in waddch manual page; it was
          discussed only in the portability section (prompted by comment on
          Stack Overflow forum):

20150509
        + add test-packages for cross-compiling ncurses-examples using the
          MinGW test-packages.  These are only the Debian packages; RPM later.
        + cleanup format of debian/copyright files
        + add pc-files to the MinGW cross-compiling test-packages.
        + correct a couple of places in gen-pkgconfig.in to handle renaming of
          the tinfo library.

20150502
        + modify the configure script to allow different default values
          for ABI 5 versus ABI 6.
        + add wgetch-events to test-packages.
        + add a note on how to build ncurses-examples to test/README.
        + fix a memory leak in delscreen (report by Daniel Kahn Gillmor,
          Debian #783486) -TD
        + remove unnecessary ';' from E3 capabilities -TD
        + add tmux entry, derived from screen (patch by Nicholas Marriott).
        + split-out recent change to nsterm-bce as nsterm-build326, and add
          nsterm-build342 to reflect changes with successive releases of OSX
          (discussion with Leonardo B Schenkel)
        + add xon, ich1, il1 to ibm3161 (patch by Stephen Powell, Debian
          #783806)
        + add sample "magic" file, to document ext-putwin.
        + modify gen-pkgconfig.in to add explicit -ltinfo, etc., to the
          generated ".pc" file when ld option "--as-needed" is used, or when
          ncurses and tinfo are installed without using rpath (prompted by
          discussion with Sylvain Bertrand).
        + modify test-package for ncurses6 to omit rpath feature when installed
          in /usr.
        + add OSX's "*.dSYM" to clean-rules in makefiles.
        + make extra-suffix work for OSX configuration, e.g., for shared
          libraries.
        + modify Ada95/configure script to work with pkg-config
        + move test-package for ncurses6 to /usr, since filename-conflicts have
          been eliminated.
        + corrected build rules for Ada95/gen/generate; it does not depend on
          the ncurses library aside from headers.
        + reviewed man pages, fixed a few other spelling errors.
        + fix a typo in curs_util.3x (Sven Joachim).
        + use extra-suffix in some overlooked shared library dependencies
          found by 20150425 changes for test-packages.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20150425
        + expanded description of tgetstr's area pointer in manual page
          (report by Todd M Lewis).
        + in-progress changes to modify test-packages to use ncursesw6 rather
          than ncursesw, with updated configure scripts.
        + modify CF_NCURSES_CONFIG in Ada95- and test-configure scripts to
          check for ".pc" files via pkg-config, but add a linkage check since
          frequently pkg-config configurations are broken.
        + modify misc/gen-pkgconfig.in to include EXTRA_LDFLAGS, e.g., for the
          rpath option.
        + add 'dim' capability to screen entry (report by Leonardo B Schenkel)
        + add several key definitions to nsterm-bce to match preconfigured
          keys, e.g., with OSX 10.9 and 10.10 (report by Leonardo B Schenkel)
        + fix repeated "extra-suffix" in ncurses-config.in (cf: 20150418).
        + improve term_variables manual page, adding section on the terminfo
          long-name symbols which are defined in the term.h header.
        + fix bug in lib_tracebits.c introduced in const-fixes (cf: 20150404).

20150418
        + avoid a blank line in output from tabs program by ending it with
          a carriage return as done in FreeBSD (patch by James Clarke).
        + build-fix for the "--enable-ext-putwin" feature when not using
          wide characters (report by Werner Fink).
        + modify autoconf macros to use scripting improvement from xterm.
        + add -brtl option to compiler options on AIX 5-7, needed to link
          with the shared libraries.
        + add --with-extra-suffix option to help with installing nonconflicting
          ncurses6 packages, e.g., avoiding header- and library-conflicts.
          NOTE: as a side-effect, this renames
                  adacurses-config to adacurses5-config and
                  adacursesw-config to adacursesw5-config
        + modify debian/rules test package to suffix programs with "6".
        + clarify in curs_inopts.3x that window-specific settings do not
          inherit into new windows.

20150404
        + improve description of start_color() in the manual.
        + modify several files in ncurses- and progs-directories to allow
          const data used in internal tables to be put by the linker into the
          readonly text segment.

20150329
        + correct cut/paste error for "--enable-ext-putwin" that made it the
          same as "--enable-ext-colors" (report by Roumen Petrov)

20150328
        + add "-f" option to test/savescreen.c to help with testing/debugging
          the extended putwin/getwin.
        + add logic for writing/reading combining characters in the extended
          putwin/getwin.
        + add "--enable-ext-putwin" configure option to turn on the extended
          putwin/getwin.

20150321
        + in-progress changes to provide an extended version of putwin and
          getwin which will be capable of reading screen-dumps between the
          wide/normal ncurses configurations.  These are text files, except
          for a magic code at the beginning:
          0       string          \210\210        Screen-dump (ncurses)

20150307
        + document limitations of getwin in manual page (prompted by discussion
          with John S Urban).
        + extend test/savescreen.c to demonstrate that color pair values
          and graphic characters can be restored using getwin.

20150228
        + modify win_driver.c to eliminate the constructor, to make it more
          usable in an application which may/may not need the console window
          (report by Grady Martin).

20150221
        + capture define's related to -D_XOPEN_SOURCE from the configure check
          and add those to the *-config and *.pc files, to simplify use for
          the wide-character libraries.
        + modify ncurses.spec to accommodate Fedora21's location of pkg-config
          directory.
        + correct sense of "--disable-lib-suffixes" configure option (report
          by Nicolas Boos, cf: 20140426).

20150214
        + regenerate html manpages using improved man2html from work on xterm.
        + regenerated ".map" and ".sym" files using improved script, accounting
          for the "--enable-weak-symbols" configure option (report by Werner
          Fink).

20150131
        + regenerated ".map" and ".sym" files using improved script, showing
          the combinations of configure options used at each stage.

20150124
        + add configure check to determine if "local: _*;" can be used in the
          ".map" files to selectively omit symbols beginning with "_".  On at
          least recent FreeBSD, the wildcard applies to all "_" symbols.
        + remove obsolete/conflicting rule for ncurses.map from
          ncurses/Makefile.in (cf:  20130706).

20150117
        + improve description in INSTALL of the --with-versioned-syms option.
        + add combination of --with-hashed-db and --with-ticlib to
          configurations for ".map" files (report by Werner Fink).

20150110
        + add a step to generating ".map" files, to declare any remaining
          symbols beginning with "_" as local, at the last version node.
        + improve configure checks for pkg-config, addressing a variant found
          with FreeBSD ports.
        + modify win_driver.c to provide characters for special keys, like
          ansi.sys, when keypad mode is off, rather than returning nothing at
          all (discussion with Eli Zaretskii).
        + add "broken_linker" and "hashed-db" configure options to combinations
          use for generating the ".map" and ".sym" files.
        + avoid using "ld" directly when creating shared library, to simplify
          cross-compiles.  Also drop "-Bsharable" option from shared-library
          rules for FreeBSD and DragonFly (FreeBSD #196592).
        + fix a memory leak in form library Free_RegularExpression_Type()
          (report by Pavel Balaev).

20150103
        + modify_nc_flush() to retry if interrupted (patch by Stian Skjelstad).
        + change map files to make _nc_freeall a global, since it may be used
          via the Ada95 binding when checking for memory leaks.
        + improve sed script used in 20141220 to account for wide-, threaded-
          variations in ABI 6.

20141227
        + regenerate ".map" files, using step overlooked in 20141213 to use
          the same patch-dates across each file to match ncurses.map (report by
          Sven Joachim).

20141221
        + fix an incorrect variable assignment in 20141220 changes (report by
          Sven Joachim).

20141220
        + updated Ada95/configure with macro changes from 20141213
        + tie configure options --with-abi-version and --with-versioned-syms
          together, so that ABI 6 libraries have distinct symbol versions from
          the ABI 5 libraries.
        + replace obsolete/nonworking link to man2html with current one,
          regenerate html-manpages.

20141213
        + modify misc/gen-pkgconfig.in to add -I option for include-directory
          when using both --prefix and --disable-overwrite (report by Misty
          De Meo).
        + add configure option --with-pc-suffix to allow minor renaming of
          ".pc" files and the corresponding library.  Use this in the test
          package for ncurses6.
        + modify configure script so that if pkg-config is not installed, it
          is still possible to install ".pc" files (report by Misty De Meo).
        + updated ".sym" files, removing symbols which are marked as "local"
          in the corresponding ".map" files.
        + updated ".map" files to reflect move of comp_captab and comp_hash
          from tic-library to tinfo-library in 20090711 (report by Sven
          Joachim).

20141206
        + updated ".map" files so that each symbol that may be shared across
          the different library configurations has the same label.  Some
          review is needed to ensure these are really compatible.
        + modify MKlib_gen.sh to work around change in development version of
          gcc introduced here:
                  https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02185.html
                  https://gcc.gnu.org/ml/gcc-patches/2014-07/msg00236.html
          (reports by Marcus Shawcroft, Maohui Lei).
        + improved configure macro CF_SUBDIR_PATH, from lynx changes.

20141129
        + improved ".map" files by generating them with a script that builds
          ncurses with several related configurations and merges the results.
          A further refinement is planned, to make the tic- and tinfo-library
          symbols use the same versions across each of the four configurations
          which are represented (reports by Sven Joachim, Werner Fink).

20141115
        + improve description of limits for color values and color pairs in
          curs_color.3x (prompted by patch by Tim van der Molen).
        + add VERSION file, using first field in that to record the ABI version
          used for configure --with-libtool --disable-libtool-version
        + add configure options for applying the ".map" and ".sym" files to
          the ncurses, form, menu and panel libraries.
        + add ".map" and ".sym" files to show exported symbols, e.g., for
          symbol-versioning.

20141101
        + improve strict compiler-warnings by adding a cast in TRACE_RETURN
          and making a new TRACE_RETURN1 macro for cases where the cast does
          not apply.

20141025
        + in-progress changes to integrate the win32 console driver with the
          msys2 configuration.

20141018
        + reviewed terminology 0.6.1, add function key definitions.  None of
          the vt100-compatibility issues were improved -TD
        + improve infocmp conversion of extended capabilities to termcap by
          correcting the limit check against parametrized[], as well as filling
          in a check if the string happens to have parameters, e.g., "xm"
          in recent changes.
        + add check for zero/negative dimensions for resizeterm and resize_term
          (report by Mike Gran).

20141011
        + add experimental support for xterm's 1005 mouse mode, to use in a
          demonstration of its limitations.
        + add experimental support for "%u" format to terminfo.
        + modify test/ncurses.c to also show position reports in 'a' test.
        + minor formatting fixes to _nc_trace_mmask_t, make this function
          exported to help with debugging mouse changes.
        + improve behavior of wheel-mice for xterm protocol, noting that there
          are only button-presses for buttons "4" and "5", so there is no need
          to wait to combine events into double-clicks (report/analysis by
          Greg Field).
        + provide examples xterm-1005 and xterm-1006 terminfo entries -TD
        + implement decoder for xterm SGR 1006 mouse mode.

20140927
        + implement curs_set in win_driver.c
        + implement flash in win_driver.c
        + fix an infinite loop in win_driver.c if the command-window loses
          focus.
        + improve the non-buffered mode, i.e., NCURSES_CONSOLE2, of
          win_driver.c by temporarily changing the buffer-size to match the
          window-size to eliminate the scrollback.  Also enforce a minimum
          screen-size of 24x80 in the non-buffered mode.
        + modify generated misc/Makefile to suppress install.data from the
          dependencies if the --disable-db-install option is used, compensating
          for the top-level makefile changes used to add ncurses*-config in the
          20140920 changes (report by Steven Honeyman).

20140920
        + add ncurses*-config to bin-directory of sample package-scripts.
        + add check to ensure that getopt is available; this is a problem in
          some older cross-compiler environments.
        + expanded on the description of --disable-overwrite in INSTALL
          (prompted by reports by Joakim Tjernlund, Thomas Klausner).
          See Gentoo #522586 and NetBSD #49200 for examples.
          which relates to the clarified guidelines.
        + remove special logic from CF_INCLUDE_DIRS which adds the directory
          for the --includedir from the build (report by Joakim Tjernlund).
        + add case for Unixware to CF_XOPEN_SOURCE, from lynx changes.
        + update config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20140913
        + add a configure check to ignore some of the plethora of non-working
          C++ cross-compilers.
        + build-fixes for Ada95 with gnat 4.9

20140906
        + build-fix and other improvements for port of ncurses-examples to
          NetBSD.
        + minor compiler-warning fixes.

20140831
        + modify test/demo_termcap.c and test/demo_terminfo.c to make their
          options more directly comparable, and add "-i" option to specify
          a terminal description filename to parse for names to lookup.

20140823
        + fix special case where double-width character overwrites a single-
          width character in the first column (report by Egmont Koblinger,
          cf: 20050813).

20140816
        + fix colors in ncurses 'b' test which did not work after changing
          it to put the test-strings in subwindows (cf: 20140705).
        + merge redundant SEE-ALSO sections in form and menu manpages.

20140809
        + modify declarations for user-data pointers in C++ binding to use
          reinterpret_cast to facilitate converting typed pointers to void*
          in user's application (patch by Adam Jiang).
        + regenerated html manpages.
        + add note regarding cause and effect for TERM in ncurses manpage,
          having noted clueless verbiage in Terminal.app's "help" file
          which reverses cause/effect.
        + remove special fallback definition for NCURSES_ATTR_T, since macros
          have resolved type-mismatches using casts (cf: 970412).
        + fixes for win_driver.c:
          + handle repainting on endwin/refresh combination.
          + implement beep().
          + minor cleanup.

20140802
        + minor portability fixes for MinGW:
          + ensure WINVER is defined in makefiles rather than using headers
          + add check for gnatprep "-T" option
          + work around bug introduced by gcc 4.8.1 in MinGW which breaks
            "trace" feature:
            http://stackoverflow.com/questions/20877689/gcc-4-8-1-minggw-d-option-does-not-work-as-usual
        + fix most compiler warnings for Cygwin ncurses-examples.
        + restore "redundant" -I options in test/Makefile.in, since they are
          typically needed when building the derived ncurses-examples package
          (cf: 20140726).

20140726
        + eliminate some redundant -I options used for building libraries, and
          ensure that ${srcdir} is added to the include-options (prompted by
          discussion with Paul Gilmartin).
        + modify configure script to work with Minix3.2
        + add form library extension O_DYNAMIC_JUSTIFY option which can be
          used to override the different treatment of justification for static
          versus dynamic fields (adapted from patch by Leon Winter).
        + add a null pointer check in test/edit_field.c (report/analysis by
          Leon Winter, cf: 20130608).

20140719
        + make workarounds for compiling test-programs with NetBSD curses.
        + improve configure macro CF_ADD_LIBS, to eliminate repeated -l/-L
          options, from xterm changes.

20140712
        + correct Charable() macro check for A_ALTCHARSET in wide-characters.
        + build-fix for position-debug code in tty_update.c, to work with or
          without sp-funcs.

20140705
        + add w/W toggle to ncurses.c 'B' test, to demonstrate permutation of
          video-attributes and colors with double-width character strings.

20140629
        + correct check in win_driver.c for saving screen contents, e.g., when
          NCURSES_CONSOLE2 is set (cf: 20140503).
        + reorganize b/B menu items in ncurses.c, putting the test-strings into
          subwindows.  This is needed for a planned change to use Unicode
          fullwidth characters in the test-screens.
        + correct update to form status for _NEWTOP, broken by fixes for
          compiler warnings (patch by Leon Winter, cf: 20120616).

20140621
        + change shared-library suffix for AIX 5 and 6 to ".so", avoiding
          conflict with the static library (report by Ben Lentz).
        + document RPATH_LIST in INSTALLATION file, as part of workarounds for
          upgrading an ncurses library using the "--with-shared" option.
        + modify test/ncurses.c c/C tests to cycle through subsets of the
          total number of colors, to better illustrate 8/16/88/256-colors by
          providing directly comparable screens.
        + add test/dots_curses.c, for comparison with the low-level examples.

20140614
        + fix dereference before null check found by Coverity in tic.c
          (cf: 20140524).
        + fix sign-extension bug in read_entry.c which prevented "toe" from
          reading empty "screen+italics" entry.
        + modify sgr for screen.xterm-new to support dim capability -TD
        + add dim capability to nsterm+7 -TD
        + cancel dim capability for iterm -TD
        + add dim, invis capabilities to vte-2012 -TD
        + add sitm/ritm to konsole-base and mlterm3 -TD

20140609
        > fix regression in screen terminfo entries (reports by Christian
          Ebert, Gabriele Balducci) -TD
        + revert the change to screen; see notes for why this did not work -TD
        + cancel sitm/ritm for entries which extend "screen", to work around
          screen's hardcoded behavior for SGR 3 -TD

20140607
        + separate masking for sgr in vidputs from sitm/ritm, which do not
          overlap with sgr functionality.
        + remove unneeded -i option from adacurses-config; put -a in the -I
          option for consistency (patch by Pascal Pignard).
        + update xterm-new terminfo entry to xterm patch #305 -TD
        + change format of test-scripts for Debian Ada95 and ncurses-examples
          packages to quilted to work around Debian #700177 (cf: 20130907).
        + build fix for form_driver_w.c as part of ncurses-examples package for
          older ncurses than 20131207.
        + add Hello World example to adacurses-config manpage.
        + remove unused --enable-pc-files option from Ada95/configure.
        + add --disable-gnat-projects option for testing.
        + revert changes to Ada95 project-files configuration (cf: 20140524).
        + corrected usage message in adacurses-config.

20140524
        + fix typo in ncurses manpage for the NCURSES_NO_MAGIC_COOKIE
          environment variable.
        + improve discussion of input-echoing in curs_getch.3x
        + clarify discussion in curs_addch.3x of wrapping.
        + modify parametrized.h to make fln non-padded.
        + correct several entries which had termcap-style padding used in
          terminfo: adm21, aj510, alto-h19, att605-pc, x820 -TD
        + correct syntax for padding in some entries: dg211, h19 -TD
        + correct ti924-8 which had confused padding versus octal escapes -TD
        + correct padding in sbi entry -TD
        + fix an old bug in the termcap emulation; "%i" was ignored in tparm()
          because the parameters to be incremented were already on the internal
          stack (report by Corinna Vinschen).
        + modify tic's "-c" option to take into account the "-C" option to
          activate additional checks which compare the results from running
          tparm() on the terminfo expressions versus the translated termcap
          expressions.
        + modify tic to allow it to read from FIFOs (report by Matthieu Fronton,
          cf: 20120324).
        > patches by Nicolas Boulenguez:
        + explicit dereferences to suppress some style warnings.
        + when c_varargs_to_ada.c includes its header, use double quotes
          instead of <>.
        + samples/ncurses2-util.adb:  removed unused with clause.  The warning
          was removed by an obsolete pragma.
        + replaced Unreferenced pragmas with Warnings (Off).  The latter,
          available with older GNATs, needs no configure test.  This also
          replaces 3 untested Unreferenced pragmas.
        + simplified To_C usage in trace handling.  Using two parameters allows
          some basic formatting, and avoids a warning about security with some
          compiler flags.
        + for generated Ada sources, replace many snippets with one pure
          package.
        + removed C_Chtype and its conversions.
        + removed C_AttrType and its conversions.
        + removed conversions between int, Item_Option_Set, Menu_Option_Set.
        + removed int, Field_Option_Set, Item_Option_Set conversions.
        + removed C_TraceType, Attribute_Option_Set conversions.
        + replaced C.int with direct use of Eti_Error, now enumerated.  As it
          was used in a case statement, values were tested by the Ada compiler
          to be consecutive anyway.
        + src/Makefile.in: remove duplicate stanza
        + only consider using a project for shared libraries.
        + style. Silent gnat-4.9 warning about misplaced "then".
        + generate shared library project to honor ADAFLAGS, LDFLAGS.

20140510
        + cleanup recently introduced compiler warnings for MingW port.
        + workaround for ${MAKEFLAGS} configure check versus GNU make 4.0,
          which introduces more than one gratuitous incompatibility.

20140503
        + add vt520ansi terminfo entry (patch by Mike Gran)
        + further improve MinGW support for the scenario where there is an
          ANSI-escapes handler such as ansicon running in the console window
          (patch by Juergen Pfeifer).

20140426
        + add --disable-lib-suffixes option (adapted from patch by Juergen
          Pfeifer).
        + merge some changes from Juergen Pfeifer's work with MSYS2, to
          simplify later merging:
          + use NC_ISATTY() macro for isatty() in library
          + add _nc_mingw_isatty() and related functions to windows-driver
          + rename terminal driver entrypoints to simplify grep's
        + remove a check in the sp-funcs flavor of newterm() which allowed only
          the first call to newterm() to succeed (report by Thomas Beierlein,
          cf: 20090927).

20140419
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20140412
        + modify configure script:
          + drop the -no-gcc option from Intel compiler, from lynx changes.
          + extend the --with-hashed-db configure option to simplify building
            with different versions of Berkeley database using FreeBSD ports.
        + improve initialization for MinGW port (Juergen Pfeifer):
          + enforce Windows-style path-separator if cross-compiling,
          + add a driver-name method to each of the drivers,
          + allow the Windows driver name to match "unknown", ignoring case,
          + lengthen the built-in name for the Windows console driver to
            "#win32console", and
          + move the comparison of driver-names allowing abbreviation, e.g.,
            to "#win32con" into the Windows console driver.

20140329
        + add check in tic for mismatch between ccc and initp/initc
        + cancel ccc in putty-256color and konsole-256color for consistency
          with the cancelled initc capability (patch by Sven Zuhlsdorf).
        + add xterm+256setaf building block for various terminals which only
          get the 256-color feature half-implemented -TD
        + updated "st" entry (leaving the 0.1.1 version as "simpleterm") to
          0.4.1 -TD

20140323
        + fix typo in "mlterm" entry (report by Gabriele Balducci) -TD

20140322
        + use types from <stdint.h> in sample build-scripts for chtype, etc.
        + modify configure script and curses.h.in to allow the types specified
          using --with-chtype and related options to be defined in <stdint.h>
        + add terminology entry -TD
        + add mlterm3 entry, use that as "mlterm" -TD
        + inherit mlterm-256color from mlterm -TD

20140315
        + modify _nc_New_TopRow_and_CurrentItem() to ensure that the menu's
          top-row is adjusted as needed to ensure that the current item is
          on the screen (patch by Johann Klammer).
        + add wgetdelay() to retrieve _delay member of WINDOW if it happens to
          be opaque, e.g., in the pthread configuration (prompted by patch by
          Soren Brinkmann).

20140308
        + modify ifdef in read_entry.c to handle the case where
          NCURSES_USE_DATABASE is not defined (patch by Xin Li).
        + add cast in form_driver_w() to fix ARM build (patch by Xin Li).
        + add logic to win_driver.c to save/restore screen contents when not
          allocating a console-buffer (cf: 20140215).

20140301
        + clarify error-returns from newwin (report by Ruslan Nabioullin).

20140222
        + fix some compiler warnings in win_driver.c
        + updated notes for wsvt25 based on tack and vttest -TD
        + add teken entry to show actual properties of FreeBSD's "xterm"
          console -TD

20140215
        + in-progress changes to win_driver.c to implement output without
          allocating a console-buffer.  This uses a pre-existing environment
          variable NCGDB used by Juergen Pfeifer for debugging (prompted by
          discussion with Erwin Waterlander regarding Console2, which hangs
          when reading in an allocated console-buffer).
        + add -t option to gdc.c, and modify to accept "S" to step through the
          scrolling-stages.
        + regenerate NCURSES-Programming-HOWTO.html to fix some of the broken
          html emitted by docbook.

20140209
        + modify CF_XOPEN_SOURCE macro to omit followup check to determine if
          _XOPEN_SOURCE can/should be defined.  g++ 4.7.2 built on Solaris 10
          has some header breakage due to its own predefinition of this symbol
          (report by Jean-Pierre Flori, Sage #15796).

20140201
        + add/use symbol NCURSES_PAIRS_T like NCURSES_COLOR_T, to illustrate
          which "short" types are for color pairs and which are color values.
        + fix build for s390x, by correcting field bit offsets in generated
          representation clauses when int=32 long=64 and endian=big, or at
          least on s390x (patch by Nicolas Boulenguez).
        + minor cleanup change to test/form_driver_w.c (patch by Gaute Hope).

20140125
        + remove unnecessary ifdef's in Ada95/gen/gen.c, which reportedly do
          not work as is with gcc 4.8 due to fixes using chtype cast made for
          new compiler warnings by gcc 4.8 in 20130824 (Debian #735753, patch
          by Nicolas Boulenguez).

20140118
        + apply includesubdir variable which was introduced in 20130805 to
          gen-pkgconfig.in (Debian #735782).

20131221
        + further improved man2html, used this to fix broken links in html
          manpages.  See
          ftp://ftp.invisible-island.net/ncurses/patches/man2html

20131214
        + modify configure-script/ifdef's to allow OLD_TTY feature to be
          suppressed if the type of ospeed is configured using the option
          --with-ospeed to not be a short.  By default, it is a short for
          termcap-compatibility (adapted from suggestion by Christian
          Weisgerber).
        + correct a typo in _nc_baudrate() (patch by Christian Weisgerber,
          cf: 20061230).
        + fix a few -Wlogical-op warnings.
        + updated llib-l* files.

20131207
        + add form_driver_w() entrypoint to wide-character forms library, as
          well as test program form_driver_w (adapted from patch by Gaute
          Hope).

20131123
        + minor fix for CF_GCC_WARNINGS to special-case options which are not
          recognized by clang.

20131116
        + add special case to configure script to move _XOPEN_SOURCE_EXTENDED
          definition from CPPFLAGS to CFLAGS if it happens to be needed for
          Solaris, because g++ errors with that definition (report by
          Jean-Pierre Flori, Sage #15268).
        + correct logic in infocmp's -i option which was intended to ignore
          strings which correspond to function-keys as candidates for piecing
          together initialization- or reset-strings.  The problem dates to
          1.9.7a, but was overlooked until changes in -Wlogical-op warnings for
          gcc 4.8 (report by David Binderman).
        + updated CF_GCC_WARNINGS to documented options for gcc 4.9.0, moving
          checks for -Wextra and -Wdeclaration-after-statement into the macro,
          and adding checks for -Wignored-qualifiers, -Wlogical-op and
          -Wvarargs

20130907
        + build-fixes for MSYS for two test-programs (patches by Ray Donnelly,
          Alexey Pavlov).
        + revert change to two of the dpkg format files, to work with dpkg
          before/after Debian #700177.
        + fix gcc -Wconversion warning in wattr_get() macro.
        + add msys and msysdll to known host/configuration types (patch by
          Alexey Pavlov).
        + modify CF_RPATH_HACK configure macro to not rely upon "-u" option
          of sort, improving portability.
        + minor improvements for test-programs from reviewing Solaris port.
        + update config.guess, config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20130831
        + modify test/ncurses.c b/B tests to display lines only for the
          attributes which a given terminal supports, to make room for an
          italics test.
        + completed ncv table in terminfo.tail; it did not list the wide
          character codes listed in X/Open Curses issue 7.
        + add A_ITALIC extension (prompted by discussion with Egmont Koblinger).

20130824
        + fix some gcc 4.8 -Wconversion warnings.
        + change format of dpkg test-scripts to quilted to work around bug
          introduced by Debian #700177.
        + discard cached keyname() values if meta() is changed after a value

20130816
        + add checks in tic to warn about terminals which lack cursor
          addressing, capabilities or having those, are marked as hard_copy or
          generic_type.
        + use --without-progs in mingw-ncurses rpm.
        + split out _nc_init_termtype() from alloc_entry.c to use in MinGW
          port when tic and other programs are not needed.

20130805
        + minor fixes to the --disable-overwrite logic, to ensure that the
          configured $(includedir) is not cancelled by the mingwxx-filesystem
          rpm macros.
        + add --disable-db-install configure option, to simplify building
          cross-compile support packages.
        + add mingw-ncurses.spec file, for testing cross-compiles.

          + CF_ADD_LIB_AFTER - fix a problem with -Wl options
          + CF_RPATH_HACK - add missing result-message
          + CF_SHARED_OPTS - modify to use $rel_builddir in cygwin and mingw
            dll symbols (which can be overridden) rather than explicit "../".
          + CF_SHARED_OPTS - modify NetBSD and DragonFly symbols to use ${CC}

        + quiet linker warnings for MinGW cross-compile with dll's using the
          --enable-auto-import flag.
        + add ncurses.map rule to ncurses/Makefile to help diagnose symbol
          table issues.

20130622
        + modify the clear program to take into account the E3 extended
          capability to clear the terminal's scrollback buffer (patch by
          Miroslav Lichvar, Redhat #815790).
        + clarify in resizeterm manpage that LINES and COLS are updated.
        + updated ansi example in terminfo.tail, correct misordered example
          of sgr.
        + fix other doclifter warnings for manpages

          (patch by Eric Raymond).

20130615
        + minor changes to some configure macros to make them more reusable.
        + fixes for tabs program (prompted by report by Nick Andrik).
          + corrected logic in command-line parsing of -a and -c predefined
            tab-lists options.
          + allow "-0" and "-8" options to be combined with others, e.g.,"-0d".
          + make warning messages more consistent with the other utilities by
            not printing the full pathname of the program.
          + add -V option for consistency with other utilities.
        + fix off-by-one in columns for tabs program when processing an option

        + add to test/demo_forms.c examples of using the menu-hooks as well
          as showing how the menu item user-data can be used to pass a callback
          function pointer.
        + add test/dots_termcap.c
        + remove setupterm call from test/demo_termcap.c
        + build-fix if --disable-ext-funcs configure option is used.
        + modified test/edit_field.c and test/demo_forms.c to move the lengths

          expansion to free-format input/out demo.
        + modified test/demo_forms.c to load data from file.
        + added note to clarify Terminal.app's non-emulation of the various

        + fix regression in error-reporting in lib_setup.c (Debian #711134,
          cf: 20121117).
        + build-fix for a case where --enable-broken_linker and
          --enable-reentrant options are combined (report by George R Goffe).

20130525
        + modify mvcur() to distinguish between internal use by the ncurses
          library, and external callers, preventing it from reading the content
          of the screen which is only nonblank when curses calls have updated
          it.  This makes test/dots_mvcur.c avoid painting colored cells in
          the left margin of the display.
        + minor fix to test/dots_mvcur.c
        + move configured symbols USE_DATABASE and USE_TERMCAP to term.h as
          NCURSES_USE_DATABASE and NCURSES_USE_TERMCAP to allow consistent
          use of these symbols in term_entry.h

20130518
        + corrected ifdefs in test/testcurs.c to allow comparison of mouse
          interface versus pdcurses (cf: 20130316).
        + add pow() to configure-check for math library, needed since
          20121208 for test/hanoi (Debian #708056).

        + additional cleanup of table-of-contents by reordering -TD
        + revise fix for check for 8-bit value in _nc_insert_ch(); prior fix
          prevented inserts when video attributes were attached to the data
          (cf: 20121215) (Redhat #959534).

20130504
        + fixes for issues found by Coverity:
          + correct FNKEY() macro in progs/dump_entry.c, allowing kf11-kf63 to
            display when infocmp's -R option is used for HP or AIX subsets.
          + fix dead-code issue with test/movewindow.c
          + improve limited-checking in _nc_read_termtype().

20130427
        + fix clang 3.2 warning in progs/dump_entry.c
        + drop AC_TYPE_SIGNAL check; ncurses relies on c89 and later.

20130413
        + add MinGW to cases where ncurses installs by default into /usr
          (prompted by discussion with Daniel Silva Ferreira).
        + add -D option to infocmp's usage-message (patch by Miroslav Lichvar).
        + add a missing 'int' type for main function in configure check for
          type of bool variable, to work with clang 3.2 (report by Dmitri
          Gribenko).
        + improve configure check for static_cast, to work with clang 3.2
          (report by Dmitri Gribenko).
        + re-order rule for demo.o and macros defining header dependencies in
          c++/Makefile.in to accommodate gmake (report by Dmitri Gribenko).

20130406
        + improve parameter checking in copywin().
        + modify configure script to work around OS X's "libtool" program, to
          choose glibtool instead.  At the same time, chance the autoconf macro
          to look for a "tool" rather than a "prog", to help with potential use
          in cross-compiling.
        + separate the rpath usage for c++ library from demo program
          (Redhat #911540)
        + update/correct header-dependencies in c++ makefile (report by Werner
          Fink).
        + add --with-cxx-shared to dpkg-script, as done for rpm-script.

20130324
        + build-fix for libtool configuration (reports by Daniel Silva Ferreira
          and Roumen Petrov).

20130323
        + build-fix for OS X, to handle changes for --with-cxx-shared feature
          (report by Christian Ebert).
        + change initialization for vt220, similar entries for consistency
          with cursor-key strings (NetBSD #47674) -TD
        + further improvements to linux-16color (Benjamin Sittler)

20130316
        + additional fix for tic.c, to allocate missing buffer space.
        + eliminate configure-script warnings for gen-pkgconfig.in
        + correct typo in sgr string for sun-color,
          add bold for consistency with sgr,
          change smso for consistency with sgr -TD
        + correct typo in sgr string for terminator -TD
        + add blink to the attributes masked by ncv in linux-16color (report
          by Benjamin Sittler)
        + improve warning message from post-load checking for missing "%?"
          operator by tic/infocmp by showing the entry name and capability.
        + minor formatting improvement to tic/infocmp -f option to ensure
          line split after "%;".
        + amend scripting for --with-cxx-shared option to handle the debug
          library "libncurses++_g.a" (report by Sven Joachim).

20130309
        + amend change to toe.c for reading from /dev/zero, to ensure that
          there is a buffer for the temporary filename (cf: 20120324).
        + regenerated html manpages.
        + fix typo in terminfo.head (report by Sven Joachim, cf: 20130302).
        + updated some autoconf macros:
          + CF_ACVERSION_CHECK, from byacc 1.9 20130304
          + CF_INTEL_COMPILER, CF_XOPEN_SOURCE from luit 2.0-20130217
        + add configure option --with-cxx-shared to permit building
          libncurses++ as a shared library when using g++, e.g., the same
          limitations as libtool but better integrated with the usual build
          configuration (Redhat #911540).
        + modify MKkey_defs.sh to filter out build-path which was unnecessarily
          shown in curses.h (Debian #689131).

20130302
        + add section to terminfo manpage discussing user-defined capabilities.
        + update manpage description of NCURSES_NO_SETBUF, explaining why it
          is obsolete.
        + add a check in waddch_nosync() to ensure that tab characters are
          treated as control characters; some broken locales claim they are
          printable.
        + add some traces to the Windows console driver.
        + initialize a temporary array in _nc_mbtowc, needed for some cases
          of raw input in MinGW port.

20130218
        + correct ifdef on change to lib_twait.c (report by  Werner Fink).
        + update config.guess, config.sub

20130216
        + modify test/testcurs.c to work with mouse for ncurses as it does for
          pdcurses.
        + modify test/knight.c to work with mouse for pdcurses as it does for
          ncurses.
        + modify internal recursion in wgetch() which handles cooked mode to
          check if the call to wgetnstr() returned an error.  This can happen
          when both nocbreak() and nodelay() are set, for instance (report by
          Nils Christopher Brause) (cf: 960418).
        + fixes for issues found by Coverity:
          + add a check for valid position in ClearToEOS()
          + fix in lib_twait.c when --enable-wgetch-events is used, pointer
            use after free.
          + improve a limit-check in make_hash.c
          + fix a memory leak in hashed_db.c

20130209
        + modify test/configure script to make it simpler to override names
          of curses-related libraries, to help with linking with pdcurses in
          MinGW environment.
        + if the --with-terminfo-dirs configure option is not used, there is
          no corresponding compiled-in value for that.  Fill in "no default
          value" for that part of the manpage substitution.

20130202
        + correct initialization in knight.c which let it occasionally make
          an incorrect move (cf: 20001028).
        + improve documentation of the terminfo/termcap search path.

20130126
        + further fixes to mvcur to pass callback function (cf: 20130112),
          needed to make test/dots_mvcur work.
        + reduce calls to SetConsoleActiveScreenBuffer in win_driver.c, to
          help reduce flicker.
        + modify configure script to omit "+b" from linker options for very
          old HP-UX systems (report by Dennis Grevenstein)
        + add HP-UX workaround for missing EILSEQ on old HP-UX systems (patch
          by Dennis Grevenstein).
        + restore memmove/strdup support for antique systems (request by
          Dennis Grevenstein).
        + change %l behavior in tparm to push the string length onto the stack
          rather than saving the formatted length into the output buffer
          (report by Roy Marples, cf: 980620).

20130119
        + fixes for issues found by Coverity:
          + fix memory leak in safe_sprintf.c
          + add check for return-value in tty_update.c
          + correct initialization for -s option in test/view.c
          + add check for numeric overflow in lib_instr.c
          + improve error-checking in copywin
        + add advice in infocmp manpage for termcap users (Debian #698469).
        + add "-y" option to test/demo_termcap and test/demo_terminfo to
          demonstrate behavior with/without extended capabilities.
        + updated termcap manpage to document legacy termcap behavior for
          matching capability names.
        + modify name-comparison for tgetstr, etc., to accommodate legacy
          applications as well as to improve compatibility with BSD 4.2
          termcap implementations (Debian #698299) (cf: 980725).

20130112
        + correct prototype in manpage for vid_puts.
        + drop ncurses/tty/tty_display.h, ncurses/tty/tty_input.h, since they
          are unused in the current driver model.
        + modify mvcur to use stdout except when called within the ncurses
          library.
        + modify vidattr and vid_attr to use stdout as documented in manpage.
        + amend changes made to buffering in 20120825 so that the low-level
          putp() call uses stdout rather than ncurses' internal buffering.
          The putp_sp() call does the same, for consistency (Redhat #892674).

20130105
        + add "-s" option to test/view.c to allow it to start in single-step
          mode, reducing size of trace files when it is used for debugging
          MinGW changes.
        + revert part of 20121222 change to tinfo_driver.c
        + add experimental logic in win_driver.c to improve optimization of
          screen updates.  This does not yet work with double-width characters,
          so it is ifdef'd out for the moment (prompted by report by Erwin
          Waterlander regarding screen flicker).

20121229
        + fix Coverity warnings regarding copying into fixed-size buffers.
        + add throw-declarations in the c++ binding per Coverity warning.
        + minor changes to new-items for consistent reference to bug-report
          numbers.

20121222
        + add *.dSYM directories to clean-rule in ncurses directory makefile,
          for Mac OS builds.
        + add a configure check for gcc option -no-cpp-precomp, which is not
          available in all Mac OS X configurations (report by Andras Salamon,
          cf: 20011208).
        + improve 20021221 workaround for broken acs, handling a case where
          that ACS_xxx character is not in the acsc string but there is a known
          wide-character which can be used.

20121215

20121208
        + modify test/knight.c to show the number of choices possible for
          each position in automove option, e.g., to allow user to follow
          Warnsdorff's rule to solve the puzzle.
        + modify test/hanoi.c to show the minimum number of moves possible for
          the given number of tiles (prompted by patch by Lucas Gioia).
        > fixes based on Coverity report:
        + remove a few redundant checks.

          used.

20121201
        + also replace MinGW's wctomb(), fixing a problem with setcchar().
        + modify test/view.c to load UTF-8 when built with MinGW by using
          regular win32 API because the MinGW functions mblen() and mbtowc()
          do not work.

20121124
        + correct order of color initialization versus display in some of the
          test-programs, e.g., test_addstr.c
        > fixes based on Coverity report:
        + delete windows on exit from some of the test-programs.

20121117
        > fixes based on Coverity report:
        + add missing braces around FreeAndNull in two places.
        + various fixes in test/ncurses.c
        + improve limit-checks in tinfo/make_hash.c, tinfo/read_entry.c
        + correct malloc size in progs/infocmp.c
        + guard against negative array indices in test/knight.c
        + fix off-by-one limit check in test/color_name.h
        + add null-pointer check in progs/tabs.c, test/bs.c, test/demo_forms.c,
          test/inchs.c
        + fix memory-leak in tinfo/lib_setup.c, progs/toe.c,
          test/clip_printw.c, test/demo_menus.c
        + delete unused windows in test/chgat.c, test/clip_printw.c,
          test/insdelln.c, test/newdemo.c on error-return.

20121110
        + modify configure macro CF_INCLUDE_DIRS to put $CPPFLAGS after the
          local -I include options in case someone has set conflicting -I
          options in $CPPFLAGS (prompted by patch for ncurses/Makefile.in by
          Vassili Courzakis).
        + modify the ncurses*-config scripts to eliminate relative paths from
          the RPATH_LIST variable, e.g., "../lib" as used in installing shared
          libraries or executables.

20121102
        + realign these related pages:
            curs_add_wchstr.3x
            curs_addchstr.3x
            curs_addstr.3x
            curs_addwstr.3x
          and fix a long-ago error in curs_addstr.3x which said that a -1
          length parameter would only write as much as fit onto one line
          (report by Reuben Thomas).
        + remove obsolete fallback _nc_memmove() for memmove()/bcopy().
        + remove obsolete fallback _nc_strdup() for strdup().
        + cancel any debug-rpm in package/ncurses.spec
        + reviewed vte-2012, reverted most of the change since it was incorrect
          based on testing with tack -TD
        + un-cancel the initc in vte-256color, since this was implemented
          starting with version 0.20 in 2009 -TD

20121026
        + improve malloc/realloc checking (prompted by discussion in Redhat
          #866989).
        + add ncurses test-program as "ncurses6" to the rpm- and dpkg-scripts.
        + updated configure macros CF_GCC_VERSION and CF_WITH_PATHLIST.  The
          first corrects pattern used for Mac OS X's customization of gcc.

20121017
        + fix change to _nc_scroll_optimize(), which incorrectly freed memory
          (Redhat #866989).

20121013
        + add vte-2012, gnome-2012, making these the defaults for vte/gnome
          (patch by Christian Persch).

20121006
        + improve CF_GCC_VERSION to work around Debian's customization of gcc
          --version message.
        + improve configure macros as done in byacc:
          + drop 2.13 compatibility; use 2.52.xxxx version only since EMX port
            has used that for a while.
          + add 3rd parameter to AC_DEFINE's to allow autoheader to run, i.e.,
            for experimental use.
          + remove unused configure macros.
        + modify configure script and makefiles to quiet new autoconf warning
          for LIBS_TO_MAKE variable.

        + modify setupterm to set its copy of TERM to "unknown" if configured
          for the terminal driver and TERM was null or empty.
        + modify treatment of TERM variable for MinGW port to allow explicit
          use of the windows console driver by checking if $TERM is set to
          "#win32con" or an abbreviation of that.
        + undo recent change to fallback definition of vsscanf() to build with
          older Solaris compilers (cf: 20120728).

20120908
        + add test-screens to test/ncurses to show 256-characters at a time,
          to help with MinGW port.

20120903
        + simplify varargs logic in lib_printw.c; va_copy is no longer needed
          there.
        + modifications for MinGW port to make wide-character display usable.

20120902
        + regenerate configure script (report by Sven Joachim, cf: 20120901).

20120901
        + add a null-pointer check in _nc_flush (cf: 20120825).
        + fix a case in _nc_scroll_optimize() where the _oldnums_list array
          might not be allocated.
        + improve comparisons in configure.in for unset shell variables.

20120826
        + increase size of ncurses' output-buffer, in case of very small
          initial screen-sizes.
        + fix evaluation of TERMINFO and TERMINFO_DIRS default values as needed
          after changes to use --datarootdir (reports by Gabriele Balducci,
          Roumen Petrov).

20120825
        + change output buffering scheme, using buffer maintained by ncurses
          rather than stdio, to avoid problems with SIGTSTP handling (report
          by Brian Bloniarz).

20120811
        + update autoconf patch to 2.52.20120811, adding --datarootdir
          (prompted by discussion with Erwin Waterlander).
        + improve description of --enable-reentrant option in README and the
          INSTALL file.
        + add nsterm-256color, make this the default nsterm -TD
        + remove bw from nsterm-bce, per testing with tack -TD

20120804
        + update test/configure, adding check for tinfo library.
        + improve limit-checks for the getch fifo (report by Werner Fink).
        + fix a remaining mismatch between $with_echo and the symbols updated
          for CF_DISABLE_ECHO affecting parameters for mk-2nd.awk (report by
          Sven Joachim, cf:  20120317).
        + modify followup check for pkg-config's library directory in the
          --enable-pc-files option to validate syntax (report by Sven Joachim,
          cf: 20110716).

20120728
        + correct path for ncurses_mingw.h in include/headers, in case build
          is done outside source-tree (patch by Roumen Petrov).
        + modify some older xterm entries to align with xterm source -TD
        + separate "xterm-old" alias from "xterm-r6" -TD
        + add E3 extended capability to xterm-basic and putty -TD
        + parenthesize parameters of other macros in curses.h -TD
        + parenthesize parameter of COLOR_PAIR and PAIR_NUMBER in curses.h
          in case it happens to be a comma-expression, etc.  (patch by Nick
          Black).

20120721
        + improved form_request_by_name() and menu_request_by_name().
        + eliminate two fixed-size buffers in toe.c
        + extend use_tioctl() to have expected behavior when use_env(FALSE) and
          use_tioctl(TRUE) are called.
        + modify ncurses test-program, adding -E and -T options to demonstrate
          use_env() versus use_tioctl().

20120714
        + add use_tioctl() function (adapted from patch by Werner Fink,
          Novell #769788):

20120707
        + add ncurses_mingw.h to installed headers (prompted by patch by
          Juergen Pfeifer).
        + clarify return-codes from wgetch() in response to SIGWINCH (prompted
          by Novell #769788).
        + modify resizeterm() to always push a KEY_RESIZE onto the fifo, even
          if screensize is unchanged.  Modify _nc_update_screensize() to push a
          KEY_RESIZE if there was a SIGWINCH, even if it does not call
          resizeterm().  These changes eliminate the case where a SIGWINCH is
          received, but ERR returned from wgetch or wgetnstr because the screen
          dimensions did not change (Novell #769788).

20120630
        + add --enable-interop to sample package scripts (suggested by Juergen
          Pfeifer).
        + update CF_PATH_SYNTAX macro, from mawk changes.
        + modify mk-0th.awk to allow for generating llib-ltic, etc., though
          some work is needed on cproto to work with lib_gen.c to update
          llib-lncurses.
        + remove redundant getenv() cal in database-iterator leftover from
          cleanup in 20120622 changes (report by Sven Joachim).

20120622
        + add -d, -e and -q options to test/demo_terminfo and test/demo_termcap
        + fix caching of environment variables in database-iterator (patch by
          Philippe Troin, Redhat #831366).

20120616
        + add configure check to distinguish clang from gcc to eliminate
          warnings about unused command-line parameters when compiler warnings
          are enabled.
        + improve behavior when updating terminfo entries which are hardlinked
          by allowing for the possibility that an alias has been repurposed to
          a new primary name.
        + fix some strict compiler warnings based on package scripts.
        + further fixes for configure check for working poll (Debian #676461).

20120608
        + fix an uninitialized variable in -c/-n logic for infocmp changes
          (cf: 20120526).
        + corrected fix for building c++ binding with clang 3.0 (report/patch
          by Richard Yao, Gentoo #417613, cf: 20110409)
        + correct configure check for working poll, fixing the case where stdin
          is redirected, e.g., in rpm/dpkg builds (Debian #676461).
        + add rpm- and dpkg-scripts, to test those build-environments.
          The resulting packages are used only for testing.

20120602
        + add kdch1 aka "Remove" to vt220 and vt220-8 entries -TD
        + add kdch1, etc., to qvt108 -TD
        + add dl1/il1 to some entries based on dl/il values -TD
        + add dl to simpleterm -TD
        + add consistency-checks in tic for insert-line vs delete-line
          controls, and insert/delete-char keys
        + correct no-leaks logic in infocmp when doing comparisons, fixing
          duplicate free of entries given via the command-line, and freeing
          entries loaded from the last-but-one of files specified on the
          command-line.
        + add kdch1 to wsvt25 entry from NetBSD CVS (reported by David Lord,
          analysis by Martin Husemann).
        + add cnorm/civis to wsvt25 entry from NetBSD CVS (report/analysis by
          Onno van der Linden).

20120526
        + extend -c and -n options of infocmp to allow comparing more than two
          entries.
        + correct check in infocmp for number of terminal names when more than
          two are given.
        + correct typo in curs_threads.3x (report by Yanhui Shen on
          freebsd-hackers mailing list).

20120512
        + corrected 'op' for bterm (report by Samuel Thibault) -TD
        + modify test/background.c to demonstrate a background character
          holding a colored ACS_HLINE.  The behavior differs from SVr4 due to
          the thick- and double-line extension (cf: 20091003).
        + modify handling of acs characters in PutAttrChar to avoid mapping an
          unmapped character to a space with A_ALTCHARSET set.
        + rewrite vt520 entry based on vt420 -TD

20120505
        + remove p6 (bold) from opus3n1+ for consistency -TD
        + remove acs stuff from env230 per clues in Ingres termcap -TD
        + modify env230 sgr/sgr0 to match other capabilities -TD
        + modify smacs/rmacs in bq300-8 to match sgr/sgr0 -TD
        + make sgr for dku7202 agree with other caps -TD
        + make sgr for ibmpc agree with other caps -TD
        + make sgr for tek4107 agree with other caps -TD
        + make sgr for ndr9500 agree with other caps -TD
        + make sgr for sco-ansi agree with other caps -TD
        + make sgr for d410 agree with other caps -TD
        + make sgr for d210 agree with other caps -TD
        + make sgr for d470c, d470c-7b agree with other caps -TD
        + remove redundant AC_DEFINE for NDEBUG versus Makefile definition.
        + fix a back-link in _nc_delink_entry(), which is needed if ncurses is
          configured with --enable-termcap and --disable-getcap.

20120428
        + fix some inconsistencies between vt320/vt420, e.g., cnorm/civis -TD
        + add eslok flag to dec+sl -TD
        + dec+sl applies to vt320 and up -TD
        + drop wsl width from xterm+sl -TD
        + reuse xterm+sl in putty and nsca-m -TD
        + add ansi+tabs to vt520 -TD
        + add ansi+enq to vt220-vt520 -TD
        + fix a compiler warning in example in ncurses-intro.doc (Paul Waring).
        + added paragraph in keyname manpage telling how extended capabilities
          are interpreted as key definitions.
        + modify tic's check of conflicting key definitions to include extended
          capability strings in addition to the existing check on predefined
          keys.

20120421
        + improve cleanup of temporary files in tic using atexit().
        + add msgr to vt420, similar DEC vtXXX entries -TD
        + add several missing vt420 capabilities from vt220 -TD
        + factor out ansi+pp from several entries -TD
        + change xterm+sl and xterm+sl-twm to include only the status-line
          capabilities and not "use=xterm", making them more generally useful
          as building-blocks -TD
        + add dec+sl building block, as example -TD

20120414
        + add XT to some terminfo entries to improve usefulness for other
          applications than screen, which would like to pretend that xterm's
          title is a status-line.  -TD
        + change use-clauses in ansi-mtabs, hp2626, and hp2622 based on review
          of ordering and overrides -TD
        + add consistency check in tic for screen's "XT" capability.
        + add section in terminfo.src summarizing the user-defined capabilities
          used in that file -TD

20120407
        + fix an inconsistency between tic/infocmp "-x" option; tic omits all
          non-standard capabilities, while infocmp was ignoring only the user
          definable capabilities.
        + improve special case in tic parsing of description to allow it to be
          followed by terminfo capabilities.  Previously the description had to
          be the last field on an input line to allow tic to distinguish
          between termcap and terminfo format while still allowing commas to be
          embedded in the description.
        + correct variable name in gen_edit.sh which broke configurability of
          the --with-xterm-kbs option.
        + revert 2011-07-16 change to "linux" alias, return to "linux2.2" -TD
        + further amend 20110910 change, providing for configure-script
          override of the "linux" terminfo entry to install and changing the
          default for that to "linux2.2" (Debian #665959).

20120331
        + update Ada95/configure to use CF_DISABLE_ECHO (cf: 20120317).
        + correct order of use-clauses in st-256color -TD
        + modify configure script to look for gnatgcc if the Ada95 binding
          is built, in preference to the default gcc/cc (suggested by
          Nicolas Boulenguez).
        + modify configure script to ensure that the same -On option used for
          the C compiler in CFLAGS is used for ADAFLAGS rather than simply
          using "-O3" (suggested by Nicolas Boulenguez)

20120324
        + amend an old fix so that next_char() exits properly for empty files,
          e.g., from reading /dev/null (cf: 20080804).
        + modify tic so that it can read from the standard input, or from
          a character device.  Because tic uses seek's, this requires writing
          the data to a temporary file first (prompted by remark by Sven
          Joachim) (cf: 20000923).

20120317
        + correct a check made in lib_napms.c, so that terminfo applications
          can again use napms() (cf: 20110604).
        + add a note in tic.h regarding required casts for ABSENT_BOOLEAN
          (cf: 20040327).
        + correct scripting for --disable-echo option in test/configure.
        + amend check for missing c++ compiler to work when no error is
          reported, and no variables set (cf: 20021206).
        + add/use configure macro CF_DISABLE_ECHO.

20120310
        + fix some strict compiler warnings for abi6 and 64-bits.
        + use begin_va_copy/end_va_copy macros in lib_printw.c (cf: 20120303).
        + improve a limit-check in infocmp.c (Werner Fink):

20120303
        + minor tidying of terminfo.tail, clarify reason for limitation
          regarding mapping of \0 to \200
        + minor improvement to _nc_copy_termtype(), using memcpy to replace
          loops.
        + fix no-leaks checking in test/demo_termcap.c to account for multiple
          calls to setupterm().
        + modified the libgpm change to show previous load as a problem in the
          debug-trace.
        > merge some patches from OpenSUSE rpm (Werner Fink):
        + ncurses-5.7-printw.dif, fixes for varargs handling in lib_printw.c
        + ncurses-5.7-gpm.dif, do not dlopen libgpm if already loaded by
          runtime linker
        + ncurses-5.6-fallback.dif, do not free arrays and strings from static
          fallback entries

20120228
        + fix breakage in tic/infocmp from 20120225 (report by Werner Fink).

20120225
        + modify configure script to allow creating dll's for MinGW when
          cross-compiling.
        + add --enable-string-hacks option to control whether strlcat and
          strlcpy may be used.  The same issue applies to OpenBSD's warnings
          about snprintf, noting that this function is weakly standardized.
        + add configure checks for strlcat, strlcpy and snprintf, to help
          reduce bogus warnings with OpenBSD builds.
        + build-fix for OpenBSD 4.9 to supply consistent intptr_t declaration
          (cf:20111231)
        + update config.guess, config.sub

20120218
        + correct CF_ETIP_DEFINES configure macro, making it exit properly on
          the first success (patch by Pierre Labastie).
        + improve configure macro CF_MKSTEMP by moving existence-check for
          mkstemp out of the AC_TRY_RUN, to help with cross-compiles.
        + improve configure macro CF_FUNC_POLL from luit changes to detect
          broken implementations, e.g., with Mac OS X.
        + add configure option --with-tparm-arg
        + build-fix for MinGW cross-compiling, so that make_hash does not
          depend on TTY definition (cf: 20111008).

        + make sgr for cygwin, cygwinDBG agree with other caps -TD
        + add configure option --with-xterm-kbs to simplify configuration for
          Linux versus most other systems.

20120204
        + improved tic -D option, avoid making target directory and provide
          better diagnostics.

20120128
        + add mach-gnu (Debian #614316, patch by Samuel Thibault)
        + add mach-gnu-color, tweaks to mach-gnu terminfo -TD
        + make sgr for sun-color agree with smso -TD

        + make sgr for avt-ns agree with other caps -TD
        + amend fix intended to separate fixups for acsc to allow "tic -cv" to
          give verbose warnings (cf:  20110730).
        + modify misc/gen-edit.sh to make the location of the tabset directory
          consistent with misc/Makefile.in, i.e., using ${datadir}/tabset
          (Debian #653435, patch by Sven Joachim).

20120121
        + add --with-lib-prefix option to allow configuring for old/new flavors
          of OS/2 EMX.
        + modify check for gnat version to allow for year, as used in FreeBSD
          port.
        + modify check_existence() in db_iterator.c to simply check if the
          path is a directory or file, according to the need.  Checking for
          directory size also gives no usable result with OS/2 (cf: 20120107).
        + support OS/2 kLIBC (patch by KO Myung-Hun).

20120114
        + several improvements to test/movewindow.c (prompted by discussion on
          Linux Mint forum):
          + modify movement commands to make them continuous
          + rewrote the test for mvderwin
          + rewrote the test for recursive mvwin
        + split-out reusable CF_WITH_NCURSES_ETC macro in test/configure.in
        + updated configure macro CF_XOPEN_SOURCE, build-fixes for Mac OS X
          and OpenBSD.
        + regenerated html manpages.

20120107
        + various improvements for MinGW (Juergen Pfeifer):
          + modify stat() calls to ignore the st_size member
          + drop mk-dlls.sh script.
          + change recommended regular expression library.
          + modify rain.c to allow for threaded configuration.
          + modify tset.c to allow for case when size-change logic is not used.

20111231
        + modify toe's report when -a and -s options are combined, to add
          a column showing which entries belong to a given database.
        + add -s option to toe, to sort its output.
        + modify progs/toe.c, simplifying use of db-iterator results to use
          caching improvements from 20111001 and 20111126.
        + correct generation of pc-files when ticlib or termlib options are
          given to rename the corresponding tic- or tinfo-libraries (report
          by Sven Joachim).

20111224
        + document a portability issue with tput, i.e., that scripts which work
          with ncurses may fail in other implementations that do no parameter
          analysis.
        + add putty-sco entry -TD

20111217
        + review/fix places in manpages where --program-prefix configure option
          was not being used.
        + add -D option to infocmp, to show the database locations that it
          could use.
        + fix build for the special case where term-driver, ticlib and termlib
          are all enabled.  The terminal driver depends on a few features in
          the base ncurses library, so tic's dependencies include both ncurses
          and termlib.
        + fix build work for term-driver when --enable-wgetch-events option is
          enabled.
        + use <stdint.h> types to fix some questionable casts to void*.

20111210
        + modify configure script to check if thread library provides
          pthread_mutexattr_settype(), e.g., not provided by Solaris 2.6
        + modify configure script to suppress check to define _XOPEN_SOURCE
          for IRIX64, since its header files have a conflict versus
          _SGI_SOURCE.
        + modify configure script to add ".pc" files for tic- and
          tinfo-libraries, which were omitted in recent change (cf: 20111126).
        + fix inconsistent checks on $PKG_CONFIG variable in configure script.

20111203
        + modify configure-check for etip.h dependencies, supplying a temporary
          copy of ncurses_dll.h since it is a generated file (prompted by
          Debian #646977).
        + modify CF_CPP_PARAM_INIT "main" function to work with current C++.

20111126
        + correct database iterator's check for duplicate entries
          (cf: 20111001).
        + modify database iterator to ignore $TERMCAP when it is not an
          absolute pathname.
        + add -D option to tic, to show the database locations that it could
          use.
        + improve description of database locations in tic manpage.
        + modify the configure script to generate a list of the ".pc" files to
          generate, rather than deriving the list from the libraries which have
          been built (patch by Mike Frysinger).
        + use AC_CHECK_TOOLS in preference to AC_PATH_PROGS when searching for
          ncurses*-config, e.g., in Ada95/configure and test/configure (adapted
          from patch by Mike Frysinger).

20111119
        + remove obsolete/conflicting fallback definition for _POSIX_SOURCE
          from curses.priv.h, fixing a regression with IRIX64 and Tru64
          (cf: 20110416)
        + modify _nc_tic_dir() to ensure that its return-value is nonnull,
          i.e., the database iterator was not initialized.  This case is needed
          to when tic is translating to termcap, rather than loading the
          database (cf:  20111001).

20111112
        + add pccon entries for OpenBSD console (Alexei Malinin).
        + build-fix for OpenBSD 4.9 with gcc 4.2.1, setting _XOPEN_SOURCE to
          600 to work around inconsistent ifdef'ing of wcstof between C and
          C++ header files.
        + modify capconvert script to accept more than exact match on "xterm",
          e.g., the "xterm-*" variants, to exclude from the conversion (patch
          by Robert Millan).
        + add -lc_r as alternative for -lpthread, allows build of threaded code
          in older FreeBSD machines.
        + build-fix for MirBSD, which fails when either _XOPEN_SOURCE or
          _POSIX_SOURCE are defined.
        + fix a typo misc/Makefile.in, used in uninstalling pc-files.

20111030
        + modify make_db_path() to allow creating "terminfo.db" in the same
          directory as an existing "terminfo" directory.  This fixes a case
          where switching between hashed/filesystem databases would cause the
          new hashed database to be installed in the next best location -
          root's home directory.
        + add variable cf_cv_prog_gnat_correct to those passed to
          config.status, fixing a problem with Ada95 builds (cf: 20111022).
        + change feature test from _XPG5 to _XOPEN_SOURCE in two places, to
          accommodate broken implementations for _XPG6.
        + eliminate usage of NULL symbol from etip.h, to reduce header
          interdependencies.
        + add configure check to decide when to add _XOPEN_SOURCE define to
          compiler options, i.e., for Solaris 10 and later (cf: 20100403).
          This is a workaround for gcc 4.6, which fails to build the c++
          binding if that symbol is defined by the application, due to
          incorrectly combining the corresponding feature test macros
          (report by Peter Kruse).

20111022
        + correct logic for discarding mouse events, retaining the partial
          events used to build up click, double-click, etc, until needed
          (cf: 20110917).
        + fix configure script to avoid creating unused Ada95 makefile when
          gnat does not work.
        + cleanup width-related gcc 3.4.3 warnings for 64-bit platform, for the
          internal functions of libncurses.  The external interface of courses
          uses bool, which still produces these warnings.

20111015
        + improve description of --disable-tic-depends option to make it
          clear that it may be useful whether or not the --with-termlib
          option is also given (report by Sven Joachim).
        + amend termcap equivalent for set_pglen_inch to use the X/Open
          "YI" rather than the obsolete Solaris 2.5 "sL" (cf: 990109).
        + improve manpage for tgetent differences from termcap library.

20111008
        + moved static data from db_iterator.c to lib_data.c
        + modify db_iterator.c for memory-leak checking, fix one leak.
        + modify misc/gen-pkgconfig.in to use Requires.private for the parts
          of ncurses rather than Requires, as well as Libs.private for the
          other library dependencies (prompted by Debian #644728).

20111001
        + modify tic "-K" option to only set the strict-flag rather than force
          source-output.  That allows the same flag to control the parser for
          input and output of termcap source.
        + modify _nc_getent() to ignore backslash at the end of a comment line,
          making it consistent with ncurses' parser.
        + restore a special-case check for directory needed to make termcap
          text files load as if they were databases (cf: 20110924).
        + modify tic's resolution/collision checking to attempt to remove the
          conflicting alias from the second entry in the pair, which is
          normally following in the source file.  Also improved the warning
          message to make it simpler to see which alias is the problem.
        + improve performance of the database iterator by caching search-list.

20110925
        + add a missing "else" in changes to _nc_read_tic_entry().

20110924
        + modify _nc_read_tic_entry() so that hashed-database is checked before
          filesystem.
        + updated CF_CURSES_LIBS check in test/configure script.
        + modify configure script and makefiles to split TIC_ARGS and
          TINFO_ARGS into pieces corresponding to LDFLAGS and LIBS variables,
          to help separate searches for tic- and tinfo-libraries (patch by Nick
          Alcock aka "Nix").
        + build-fix for lib_mouse.c changes (cf: 20110917).

20110917
        + fix compiler warning for clang 2.9
        + improve merging of mouse events (integrated patch by Damien
          Guibouret).
        + correct mask-check used in lib_mouse for wheel mouse buttons 4/5
          (patch by Damien Guibouret).

20110910
        + modify misc/gen_edit.sh to select a "linux" entry which works with
          the current kernel rather than assuming it is always "linux3.0"
          (cf: 20110716).
        + revert a change to getmouse() which had the undesirable side-effect
          of suppressing button-release events (report by Damien Guibouret,
          cf: 20100102).
        + add xterm+kbs fragment from xterm #272 -TD
        + add configure option --with-pkg-config-libdir to provide control over
          the actual directory into which pc-files are installed, do not use
          the pkg-config environment variables (discussion with Frederic L W
          Meunier).
        + add link to mailing-list archive in announce.html.in, as done in
          FAQ (prompted by question by Andrius Bentkus).
        + improve manpage install by adjusting the "#include" examples to
          show the ncurses-subdirectory used when --disable-overwrite option
          is used.
        + install an alias for "curses" to the ncurses manpage, tied to the
          --with-curses-h configure option (suggested by Reuben Thomas).

20110903
        + propagate error-returns from wresize, i.e., the internal
          increase_size and decrease_size functions through resize_term (report
          by Tim van der Molen, cf:  20020713).
        + fix typo in tset manpage (patch by Sven Joachim).

20110820
        + add a check to ensure that termcap files which might have "^?" do
          not use the terminfo interpretation as "\177".
        + minor cleanup of X-terminal emulator section of terminfo.src -TD
        + add terminator entry -TD
        + add simpleterm entry -TD
        + improve wattr_get macros by ensuring that if the window pointer is
          null, then the attribute and color values returned will be zero
          (cf: 20110528).

20110813
        + add substitution for $RPATH_LIST to misc/ncurses-config.in
        + improve performance of tic with hashed-database by caching the
          database connection, using atexit() to cleanup.
        + modify treatment of 2-character aliases at the beginning of termcap
          entries so they are not counted in use-resolution, since these are
          guaranteed to be unique.  Also ignore these aliases when reporting
          the primary name of the entry (cf: 20040501)
        + double-check gn (generic) flag in terminal descriptions to
          accommodate old/buggy termcap databases which misused that feature.
        + minor fixes to _nc_tgetent(), ensure buffer is initialized even on
          error-return.

20110807
        + improve rpath fix from 20110730 by ensuring that the new $RPATH_LIST
          variable is defined in the makefiles which use it.
        + build-fix for DragonFlyBSD's pkgsrc in test/configure script.
        + build-fixes for NetBSD 5.1 with termcap support enabled.
        + corrected k9 in dg460-ansi, add other features based on manuals -TD
        + improve trimming of whitespace at the end of terminfo/termcap output
          from tic/infocmp.
        + when writing termcap source, ensure that colons in the description
          field are translated to a non-delimiter, i.e., "=".
        + add "-0" option to tic/infocmp, to make the termcap/terminfo source
          use a single line.
        + add a null-pointer check when handling the $CC variable.

20110730
        + modify configure script and makefiles in c++ and progs to allow the
          directory used for rpath option to be overridden, e.g., to work
          around updates to the variables used by tic during an install.
        + add -K option to tic/infocmp, to provide stricter BSD-compatibility
          for termcap output.
        + add _nc_strict_bsd variable in tic library which controls the
          "strict" BSD termcap compatibility from 20110723, plus these
          features:
          + allow escapes such as "\8" and "\9" when reading termcap
          + disallow "\a", "\e", "\l", "\s" and "\:" escapes when reading
            termcap files, passing through "a", "e", etc.
          + expand "\:" as "\072" on output.
        + modify _nc_get_token() to reset the token's string value in case
          there is a string-typed token lacking the "=" marker.
        + fix a few memory leaks in _nc_tgetent.
        + fix a few places where reading from a termcap file could refer to
          freed memory.
        + add an overflow check when converting terminfo/termcap numeric
          values, since terminfo stores those in a short, and they must be
          positive.
        + correct internal variables used for translating to termcap "%>"
          feature, and translating from termcap %B to terminfo, needed by
          tctest (cf: 19991211).
        + amend a minor fix to acsc when loading a termcap file to separate it
          from warnings needed for tic (cf: 20040710)
        + modify logic in _nc_read_entry() and _nc_read_tic_entry() to allow
          a termcap file to be handled via TERMINFO_DIRS.
        + modify _nc_infotocap() to include non-mandatory padding when
          translating to termcap.
        + modify _nc_read_termcap_entry(), passing a flag in the case where
          getcap is used, to reduce interactive warning messages.

20110723
        + add a check in start_color() to limit color-pairs to 256 when
          extended colors are not supported (patch by David Benjamin).
        + modify setcchar to omit no-longer-needed OR'ing of color pair in
          the SetAttr() macro (patch by David Benjamin).
        + add kich1 to sun terminfo entry (Yuri Pankov)
        + use bold rather than reverse for smso in sun-color terminfo entry
          (Yuri Pankov).
        + improve generation of termcap using tic/infocmp -C option, e.g.,
          to correspond with 4.2BSD (prompted by discussion with Yuri Pankov
          regarding Schilling's test program):
          + translate %02 and %03 to %2 and %3 respectively.
          + suppress string capabilities which use %s, not supported by tgoto
          + use \040 rather than \s
          + expand null characters as \200 rather than \0
        + modify configure script to support shared libraries for DragonFlyBSD.

20110716
        + replace an assert() in _nc_Free_Argument() with a regular null
          pointer check (report/analysis by Franjo Ivancic).
        + modify configure --enable-pc-files option to take into account the
          PKG_CONFIG_PATH variable (report by Frederic L W Meunier).
        + add/use xterm+tmux chunk from xterm #271 -TD
        + resync xterm-new entry from xterm #271 -TD
        + add E3 extended capability to linux-basic (Miroslav Lichvar)
        + add linux2.2, linux2.6, linux3.0 entries to give context for E3 -TD
        + add SI/SO change to linux2.6 entry (Debian #515609) -TD
        + fix inconsistent tabset path in pcmw (Todd C. Miller).
        + remove a backslash which continued comment, obscuring altos3
          definition with OpenBSD toolset (Nicholas Marriott).

20110702
        + add workaround from xterm #271 changes to ensure that compiler flags
          are not used in the $CC variable.
        + improve support for shared libraries, tested with AIX 5.3, 6.1 and
          7.1 with both gcc 4.2.4 and cc.
        + modify configure checks for AIX to include release 7.x
        + add loader flags/libraries to libtool options so that dynamic loading
          works properly, adapted from ncurses-5.7-ldflags-with-libtool.patch
          at gentoo prefix repository (patch by Michael Haubenwallner).

20110626
        + move include of nc_termios.h out of term_entry.h, since the latter
          is installed, e.g., for tack while the former is not (report by
          Sven Joachim).

20110625
        + improve cleanup() function in lib_tstp.c, using _exit() rather than
          exit() and checking for SIGTERM rather than SIGQUIT (prompted by
          comments forwarded by Nicholas Marriott).
        + reduce name pollution from term.h, moving fallback #define's for
          tcgetattr(), etc., to new private header nc_termios.h (report by
          Sergio NNX).
        + two minor fixes for tracing (patch by Vassili Courzakis).
        + improve trace initialization by starting it in use_env() and
          ripoffline().
        + review old email, add details for some changelog entries.

20110611
        + update minix entry to minix 3.2 (Thomas Cort).
        + fix a strict compiler warning in change to wattr_get (cf: 20110528).

20110604
        + fixes for MirBSD port:
          + set default prefix to /usr.
          + add support for shared libraries in configure script.
          + use S_ISREG and S_ISDIR consistently, with fallback definitions.
        + add a few more checks based on ncurses/link_test.
        + modify MKlib_gen.sh to handle sp-funcs renaming of NCURSES_OUTC type.

20110528
        + add case to CF_SHARED_OPTS for Interix (patch by Markus Duft).
        + used ncurses/link_test to check for behavior when the terminal has
          not been initialized and when an application passes null pointers
          to the library.  Added checks to cover this (prompted by Redhat
          #707344).
        + modify MKlib_gen.sh to make its main() function call each function
          with zero parameters, to help find inconsistent checking for null
          pointers, etc.

20110521
        + fix warnings from clang 2.7 "--analyze"

20110514
        + compiler-warning fixes in panel and progs.
        + modify CF_PKG_CONFIG macro, from changes to tin -TD
        + modify CF_CURSES_FUNCS configure macro, used in test directory
          configure script:
          + work around (non-optimizer) bug in gcc 4.2.1 which caused
            test-expression to be omitted from executable.
          + force the linker to see a link-time expression of a symbol, to
            help work around weak-symbol issues.

20110507
        + update discussion of MKfallback.sh script in INSTALL; normally the
          script is used automatically via the configured makefiles.  However
          there are still occasions when it might be used directly by packagers
          (report by Gunter Schaffler).
        + modify misc/ncurses-config.in to omit the "-L" option from the
          "--libs" output if the library directory is /usr/lib.
        + change order of tests for curses.h versus ncurses.h headers in the
          configure scripts for Ada95 and test-directories, to look for
          ncurses.h, from fixes to tin -TD
        + modify ncurses/tinfo/access.c to account for Tandem's root uid
          (report by Joachim Schmitz).

20110430
        + modify rules in Ada95/src/Makefile.in to ensure that the PIC option
          is not used when building a static library (report by Nicolas
          Boulenguez):
        + Ada95 build-fix for big-endian architectures such as sparc.  This
          undoes one of the fixes from 20110319, which added an "Unused" member
          to representation clauses, replacing that with pragmas to suppress
          warnings about unused bits (patch by Nicolas Boulenguez).

20110423
        + add check in test/configure for use_window, use_screen.
        + add configure-checks for getopt's variables, which may be declared
          as different types on some Unix systems.
        + add check in test/configure for some legacy curses types of the
          function pointer passed to tputs().
        + modify init_pair() to accept -1's for color value after
          assume_default_colors() has been called (Debian #337095).
        + modify test/background.c, adding commmand-line options to demonstrate
          assume_default_colors() and use_default_colors().

20110416
        + modify configure script/source-code to only define _POSIX_SOURCE if
          the checks for sigaction and/or termios fail, and if _POSIX_C_SOURCE
          and _XOPEN_SOURCE are undefined (report by Valentin Ochs).
        + update config.guess, config.sub

20110409
        + fixes to build c++ binding with clang 3.0 (patch by Alexander
          Kolesen).
        + add check for unctrl.h in test/configure, to work around breakage in
          some ncurses packages.
        + add "--disable-widec" option to test/configure script.
        + add "--with-curses-colr" and "--with-curses-5lib" options to the
          test/configure script to address testing with very old machines.

20110404 5.9 release for upload to ftp.gnu.org

20110402
        + various build-fixes for the rpm/dpkg scripts.
        + add "--enable-rpath-link" option to Ada95/configure, to allow
          packages to suppress the rpath feature which is normally used for
          the in-tree build of sample programs.
        + corrected definition of libdir variable in Ada95/src/Makefile.in,
          needed for rpm script.
        + add "--with-shared" option to Ada95/configure script, to allow
          making the C-language parts of the binding use appropriate compiler
          options if building a shared library with gnat.

20110329
        > portability fixes for Ada95 binding:
        + add configure check to ensure that SIGINT works with gnat.  This is
          needed for the "rain" sample program.  If SIGINT does not work, omit
          that sample program.
        + correct typo in check of $PKG_CONFIG variable in Ada95/configure
        + add ncurses_compat.c, to supply functions used in the Ada95 binding
          which were added in 5.7 and later.
        + modify sed expression in CF_NCURSES_ADDON to eliminate a dependency
          upon GNU sed.

20110326
        + add special check in Ada95/configure script for ncurses6 reentrant
          code.
        + regen Ada html documentation.
        + build-fix for Ada shared libraries versus the varargs workaround.
        + add rpm and dpkg scripts for Ada95 and test directories, for test
          builds.
        + update test/configure macros CF_CURSES_LIBS, CF_XOPEN_SOURCE and
          CF_X_ATHENA_LIBS.
        + add configure check to determine if gnat's project feature supports
          libraries, i.e., collections of .ali files.
        + make all dereferences in Ada95 samples explicit.
        + fix typo in comment in lib_add_wch.c (patch by Petr Pavlu).
        + add configure check for, ifdef's for math.h which is in a separate
          package on Solaris and potentially not installed (report by Petr
          Pavlu).
        > fixes for Ada95 binding (Nicolas Boulenguez):
        + improve type-checking in Ada95 by eliminating a few warning-suppress
          pragmas.
        + suppress unreferenced warnings.
        + make all dereferences in binding explicit.

20110319
        + regen Ada html documentation.
        + change order of -I options from ncurses*-config script when the
          --disable-overwrite option was used, so that the subdirectory include
          is listed first.
        + modify the make-tar.sh scripts to add a MANIFEST and NEWS file.
        + modify configure script to provide value for HTML_DIR in
          Ada95/gen/Makefile.in, which depends on whether the Ada95 binding is
          distributed separately (report by Nicolas Boulenguez).
        + modify configure script to add "-g" and/or "-O3" to ADAFLAGS if the
          CFLAGS for the build has these options.
        + amend change from 20070324, to not add 1 to the result of getmaxx
          and getmaxy in the Ada binding (report by Nicolas Boulenguez for
          thread in comp.lang.ada).
        + build-fix Ada95/samples for gnat 4.5
        + spelling fixes for Ada95/samples/explain.txt
        > fixes for Ada95 binding (Nicolas Boulenguez):
        + add item in Trace_Attribute_Set corresponding to TRACE_ATTRS.
        + add workaround for binding to set_field_type(), which uses varargs.
          The original binding from 990220 relied on the prevalent
          implementation of varargs which did not support or need va_copy().
        + add dependency on gen/Makefile.in needed for *-panels.ads
        + add Library_Options to library.gpr
        + add Languages to library.gpr, for gprbuild

20110307
        + revert changes to limit-checks from 20110122 (Debian #616711).
        > minor type-cleanup of Ada95 binding (Nicolas Boulenguez):
        + corrected a minor sign error in a field of Low_Level_Field_Type, to
          conform to form.h.
        + replaced C_Int by Curses_Bool as return type for some callbacks, see
          fieldtype(3FORM).
        + modify samples/sample-explain.adb to provide explicit message when
          explain.txt is not found.

20110305
        + improve makefiles for Ada95 tree (patch by Nicolas Boulenguez).
        + fix an off-by-one error in _nc_slk_initialize() from 20100605 fixes
          for compiler warnings (report by Nicolas Boulenguez).
        + modify Ada95/gen/gen.c to declare unused bits in generated layouts,
          needed to compile when chtype is 64-bits using gnat 4.4.5

          a new install of hashed database.
        + fix typo in Ada95/mk-1st.awk which causes error with original awk.

20110220
        + configure script rpath fixes from xterm #269.

20110205
        + add xterm-utf8 entry as a demo of the U8 feature -TD
        + add U8 feature to denote entries for terminal emulators which do not
          support VT100 SI/SO when processing UTF-8 encoding -TD
        + improve the NCURSES_NO_UTF8_ACS feature by adding a check for an
          extended terminfo capability U8 (prompted by mailing list
          discussion).

20101128
        + modify test/configure and test/Makefile.in to handle this special
          case of building within a build-tree (Debian #34182):
                mkdir -p build && cd build && ../test/configure && make

20101127
        + miscellaneous build-fixes for Ada95 and test-directories when built

        + fix typo in rmso for tek4106 entry -Goran Weinholt

20101120
        + improve checks in test/configure for X libraries, from xterm #267
          changes.
        + modify test/configure to allow it to use the build-tree's libraries
          e.g., when using that to configure the test-programs without the
          rpath feature (request by Sven Joachim).
        + repurpose "gnome" terminfo entries as "vte", retaining "gnome" items
          for compatibility, but generally deprecating those since the VTE
          library is what actually defines the behavior of "gnome", etc.,
          since 2003 -TD

20101113
        + compiler warning fixes for test programs.
        + various build-fixes for test-programs with pdcurses.

          more closely match the non-thread naming (report by Werner Fink).
        + modify configure check for tic program, used for fallbacks, to a
          warning if not found.  This makes it simpler to use additional
          scripts to bootstrap the fallbacks code using tic from the build
          tree (report by Werner Fink).
        + fix several places in configure script using ${variable-value} form.

          inconsistent printer-controls.
        + fill in no-parameter forms of cursor-movement where a parameterized
          form is available -TD
        + fill in missing cursor controls where the form of the controls is
          ANSI -TD
        + fix inconsistent punctuation in form_variables manpage (patch by
          Sven Joachim).
        + add parameterized cursor-controls to linux-basic (report by Dae) -TD

        + use POSIX locale in mk-dlls.sh.in rather than en_US (report by Sven
          Joachim).
        + add a check in mk-dlls.sh.in to obtain the size of a pointer to
          distinguish between 32-bit and 64-bit hosts.  The result is stored
          in mingw_arch

20100925
        + add "XT" capability to entries for terminals that support both
          xterm-style mouse- and title-controls, for "screen" which
          special-cases TERM beginning with "xterm" or "rxvt" -TD
        > patch by Juergen Pfeifer:
        + use 64-Bit MinGW toolchain (recommended package from TDM, see
          README.MinGW).
        + support pthreads when using the TDM MinGW toolchain

20100918
        + regenerated html manpages.
        + minor fixes for symlinks to curs_legacy.3x and curs_slk.3x manpages.

        + add configure check for pthread_kill(), needed for some old
          platforms.

        + modify nsterm, xnuppc and tek4115 to make sgr/sgr0 consistent -TD
        + add check in terminfo source-reader to provide more informative
          message when someone attempts to run tic on a compiled terminal
          description (prompted by Debian #593920).
        + note in infotocap and captoinfo manpages that they read terminal
          descriptions from text-files (Debian #593920).
        + improve acsc string for vt52, show arrow keys (patch by Benjamin
          Sittler).

20100814
        + document in manpages that "mv" functions first use wmove() to check
          the window pointer and whether the position lies within the window
          (suggested by Poul-Henning Kamp).
        + fixes to curs_color.3x, curs_kernel.3x and wresize.3x manpages (patch
          by Tim van der Molen).
        + modify configure script to transform library names for tic- and
          tinfo-libraries so that those build properly with Mac OS X shared
          library configuration.
        + modify configure script to ensure that it removes conftest.dSYM
          directory leftover on checks with Mac OS X.

          is called (patch by Roumen Petrov).
        + document tabs "-0" and "-8" options in manpage.
        + fix Debian "lintian" issues with manpages reported in

        + improve use of symbolic links in makefiles by using "-f" option if
          it is supported, to eliminate temporary removal of the target
          (prompted by http://www.t2-project.org/packages/ncurses.html)
        + minor improvement to test/ncurses.c, reset color pairs in 'd' test
          after exit from 'm' main-menu command.

          + add/use configure check to turn on project rules for Ada95/src.
        + revert the vfork change from 20100130, since it does not work.

20100626
        + continue integrating changes to use gnatmake project files in Ada95
          + old gnatmake (3.15) does not produce libraries using project-file;
            work around by adding script to generate alternate makefile.

20100619
        + continue integrating changes to use gnatmake project files in Ada95
          + add configure --with-ada-sharedlib option, for the test_make rule.
          + move Ada95-related logic into aclocal.m4, since additional checks
            will be needed to distinguish old/new implementations of gnat.

20100612
        + start integrating changes to use gnatmake project files in Ada95 tree
          + add test_make / test_clean / test_install rules in Ada95/src
          + change install-path for adainclude directory to /usr/share/ada (was
            /usr/lib/ada).
        + update Ada95/configure.
        + add mlterm+256color entry, for mlterm 3.0.0 -TD
        + modify test/configure to use macros to ensure consistent order
          of updating LIBS variable.

20100605
        + change search order of options for Solaris in CF_SHARED_OPTS, to
          work with 64-bit compiles.
        + correct quoting of assignment in CF_SHARED_OPTS case for aix
          (cf: 20081227)

20100529
        + regenerated html documentation.
        + modify test/configure to support pkg-config for checking X libraries
          used by PDCurses.
        + add/use configure macro CF_ADD_LIB to force consistency of
          assignments to $LIBS, etc.
        + fix configure script for combining --with-pthread
          and --enable-weak-symbols options.

20100522
        + correct cross-compiling configure check for CF_MKSTEMP macro, by
          adding a check cache variable set by AC_CHECK_FUNC (report by
          Pierre Labastie).
        + simplify include-dependencies of make_hash and make_keys, to reduce
          the need for setting BUILD_CPPFLAGS in cross-compiling when the
          build- and target-machines differ.
        + repair broken-linker configuration by restoring a definition of SP
          variable to curses.priv.h, and adjusting for cases where sp-funcs
          are used.
        + improve configure macro CF_AR_FLAGS, allowing ARFLAGS environment
          variable to override (prompted by report by Pablo Cazallas).

20100515
        + add configure option --enable-pthreads-eintr to control whether the
          new EINTR feature is enabled.
        + modify logic in pthread configuration to allow EINTR to interrupt
          a read operation in wgetch() (Novell #540571, patch by Werner Fink).
        + drop mkdirs.sh, use "mkdir -p".
        + add configure option --disable-libtool-version, to use the
          "-version-number" feature which was added in libtool 1.5 (report by
          Peter Haering).  The default value for the option uses the newer
          feature, which makes libraries generated using libtool compatible
          with the standard builds of ncurses.
        + updated test/configure to match configure script macros.
        + fixes for configure script from lynx changes:
          + improve CF_FIND_LINKAGE logic for the case where a function is
            found in predefined libraries.
          + revert part of change to CF_HEADER (cf: 20100424)

20100501
        + correct limit-check in wredrawln, accounting for begy/begx values
          (patch by David Benjamin).
        + fix most compiler warnings from clang.
        + amend build-fix for OpenSolaris, to ensure that a system header is
          included in curses.h before testing feature symbols, since they
          may be defined by that route.

20100424
        + fix some strict compiler warnings in ncurses library.
        + modify configure macro CF_HEADER_PATH to not look for variations in
          the predefined include directories.
        + improve configure macros CF_GCC_VERSION and CF_GCC_WARNINGS to work
          with gcc 4.x's c89 alias, which gives warning messages for cases
          where older versions would produce an error.

20100417
        + modify _nc_capcmp() to work with cancelled strings.
        + correct translation of "^" in _nc_infotocap(), used to transform
          terminfo to termcap strings
        + add configure --disable-rpath-hack, to allow disabling the feature
          which adds rpath options for libraries in unusual places.
        + improve CF_RPATH_HACK_2 by checking if the rpath option for a given
          directory was already added.
        + improve CF_RPATH_HACK_2 by using ldd to provide a standard list of
          directories (which will be ignored).

20100410
        + improve win_driver.c handling of mouse:
          + discard motion events
          + avoid calling _nc_timed_wait when there is a mouse event
          + handle 4th and "rightmost" buttons.
        + quote substitutions in CF_RPATH_HACK_2 configure macro, needed for
          cases where there are embedded blanks in the rpath option.

20100403
        + add configure check for exctags vs ctags, to work around pkgsrc.
        + simplify logic in _nc_get_screensize() to make it easier to see how
          environment variables may override system- and terminfo-values
          (prompted by discussion with Igor Bujna).
        + make debug-traces for COLOR_PAIR and PAIR_NUMBER less verbose.
        + improve handling of color-pairs embedded in attributes for the
          extended-colors configuration.
        + modify MKlib_gen.sh to build link_test with sp-funcs.
        + build-fixes for OpenSolaris aka Solaris 11, for wide-character
          configuration as well as for rpath feature in *-config scripts.

20100327
        + refactor CF_SHARED_OPTS configure macro, making CF_RPATH_HACK more
          reusable.
        + improve configure CF_REGEX, similar fixes.
        + improve configure CF_FIND_LINKAGE, adding add check between system
          (default) and explicit paths, where we can find the entrypoint in the
          given library.
        + add check if Gpm_Open() returns a -2, e.g., for "xterm".  This is
          normally suppressed but can be overridden using $NCURSES_GPM_TERMS.
          Ensure that Gpm_Close() is called in this case.

20100320
        + rename atari and st52 terminfo entries to atari-old, st52-old, use
          newer entries from FreeMiNT by Guido Flohr (from patch/report by Alan
          Hourihane).

20100313
        + modify install-rule for manpages so that *-config manpages will
          install when building with --srcdir (report by Sven Joachim).
        + modify CF_DISABLE_LEAKS configure macro so that the --enable-leaks
          option is not the same as --disable-leaks (GenToo #305889).
        + modify #define's for build-compiler to suppress cchar_t symbol from
          compile of make_hash and make_keys, improving cross-compilation of
          ncursesw (report by Bernhard Rosenkraenzer).
        + modify CF_MAN_PAGES configure macro to replace all occurrences of
          TPUT in tput.1's manpage (Debian #573597, report/analysis by Anders
          Kaseorg).

20100306
        + generate manpages for the *-config scripts, adapted from help2man
          (suggested by Sven Joachim).
        + use va_copy() in _nc_printf_string() to avoid conflicting use of
          va_list value in _nc_printf_length() (report by Wim Lewis).

20100227
        + add Ada95/configure script, to use in tar-file created by
          Ada95/make-tar.sh
        + fix typo in wresize.3x (patch by Tim van der Molen).
        + modify screen-bce.XXX entries to exclude ech, since screen's color
          model does not clear with color for that feature -TD

20100220
        + add make-tar.sh scripts to Ada95 and test subdirectories to help with
          making those separately distributable.
        + build-fix for static libraries without dlsym (Debian #556378).
        + fix a syntax error in man/form_field_opts.3x (patch by Ingo
          Schwarze).

20100213
        + add several screen-bce.XXX entries -TD

20100206
        + update mrxvt terminfo entry -TD
        + modify win_driver.c to support mouse single-clicks.
        + correct name for termlib in ncurses*-config, e.g., if it is renamed
          to provide a single file for ncurses/ncursesw libraries (patch by
          Miroslav Lichvar).

20100130
        + use vfork in test/ditto.c if available (request by Mike Frysinger).
        + miscellaneous cleanup of manpages.
        + fix typo in curs_bkgd.3x (patch by Tim van der Molen).
        + build-fix for --srcdir (patch by Miroslav Lichvar).

20100123
        + for term-driver configuration, ensure that the driver pointer is
          initialized in setupterm so that terminfo/termcap programs work.
        + amend fix for Debian #542031 to ensure that wattrset() returns only
          OK or ERR, rather than the attribute value (report by Miroslav
          Lichvar).
        + reorder WINDOWLIST to put WINDOW data after SCREEN pointer, making
          _nc_screen_of() compatible between normal/wide libraries again (patch
          by Miroslav Lichvar)
        + review/fix include-dependencies in modules files (report by Miroslav
          Lichvar).

20100116
        + modify win_driver.c to initialize acs_map for win32 console, so
          that line-drawing works.
        + modify win_driver.c to initialize TERMINAL struct so that programs
          such as test/lrtest.c and test/ncurses.c which test string
          capabilities can run.
        + modify term-driver modules to eliminate forward-reference
          declarations.

20100109
        + modify configure macro CF_XOPEN_SOURCE, etc., to use CF_ADD_CFLAGS
          consistently to add new -D's while removing duplicates.
        + modify a few configure macros to consistently put new options
          before older in the list.
        + add tiparm(), based on review of X/Open Curses Issue 7.
        + minor documentation cleanup.
        + update config.guess, config.sub from
                http://savannah.gnu.org/projects/config
          (caveat - its maintainer put 2010 copyright date on files dated 2009)

20100102
        + minor improvement to tic's checking of similar SGR's to allow for the
          most common case of SGR 0.
        + modify getmouse() to act as its documentation implied, returning on
          each call the preceding event until none are left.  When no more
          events remain, it will return ERR.

20091227
        + change order of lookup in progs/tput.c, looking for terminfo data
          first.  This fixes a confusion between termcap "sg" and terminfo
          "sgr" or "sgr0", originally from 990123 changes, but exposed by
          20091114 fixes for hashing.  With this change, only "dl" and "ed" are
          ambiguous (Mandriva #56272).

20091226
        + add bterm terminfo entry, based on bogl 0.1.18 -TD
        + minor fix to rxvt+pcfkeys terminfo entry -TD
        + build-fixes for Ada95 tree for gnat 4.4 "style".

20091219
        + remove old check in mvderwin() which prevented moving a derived
          window whose origin happened to coincide with its parent's origin
          (report by Katarina Machalkova).
        + improve test/ncurses.c to put mouse droppings in the proper window.
        + update minix terminfo entry -TD
        + add bw (auto-left-margin) to nsterm* entries (Benjamin Sittler)

20091212
        + correct transfer of multicolumn characters in multirow
          field_buffer(), which stopped at the end of the first row due to
          filling of unused entries in a cchar_t array with nulls.
        + updated nsterm* entries (Benjamin Sittler, Emanuele Giaquinta)
        + modify _nc_viscbuf2() and _tracecchar_t2() to show wide-character
          nulls.
        + use strdup() in set_menu_mark(), restore .marklen struct member on
          failure.
        + eliminate clause 3 from the UCB copyrights in read_termcap.c and
          tset.c per
                ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change
          (patch by Nicholas Marriott).
        + replace a malloc in tic.c with strdup, checking for failure (patch by
          Nicholas Marriott).
        + update config.guess, config.sub from
                http://savannah.gnu.org/projects/config

20091205
        + correct layout of working window used to extract data in
          wide-character configured by set_field_buffer (patch by Rafael
          Garrido Fernandez)
        + improve some limit-checks related to filename length in reading and
          writing terminfo entries.
        + ensure that filename is always filled in when attempting to read
          a terminfo entry, so that infocmp can report the filename (patch
          by Nicholas Marriott).

20091128
        + modify mk-1st.awk to allow tinfo library to be built when term-driver
          is enabled.
        + add error-check to configure script to ensure that sp-funcs is
          enabled if term-driver is, since some internal interfaces rely upon
          this.

20091121
        + fix case where progs/tput is used while sp-funcs is configure; this
          requires save/restore of out-character function from _nc_prescreen
          rather than the SCREEN structure (report by Charles Wilson).
        + fix typo in man/curs_trace.3x which caused incorrect symbolic links
        + improved configure macros CF_GCC_ATTRIBUTES, CF_PROG_LINT.

20091114
        + updated man/curs_trace.3x
        + limit hashing for termcap-names to 2-characters (Ubuntu #481740).
        + change a variable name in lib_newwin.c to make it clearer which
          value is being freed on error (patch by Nicholas Marriott).

20091107
        + improve test/ncurses.c color-cycling test by reusing attribute-
          and color-cycling logic from the video-attributes screen.
        + add ifdef'd with NCURSES_INTEROP_FUNCS experimental bindings in form
          library which help make it compatible with interop applications
          (patch by Juergen Pfeifer).
        + add configure option --enable-interop, for integrating changes
          for generic/interop support to form-library by Juergen Pfeifer

20091031
        + modify use of $CC environment variable which is defined by X/Open
          as a curses feature, to ignore it if it is not a single character
          (prompted by discussion with Benjamin C W Sittler).
        + add START_TRACE in slk_init
        + fix a regression in _nc_ripoffline which made test/ncurses.c not show
          soft-keys, broken in 20090927 merging.
        + change initialization of "hidden" flag for soft-keys from true to
          false, broken in 20090704 merging (Ubuntu #464274).
        + update nsterm entries (patch by Benjamin C W Sittler, prompted by
          discussion with Fabian Groffen in GenToo #206201).
        + add test/xterm-256color.dat

20091024
        + quiet some pedantic gcc warnings.
        + modify _nc_wgetch() to check for a -1 in the fifo, e.g., after a
          SIGWINCH, and discard that value, to avoid confusing application
          (patch by Eygene Ryabinkin, FreeBSD #136223).

20091017
        + modify handling of $PKG_CONFIG_LIBDIR to use only the first item in
          a possibly colon-separated list (Debian #550716).

20091010
        + supply a null-terminator to buffer in _nc_viswibuf().
        + fix a sign-extension bug in unget_wch() (report by Mike Gran).
        + minor fixes to error-returns in default function for tputs, as well
          as in lib_screen.c

20091003
        + add WACS_xxx definitions to wide-character configuration for thick-
          and double-lines (discussion with Slava Zanko).
        + remove unnecessary kcan assignment to ^C from putty (Sven Joachim)
        + add ccc and initc capabilities to xterm-16color -TD
        > patch by Benjamin C W Sittler:
        + add linux-16color
        + correct initc capability of linux-c-nc end-of-range
        + similar change for dg+ccc and dgunix+ccc

20090927
        + move leak-checking for comp_captab.c into _nc_leaks_tinfo() since
          that module since 20090711 is in libtinfo.
        + add configure option --enable-term-driver, to allow compiling with
          terminal-driver.  That is used in MinGW port, and (being somewhat
          more complicated) is an experimental alternative to the conventional
          termlib internals.  Currently, it requires the sp-funcs feature to
          be enabled.
        + completed integrating "sp-funcs" by Juergen Pfeifer in ncurses
          library (some work remains for forms library).

20090919
        + document return code from define_key (report by Mike Gran).
        + make some symbolic links in the terminfo directory-tree shorter
          (patch by Daniel Jacobowitz, forwarded by Sven Joachim).).
        + fix some groff warnings in terminfo.5, etc., from recent Debian
          changes.
        + change ncv and op capabilities in sun-color terminfo entry to match
          Sun's entry for this (report by Laszlo Peter).
        + improve interix smso terminfo capability by using reverse rather than
          bold (report by Kristof Zelechovski).

20090912
        + add some test programs (and make these use the same special keys
          by sharing linedata.h functions):
          test/test_addstr.c
          test/test_addwstr.c
          test/test_addchstr.c
          test/test_add_wchstr.c
        + correct internal _nc_insert_ch() to use _nc_insert_wch() when
          inserting wide characters, since the wins_wch() function that it used
          did not update the cursor position (report by Ciprian Craciun).

20090906
        + fix typo s/is_timeout/is_notimeout/ which made "man is_notimeout" not
          work.
        + add null-pointer checks to other opaque-functions.
        + add is_pad() and is_subwin() functions for opaque access to WINDOW
          (discussion with Mark Dickinson).
        + correct merge to lib_newterm.c, which broke when sp-funcs was
          enabled.

20090905
        + build-fix for building outside source-tree (report by Sven Joachim).
        + fix Debian lintian warning for man/tabs.1 by making section number
          agree with file-suffix (report by Sven Joachim).
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090829
        + workaround for bug in g++ 4.1-4.4 warnings for wattrset() macro on
          amd64 (Debian #542031).
        + fix typo in curs_mouse.3x (Debian #429198).

20090822
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090815
        + correct use of terminfo capabilities for initializing soft-keys,
          broken in 20090510 merging.
        + modify wgetch() to ensure it checks SIGWINCH when it gets an error
          in non-blocking mode (patch by Clemens Ladisch).
        + use PATH_SEPARATOR symbol when substituting into run_tic.sh, to
          help with builds on non-Unix platforms such as OS/2 EMX.
        + modify scripting for misc/run_tic.sh to test configure script's
          $cross_compiling variable directly rather than comparing host/build
          compiler names (prompted by comment in GenToo #249363).
        + fix configure script option --with-database, which was coded as an
          enable-type switch.
        + build-fixes for --srcdir (report by Frederic L W Meunier).

20090808
        + separate _nc_find_entry() and _nc_find_type_entry() from
          implementation details of hash function.

20090803
        + add tabs.1 to man/man_db.renames
        + modify lib_addch.c to compensate for removal of wide-character test
          from unctrl() in 20090704 (Debian #539735).

20090801
        + improve discussion in INSTALL for use of system's tic/infocmp for
          cross-compiling and building fallbacks.
        + modify test/demo_termcap.c to correspond better to options in
          test/demo_terminfo.c
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).
        + fix logic for 'V' in test/ncurses.c tests f/F.

20090728

          20090704 changes.
        + modify _nc_find_type_entry() to use hashing.
        + make CCHARW_MAX value configurable, noting that changing this would
          change the size of cchar_t, and would be ABI-incompatible.
        + modify test-programs, e.g,.  test/view.c, to address subtle
          differences between Tru64/Solaris and HPUX/AIX getcchar() return
          values.
        + modify length returned by getcchar() to count the trailing null

        + improve performance of tigetstr, etc., by using hashing code from tic.
        + minor fixes for memory-leak checking.
        + add test/demo_terminfo, for comparison with demo_termcap

20090704
        + remove wide-character checks from unctrl() (patch by Clemens Ladisch).
        + revise wadd_wch() and wecho_wchar() to eliminate dependency on
          unctrl().
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

          MinGW.

20090613
        + move definition for NCURSES_WRAPPED_VAR back to ncurses_dll.h, to
          make includes of term.h without curses.h work (report by "Nix").
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090607
        + fix a regression in lib_tputs.c, from ongoing merges.

20090606
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090530
        + fix an infinite recursion when adding a legacy-coding 8-bit value
          using insch() (report by Clemens Ladisch).
        + free home-terminfo string in del_curterm() (patch by Dan Weber).
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

          SCREEN's copy of the pointer (Debian #528411).
        + add a cast to wattrset macro to avoid compiler warning when comparing
          its result against ERR (adapted from patch by Matt Kraii, Debian
          #528374).

20090510
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090502
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).
        + add vwmterm terminfo entry (patch by Bryan Christ).

20090425
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090419

          part of the form library.

20090404
        + suppress configure check for static/dynamic linker flags for gcc on
          Darwin (report by Nelson Beebe).

20090328
        + extend ansi.sys pfkey capability from kf1-kf10 to kf1-kf48, moving
          function key definitions from emx-base for consistency -TD
        + correct missing final 'p' in pfkey capability of ansi.sys-old (report
          by Kalle Olavi Niemitalo).
        + improve test/ncurses.c 'F' test, show combining characters in color.
        + quiet a false report by cppcheck in c++/cursesw.cc by eliminating
          a temporary variable.
        + use _nc_doalloc() rather than realloc() in a few places in ncurses
          library to avoid leak in out-of-memory condition (reports by William
          Egert and Martin Ettl based on cppcheck tool).
        + add --with-ncurses-wrap-prefix option to test/configure (discussion
          with Charles Wilson).
        + use ncurses*-config scripts if available for test/configure.
        + update test/aclocal.m4 and test/configure
        > patches by Charles Wilson:
        + modify CF_WITH_LIBTOOL configure check to allow unreleased libtool
          version numbers (e.g.  which include alphabetic chars, as well as
          digits, after the final '.').
        + improve use of -no-undefined option for libtool by setting an
          intermediate variable LT_UNDEF in the configure script, and then
          using that in the libtool link-commands.
        + fix an missing use of NCURSES_PUBLIC_VAR() in tinfo/MKcodes.awk
          from 20090321 changes.
        + improve mk-1st.awk script by writing separate cases for the
          LIBTOOL_LINK command, depending on which library (ncurses, ticlib,
          termlib) is to be linked.
        + modify configure.in to allow broken-linker configurations, not just
          enable-reentrant, to set public wrap prefix.

20090321
        + add TICS_LIST and SHLIB_LIST to allow libtool 2.2.6 on Cygwin to
          build with tic and term libraries (patch by Charles Wilson).
        + add -no-undefined option to libtool for Cygwin, MinGW, U/Win and AIX
          (report by Charles Wilson).
        + fix definition for c++/Makefile.in's SHLIB_LIST, which did not list
          the form, menu or panel libraries (patch by Charles Wilson).
        + add configure option --with-wrap-prefix to allow setting the prefix
          for functions used to wrap global variables to something other than
          "_nc_" (discussion with Charles Wilson).

20090314
        + modify scripts to generate ncurses*-config and pc-files to add
          dependency for tinfo library (patch by Charles Wilson).
        + improve comparison of program-names when checking for linked flavors
          such as "reset" by ignoring the executable suffix (reports by Charles
          Wilson, Samuel Thibault and Cedric Bretaudeau on Cygwin mailing
          list).
        + suppress configure check for static/dynamic linker flags for gcc on
          Solaris 10, since gcc is confused by absence of static libc, and
          does not switch back to dynamic mode before finishing the libraries
          (reports by Joel Bertrand, Alan Pae).
        + minor fixes to Intel compiler warning checks in configure script.
        + modify _nc_leaks_tinfo() so leak-checking in test/railroad.c works.
        + modify set_curterm() to make broken-linker configuration work with
          changes from 20090228 (report by Charles Wilson).

20090228
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).
        + modify declaration of cur_term when broken-linker is used, but
          enable-reentrant is not, to match pre-5.7 (report by Charles Wilson).

20090221
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090214
        + add configure script --enable-sp-funcs to enable the new set of
          extended functions.
        + start integrating patches by Juergen Pfeifer:
          + add extended functions which specify the SCREEN pointer for several
            curses functions which use the global SP (these are incomplete;
            some internals work is needed to complete these).
          + add special cases to configure script for MinGW port.

20090207
        + update several configure macros from lynx changes
          + append (not prepend) to CFLAGS/CPPFLAGS
          + change variable from PATHSEP to PATH_SEPARATOR
        + improve install-rules for pc-files (patch by Miroslav Lichvar).
          + make it work with $DESTDIR
          + create the pkg-config library directory if needed.

20090124
        + modify init_pair() to allow caller to create extra color pairs beyond
          the color_pairs limit, which use default colors (request by Emanuele
          Giaquinta).
        + add misc/terminfo.tmp and misc/*.pc to "sources" rule.
        + fix typo "==" where "=" is needed in ncurses-config.in and
          gen-pkgconfig.in files (Debian #512161).

20090117
        + add -shared option to MK_SHARED_LIB when -Bsharable is used, for
          *BSD's, without which "main" might be one of the shared library's
          dependencies (report/analysis by Ken Dickey).
        + modify waddch_literal(), updating line-pointer after a multicolumn
          character is found to not fit on the current row, and wrapping is
          done.  Since the line-pointer was not updated, the wrapped
          multicolumn character was written to the beginning of the current row
          (cf: 20041023, reported by "Nick" regarding problem with ncmpc
          http://musicpd.org/mantis/bug_view_page.php?bug_id=1930).

20090110
        + add screen.Eterm terminfo entry (GenToo #124887) -TD
        + modify adacurses-config to look for ".ali" files in the adalib
          directory.
        + correct install for Ada95, which omitted libAdaCurses.a used in
          adacurses-config
        + change install for adacurses-config to provide additional flavors
          such as adacursesw-config, for ncursesw (GenToo #167849).

20090105
        + remove undeveloped feature in ncurses-config.in for setting
          prefix variable.
        + recent change to ncurses-config.in did not take into account the
          --disable-overwrite option, which sets $includedir to the
          subdirectory and using just that for a -I option does not work - fix
          (report by Frederic L W Meunier).

20090104
        + modify gen-pkgconfig.in to eliminate a dependency on rpath when
          deciding whether to add $LIBS to --libs output; that should be shown
          for the ncurses and tinfo libraries without taking rpath into
          account.
        + fix an overlooked change from $AR_OPTS to $ARFLAGS in mk-1st.awk,
          used in static libraries (report by Marty Jack).

20090103
        + add a configure-time check to pick a suitable value for
          CC_SHARED_OPTS for Solaris (report by Dagobert Michelsen).
        + add configure --with-pkg-config and --enable-pc-files options, along
          with misc/gen-pkgconfig.in which can be used to generate ".pc" files
          for pkg-config (request by Jan Engelhardt).
        + use $includedir symbol in misc/ncurses-config.in, add --includedir
          option.
        + change makefiles to use $ARFLAGS rather than $AR_OPTS, provide a
          configure check to detect whether a "-" is needed before "ar"
          options.
        + update config.guess, config.sub from
                http://savannah.gnu.org/projects/config

20081227
        + modify mk-1st.awk to work with extra categories for tinfo library.
        + modify configure script to allow building shared libraries with gcc
          on AIX 5 or 6 (adapted from patch by Lital Natan).

20081220
        + modify to omit the opaque-functions from lib_gen.o when
          --disable-ext-funcs is used.
        + add test/clip_printw.c to illustrate how to use printw without
          wrapping.
        + modify ncurses 'F' test to demo wborder_set() with colored lines.
        + modify ncurses 'f' test to demo wborder() with colored lines.

20081213
        + add check for failure to open hashed-database needed for db4.6
          (GenToo #245370).
        + corrected --without-manpages option; previous change only suppressed
          the auxiliary rules install.man and uninstall.man
        + add case for FreeMINT to configure macro CF_XOPEN_SOURCE (patch from
          GenToo #250454).
        + fixes from NetBSD port at
          http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/devel/ncurses/patches
          patch-ac (build-fix for DragonFly)
          patch-ae (use INSTALL_SCRIPT for installing misc/ncurses*-config).
        + improve configure script macros CF_HEADER_PATH and CF_LIBRARY_PATH
          by adding CFLAGS, CPPFLAGS and LDFLAGS, LIBS values to the
          search-lists.
        + correct title string for keybound manpage (patch by Frederic Culot,
          OpenBSD documentation/6019),

20081206
        + move del_curterm() call from _nc_freeall() to _nc_leaks_tinfo() to
          work for progs/clear, progs/tabs, etc.
        + correct buffer-size after internal resizing of wide-character
          set_field_buffer(), broken in 20081018 changes (report by Mike Gran).
        + add "-i" option to test/filter.c to tell it to use initscr() rather
          than newterm(), to investigate report on comp.unix.programmer that
          ncurses would clear the screen in that case (it does not - the issue
          was xterm's alternate screen feature).
        + add check in mouse-driver to disable connection if GPM returns a
          zero, indicating that the connection is closed (Debian #506717,
          adapted from patch by Samuel Thibault).

20081129
        + improve a workaround in adding wide-characters, when a control
          character is found.  The library (cf: 20040207) uses unctrl() to
          obtain a printable version of the control character, but was not
          passing color or video attributes.
        + improve test/ncurses.c 'a' test, using unctrl() more consistently to
          display meta-characters.
        + turn on _XOPEN_CURSES definition in curses.h
        + add eterm-color entry (report by Vincent Lefevre) -TD
        + correct use of key_name() in test/ncurses.c 'A' test, which only
          displays wide-characters, not key-codes since 20070612 (report by
          Ricardo Cantu).

20081122
        + change _nc_has_mouse() to has_mouse(), reflect its use in C++ and
          Ada95 (patch by Juergen Pfeifer).
        + document in TO-DO an issue with Cygwin's package for GNAT (report
          by Mike Dennison).
        + improve error-checking of command-line options in "tabs" program.

20081115
        + change several terminfo entries to make consistent use of ANSI
          clear-all-tabs -TD
        + add "tabs" program (prompted by Debian #502260).
        + add configure --without-manpages option (request by Mike Frysinger).

20081102 5.7 release for upload to ftp.gnu.org

20081025
        + add a manpage to discuss memory leaks.
        + add support for shared libraries for QNX (other than libtool, which
          does not work well on that platform).
        + build-fix for QNX C++ binding.

20081018
        + build-fixes for OS/2 EMX.
        + modify form library to accept control characters such as newline
          in set_field_buffer(), which is compatible with Solaris (report by
          Nit Khair).
        + modify configure script to assume --without-hashed-db when
          --disable-database is used.
        + add "-e" option in ncurses/Makefile.in when generating source-files
          to force earlier exit if the build environment fails unexpectedly
          (prompted by patch by Adrian Bunk).
        + change configure script to use CF_UTF8_LIB, improved variant of
          CF_LIBUTF8.

20081012
        + add teraterm4.59 terminfo entry, use that as primary teraterm entry, rename
          original to teraterm2.3 -TD
        + update "gnome" terminfo to 2.22.3 -TD
        + update "konsole" terminfo to 1.6.6, needs today's fix for tic -TD
        + add "aterm" terminfo -TD
        + add "linux2.6.26" terminfo -TD
        + add logic to tic for cancelling strings in user-defined capabilities,
          overlooked til now.

20081011
        + regenerated html documentation.
        + add -m and -s options to test/keynames.c and test/key_names.c to test
          the meta() function with keyname() or key_name(), respectively.
        + correct return value of key_name() on error; it is null.
        + document some unresolved issues for rpath and pthreads in TO-DO.
        + fix a missing prototype for ioctl() on OpenBSD in tset.c
        + add configure option --disable-tic-depends to make explicit whether
          tic library depends on ncurses/ncursesw library, amends change from
          20080823 (prompted by Debian #501421).

20081004
        + some build-fixes for configure --disable-ext-funcs (incomplete, but
          works for C/C++ parts).
        + improve configure-check for awks unable to handle large strings, e.g.
          AIX 5.1 whose awk silently gives up on large printf's.

20080927
        + fix build for --with-dmalloc by workaround for redefinition of
          strndup between string.h and dmalloc.h
        + fix build for --disable-sigwinch
        + add environment variable NCURSES_GPM_TERMS to allow override to use
          GPM on terminals other than "linux", etc.
        + disable GPM mouse support when $TERM does not happen to contain
          "linux", since Gpm_Open() no longer limits its assertion to terminals
          that it might handle, e.g., within "screen" in xterm.
        + reset mouse file-descriptor when unloading GPM library (report by
          Miroslav Lichvar).
        + fix build for --disable-leaks --enable-widec --with-termlib
        > patch by Juergen Pfeifer:
        + use improved initialization for soft-label keys in Ada95 sample code.
        + discard internal symbol _nc_slk_format (unused since 20080112).
        + move call of slk_paint_info() from _nc_slk_initialize() to
          slk_intern_refresh(), improving initialization.

20080925
        + fix bug in mouse code for GPM from 20080920 changes (reported in
          Debian #500103, also Miroslav Lichvar).

20080920
        + fix shared-library rules for cygwin with tic- and tinfo-libraries.
        + fix a memory leak when failure to connect to GPM.
        + correct check for notimeout() in wgetch() (report on linux.redhat
          newsgroup by FurtiveBertie).
        + add an example warning-suppression file for valgrind,
          misc/ncurses.supp (based on example from Reuben Thomas)

20080913
        + change shared-library configuration for OpenBSD, make rpath work.
        + build-fixes for using libutf8, e.g., on OpenBSD 3.7

20080907
        + corrected fix for --enable-weak-symbols (report by Frederic L W

20080906
        + corrected gcc options for building shared libraries on IRIX64.
        + add configure check for awk programs unable to handle big-strings,
          use that to improve the default for --enable-big-strings option.
        + makefile-fixes for --enable-weak-symbols (report by Frederic L W
          Meunier).
        + update test/configure script.
        + adapt ifdef's from library to make test/view.c build when mbrtowc()
          is unavailable, e.g., with HPUX 10.20.
        + add configure check for wcsrtombs, mbsrtowcs, which are used in
          test/ncurses.c, and use wcstombs, mbstowcs instead if available,
          fixing build of ncursew for HPUX 11.00

20080830
        + fixes to make Ada95 demo_panels() example work.
        + modify Ada95 'rain' test program to accept keyboard commands like the
          C-version.
        + modify BeOS-specific ifdef's to build on Haiku (patch by Scott
          Mccreary).
        + add configure-check to see if the std namespace is legal for cerr
          and endl, to fix a build issue with Tru64.
        + consistently use NCURSES_BOOL in lib_gen.c
        + filter #line's from lib_gen.c
        + change delimiter in MKlib_gen.sh from '%' to '@', to avoid
          substitution by IBM xlc to '#' as part of its extensions to digraphs.
        + update config.guess, config.sub from
                http://savannah.gnu.org/projects/config
          (caveat - its maintainer removed support for older Linux systems).

20080823
        + modify configure check for pthread library to work with OSF/1 5.1,
          which uses #define's to associate its header and library.
        + use pthread_mutexattr_init() for initializing pthread_mutexattr_t,
          makes threaded code work on HPUX 11.23
        + fix a bug in demo_menus in freeing menus (cf: 20080804).
        + modify configure script for the case where tic library is used (and
          possibly renamed) to remove its dependency upon ncurses/ncursew
          library (patch by Dr Werner Fink).
        + correct manpage for menu_fore() which gave wrong default for
          the attribute used to display a selected entry (report by Mike Gran).
        + add Eterm-256color, Eterm-88color and rxvt-88color (prompted by
          Debian #495815) -TD

20080816
        + add configure option --enable-weak-symbols to turn on new feature.
        + add configure-check for availability of weak symbols.
        + modify linkage with pthread library to use weak symbols so that
          applications not linked to that library will not use the mutexes,
          etc.  This relies on gcc, and may be platform-specific (patch by Dr
          Werner Fink).
        + add note to INSTALL to document limitation of renaming of tic library
          using the --with-ticlib configure option (report by Dr Werner Fink).
        + document (in manpage) why tputs does not detect I/O errors (prompted
          by comments by Samuel Thibault).
        + fix remaining warnings from Klocwork report.

20080804
        + modify _nc_panelhook() data to account for a permanent memory leak.
        + fix memory leaks in test/demo_menus
        + fix most warnings from Klocwork tool (report by Larry Zhou).
        + modify configure script CF_XOPEN_SOURCE macro to add case for
          "dragonfly" from xterm #236 changes.
        + modify configure script --with-hashed-db to let $LIBS override the
          search for the db library (prompted by report by Samson Pierre).

20080726
        + build-fixes for gcc 4.3.1 (changes to gnat "warnings", and C inlining
          thresholds).

20080713
        + build-fix (reports by Christian Ebert, Funda Wang).

20080712
        + compiler-warning fixes for Solaris.

20080705
        + use NCURSES_MOUSE_MASK() in definition of BUTTON_RELEASE(), etc., to
          make those work properly with the "--enable-ext-mouse" configuration
          (cf: 20050205).
        + improve documentation of build-cc options in INSTALL.
        + work-around a bug in gcc 4.2.4 on AIX, which does not pass the
          -static/-dynamic flags properly to linker, causing test/bs to
          not link.

20080628
        + correct some ifdef's needed for the broken-linker configuration.
        + make debugging library's $BAUDRATE feature work for termcap
          interface.
        + make $NCURSES_NO_PADDING feature work for termcap interface (prompted
          by comment on FreeBSD mailing list).
        + add screen.mlterm terminfo entry -TD
        + improve mlterm and mlterm+pcfkeys terminfo entries -TD

20080621
        + regenerated html documentation.
        + expand manpage description of parameters for form_driver() and
          menu_driver() (prompted by discussion with Adam Spragg).
        + add null-pointer checks for cur_term in baudrate() and
          def_shell_mode(), def_prog_mode()
        + fix some memory leaks in delscreen() and wide acs.

20080614
        + modify test/ditto.c to illustrate multi-threaded use_screen().
        + change CC_SHARED_OPTS from -KPIC to -xcode=pic32 for Solaris.
        + add "-shared" option to MK_SHARED_LIB for gcc on Solaris (report
          by Poor Yorick).

20080607
        + finish changes to wgetch(), making it switch as needed to the
          window's actual screen when calling wrefresh() and wgetnstr().  That
          allows wgetch() to get used concurrently in different threads with
          some minor restrictions, e.g., the application should not delete a
          window which is being used in a wgetch().
        + simplify mutex's, combining the window- and screen-mutex's.

20080531
        + modify wgetch() to use the screen which corresponds to its window
          parameter rather than relying on SP; some dependent functions still
          use SP internally.
        + factor out most use of SP in lib_mouse.c, using parameter.
        + add internal _nc_keyname(), replacing keyname() to associate with a
          particular SCREEN rather than the global SP.
        + add internal _nc_unctrl(), replacing unctrl() to associate with a
          particular SCREEN rather than the global SP.
        + add internal _nc_tracemouse(), replacing _tracemouse() to eliminate
          its associated global buffer _nc_globals.tracemse_buf now in SCREEN.
        + add internal _nc_tracechar(), replacing _tracechar() to use SCREEN in
          preference to the global _nc_globals.tracechr_buf buffer.

20080524
        + modify _nc_keypad() to make it switch temporarily as needed to the
          screen which must be updated.
        + wrap cur_term variable to help make _nc_keymap() thread-safe, and
          always set the screen's copy of this variable in set_curterm().
        + restore curs_set() state after endwin()/refresh() (report/patch
          Miroslav Lichvar)

20080517
        + modify configure script to note that --enable-ext-colors and
          --enable-ext-mouse are not experimental, but extensions from
          the ncurses ABI 5.
        + corrected manpage description of setcchar() (discussion with
          Emanuele Giaquinta).
        + fix for adding a non-spacing character at the beginning of a line
          (report/patch by Miroslav Lichvar).

20080503
        + modify screen.* terminfo entries using new screen+fkeys to fix
          overridden keys in screen.rxvt (Debian #478094) -TD
        + modify internal interfaces to reduce wgetch()'s dependency on the
          global SP.
        + simplify some loops with macros each_screen(), each_window() and
          each_ripoff().

20080426
        + continue modifying test/ditto.c toward making it demonstrate
          multithreaded use_screen(), using fifos to pass data between screens.
        + fix typo in form.3x (report by Mike Gran).

20080419
        + add screen.rxvt terminfo entry -TD
        + modify tic -f option to format spaces as \s to prevent them from
          being lost when that is read back in unformatted strings.
        + improve test/ditto.c, using a "talk"-style layout.

20080412
        + change test/ditto.c to use openpty() and xterm.
        + add locks for copywin(), dupwin(), overlap(), overlay() on their
          window parameters.
        + add locks for initscr() and newterm() on updates to the SCREEN
          pointer.
        + finish table in curs_thread.3x manpage.

20080405
        + begin table in curs_thread.3x manpage describing the scope of data
          used by each function (or symbol) for threading analysis.
        + add null-pointer checks to setsyx() and getsyx() (prompted by
          discussion by Martin v. Lowis and Jeroen Ruigrok van der Werven on
          python-dev2 mailing list).

20080329
        + add null-pointer checks in set_term() and delscreen().
        + move _nc_windows into _nc_globals, since windows can be pads, which
          are not associated with a particular screen.
        + change use_screen() to pass the SCREEN* parameter rather than
          stdscr to the callback function.
        + force libtool to use tag for 'CC' in case it does not detect this,
          e.g., on aix when using CC=powerpc-ibm-aix5.3.0.0-gcc
          (report/patch by Michael Haubenwallner).
        + override OBJEXT to "lo" when building with libtool, to work on
          platforms such as AIX where libtool may use a different suffix for
          the object files than ".o" (report/patch by Michael Haubenwallner).
        + add configure --with-pthread option, for building with the POSIX
          thread library.

20080322
        + fill in extended-color pair two more places in wbkgrndset() and
          waddch_nosync() (prompted by Sedeno's patch).
        + fill in extended-color pair in _nc_build_wch() to make colors work
          for wide-characters using extended-colors (patch by Alejandro R
          Sedeno).
        + add x/X toggles to ncurses.c C color test to test/demo
          wide-characters with extended-colors.
        + add a/A toggles to ncurses.c c/C color tests.
        + modify test/ditto.c to use use_screen().
        + finish modifying test/rain.c to demonstrate threads.

20080308
        + start modifying test/rain.c for threading demo.
        + modify test/ncurses.c to make 'f' test accept the f/F/b/F/</> toggles
          that the 'F' accepts.
        + modify test/worm.c to show trail in reverse-video when other threads
          are working concurrently.
        + fix a deadlock from improper nesting of mutexes for windowlist and
          window.

20080301
        + fixes from 20080223 resolved issue with mutexes; change to use
          recursive mutexes to fix memory leak in delwin() as called from
          _nc_free_and_exit().

20080223
        + fix a size-difference in _nc_globals which caused hanging of mutex
          lock/unlock when termlib was built separately.

20080216
        + avoid using nanosleep() in threaded configuration since that often
          is implemented to suspend the entire process.

20080209
        + update test programs to build/work with various UNIX curses for
          comparisons.  This was to reinvestigate statement in X/Open Curses
          that insnstr and winsnstr perform wrapping.  None of the Unix-branded
          implementations do this, as noted in manpage (cf: 20040228).

20080203
        + modify _nc_setupscreen() to set the legacy-coding value the same
          for both narrow/wide models.  It had been set only for wide model,
          but is needed to make unctrl() work with locale in the narrow model.
        + improve waddch() and winsch() handling of EILSEQ from mbrtowc() by
          using unctrl() to display illegal bytes rather than trying to append
          further bytes to make up a valid sequence (reported by Andrey A
          Chernov).
        + modify unctrl() to check codes in 128-255 range versus isprint().
          If they are not printable, and locale was set, use a "M-" or "~"
          sequence.

20080126
        + improve threading in test/worm.c (wrap refresh calls, and KEY_RESIZE
          handling).  Now it hangs in napms(), no matter whether nanosleep()
          or poll() or select() are used on Linux.

20080119
        + fixes to build with --disable-ext-funcs
        + add manpage for use_window and use_screen.
        + add set_tabsize() and set_escdelay() functions.

20080112
        + remove recursive-mutex definitions, finish threading demo for worm.c
        + remove a redundant adjustment of lines in resizeterm.c's
          adjust_window() which caused occasional misadjustment of stdscr when
          softkeys were used.

20080105
        + several improvements to terminfo entries based on xterm #230 -TD
        + modify MKlib_gen.sh to handle keyname/key_name prototypes, so the
          "link_test" builds properly.
        + fix for toe command-line options -u/-U to ensure filename is given.
        + fix allocation-size for command-line parsing in infocmp from 20070728
          (report by Miroslav Lichvar)
        + improve resizeterm() by moving ripped-off lines, and repainting the
          soft-keys (report by Katarina Machalkova)
        + add clarification in wclear's manpage noting that the screen will be
          cleared even if a subwindow is cleared (prompted by Christer Enfors
          question).
        + change test/ncurses.c soft-key tests to work with KEY_RESIZE.

20071222
        + continue implementing support for threading demo by adding mutex
          for delwin().

20071215
        + add several functions to C++ binding which wrap C functions that
          pass a WINDOW* parameter (request by Chris Lee).

20071201
        + add note about configure options needed for Berkeley database to the
          INSTALL file.
        + improve checks for version of Berkeley database libraries.
        + amend fix for rpath to not modify LDFLAGS if the platform has no
          applicable transformation (report by Christian Ebert, cf: 20071124).

20071124
        + modify configure option --with-hashed-db to accept a parameter which
          is the install-prefix of a given Berkeley Database (prompted by
          pierre4d2 comments).
        + rewrite wrapper for wcrtomb(), making it work on Solaris.  This is
          used in the form library to determine the length of the buffer needed
          by field_buffer (report by Alfred Fung).
        + remove unneeded window-parameter from C++ binding for wresize (report
          by Chris Lee).

20071117
        + modify the support for filesystems which do not support mixed-case to
          generate 2-character (hexadecimal) codes for the lower-level of the
          filesystem terminfo database (request by Michail Vidiassov).
        + add configure option --enable-mixed-case, to allow overriding the
          configure script's check if the filesystem supports mixed-case
          filenames.
        + add wresize() to C++ binding (request by Chris Lee).
        + define NCURSES_EXT_FUNCS and NCURSES_EXT_COLORS in curses.h to make
          it simpler to tell if the extended functions and/or colors are
          declared.

20071103
        + update memory-leak checks for changes to names.c and codes.c
        + correct acsc strings in h19, z100 (patch by Benjamin C W Sittler).

20071020
        + continue implementing support for threading demo by adding mutex
          for use_window().
        + add mrxvt terminfo entry, add/fix xterm building blocks for modified
          cursor keys -TD
        + compile with FreeBSD "contemporary" TTY interface (patch by
          Rong-En Fan).

20071013
        + modify makefile rules to allow clear, tput and tset to be built
          without libtic.  The other programs (infocmp, tic and toe) rely on
          that library.
        + add/modify null-pointer checks in several functions for SP and/or
          the WINDOW* parameter (report by Thorben Krueger).
        + fixes for field_buffer() in formw library (see Redhat #310071,
          patches by Miroslav Lichvar).
        + improve performance of NCURSES_CHAR_EQ code (patch by Miroslav
          Lichvar).
        + update/improve mlterm and rxvt terminfo entries, e.g., for
          the modified cursor- and keypad-keys -TD

20071006
        + add code to curses.priv.h ifdef'd with NCURSES_CHAR_EQ, which
          changes the CharEq() macro to an inline function to allow comparing
          cchar_t struct's without comparing gaps in a possibly unpacked
          memory layout (report by Miroslav Lichvar).

20070929
        + add new functions to lib_trace.c to setup mutex's for the _tracef()
          calls within the ncurses library.
        + for the reentrant model, move _nc_tputs_trace and _nc_outchars into
          the SCREEN.
        + start modifying test/worm.c to provide threading demo (incomplete).
        + separated ifdef's for some BSD-related symbols in tset.c, to make
          it compile on LynxOS (report by Greg Gemmer).
20070915
        + modify Ada95/gen/Makefile to use shlib script, to simplify building
          shared-library configuration on platforms lacking rpath support.
        + build-fix for Ada95/src/Makefile to reflect changed dependency for
          the terminal-interface-curses-aux.adb file which is now generated.
        + restructuring test/worm.c, for use_window() example.

20070908
        + add use_window() and use_screen() functions, to develop into support
          for threaded library (incomplete).
        + fix typos in man/curs_opaque.3x which kept the install script from
          creating symbolic links to two aliases created in 20070818 (report by
          Rong-En Fan).

20070901
        + remove a spurious newline from output of html.m4, which caused links
          for Ada95 html to be incorrect for the files generated using m4.
        + start investigating mutex's for SCREEN manipulation (incomplete).
        + minor cleanup of codes.c/names.c for --enable-const
        + expand/revise "Routine and Argument Names" section of ncurses manpage
          to address report by David Givens in newsgroup discussion.
        + fix interaction between --without-progs/--with-termcap configure
          options (report by Michail Vidiassov).
        + fix typo in "--disable-relink" option (report by Michail Vidiassov).

20070825
        + fix a sign-extension bug in infocmp's repair_acsc() function
          (cf: 971004).
        + fix old configure script bug which prevented "--disable-warnings"
          option from working (patch by Mike Frysinger).

20070818
        + add 9term terminal description (request by Juhapekka Tolvanen) -TD
        + modify comp_hash.c's string output to avoid misinterpreting a null
          "\0" followed by a digit.
        + modify MKnames.awk and MKcodes.awk to support big-strings.
          This only applies to the cases (broken linker, reentrant) where
          the corresponding arrays are accessed via wrapper functions.
        + split MKnames.awk into two scripts, eliminating the shell redirection
          which complicated the make process and also the bogus timestamp file
          which was introduced to fix "make -j".
        + add test/test_opaque.c, test/test_arrays.c
        + add wgetscrreg() and wgetparent() for applications that may need it
          when NCURSES_OPAQUE is defined (prompted by Bryan Christ).

20070812
        + amend treatment of infocmp "-r" option to retain the 1023-byte limit
          unless "-T" is given (cf: 981017).
        + modify comp_captab.c generation to use big-strings.
        + make _nc_capalias_table and _nc_infoalias_table private accessed via
          _nc_get_alias_table() since the tables are used only within the tic
          library.
        + modify configure script to skip Intel compiler in CF_C_INLINE.
        + make _nc_info_hash_table and _nc_cap_hash_table private accessed via
          _nc_get_hash_table() since the tables are used only within the tic
          library.

20070728
        + make _nc_capalias_table and _nc_infoalias_table private, accessed via
          _nc_get_alias_table() since they are used only by parse_entry.c
        + make _nc_key_names private since it is used only by lib_keyname.c
        + add --disable-big-strings configure option to control whether
          unctrl.c is generated using the big-string optimization - which may
          use strings longer than supported by a given compiler.
        + reduce relocation tables for tic, infocmp by changing type of
          internal hash tables to short, and make those private symbols.
        + eliminate large fixed arrays from progs/infocmp.c

20070721
        + change winnstr() to stop at the end of the line (cf: 970315).
        + add test/test_get_wstr.c
        + add test/test_getstr.c
        + add test/test_inwstr.c
        + add test/test_instr.c

20070716
        + restore a call to obtain screen-size in _nc_setupterm(), which
          is used in tput and other non-screen applications via setupterm()
          (Debian #433357, reported by Florent Bayle, Christian Ohm,
          cf: 20070310).

20070714
        + add test/savescreen.c test-program
        + add check to trace-file open, if the given name is a directory, add
          ".log" to the name and try again.
        + add konsole-256color entry -TD
        + add extra gcc warning options from xterm.
        + minor fixes for ncurses/hashmap test-program.
        + modify configure script to quiet c++ build with libtool when the
          --disable-echo option is used.
        + modify configure script to disable ada95 if libtool is selected,
          writing a warning message (addresses FreeBSD #114493).
        + update config.guess, config.sub

20070707
        + add continuous-move "M" to demo_panels to help test refresh changes.
        + improve fix for refresh of window on top of multi-column characters,
          taking into account some split characters on left/right window
          boundaries.

20070630
        + add "widec" row to _tracedump() output to help diagnose remaining
          problems with multi-column characters.
        + partial fix for refresh of window on top of multi-column characters
          which are partly overwritten (report by Sadrul H Chowdhury).
        + ignore A_CHARTEXT bits in vidattr() and vid_attr(), in case
          multi-column extension bits are passed there.
        + add setlocale() call to demo_panels.c, needed for wide-characters.
        + add some output flags to _nc_trace_ttymode to help diagnose a bug
          report by Larry Virden, i.e., ONLCR, OCRNL, ONOCR and ONLRET,

20070623
        + add test/demo_panels.c
        + implement opaque version of setsyx() and getsyx().

20070612
        + corrected xterm+pcf2 terminfo modifiers for F1-F4, to match xterm
          #226 -TD
        + split-out key_name() from MKkeyname.awk since it now depends upon
          wunctrl() which is not in libtinfo (report by Rong-En Fan).

20070609
        + add test/key_name.c
        + add stdscr cases to test/inchs.c and test/inch_wide.c
        + update test/configure
        + correct formatting of DEL (0x7f) in _nc_vischar().
        + null-terminate result of wunctrl().
        + add null-pointer check in key_name() (report by Andreas Krennmair,
          cf: 20020901).

20070602
        + adapt mouse-handling code from menu library in form-library
          (discussion with Clive Nicolson).
        + add a modification of test/dots.c, i.e., test/dots_mvcur.c to
          illustrate how to use mvcur().
        + modify wide-character flavor of SetAttr() to preserve the
          WidecExt() value stored in the .attr field, e.g., in case it
          is overwritten by chgat (report by Aleksi Torhamo).
        + correct buffer-size for _nc_viswbuf2n() (report by Aleksi Torhamo).
        + build-fixes for Solaris 2.6 and 2.7 (patch by Peter O'Gorman).

20070526
        + modify keyname() to use "^X" form only if meta() has been called, or
          if keyname() is called without initializing curses, e.g., via
          initscr() or newterm() (prompted by LinuxBase #1604).
        + document some portability issues in man/curs_util.3x
        + add a shadow copy of TTY buffer to _nc_prescreen to fix applications
          broken by moving that data into SCREEN (cf: 20061230).

20070512
        + add 'O' (wide-character panel test) in ncurses.c to demonstrate a
          problem reported by Sadrul H Chowdhury with repainting parts of
          a fullwidth cell.
        + modify slk_init() so that if there are preceding calls to
          ripoffline(), those affect the available lines for soft-keys (adapted
          from patch by Clive Nicolson).
        + document some portability issues in man/curs_getyx.3x

20070505
        + fix a bug in Ada95/samples/ncurses which caused a variable to
          become uninitialized in the "b" test.
        + fix Ada95/gen/Makefile.in adahtml rule to account for recent
          movement of files, fix a few incorrect manpage references in the
          generated html.
        + add Ada95 binding to _nc_freeall() as Curses_Free_All to help with
          memory-checking.
        + correct some functions in Ada95 binding which were using return value
          from C where none was returned:  idcok(), immedok() and wtimeout().
        + amend recent changes for Ada95 binding to make it build with
          Cygwin's linker, e.g., with configure options
                --enable-broken-linker --with-ticlib

20070428
        + add a configure check for gcc's options for inlining, use that to
          quiet a warning message where gcc's default behavior changed from
          3.x to 4.x.
        + improve warning message when checking if GPM is linked to curses
          library by not warning if its use of "wgetch" is via a weak symbol.
        + add loader options when building with static libraries to ensure that
          an installed shared library for ncurses does not conflict.  This is
          reported as problem with Tru64, but could affect other platforms
          (report Martin Mokrejs, analysis by Tim Mooney).
        + fix build on cygwin after recent ticlib/termlib changes, i.e.,
          + adjust TINFO_SUFFIX value to work with cygwin's dll naming
          + revert a change from 20070303 which commented out dependency of
            SHLIB_LIST in form/menu/panel/c++ libraries.
        + fix initialization of ripoff stack pointer (cf: 20070421).

20070421
        + move most static variables into structures _nc_globals and
          _nc_prescreen, to simplify storage.
        + add/use configure script macro CF_SIG_ATOMIC_T, use the corresponding
          type for data manipulated by signal handlers (prompted by comments
          in mailing.openbsd.bugs newsgroup).
        + modify CF_WITH_LIBTOOL to allow one to pass options such as -static
          to the libtool create- and link-operations.

20070414
        + fix whitespace in curs_opaque.3x which caused a spurious ';' in
          the installed aliases (report by Peter Santoro).
        + fix configure script to not try to generate adacurses-config when
          Ada95 tree is not built.

20070407
        + add man/curs_legacy.3x, man/curs_opaque.3x
        + fix acs_map binding for Ada95 when --enable-reentrant is used.
        + add adacurses-config to the Ada95 install, based on version from
          FreeBSD port, in turn by Juergen Pfeifer in 2000 (prompted by
          comment on comp.lang.ada newsgroup).
        + fix includes in c++ binding to build with Intel compiler
          (cf: 20061209).
        + update install rule in Ada95 to use mkdirs.sh
        > other fixes prompted by inspection for Coverity report:
        + modify ifdef's for c++ binding to use try/catch/throw statements
        + add a null-pointer check in tack/ansi.c request_cfss()
        + fix a memory leak in ncurses/base/wresize.c
        + corrected check for valid memu/meml capabilities in
          progs/dump_entry.c when handling V_HPUX case.
        > fixes based on Coverity report:
        + remove dead code in test/bs.c
        + remove dead code in test/demo_defkey.c
        + remove an unused assignment in progs/infocmp.c
        + fix a limit check in tack/ansi.c tools_charset()
        + fix tack/ansi.c tools_status() to perform the VT320/VT420
          tests in request_cfss().  The function had exited too soon.
        + fix a memory leak in tic.c's make_namelist()
        + fix a couple of places in tack/output.c which did not check for EOF.
        + fix a loop-condition in test/bs.c
        + add index checks in lib_color.c for color palettes
        + add index checks in progs/dump_entry.c for version_filter() handling
          of V_BSD case.
        + fix a possible null-pointer dereference in copywin()
        + fix a possible null-pointer dereference in waddchnstr()
        + add a null-pointer check in _nc_expand_try()
        + add a null-pointer check in tic.c's make_namelist()
        + add a null-pointer check in _nc_expand_try()
        + add null-pointer checks in test/cardfile.c
        + fix a double-free in ncurses/tinfo/trim_sgr0.c
        + fix a double-free in ncurses/base/wresize.c
        + add try/catch block to c++/cursesmain.cc

20070331
        + modify Ada95 binding to build with --enable-reentrant by wrapping
          global variables (bug: acs_map does not yet work).
        + modify Ada95 binding to use the new access-functions, allowing it
          to build/run when NCURSES_OPAQUE is set.
        + add access-functions and macros to return properties of the WINDOW
          structure, e.g., when NCURSES_OPAQUE is set.
        + improved install-sh's quoting.
        + use mkdirs.sh rather than mkinstalldirs, e.g., to use fixes from
          other programs.

20070324
        + eliminate part of the direct use of WINDOW data from Ada95 interface.
        + fix substitutions for termlib filename to make configure option
          --enable-reentrant work with --with-termlib.
        + change a constructor for NCursesWindow to allow compiling with
          NCURSES_OPAQUE set, since we cannot pass a reference to
          an opaque pointer.

20070317
        + ignore --with-chtype=unsigned since unsigned is always added to
          the type in curses.h; do the same for --with-mmask-t.
        + change warning regarding --enable-ext-colors and wide-character
          in the configure script to an error.
        + tweak error message in CF_WITH_LIBTOOL to distinguish other programs
          such as Darwin's libtool program (report by Michail Vidiassov)
        + modify edit_man.sh to allow for multiple substitutions per line.
        + set locale in misc/ncurses-config.in since it uses a range
        + change permissions libncurses++.a install (report by Michail
          Vidiassov).
        + corrected length of temporary buffer in wide-character version
          of set_field_buffer() (related to report by Bryan Christ).

20070311
        + fix mk-1st.awk script install_shlib() function, broken in 20070224
          changes for cygwin (report by  Michail Vidiassov).

20070310
        + increase size of array in _nc_visbuf2n() to make "tic -v" work
          properly in its similar_sgr() function (report/analysis by Peter
          Santoro).
        + add --enable-reentrant configure option for ongoing changes to
          implement a reentrant version of ncurses:
          + libraries are suffixed with "t"
          + wrap several global variables (curscr, newscr, stdscr, ttytype,
            COLORS, COLOR_PAIRS, COLS, ESCDELAY, LINES and TABSIZE) as
            functions returning values stored in SCREEN or cur_term.
          + move some initialization (LINES, COLS) from lib_setup.c,
            i.e., setupterm() to _nc_setupscreen(), i.e., newterm().

20070303
        + regenerated html documentation.
        + add NCURSES_OPAQUE symbol to curses.h, will use to make structs
          opaque in selected configurations.
        + move the chunk in lib_acs.c which resets acs capabilities when
          running on a terminal whose locale interferes with those into
          _nc_setupscreen(), so the libtinfo/libtinfow files can be made
          identical (requested by Miroslav Lichvar).
        + do not use configure variable SHLIB_LIBS for building libraries
          outside the ncurses directory, since that symbol is customized
          only for that directory, and using it introduces an unneeded
          dependency on libdl (requested by Miroslav Lichvar).
        + modify mk-1st.awk so the generated makefile rules for linking or
          installing shared libraries do not first remove the library, in
          case it is in use, e.g., libncurses.so by /bin/sh (report by Jeff
          Chua).
        + revised section "Using NCURSES under XTERM" in ncurses-intro.html
          (prompted by newsgroup comment by Nick Guenther).

20070224
        + change internal return codes of _nc_wgetch() to check for cases
          where KEY_CODE_YES should be returned, e.g., if a KEY_RESIZE was
          ungetch'd, and read by wget_wch().
        + fix static-library build broken in 20070217 changes to remove "-ldl"
          (report by Miroslav Lichvar).
        + change makefile/scripts for cygwin to allow building termlib.
        + use Form_Hook in manpages to match form.h
        + use Menu_Hook in manpages, as well as a few places in menu.h
        + correct form- and menu-manpages to use specific Field_Options,
          Menu_Options and Item_Options types.
        + correct prototype for _tracechar() in manpage (cf: 20011229).
        + correct prototype for wunctrl() in manpage.

20070217
        + fixes for $(TICS_LIST) in ncurses/Makefile (report by Miroslav
          Lichvar).
        + modify relinking of shared libraries to apply only when rpath is
          enabled, and add --disable-relink option which can be used to
          disable the feature altogether (reports by Michail Vidiassov,
          Adam J Richter).
        + fix --with-termlib option for wide-character configuration, stripping
          the "w" suffix in one place (report by Miroslav Lichvar).
        + remove "-ldl" from some library lists to reduce dependencies in
          programs (report by Miroslav Lichvar).
        + correct description of --enable-signed-char in configure --help
          (report by Michail Vidiassov).
        + add pattern for GNU/kFreeBSD configuration to CF_XOPEN_SOURCE,
          which matches an earlier change to CF_SHARED_OPTS, from xterm #224
          fixes.
        + remove "${DESTDIR}" from -install_name option used for linking
          shared libraries on Darwin (report by Michail Vidiassov).

20070210
        + add test/inchs.c, test/inch_wide.c, to test win_wchnstr().
        + remove libdl from library list for termlib (report by Miroslav
          Lichvar).
        + fix configure.in to allow --without-progs --with-termlib (patch by
          Miroslav Lichvar).
        + modify win_wchnstr() to ensure that only a base cell is returned
          for each multi-column character (prompted by report by Wei Kong
          regarding change in mvwin_wch() cf: 20041023).

20070203
        + modify fix_wchnstr() in form library to strip attributes (and color)
          from the cchar_t array (field cells) read from a field's window.
          Otherwise, when copying the field cells back to the window, the
          associated color overrides the field's background color (report by
          Ricardo Cantu).
        + improve tracing for form library, showing created forms, fields, etc.
        + ignore --enable-rpath configure option if --with-shared was omitted.
        + add _nc_leaks_tinfo(), _nc_free_tic(), _nc_free_tinfo() entrypoints
          to allow leak-checking when both tic- and tinfo-libraries are built.
        + drop CF_CPP_VSCAN_FUNC macro from configure script, since C++ binding
          no longer relies on it.
        + disallow combining configure script options --with-ticlib and
          --enable-termcap (report by Rong-En Fan).
        + remove tack from ncurses tree.

20070128
        + fix typo in configure script that broke --with-termlib option
          (report by Rong-En Fan).

20070127
        + improve fix for FreeBSD gnu/98975, to allow for null pointer passed
          to tgetent() (report by Rong-en Fan).
        + update tack/HISTORY and tack/README to tell how to build it after
          it is removed from the ncurses tree.
        + fix configure check for libtool's version to trim blank lines
          (report by sci-fi@hush.ai).
        + review/eliminate other original-file artifacts in cursesw.cc, making
          its license consistent with ncurses.
        + use ncurses vw_scanw() rather than reading into a fixed buffer in
          the c++ binding for scanw() methods (prompted by report by Nuno Dias).
        + eliminate fixed-buffer vsprintf() calls in c++ binding.

20070120
        + add _nc_leaks_tic() to separate leak-checking of tic library from
          term/ncurses libraries, and thereby eliminate a library dependency.
        + fix test/mk-test.awk to ignore blank lines.
        + correct paths in include/headers, for --srcdir (patch by Miroslav
          Lichvar).

20070113
        + add a break-statement in misc/shlib to ensure that it exits on the
          _first_ matched directory (report by Paul Novak).
        + add tack/configure, which can be used to build tack outside the
          ncurses build-tree.
        + add --with-ticlib option, to build/install the tic-support functions
          in a separate library (suggested by Miroslav Lichvar).

20070106
        + change MKunctrl.awk to reduce relocation table for unctrl.o
        + change MKkeyname.awk to reduce relocation table for keyname.o
          (patch by Miroslav Lichvar).

20061230
        + modify configure check for libtool's version to trim blank lines
          (report by sci-fi@hush.ai).
        + modify some modules to allow them to be reentrant if _REENTRANT is
          defined: lib_baudrate.c, resizeterm.c (local data only)
        + eliminate static data from some modules: add_tries.c, hardscroll.c,
          lib_ttyflags.c, lib_twait.c
        + improve manpage install to add aliases for the transformed program
          names, e.g., from --program-prefix.
        + used linklint to verify links in the HTML documentation, made fixes
          to manpages as needed.
        + fix a typo in curs_mouse.3x (report by William McBrine).
        + fix install-rule for ncurses5-config to make the bin-directory.

20061223
        + modify configure script to omit the tic (terminfo compiler) support
          from ncurses library if --without-progs option is given.
        + modify install rule for ncurses5-config to do this via "install.libs"
        + modify shared-library rules to allow FreeBSD 3.x to use rpath.
        + update config.guess, config.sub

20061217 5.6 release for upload to ftp.gnu.org

20061217
        + add ifdef's for <wctype.h> for HPUX, which has the corresponding
          definitions in <wchar.h>.
        + revert the va_copy() change from 20061202, since it was neither
          correct nor portable.
        + add $(LOCAL_LIBS) definition to progs/Makefile.in, needed for
          rpath on Solaris.
        + ignore wide-acs line-drawing characters that wcwidth() claims are
          not one-column.  This is a workaround for Solaris' broken locale
          support.

20061216
        + modify configure --with-gpm option to allow it to accept a parameter,
          i.e., the name of the dynamic GPM library to load via dlopen()
          (requested by Bryan Henderson).
        + add configure option --with-valgrind, changes from vile.
        + modify configure script AC_TRY_RUN and AC_TRY_LINK checks to use
          'return' in preference to 'exit()'.

20061209
        + change default for --with-develop back to "no".
        + add XTABS to tracing of TTY bits.
        + updated autoconf patch to ifdef-out the misfeature which declares
          exit() for configure tests.  This fixes a redefinition warning on
          Solaris.
        + use ${CC} rather than ${LD} in shared library rules for IRIX64,
          Solaris to help ensure that initialization sections are provided for
          extra linkage requirements, e.g., of C++ applications (prompted by
          comment by Casper Dik in newsgroup).
        + rename "$target" in CF_MAN_PAGES to make it easier to distinguish
          from the autoconf predefined symbol.  There was no conflict,
          since "$target" was used only in the generated edit_man.sh file,
          but SuSE's rpm package contains a patch.

20061202
        + update man/term.5 to reflect extended terminfo support and hashed
          database configuration.
        + updates for test/configure script.
        + adapted from SuSE rpm package:
          + remove long-obsolete workaround for broken-linker which declared
            cur_term in tic.c
          + improve error recovery in PUTC() macro when wcrtomb() does not
            return usable results for an 8-bit character.
        + patches from rpm package (SuSE):
          + use va_copy() in extra varargs manipulation for tracing version
            of printw, etc.
          + use a va_list rather than a null in _nc_freeall()'s call to
            _nc_printf_string().
        + add some see-also references in manpages to show related
          wide-character functions (suggested by Claus Fischer).

20061125
        + add a check in lib_color.c to ensure caller does not increase COLORS
          above max_colors, which is used as an array index (discussion with
          Simon Sasburg).
        + add ifdef's allowing ncurses to be built with tparm() using either
          varargs (the existing status), or using a fixed-parameter list (to
          match X/Open).

20061104
        + fix redrawing of windows other than stdscr using wredrawln() by
          touching the corresponding rows in curscr (discussion with Dan
          Gookin).
        + add test/redraw.c
        + add test/echochar.c
        + review/cleanup manpage descriptions of error-returns for form- and
          menu-libraries (prompted by FreeBSD docs/46196).

20061028
        + add AUTHORS file -TD
        + omit the -D options from output of the new config script --cflags
          option (suggested by Ralf S Engelschall).
        + make NCURSES_INLINE unconditionally defined in curses.h

20061021
        + revert change to accommodate bash 3.2, since that breaks other
          platforms, e.g., Solaris.
        + minor fixes to NEWS file to simplify scripting to obtain list of
          contributors.
        + improve some shared-library configure scripting for Linux, FreeBSD
          and NetBSD to make "--with-shlib-version" work.
        + change configure-script rules for FreeBSD shared libraries to allow
          for rpath support in versions past 3.
        + use $(DESTDIR) in makefile rules for installing/uninstalling the
          package config script (reports/patches by Christian Wiese,
          Ralf S Engelschall).
        + fix a warning in the configure script for NetBSD 2.0, working around
          spurious blanks embedded in its ${MAKEFLAGS} symbol.
        + change test/Makefile to simplify installing test programs in a
          different directory when --enable-rpath is used.

20061014
        + work around bug in bash 3.2 by adding extra quotes (Jim Gifford).
        + add/install a package config script, e.g., "ncurses5-config" or
          "ncursesw5-config", according to configuration options.

20061007
        + add several GNU Screen terminfo variations with 16- and 256-colors,
          and status line (Alain Bench).
        + change the way shared libraries (other than libtool) are installed.
          Rather than copying the build-tree's libraries, link the shared
          objects into the install directory.  This makes the --with-rpath
          option work except with $(DESTDIR) (cf: 20000930).

20060930
        + fix ifdef in c++/internal.h for QNX 6.1
        + test-compiled with (old) egcs-1.1.2, modified configure script to
          not unset the $CXX and related variables which would prevent this.
        + fix a few terminfo.src typos exposed by improvements to "-f" option.
        + improve infocmp/tic "-f" option formatting.

20060923
        + make --disable-largefile option work (report by Thomas M Ott).
        + updated html documentation.
        + add ka2, kb1, kb3, kc2 to vt220-keypad as an extension -TD
        + minor improvements to rxvt+pcfkeys -TD

20060916
        + move static data from lib_mouse.c into SCREEN struct.
        + improve ifdef's for _POSIX_VDISABLE in tset to work with Mac OS X
          (report by Michail Vidiassov).
        + modify CF_PATH_SYNTAX to ensure it uses the result from --prefix
          option (from lynx changes) -TD
        + adapt AC_PROG_EGREP check, noting that this is likely to be another
          place aggravated by POSIXLY_CORRECT.
        + modify configure check for awk to ensure that it is found (prompted
          by report by Christopher Parker).
        + update config.sub

20060909
        + add kon, kon2 and jfbterm terminfo entry (request by Till Maas) -TD
        + remove invis capability from klone+sgr, mainly used by linux entry,
          since it does not really do this -TD

20060903
        + correct logic in wadd_wch() and wecho_wch(), which did not guard
          against passing the multi-column attribute into a call on waddch(),
          e.g., using data returned by win_wch() (cf: 20041023)
          (report by Sadrul H Chowdhury).

20060902
        + fix kterm's acsc string -TD
        + fix for change to tic/infocmp in 20060819 to ensure no blank is
          embedded into a termcap description.
        + workaround for 20050806 ifdef's change to allow visbuf.c to compile
          when using --with-termlib --with-trace options.
        + improve tgetstr() by making the return value point into the user's
          buffer, if provided (patch by Miroslav Lichvar (see Redhat #202480)).
        + correct libraries needed for foldkeys (report by Stanislav Ievlev)

20060826
        + add terminfo entries for xfce terminal (xfce) and multi gnome
          terminal (mgt) -TD
        + add test/foldkeys.c

20060819
        + modify tic and infocmp to avoid writing trailing blanks on terminfo
          source output (Debian #378783).
        + modify configure script to ensure that if the C compiler is used
          rather than the loader in making shared libraries, the $(CFLAGS)
          variable is also used (Redhat #199369).
        + port hashed-db code to db2 and db3.
        + fix a bug in tgetent() from 20060625 and 20060715 changes
          (patch/analysis by Miroslav Lichvar (see Redhat #202480)).

20060805
        + updated xterm function-keys terminfo to match xterm #216 -TD
        + add configure --with-hashed-db option (tested only with FreeBSD 6.0,
          e.g., the db 1.8.5 interface).

20060729
        + modify toe to access termcap data, e.g., via cgetent() functions,
          or as a text file if those are not available.
        + use _nc_basename() in tset to improve $SHELL check for csh/sh.
        + modify _nc_read_entry() and _nc_read_termcap_entry() so infocmp,
          can access termcap data when the terminfo database is disabled.

20060722
        + widen the test for xterm kmous a little to allow for other strings
          than \E[M, e.g., for xterm-sco functionality in xterm.
        + update xterm-related terminfo entries to match xterm patch #216 -TD
        + update config.guess, config.sub

20060715
        + fix for install-rule in Ada95 to add terminal_interface.ads
          and terminal_interface.ali (anonymous posting in comp.lang.ada).
        + correction to manpage for getcchar() (report by William McBrine).
        + add test/chgat.c
        + modify wchgat() to mark updated cells as changed so a refresh will
          repaint those cells (comments by Sadrul H Chowdhury and William
          McBrine).
        + split up dependency of names.c and codes.c in ncurses/Makefile to
          work with parallel make (report/analysis by Joseph S Myers).
        + suppress a warning message (which is ignored) for systems without
          an ldconfig program (patch by Justin Hibbits).
        + modify configure script --disable-symlinks option to allow one to
          disable symlink() in tic even when link() does not work (report by
          Nigel Horne).
        + modify MKfallback.sh to use tic -x when constructing fallback tables
          to allow extended capabilities to be retrieved from a fallback entry.
        + improve leak-checking logic in tgetent() from 20060625 to ensure that
          it does not free the current screen (report by Miroslav Lichvar).

20060708
        + add a check for _POSIX_VDISABLE in tset (NetBSD #33916).
        + correct _nc_free_entries() and related functions used for memory leak
          checking of tic.

20060701
        + revert a minor change for magic-cookie support from 20060513, which
          caused unexpected reset of attributes, e.g., when resizing test/view
          in color mode.
        + note in clear manpage that the program ignores command-line
          parameters (prompted by Debian #371855).
        + fixes to make lib_gen.c build properly with changes to the configure
          --disable-macros option and NCURSES_NOMACROS (cf:  20060527)
        + update/correct several terminfo entries -TD
        + add some notes regarding copyright to terminfo.src -TD

20060625
        + fixes to build Ada95 binding with gnat-4.1.0
        + modify read_termtype() so the term_names data is always allocated as
          part of the str_table, a better fix for a memory leak (cf: 20030809).
        + reduce memory leaks in repeated calls to tgetent() by remembering the
          last TERMINAL* value allocated to hold the corresponding data and
          freeing that if the tgetent() result buffer is the same as the
          previous call (report by "Matt" for FreeBSD gnu/98975).
        + modify tack to test extended capability function-key strings.
        + improved gnome terminfo entry (GenToo #122566).
        + improved xterm-256color terminfo entry (patch by Alain Bench).

20060617
        + fix two small memory leaks related to repeated tgetent() calls
          with TERM=screen (report by "Matt" for FreeBSD gnu/98975).
        + add --enable-signed-char to simplify Debian package.
        + reduce name-pollution in term.h by removing #define's for HAVE_xxx
          symbols.
        + correct typo in curs_terminfo.3x (Debian #369168).

20060603
        + enable the mouse in test/movewindow.c
        + improve a limit-check in frm_def.c (John Heasley).
        + minor copyright fixes.
        + change configure script to produce test/Makefile from data file.

20060527
        + add a configure option --enable-wgetch-events to enable
          NCURSES_WGETCH_EVENTS, and correct the associated loop-logic in
          lib_twait.c (report by Bernd Jendrissek).
        + remove include/nomacros.h from build, since the ifdef for
          NCURSES_NOMACROS makes that obsolete.
        + add entrypoints for some functions which were only provided as macros
          to make NCURSES_NOMACROS ifdef work properly:  getcurx(), getcury(),
          getbegx(), getbegy(), getmaxx(), getmaxy(), getparx() and getpary(),
          wgetbkgrnd().
        + provide ifdef for NCURSES_NOMACROS which suppresses most macro
          definitions from curses.h, i.e., where a macro is defined to override
          a function to improve performance.  Allowing a developer to suppress
          these definitions can simplify some application (discussion with
          Stanislav Ievlev).
        + improve description of memu/meml in terminfo manpage.

20060520
        + if msgr is false, reset video attributes when doing an automargin
          wrap to the next line.  This makes the ncurses 'k' test work properly
          for hpterm.
        + correct caching of keyname(), which was using only half of its table.
        + minor fixes to memory-leak checking.
        + make SCREEN._acs_map and SCREEN._screen_acs_map pointers rather than
          arrays, making ACS_LEN less visible to applications (suggested by
          Stanislav Ievlev).
        + move chunk in SCREEN ifdef'd for USE_WIDEC_SUPPORT to the end, so
          _screen_acs_map will have the same offset in both ncurses/ncursesw,
          making the corresponding tinfo/tinfow libraries binary-compatible
          (cf: 20041016, report by Stanislav Ievlev).

20060513
        + improve debug-tracing for EmitRange().
        + change default for --with-develop to "yes".  Add NCURSES_NO_HARD_TABS
          and NCURSES_NO_MAGIC_COOKIE environment variables to allow runtime
          suppression of the related hard-tabs and xmc-glitch features.
        + add ncurses version number to top-level manpages, e.g., ncurses, tic,
          infocmp, terminfo as well as form, menu, panel.
        + update config.guess, config.sub
        + modify ncurses.c to work around a bug in NetBSD 3.0 curses
          (field_buffer returning null for a valid field).  The 'r' test
          appears to not work with that configuration since the new_fieldtype()
          function is broken in that implementation.

20060506
        + add hpterm-color terminfo entry -TD
        + fixes to compile test-programs with HPUX 11.23

20060422
        + add copyright notices to files other than those that are generated,
          data or adapted from pdcurses (reports by William McBrine, David
          Taylor).
        + improve rendering on hpterm by not resetting attributes at the end
          of doupdate() if the terminal has the magic-cookie feature (report
          by Bernd Rieke).
        + add 256color variants of terminfo entries for programs which are
          reported to implement this feature -TD

20060416
        + fix typo in change to NewChar() macro from 20060311 changes, which
          broke tab-expansion (report by Frederic L W Meunier).

20060415
        + document -U option of tic and infocmp.
        + modify tic/infocmp to suppress smacs/rmacs when acsc is suppressed
          due to size limit, e.g., converting to termcap format.  Also
          suppress them if the output format does not contain acsc and it
          was not VT100-like, i.e., a one-one mapping (Novell #163715).
        + add configure check to ensure that SIGWINCH is defined on platforms
          such as OS X which exclude that when _XOPEN_SOURCE, etc., are
          defined (report by Nicholas Cole)

20060408
        + modify write_object() to not write coincidental extensions of an
          entry made due to it being referenced in a use= clause (report by
          Alain Bench).
        + another fix for infocmp -i option, which did not ensure that some
          escape sequences had comparable prefixes (report by Alain Bench).

20060401
        + improve discussion of init/reset in terminfo and tput manpages
          (report by Alain Bench).
        + use is3 string for a fallback of rs3 in the reset program; it was
          using is2 (report by Alain Bench).
        + correct logic for infocmp -i option, which did not account for
          multiple digits in a parameter (cf: 20040828) (report by Alain
          Bench).
        + move _nc_handle_sigwinch() to lib_setup.c to make --with-termlib
          option work after 20060114 changes (report by Arkadiusz Miskiewicz).
        + add copyright notices to test-programs as needed (report by William
          McBrine).

20060318
        + modify ncurses.c 'F' test to combine the wide-characters with color
          and/or video attributes.
        + modify test/ncurses to use CTL/Q or ESC consistently for exiting
          a test-screen (some commands used 'x' or 'q').

20060312
        + fix an off-by-one in the scrolling-region change (cf_ 20060311).

20060311
        + add checks in waddchnstr() and wadd_wchnstr() to stop copying when
          a null character is found (report by Igor Bogomazov).
        + modify progs/Makefile.in to make "tput init" work properly with
          cygwin, i.e., do not pass a ".exe" in the reference string used
          in check_aliases (report by Samuel Thibault).
        + add some checks to ensure current position is within scrolling
          region before scrolling on a new line (report by Dan Gookin).
        + change some NewChar() usage to static variables to work around
          stack garbage introduced when cchar_t is not packed (Redhat #182024).

20060225
        + workarounds to build test/movewindow with PDcurses 2.7.
        + fix for nsterm-16color entry (patch by Alain Bench).
        + correct a typo in infocmp manpage (Debian #354281).

20060218
        + add nsterm-16color entry -TD
        + updated mlterm terminfo entry -TD
        + remove 970913 feature for copying subwindows as they are moved in
          mvwin() (discussion with Bryan Christ).
        + modify test/demo_menus.c to demonstrate moving a menu (both the
          window and subwindow) using shifted cursor-keys.
        + start implementing recursive mvwin() in movewindow.c (incomplete).
        + add a fallback definition for GCC_PRINTFLIKE() in test.priv.h,
          for movewindow.c (report by William McBrine).
        + add help-message to test/movewindow.c

20060211
        + add test/movewindow.c, to test mvderwin().
        + fix ncurses soft-key test so color changes are shown immediately
          rather than delayed.
        + modify ncurses soft-key test to hide the keys when exiting the test
          screen.
        + fixes to build test programs with PDCurses 2.7, e.g., its headers
          rely on autoconf symbols, and it declares stubs for nonfunctional
          terminfo and termcap entrypoints.

20060204
        + improved test/configure to build test/ncurses on HPUX 11 using the
          vendor curses.
        + documented ALTERNATE CONFIGURATIONS in the ncurses manpage, for the
          benefit of developers who do not read INSTALL.

20060128
        + correct form library Window_To_Buffer() change (cf:  20040516), which
          should ignore the video attributes (report by Ricardo Cantu).

20060121
        + minor fixes to xmc-glitch experimental code:
          + suppress line-drawing
          + implement max_attributes
          tested with xterm.
        + minor fixes for the database iterator.
        + fix some buffer limits in c++ demo (comment by Falk Hueffner in
          Debian #348117).

20060114
        + add toe -a option, to show all databases.  This uses new private
          interfaces in the ncurses library for iterating through the list of
          databases.
        + fix toe from 20000909 changes which made it not look at
          $HOME/.terminfo
        + make toe's -v option parameter optional as per manpage.
        + improve SIGWINCH handling by postponing its effect during newterm(),
          etc., when allocating screens.

20060111
        + modify wgetnstr() to return KEY_RESIZE if a sigwinch occurs.  Use
          this in test/filter.c
        + fix an error in filter() modification which caused some applications
          to fail.

20060107
        + check if filter() was called when getting the screensize.  Keep it
          at 1 if so (based on Redhat #174498).
        + add extension nofilter().
        + refined the workaround for ACS mapping.
        + make ifdef's consistent in curses.h for the extended colors so the
          header file can be used for the normal curses library.  The header
          file installed for extended colors is a variation of the
          wide-character configuration (report by Frederic L W Meunier).

20051231
        + add a workaround to ACS mapping to allow applications such as
          test/blue.c to use the "PC ROM" characters by masking them with
          A_ALTCHARSET.  This worked up til 5.5, but was lost in the revision
          of legacy coding (report by Michael Deutschmann).
        + add a null-pointer check in the wide-character version of
          calculate_actual_width() (report by Victor Julien).
        + improve test/ncurses 'd' (color-edit) test by allowing the RGB
          values to be set independently (patch by William McBrine).
        + modify test/configure script to allow building test programs with
          PDCurses/X11.
        + modified test programs to allow some to work with NetBSD curses.
          Several do not because NetBSD curses implements a subset of X/Open
          curses, and also lacks much of SVr4 additions.  But it's enough for
          comparison.
        + update config.guess and config.sub

20051224
        + use BSD-specific fix for return-value from cgetent() from CVS where
          an unknown terminal type would be reportd as "database not found".
        + make tgetent() return code more readable using new symbols
          TGETENT_YES, etc.
        + remove references to non-existent "tctest" program.
        + remove TESTPROGS from progs/Makefile.in (it was referring to code
          that was never built in that directory).
        + typos in curs_addchstr.3x, some doc files (noticed in OpenBSD CVS).

20051217
        + add use_legacy_coding() function to support lynx's font-switching
          feature.
        + fix formatting in curs_termcap.3x (report by Mike Frysinger).
        + modify MKlib_gen.sh to change preprocessor-expanded _Bool back to
          bool.

20051210
        + extend test/ncurses.c 's' (overlay window) test to exercise overlay(),
          overwrite() and copywin() with different combinations of colors and
          attributes (including background color) to make it easy to see the
          effect of the different functions.
        + corrections to menu/m_global.c for wide-characters (report by
          Victor Julien).

20051203
        + add configure option --without-dlsym, allowing developers to
          configure GPM support without using dlsym() (discussion with Michael
          Setzer).
        + fix wins_nwstr(), which did not handle single-column non-8bit codes
          (Debian #341661).

20051126
        + move prototypes for wide-character trace functions from curses.tail
          to curses.wide to avoid accidental reference to those if
          _XOPEN_SOURCE_EXTENDED is defined without ensuring that <wchar.h> is
          included.
        + add/use NCURSES_INLINE definition.
        + change some internal functions to use int/unsigned rather than the
          short equivalents.

20051119
        + remove a redundant check in lib_color.c (Debian #335655).
        + use ld's -search_paths_first option on Darwin to work around odd
          search rules on that platform (report by Christian Gennerat, analysis
          by Andrea Govoni).
        + remove special case for Darwin in CF_XOPEN_SOURCE configure macro.
        + ignore EINTR in tcgetattr/tcsetattr calls (Debian #339518).
        + fix several bugs in test/bs.c (patch by Stephen Lindholm).

20051112
        + other minor fixes to cygwin based on tack -TD
        + correct smacs in cygwin (Debian #338234, report by Baurzhan
          Ismagulov, who noted that it was fixed in Cygwin).

20051029
        + add shifted up/down arrow codes to xterm-new as kind/kri strings -TD
        + modify wbkgrnd() to avoid clearing the A_CHARTEXT attribute bits
          since those record the state of multicolumn characters (Debian
          #316663).
        + modify werase to clear multicolumn characters that extend into
          a derived window (Debian #316663).

20051022
        + move assignment from environment variable ESCDELAY from initscr()
          down to newterm() so the environment variable affects timeouts for
          terminals opened with newterm() as well.
        + fix a memory leak in keyname().
        + add test/demo_altkeys.c
        + modify test/demo_defkey.c to exit from loop via 'q' to allow
          leak-checking, as well as fix a buffer size in winnstr() call.

20051015
        + correct order of use-clauses in rxvt-basic entry which made codes for
          f1-f4 vt100-style rather than vt220-style (report by Gabor Z Papp).
        + suppress configure check for gnatmake if Ada95/Makefile.in is not
          found.
        + correct a typo in configure --with-bool option for the case where
          --without-cxx is used (report by Daniel Jacobowitz).
        + add a note to INSTALL's discussion of --with-normal, pointing out
          that one may wish to use --without-gpm to ensure a completely
          static link (prompted by report by Felix von Leitner).

20051010 5.5 release for upload to ftp.gnu.org

20051008
        + document in demo_forms.c some portability issues.

20051001
        + document side-effect of werase() which sets the cursor position.
        + save/restore the current position in form field editing to make
          overlay mode work.

20050924
        + correct header dependencies in progs, allowing parallel make (report
          by Daniel Jacobowitz).
        + modify CF_BUILD_CC to ensure that pre-setting $BUILD_CC overrides
          the configure check for --with-build-cc (report by Daniel Jacobowitz).
        + modify CF_CFG_DEFAULTS to not use /usr as the default prefix for
          NetBSD.
        + update config.guess and config.sub from
                http://subversions.gnu.org/cgi-bin/viewcvs/config/config/

20050917
        + modify sed expression which computes path for /usr/lib/terminfo
          symbolic link in install to ensure that it does not change unexpected
          levels of the path (Gentoo #42336).
        + modify default for --disable-lp64 configure option to reduce impact
          on existing 64-bit builds.  Enabling the _LP64 option may change the
          size of chtype and mmask_t.  However, for ABI 6, it is enabled by
          default (report by Mike Frysinger).
        + add configure script check for --enable-ext-mouse, bump ABI to 6 by
          default if it is used.
        + improve configure script logic for bumping ABI to omit this if the
          --with-abi-version option was used.
        + update address for Free Software Foundation in tack's source.
        + correct wins_wch(), which was not marking the filler-cells of
          multi-column characters (cf:  20041023).

20050910
        + modify mouse initialization to ensure that Gpm_Open() is called only
          once.  Otherwise GPM gets confused in its initialization of signal
          handlers (Debian #326709).

20050903
        + modify logic for backspacing in a multiline form field to ensure that
          it works even when the preceding line is full (report by Frank van
          Vugt).
        + remove comment about BUGS section of ncurses manpage (Debian #325481)

20050827
        + document some workarounds for shared and libtool library
          configurations in INSTALL (see --with-shared and --with-libtool).
        + modify CF_GCC_VERSION and CF_GXX_VERSION macros to accommodate
          cross-compilers which emit the platform name in their version
          message, e.g.,
                arm-sa1100-linux-gnu-g++ (GCC) 4.0.1
          (report by Frank van Vugt).

20050820
        + start updating documentation for upcoming 5.5 release.
        + fix to make libtool  and libtinfo work together again (cf: 20050122).
        + fixes to allow building traces into libtinfo
        + add debug trace to tic that shows if/how ncurses will write to the
          lower corner of a terminal's screen.
        + update llib-l* files.

20050813
        + modify initializers in c++ binding to build with old versions of g++.
        + improve special case for 20050115 repainting fix, ensuring that if
          the first changed cell is not a character that the range to be
          repainted is adjusted to start at a character's beginning (Debian
          #316663).

20050806
        + fixes to build on QNX 6.1
        + improve configure script checks for Intel 9.0 compiler.
        + remove #include's for libc.h (obsolete).
        + adjust ifdef's in curses.priv.h so that when cross-compiling to
          produce comp_hash and make_keys, no dependency on wchar.h is needed.
          That simplifies the build-cppflags (report by Frank van Vugt).
        + move modules related to key-binding into libtinfo to fix linkage
          problem caused by 20050430 changes to MKkeyname.sh (report by
          Konstantin Andreev).

20050723
        + updates/fixes for configure script macros from vile -TD
        + make prism9's sgr string agree with the rest of the terminfo -TD
        + make vt220's sgr0 string consistent with sgr string, do this for
          several related cases -TD
        + improve translation to termcap by filtering the 'me' (sgr0) strings
          as in the runtime call to tgetent() (prompted by a discussion with
          Thomas Klausner).
        + improve tic check for sgr0 versus sgr(0), to help ensure that sgr0
          resets line-drawing.

20050716
        + fix special cases for trimming sgr0 for hurd and vt220 (Debian
          #318621).
        + split-out _nc_trim_sgr0() from modifications made to tgetent(), to
          allow it to be used by tic to provide information about the runtime
          changes that would be made to sgr0 for termcap applications.
        + modify make_sed.sh to make the group-name in the NAME section of
          form/menu library manpage agree with the TITLE string when renaming
          is done for Debian (Debian #78866).

20050702
        + modify parameter type in c++ binding for insch() and mvwinsch() to
          be consistent with underlying ncurses library (was char, is chtype).
        + modify treatment of Intel compiler to allow _GNU_SOURCE to be defined
          on Linux.
        + improve configure check for nanosleep(), checking that it works since
          some older systems such as AIX 4.3 have a nonworking version.

20050625
        + update config.guess and config.sub from
                http://subversions.gnu.org/cgi-bin/viewcvs/config/config/
        + modify misc/shlib to work in test-directory.
        + suppress $suffix in misc/run_tic.sh when cross-compiling.  This
          allows cross-compiles to use the host's tic program to handle the
          "make install.data" step.
        + improve description of $LINES and $COLUMNS variables in manpages
          (prompted by report by Dave Ulrick).
        + improve description of cross-compiling in INSTALL
        + add NCURSES-Programming-HOWTO.html by Pradeep Padala
          (see http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/).
        + modify configure script to obtain soname for GPM library (discussion
          with Daniel Jacobowitz).
        + modify configure script so that --with-chtype option will still
          compute the unsigned literals suffix for constants in curses.h
          (report by Daniel Jacobowitz:
        + patches from Daniel Jacobowitz:
          + the man_db.renames entry for tack.1 was backwards.
          + tack.1 had some 1m's that should have been 1M's.
          + the section for curs_inwstr.3 was wrong.

20050619
        + correction to --with-chtype option (report by Daniel Jacobowitz).

20050618
        + move build-time edit_man.sh and edit_man.sed scripts to top directory
          to simplify reusing them for renaming tack's manpage (prompted by a
          review of Debian package).
        + revert minor optimization from 20041030 (Debian #313609).
        + libtool-specific fixes, tested with libtool 1.4.3, 1.5.0, 1.5.6,
          1.5.10 and 1.5.18 (all work except as noted previously for the c++
          install using libtool 1.5.0):
          + modify the clean-rule in c++/Makefile.in to work with IRIX64 make
            program.
          + use $(LIBTOOL_UNINSTALL) symbol, overlooked in 20030830
        + add configure options --with-chtype and --with-mmask-t, to allow
          overriding of the non-LP64 model's use of the corresponding types.
        + revise test for size of chtype (and mmask_t), which always returned
          "long" due to an uninitialized variable (report by Daniel Jacobowitz).

20050611
        + change _tracef's that used "%p" format for va_list values to ignore
          that, since on some platforms those are not pointers.
        + fixes for long-formats in printf's due to largefile support.

20050604
        + fixes for termcap support:
          + reset pointer to _nc_curr_token.tk_name when the input stream is
            closed, which could point to free memory (cf: 20030215).
          + delink TERMTYPE data which is used by the termcap reader, so that
            extended names data will be freed consistently.
          + free pointer to TERMTYPE data in _nc_free_termtype() rather than
            its callers.
          + add some entrypoints for freeing permanently allocated data via
            _nc_freeall() when NO_LEAKS is defined.
        + amend 20041030 change to _nc_do_color to ensure that optimization is
          applied only when the terminal supports back_color_erase (bce).

20050528
        + add sun-color terminfo entry -TD
        + correct a missing assignment in c++ binding's method
          NCursesPanel::UserPointer() from 20050409 changes.
        + improve configure check for large-files, adding check for dirent64
          from vile -TD
        + minor change to configure script to improve linker options for the
          Ada95 tree.

20050515
        + document error conditions for ncurses library functions (report by
          Stanislav Ievlev).
        + regenerated html documentation for ada binding.
          see ftp://ftp.invisible-island.net/ncurses/patches/gnathtml

20050507
        + regenerated html documentation for manpages.
        + add $(BUILD_EXEEXT) suffix to invocation of make_keys in
          ncurses/Makefile (Gentoo #89772).
        + modify c++/demo.cc to build with g++ -fno-implicit-templates option
          (patch by Mike Frysinger).
        + modify tic to filter out long extended names when translating to
          termcap format.  Only two characters are permissible for termcap
          capability names.

20050430
        + modify terminfo entries xterm-new and rxvt to add strings for
          shift-, control-cursor keys.
        + workaround to allow c++ binding to compile with g++ 2.95.3, which
          has a broken implementation of static_cast<> (patch by Jeff Chua).
        + modify initialization of key lookup table so that if an extended
          capability (tic -x) string is defined, and its name begins with 'k',
          it will automatically be treated as a key.
        + modify test/keynames.c to allow for the possibility of extended
          key names, e.g., via define_key(), or via "tic -x".
        + add test/demo_termcap.c to show the contents of given entry via the
          termcap interface.

20050423
        + minor fixes for vt100/vt52 entries -TD
        + add configure option --enable-largefile
        + corrected libraries used to build Ada95/gen/gen, found in testing
          gcc 4.0.0.

20050416
        + update config.guess, config.sub
        + modify configure script check for _XOPEN_SOURCE, disable that on
          Darwin whose header files have problems (patch by Chris Zubrzycki).
        + modify form library Is_Printable_String() to use iswprint() rather
          than wcwidth() for determining if a character is printable.  The
          latter caused it to reject menu items containing non-spacing
          characters.
        + modify ncurses test program's F-test to handle non-spacing characters
          by combining them with a reverse-video blank.
        + review/fix several gcc -Wconversion warnings.

20050409
        + correct an off-by-one error in m_driver() for mouse-clicks used to
          position the mouse to a particular item.
        + implement test/demo_menus.c
        + add some checks in lib_mouse to ensure SP is set.
        + modify C++ binding to make 20050403 changes work with the configure
          --enable-const option.

20050403
        + modify start_color() to return ERR if it cannot allocate memory.
        + address g++ compiler warnings in C++ binding by adding explicit
          member initialization, assignment operators and copy constructors.
          Most of the changes simply preserve the existing semantics of the
          binding, which can leak memory, etc., but by making these features
          visible, it provides a framework for improving the binding.
        + improve C++ binding using static_cast, etc.
        + modify configure script --enable-warnings to add options to g++ to
          correspond to the gcc --enable-warnings.
        + modify C++ binding to use some C internal functions to make it
          compile properly on Solaris (and other platforms).

20050327
        + amend change from 20050320 to limit it to configurations with a
          valid locale.
        + fix a bug introduced in 20050320 which broke the translation of
          nonprinting characters to uparrow form (report by Takahashi Tamotsu).

20050326
        + add ifdef's for _LP64 in curses.h to avoid using wasteful 64-bits for
          chtype and mmask_t, but add configure option --disable-lp64 in case
          anyone used that configuration.
        + update misc/shlib script to account for Mac OS X (report by Michail
          Vidiassov).
        + correct comparison for wrapping multibyte characters in
          waddch_literal() (report by Takahashi Tamotsu).

20050320
        + add -c and -w options to tset to allow user to suppress ncurses'
          resizing of the terminal emulator window in the special case where it
          is not able to detect the true size (report by Win Delvaux, Debian
          #300419).
        + modify waddch_nosync() to account for locale zn_CH.GBK, which uses
          codes 128-159 as part of multibyte characters (report by Wang
          WenRui, Debian #300512).

20050319
        + modify ncurses.c 'd' test to make it work with 88-color
          configuration, i.e., by implementing scrolling.
        + improve scrolling in ncurses.c 'c' and 'C' tests, e.g., for 88-color
          configuration.

20050312
        + change tracemunch to use strict checking.
        + modify ncurses.c 'p' test to test line-drawing within a pad.
        + implement environment variable NCURSES_NO_UTF8_ACS to support
          miscellaneous terminal emulators which ignore alternate character
          set escape sequences when in UTF-8 mode.

20050305
        + change NCursesWindow::err_handler() to a virtual function (request by
          Steve Beal).
        + modify fty_int.c and fty_num.c to handle wide characters (report by
          Wolfgang Gutjahr).
        + adapt fix for fty_alpha.c to fty_alnum.c, which also handled normal
          and wide characters inconsistently (report by Wolfgang Gutjahr).
        + update llib-* files to reflect internal interface additions/changes.

20050226
        + improve test/configure script, adding tests for _XOPEN_SOURCE, etc.,
          from lynx.
        + add aixterm-16color terminfo entry -TD
        + modified xterm-new terminfo entry to work with tgetent() changes -TD
        + extended changes in tgetent() from 20040710 to allow the substring of
          sgr0 which matches rmacs to be at the beginning of the sgr0 string
          (request by Thomas Wolff).  Wolff says the visual effect in
          combination with pre-20040710 ncurses is improved.
        + fix off-by-one in winnstr() call which caused form field validation
          of multibyte characters to ignore the last character in a field.
        + correct logic in winsch() for inserting multibyte strings; the code
          would clear cells after the insertion rather than push them to the
          right (cf: 20040228).
        + fix an inconsistency in Check_Alpha_Field() between normal and wide
          character logic (report by Wolfgang Gutjahr).

20050219
        + fix a bug in editing wide-characters in form library: deleting a
          nonwide character modified the previous wide-character.
        + update manpage to describe NCURSES_MOUSE_VERSION 2.
        + correct manpage description of mouseinterval() (Debian #280687).
        + add a note to default_colors.3x explaining why this extension was
          added (Debian #295083).
        + add traces to panel library.

20050212
        + improve editing of wide-characters in form library:  left/right
          cursor movement, and single-character deletions work properly.
        + disable GPM mouse support when $TERM happens to be prefixed with
          "xterm".  Gpm_Open() would otherwise assert that it can deal with
          mouse events in this case.
        + modify GPM mouse support so it closes the server connection when
          the caller disables the mouse (report by Stanislav Ievlev).

20050205
        + add traces for callback functions in form library.
        + add experimental configure option --enable-ext-mouse, which defines
          NCURSES_MOUSE_VERSION 2, and modifies the encoding of mouse events to
          support wheel mice, which may transmit buttons 4 and 5.  This works
          with xterm and similar X terminal emulators (prompted by question by
          Andreas Henningsson, this is also related to Debian #230990).
        + improve configure macros CF_XOPEN_SOURCE and CF_POSIX_C_SOURCE to
          avoid redefinition warnings on cygwin.

20050129
        + merge remaining development changes for extended colors (mostly
          complete, does not appear to break other configurations).
        + add xterm-88color.dat (part of extended colors testing).
        + improve _tracedump() handling of color pairs past 96.
        + modify return-value from start_color() to return OK if colors have
          already been started.
        + modify curs_color.3x list error conditions for init_pair(),
          pair_content() and color_content().
        + modify pair_content() to return -1 for consistency with init_pair()
          if it corresponds to the default-color.
        + change internal representation of default-color to allow application
          to use color number 255.  This does not affect the total number of
          color pairs which are allowed.
        + add a top-level tags rule.

20050122
        + add a null-pointer check in wgetch() in case it is called without
          first calling initscr().
        + add some null-pointer checks for SP, which is not set by libtinfo.
        + modify misc/shlib to ensure that absolute pathnames are used.
        + modify test/Makefile.in, etc., to link test programs only against the
          libraries needed, e.g., omit form/menu/panel library for the ones
          that are curses-specific.
        + change SP->_current_attr to a pointer, adjust ifdef's to ensure that
          libtinfo.so and libtinfow.so have the same ABI.  The reason for this
          is that the corresponding data which belongs to the upper-level
          ncurses library has a different size in each model (report by
          Stanislav Ievlev).

20050115
        + minor fixes to allow test-compiles with g++.
        + correct column value shown in tic's warnings, which did not account
          for leading whitespace.
        + add a check in _nc_trans_string() for improperly ended strings, i.e.,
          where a following line begins in column 1.
        + modify _nc_save_str() to return a null pointer on buffer overflow.
        + improve repainting while scrolling wide-character data (Eungkyu Song).

20050108
        + merge some development changes to extend color capabilities.

20050101
        + merge some development changes to extend color capabilities.
        + fix manpage typo (FreeBSD report docs/75544).
        + update config.guess, config.sub
        > patches for configure script (Albert Chin-A-Young):
        + improved fix to make mbstate_t recognized on HPUX 11i (cf:
          20030705), making vsscanf() prototype visible on IRIX64.  Tested for
          on HP-UX 11i, Solaris 7, 8, 9, AIX 4.3.3, 5.2, Tru64 UNIX 4.0D, 5.1,
          IRIX64 6.5, Redhat Linux 7.1, 9, and RHEL 2.1, 3.0.
        + print the result of the --disable-home-terminfo option.
        + use -rpath when compiling with SGI C compiler.

20041225
        + add trace calls to remaining public functions in form and menu
          libraries.
        + fix check for numeric digits in test/ncurses.c 'b' and 'B' tests.
        + fix typo in test/ncurses.c 'c' test from 20041218.

20041218
        + revise test/ncurses.c 'c' color test to improve use for xterm-88color
          and xterm-256color, added 'C' test using the wide-character color_set
          and attr_set functions.

20041211
        + modify configure script to work with Intel compiler.
        + fix an limit-check in wadd_wchnstr() which caused labels in the
          forms-demo to be one character short.
        + fix typo in curs_addchstr.3x (Jared Yanovich).
        + add trace calls to most functions in form and menu libraries.
        + update working-position for adding wide-characters when window is
          scrolled (prompted by related report by Eungkyu Song).

20041204
        + replace some references on Linux to wcrtomb() which use it to obtain
          the length of a multibyte string with _nc_wcrtomb, since wcrtomb() is
          broken in glibc (see Debian #284260).
        + corrected length-computation in wide-character support for
          field_buffer().
        + some fixes to frm_driver.c to allow it to accept multibyte input.
        + modify configure script to work with Intel 8.0 compiler.

20041127
        + amend change to setupterm() in 20030405 which would reuse the value
          of cur_term if the same output was selected.  This now reuses it only
          when setupterm() is called from tgetent(), which has no notion of
          separate SCREENs.  Note that tgetent() must be called after initscr()
          or newterm() to use this feature (Redhat #140326).
        + add a check in CF_BUILD_CC macro to ensure that developer has given
          the --with-build-cc option when cross-compiling (report by Alexandre
          Campo).
        + improved configure script checks for _XOPEN_SOURCE and
          _POSIX_C_SOURCE (fix for IRIX 5.3 from Georg Schwarz, _POSIX_C_SOURCE
          updates from lynx).
        + cosmetic fix to test/gdc.c to recolor the bottom edge of the box
          for consistency (comment by Dan Nelson).

20041120
        + update wsvt25 terminfo entry -TD
        + modify test/ins_wide.c to test all flavors of ins_wstr().
        + ignore filler-cells in wadd_wchnstr() when adding a cchar_t array
          which consists of multi-column characters, since this function
          constructs them (cf: 20041023).
        + modify winnstr() to return multibyte character strings for the
          wide-character configuration.

20041106
        + fixes to make slk_set() and slk_wset() accept and store multibyte
          or multicolumn characters.

20041030
        + improve color optimization a little by making _nc_do_color() check
          if the old/new pairs are equivalent to the default pair 0.
        + modify assume_default_colors() to not require that
          use_default_colors() be called first.

20041023
        + modify term_attrs() to use termattrs(), add the extended attributes
          such as enter_horizontal_hl_mode for WA_HORIZONTAL to term_attrs().
        + add logic in waddch_literal() to clear orphaned cells when one
          multi-column character partly overwrites another.
        + improved logic for clearing cells when a multi-column character
          must be wrapped to a new line.
        + revise storage of cells for multi-column characters to correct a
          problem with repainting.  In the old scheme, it was possible for
          doupdate() to decide that only part of a multi-column character
          should be repainted since the filler cells stored only an attribute
          to denote them as fillers, rather than the character value and the
          attribute.

20041016
        + minor fixes for traces.
        + add SP->_screen_acs_map[], used to ensure that mapping of missing
          line-drawing characters is handled properly.  For example, ACS_DARROW
          is absent from xterm-new, and it was coincidentally displayed the
          same as ACS_BTEE.

20041009
        + amend 20021221 workaround for broken acs to reset the sgr, rmacs
          and smacs strings as well.  Also modify the check for screen's
          limitations in that area to allow the multi-character shift-in
          and shift-out which seem to work.
        + change GPM initialization, using dl library to load it dynamically
          at runtime (Debian #110586).

20041002
        + correct logic for color pair in setcchar() and getcchar() (patch by
          Marcin 'Qrczak' Kowalczyk).
        + add t/T commands to ncurses b/B tests to allow a different color to
          be tested for the attrset part of the test than is used in the
          background color.

20040925
        + fix to make setcchar() to work when its wchar_t* parameter is
          pointing to a string which contains more data than can be converted.
        + modify wget_wstr() and example in ncurses.c to work if wchar_t and
          wint_t are different sizes (report by Marcin 'Qrczak' Kowalczyk).

20040918
        + remove check in wget_wch() added to fix an infinite loop, appears to
          have been working around a transitory glibc bug, and interferes
          with normal operation (report by Marcin 'Qrczak' Kowalczyk).
        + correct wadd_wch() and wecho_wch(), which did not pass the rendition
          information (report by Marcin 'Qrczak' Kowalczyk).
        + fix aclocal.m4 so that the wide-character version of ncurses gets
          compiled as libncursesw.5.dylib, instead of libncurses.5w.dylib
          (adapted from patch by James J Ramsey).
        + change configure script for --with-caps option to indicate that it
          is no longer experimental.
        + change configure script to reflect the fact that --enable-widec has
          not been "experimental" since 5.3 (report by Bruno Lustosa).

20040911
        + add 'B' test to ncurses.c, to exercise some wide-character functions.

20040828
        + modify infocmp -i option to match 8-bit controls against its table
          entries, e.g., so it can analyze the xterm-8bit entry.
        + add morphos terminfo entry, improve amiga-8bit entry (Pavel Fedin).
        + correct translation of "%%" in terminfo format to termcap, e.g.,
          using "tic -C" (Redhat #130921).
        + modified configure script CF_XOPEN_SOURCE macro to ensure that if
          it defines _POSIX_C_SOURCE, that it defines it to a specific value
          (comp.os.stratus newsgroup comment).

20040821
        + fixes to build with Ada95 binding with gnat 3.4 (all warnings are
          fatal, and gnat does not follow the guidelines for pragmas).
          However that did find a coding error in Assume_Default_Colors().
        + modify several terminfo entries to ensure xterm mouse and cursor
          visibility are reset in rs2 string:  hurd, putty, gnome,
          konsole-base, mlterm, Eterm, screen (Debian #265784, Debian #55637).
          The xterm entries are left alone - old ones for compatibility, and
          the new ones do not require this change. -TD

20040814
        + fake a SIGWINCH in newterm() to accommodate buggy terminal emulators
          and window managers (Debian #265631).
        > terminfo updates -TD
        + remove dch/dch1 from rxvt because they are implemented inconsistently
          with the common usage of bce/ech
        + remove khome from vt220 (vt220's have no home key)
        + add rxvt+pcfkeys

20040807
        + modify test/ncurses.c 'b' test, adding v/V toggles to cycle through
          combinations of video attributes so that for instance bold and
          underline can be tested.  This made the legend too crowded, added
          a help window as well.
        + modify test/ncurses.c 'b' test to cycle through default colors if
          the -d option is set.
        + update putty terminfo entry (Robert de Bath).

20040731
        + modify test/cardfile.c to allow it to read more data than can be
          displayed.
        + correct logic in resizeterm.c which kept it from processing all
          levels of window hierarchy (reports by Folkert van Heusden,
          Chris Share).

20040724
        + modify "tic -cv" to ignore delays when comparing strings.  Also
          modify it to ignore a canceled sgr string, e.g., for terminals which
          cannot properly combine attributes in one control sequence.
        + corrections for gnome and konsole entries (Redhat #122815, patch by
          Hans de Goede)
        > terminfo updates -TD
        + make ncsa-m rmacs/smacs consistent with sgr
        + add sgr, rc/sc and ech to syscons entries
        + add function-keys to decansi
        + add sgr to mterm-ansi
        + add sgr, civis, cnorm to emu
        + correct/simplify cup in addrinfo

20040717
        > terminfo updates -TD
        + add xterm-pc-fkeys
        + review/update gnome and gnome-rh90 entries (prompted by Redhat
          #122815).
        + review/update konsole entries
        + add sgr, correct sgr0 for kterm and mlterm
        + correct tsl string in kterm

20040711
        + add configure option --without-xterm-new

20040710
        + add check in wget_wch() for printable bytes that are not part of a
          multibyte character.
        + modify wadd_wchnstr() to render text using window's background
          attributes.
        + improve tic's check to compare sgr and sgr0.
        + fix c++ directory's .cc.i rule.
        + modify logic in tgetent() which adjusts the termcap "me" string
          to work with ISO-2022 string used in xterm-new (cf: 20010908).
        + modify tic's check for conflicting function keys to omit that if
          converting termcap to termcap format.
        + add -U option to tic and infocmp.
        + add rmam/smam to linux terminfo entry (Trevor Van Bremen)
        > terminfo updates -TD
        + minor fixes for emu
        + add emu-220
        + change wyse acsc strings to use 'i' map rather than 'I'
        + fixes for avatar0
        + fixes for vp3a+

20040703
        + use tic -x to install terminfo database -TD
        + add -x to infocmp's usage message.
        + correct field used for comparing O_ROWMAJOR in set_menu_format()
          (report/patch by Tony Li).
        + fix a missing nul check in set_field_buffer() from 20040508 changes.
        > terminfo updates -TD
          + make xterm-xf86-v43 derived from xterm-xf86-v40 rather than
            xterm-basic -TD
          + align with xterm patch #192's use of xterm-new -TD
          + update xterm-new and xterm-8bit for cvvis/cnorm strings -TD
          + make xterm-new the default "xterm" entry -TD

20040626
        + correct BUILD_CPPFLAGS substitution in ncurses/Makefile.in, to allow
          cross-compiling from a separate directory tree (report/patch by
          Dan Engel).
        + modify is_term_resized() to ensure that window sizes are nonzero,
          as documented in the manpage (report by Ian Collier).
        + modify CF_XOPEN_SOURCE configure macro to make Hurd port build
          (Debian #249214, report/patch by Jeff Bailey).
        + configure-script mods from xterm, e.g., updates to CF_ADD_CFLAGS
        + update config.guess, config.sub
        > terminfo updates -TD
          + add mlterm
          + add xterm-xf86-v44
          + modify xterm-new aka xterm-xfree86 to accommodate luit, which
            relies on G1 being used via an ISO-2022 escape sequence (report by
            Juliusz Chroboczek)
          + add 'hurd' entry

20040619
        + reconsidered winsnstr(), decided after comparing other
          implementations that wrapping is an X/Open documentation error.
        + modify test/inserts.c to test all flavors of insstr().

20040605
        + add setlocale() calls to a few test programs which may require it:
          demo_forms.c, filter.c, ins_wide.c, inserts.c
        + correct a few misspelled function names in ncurses-intro.html (report
          by Tony Li).
        + correct internal name of key_defined() manpage, which conflicted with
          define_key().

20040529
        + correct size of internal pad used for holding wide-character
          field_buffer() results.
        + modify data_ahead() to work with wide-characters.

20040522
        + improve description of terminfo if-then-else expressions (suggested
          by Arne Thomassen).
        + improve test/ncurses.c 'd' test, allow it to use external file for
          initial palette (added xterm-16color.dat and linux-color.dat), and
          reset colors to the initial palette when starting/ending the test.
        + change limit-check in init_color() to allow r/g/b component to
          reach 1000 (cf: 20020928).

20040516
        + modify form library to use cchar_t's rather than char's in the
          wide-character configuration for storing data for field buffers.
        + correct logic of win_wchnstr(), which did not work for more than
          one cell.

20040508
        + replace memset/memcpy usage in form library with for-loops to
          simplify changing the datatype of FIELD.buf, part of wide-character
          changes.
        + fix some inconsistent use of #if/#ifdef (report by Alain Guibert).

20040501
        + modify menu library to account for actual number of columns used by
          multibyte character strings, in the wide-character configuration
          (adapted from patch by Philipp Tomsich).
        + add "-x" option to infocmp like tic's "-x", for use in "-F"
          comparisons.  This modifies infocmp to only report extended
          capabilities if the -x option is given, making this more consistent
          with tic.  Some scripts may break, since infocmp previous gave this
          information without an option.
        + modify termcap-parsing to retain 2-character aliases at the beginning
          of an entry if the "-x" option is used in tic.

20040424
        + minor compiler-warning and test-program fixes.

20040417
        + modify tic's missing-sgr warning to apply to terminfo only.
        + free some memory leaks in tic.
        + remove check in post_menu() that prevented menus from extending
          beyond the screen (request by Max J. Werner).
        + remove check in newwin() that prevents allocating windows
          that extend beyond the screen.  Solaris curses does this.
        + add ifdef in test/color_set.c to allow it to compile with older
          curses.
        + add napms() calls to test/dots.c to make it not be a CPU hog.

20040403
        + modify unctrl() to return null if its parameter does not correspond
          to an unsigned char.
        + add some limit-checks to guard isprint(), etc., from being used on
          values that do not fit into an unsigned char (report by Sami Farin).

20040328
        + fix a typo in the _nc_get_locale() change.

20040327
        + modify _nc_get_locale() to use setlocale() to query the program's
          current locale rather than using getenv().  This fixes a case in tin
          which relies on legacy treatment of 8-bit characters when the locale
          is not initialized (reported by Urs Jansen).
        + add sgr string to screen's and rxvt's terminfo entries -TD.
        + add a check in tic for terminfo entries having an sgr0 but no sgr
          string.  This confuses Tru64 and HPUX curses when combined with
          color, e.g., making them leave line-drawing characters in odd places.
        + correct casts used in ABSENT_BOOLEAN, CANCELLED_BOOLEAN, matches the
          original definitions used in Debian package to fix PowerPC bug before
          20030802 (Debian #237629).

20040320
        + modify PutAttrChar() and PUTC() macro to improve use of
          A_ALTCHARSET attribute to prevent line-drawing characters from
          being lost in situations where the locale would otherwise treat the
          raw data as nonprintable (Debian #227879).

20040313
        + fix a redefinition of CTRL() macro in test/view.c for AIX 5.2 (report
          by Jim Idle).
        + remove ".PP" after ".SH NAME" in a few manpages; this confuses
          some apropos script (Debian #237831).

20040306
        + modify ncurses.c 'r' test so editing commands, like inserted text,
          set the field background, and the state of insert/overlay editing
          mode is shown in that test.
        + change syntax of dummy targets in Ada95 makefiles to work with pmake.
        + correct logic in test/ncurses.c 'b' for noncolor terminals which
          did not recognize a quit-command (cf: 20030419).

20040228
        + modify _nc_insert_ch() to allow for its input to be part of a
          multibyte string.
        + split out lib_insnstr.c, to prepare to rewrite it.  X/Open states
          that this function performs wrapping, unlike all of the other
          insert-functions.  Currently it does not wrap.
        + check for nl_langinfo(CODESET), use it if available (report by
          Stanislav Ievlev).
        + split-out CF_BUILD_CC macro, actually did this for lynx first.
        + fixes for configure script CF_WITH_DBMALLOC and CF_WITH_DMALLOC,
          which happened to work with bash, but not with Bourne shell (report
          by Marco d'Itri via tin-dev).

20040221
        + some changes to adapt the form library to wide characters, incomplete
          (request by Mike Aubury).
        + add symbol to curses.h which can be used to suppress include of
          stdbool.h, e.g.,
                #define NCURSES_ENABLE_STDBOOL_H 0
                #include <curses.h>
          (discussion on XFree86 mailing list).

20040214
        + modify configure --with-termlib option to accept a value which sets
          the name of the terminfo library.  This would allow a packager to
          build libtinfow.so renamed to coincide with libtinfo.so (discussion
          with Stanislav Ievlev).
        + improve documentation of --with-install-prefix, --prefix and
          $(DESTDIR) in INSTALL (prompted by discussion with Paul Lew).
        + add configure check if the compiler can use -c -o options to rename
          its output file, use that to omit the 'cd' command which was used to
          ensure object files are created in a separate staging directory
          (prompted by comments by Johnny Wezel, Martin Mokrejs).

20040208 5.4 release for upload to ftp.gnu.org
        + update TO-DO.

20040207 pre-release
        + minor fixes to _nc_tparm_analyze(), i.e., do not count %i as a param,
          and do not count %d if it follows a %p.
        + correct an inconsistency between handling of codes in the 128-255
          range, e.g., as illustrated by test/ncurses.c f/F tests.  In POSIX
          locale, the latter did not show printable results, while the former
          did.
        + modify MKlib_gen.sh to compensate for broken C preprocessor on Mac
          OS X, which alters "%%" to "% % " (report by Robert Simms, fix
          verified by Scott Corscadden).

20040131 pre-release
        + modify SCREEN struct to align it between normal/wide curses flavors
          to simplify future changes to build a single version of libtinfo
          (patch by Stanislav Ievlev).
        + document handling of carriage return by addch() in manpage.
        + document special features of unctrl() in manpage.
        + documented interface changes in INSTALL.
        + corrected control-char test in lib_addch.c to account for locale
          (Debian #230335, cf: 971206).
        + updated test/configure.in to use AC_EXEEXT and AC_OBJEXT.
        + fixes to compile Ada95 binding with Debian gnat 3.15p-4 package.
        + minor configure-script fixes for older ports, e.g., BeOS R4.5.

20040125 pre-release
        + amend change to PutAttrChar() from 20030614 which computed the number
          of cells for a possibly multi-cell character.  The 20030614 change
          forced the cell to a blank if the result from wcwidth() was not
          greater than zero.  However, wcwidth() called for parameters in the
          range 128-255 can give this return value.  The logic now simply
          ensures that the number of cells is greater than zero without
          modifying the displayed value.

20040124 pre-release
        + looked good for 5.4 release for upload to ftp.gnu.org (but see above)
        + modify configure script check for ranlib to use AC_CHECK_TOOL, since
          that works better for cross-compiling.

20040117 pre-release
        + modify lib_get_wch.c to prefer mblen/mbtowc over mbrlen/mbrtowc to
          work around core dump in Solaris 8's locale support, e.g., for
          zh_CN.GB18030 (report by Saravanan Bellan).
        + add includes for <stdarg.h> and <stdio.h> in configure script macro
          to make <wchar.h> check work with Tru64 4.0d.
        + add terminfo entry for U/Win -TD
        + add terminfo entries for SFU aka Interix aka OpenNT (Federico
          Bianchi).
        + modify tput's error messages to prefix them with the program name
          (report by Vincent Lefevre, patch by Daniel Jacobowitz (see Debian
          #227586)).
        + correct a place in tack where exit_standout_mode was used instead of
          exit_attribute_mode (patch by Jochen Voss (see Debian #224443)).
        + modify c++/cursesf.h to use const in the Enumeration_Field method.
        + remove an ambiguous (actually redundant) method from c++/cursesf.h
        + make $HOME/.terminfo update optional (suggested by Stanislav Ievlev).
        + improve sed script which extracts libtool's version in the
          CF_WITH_LIBTOOL macro.
        + add ifdef'd call to AC_PROG_LIBTOOL to CF_WITH_LIBTOOL macro (to
          simplify local patch for Albert Chin-A-Young)..
        + add $(CXXFLAGS) to link command in c++/Makefile.in (adapted from
          patch by Albert Chin-A-Young)..
        + fix a missing substitution in configure.in for "$target" needed for
          HPUX .so/.sl case.
        + resync CF_XOPEN_SOURCE configure macro with lynx; fixes IRIX64 and
          NetBSD 1.6 conflicts with _XOPEN_SOURCE.
        + make check for stdbool.h more specific, to ensure that including it
          will actually define/declare bool for the configured compiler.
        + rewrite ifdef's in curses.h relating NCURSES_BOOL and bool.  The
          intention of that is to #define NCURSES_BOOL as bool when the
          compiler declares bool, and to #define bool as NCURSES_BOOL when it
          does not (reported by Jim Gifford, Sam Varshavchik, cf: 20031213).

20040110 pre-release
        + change minor version to 4, i.e., ncurses 5.4
        + revised/improved terminfo entries for tvi912b, tvi920b (Benjamin C W
          Sittler).
        + simplified ncurses/base/version.c by defining the result from the
          configure script rather than using sprintf (suggested by Stanislav
          Ievlev).
        + remove obsolete casts from c++/cursesw.h (reported by Stanislav
          Ievlev).
        + modify configure script so that when configuring for termlib, programs
          such as tic are not linked with the upper-level ncurses library
          (suggested by Stanislav Ievlev).
        + move version.c from ncurses/base to ncurses/tinfo to allow linking
          of tic, etc., using libtinfo (suggested by Stanislav Ievlev).

20040103
        + adjust -D's to build ncursesw on OpenBSD.
        + modify CF_PROG_EXT to make OS/2 build with EXEEXT.
        + add pecho_wchar().
        + remove <wctype.h> include from lib_slk_wset.c which is not needed (or
          available) on older platforms.

20031227
        + add -D's to build ncursew on FreeBSD 5.1.
        + modify shared library configuration for FreeBSD 4.x/5.x to add the
          soname information (request by Marc Glisse).
        + modify _nc_read_tic_entry() to not use MAX_ALIAS, but PATH_MAX only
          for limiting the length of a filename in the terminfo database.
        + modify termname() to return the terminal name used by setupterm()
          rather than $TERM, without truncating to 14 characters as documented
          by X/Open (report by Stanislav Ievlev, cf:  970719).
        + re-add definition for _BSD_TYPES, lost in merge (cf: 20031206).

20031220
        + add configure option --with-manpage-format=catonly to address
          behavior of BSDI, allow install of man+cat files on NetBSD, whose
          behavior has diverged by requiring both to be present.
        + remove leading blanks from comment-lines in manlinks.sed script to
          work with Tru64 4.0d.
        + add screen.linux terminfo entry (discussion on mutt-users mailing
          list).

20031213
        + add a check for tic to flag missing backslashes for termcap
          continuation lines.  ncurses reads the whole entry, but termcap
          applications do not.
        + add configure option "--with-manpage-aliases" extending
          "--with-manpage-aliases" to provide the option of generating ".so"
          files rather than symbolic links for manpage aliases.
        + add bool definition in include/curses.h.in for configurations with no
          usable C++ compiler (cf: 20030607).
        + fix pathname of SigAction.h for building with --srcdir (reported by
          Mike Castle).

20031206
        + folded ncurses/base/sigaction.c into includes of ncurses/SigAction.h,
          since that header is used only within ncurses/tty/lib_tstp.c, for
          non-POSIX systems (discussion with Stanislav Ievlev).
        + remove obsolete _nc_outstr() function (report by Stanislav Ievlev
          <inger@altlinux.org>).
        + add test/background.c and test/color_set.c
        + modify color_set() function to work with color pair 0 (report by
          George Andreou <gbandreo@tem.uoc.gr>).
        + add configure option --with-trace, since defining TRACE seems too
          awkward for some cases.
        + remove a call to _nc_free_termtype() from read_termtype(), since the
          corresponding buffer contents were already zeroed by a memset (cf:
          20000101).
        + improve configure check for _XOPEN_SOURCE and related definitions,
          adding special cases for Solaris' __EXTENSIONS__ and FreeBSD's
          __BSD_TYPES (reports by Marc Glisse <marc.glisse@normalesup.org>).
        + small fixes to compile on Solaris and IRIX64 using cc.
        + correct typo in check for pre-POSIX sort options in MKkey_defs.sh
          (cf: 20031101).

20031129
        + modify _nc_gettime() to avoid a problem with arithmetic on unsigned
          values (Philippe Blain).
        + improve the nanosleep() logic in napms() by checking for EINTR and
          restarting (Philippe Blain).
        + correct expression for "%D" in lib_tgoto.c (Juha Jarvi
          <mooz@welho.com>).

20031122
        + add linux-vt terminfo entry (Andrey V Lukyanov <land@long.yar.ru>).
        + allow "\|" escape in terminfo; tic should not warn about this.
        + save the full pathname of the trace-file the first time it is opened,
          to avoid creating it in different directories if the application
          opens and closes it while changing its working directory.
        + modify configure script to provide a non-empty default for
          $BROKEN_LINKER

20031108
        + add DJGPP to special case of DOS-style drive letters potentially
          appearing in TERMCAP environment variable.
        + fix some spelling in comments (reports by Jason McIntyre, Jonathon
          Gray).
        + update config.guess, config.sub

20031101
        + fix a memory leak in error-return from setupterm() (report by
          Stanislav Ievlev <inger@altlinux.org>).
        + use EXEEXT and OBJEXT consistently in makefiles.
        + amend fixes for cross-compiling to use separate executable-suffix
          BUILD_EXEEXT (cf: 20031018).
        + modify MKkey_defs.sh to check for sort utility that does not
          recognize key options, e.g., busybox (report by Peter S Mazinger
          <ps.m@gmx.net>).
        + fix potential out-of-bounds indexing in _nc_infotocap() (found by
          David Krause using some of the new malloc debugging features
          under OpenBSD, patch by Ted Unangst).
        + modify CF_LIB_SUFFIX for Itanium releases of HP-UX, which use a
          ".so" suffix (patch by Jonathan Ward <Jonathan.Ward@hp.com>).

20031025
        + update terminfo for xterm-xfree86 -TD
        + add check for multiple "tc=" clauses in a termcap to tic.
        + check for missing op/oc in tic.
        + correct _nc_resolve_uses() and _nc_merge_entry() to allow infocmp and
          tic to show cancelled capabilities.  These functions were ignoring
          the state of the target entry, which should be untouched if cancelled.
        + correct comment in tack/output.c (Debian #215806).
        + add some null-pointer checks to lib_options.c (report by Michael
          Bienia).
        + regenerated html documentation.
        + correction to tar-copy.sh, remove a trap command that resulted in
          leaving temporary files (cf: 20030510).
        + remove contact/maintainer addresses for Juergen Pfeifer (his request).

20031018
        + updated test/configure to reflect changes for libtool (cf: 20030830).
        + fix several places in tack/pad.c which tested and used the parameter-
          and parameterless strings inconsistently, i.e., in pad_rin(),
          pad_il(), pad_indn() and pad_dl() (Debian #215805).
        + minor fixes for configure script and makefiles to cleanup executables
          generated when cross-compiling for DJGPP.
        + modify infocmp to omit check for $TERM for operations that do not
          require it, e.g., "infocmp -e" used to build fallback list (report by
          Egmont Koblinger).

20031004
        + add terminfo entries for DJGPP.
        + updated note about maintainer in ncurses-intro.html

20030927
        + update terminfo entries for gnome terminal.
        + modify tack to reset colors after each color test, correct a place
          where exit_standout_mode was used instead of exit_attribute_mode.
        + improve tack's bce test by making it set colors other than black
          on white.
        + plug a potential recursion between napms() and _nc_timed_wait()
          (report by Philippe Blain).

20030920
        + add --with-rel-version option to allow workaround to allow making
          libtool on Darwin generate the "same" library names as with the
          --with-shared option.  The Darwin ld program does not work well
          with a zero as the minor-version value (request by Chris Zubrzycki).
        + modify CF_MIXEDCASE_FILENAMES macro to work with cross-compiling.
        + modify tack to allow it to run from fallback terminfo data.
        > patch by Philippe Blain:
        + improve PutRange() by adjusting call to EmitRange() and corresponding
          return-value to not emit unchanged characters on the end of the
          range.
        + improve a check for changed-attribute by exiting a loop when the
          change is found.
        + improve logic in TransformLine(), eliminating a duplicated comparison
          in the clr_bol logic.

20030913
        > patch by Philippe Blain:
        + in ncurses/tty/lib_mvcur.c,
          move the label 'nonlocal' just before the second gettimeofday() to
          be able to compute the diff time when 'goto nonlocal' used.
          Rename 'msec' to 'microsec' in the debug-message.
        + in ncurses/tty/lib_mvcur.c,
          Use _nc_outch() in carriage return/newline movement instead of
          putchar() which goes to stdout.  Move test for xold>0 out of loop.
        + in ncurses/tinfo/setbuf.c,
          Set the flag SP->_buffered at the end of operations when all has been
          successful (typeMalloc can fail).
        + simplify NC_BUFFERED macro by moving check inside _nc_setbuf().

20030906
        + modify configure script to avoid using "head -1", which does not
          work if POSIXLY_CORRECT (sic) is set.
        + modify run_tic.in to avoid using wrong shared libraries when
          cross-compiling (Dan Kegel).

20030830
        + alter configure script help message to make it clearer that
          --with-build-cc does not specify a cross-compiler (suggested by Dan
          Kegel <dank@kegel.com>).
        + modify configure script to accommodate libtool 1.5, as well as add an
          parameter to the "--with-libtool" option which can specify the
          pathname of libtool (report by Chris Zubrzycki).  We note that
          libtool 1.5 has more than one bug in its C++ support, so it is not
          able to install libncurses++, for instance, if $DESTDIR or the option
          --with-install-prefix is used.

20030823
        > patch by Philippe Blain:
        + move assignments to SP->_cursrow, SP->_curscol into online_mvcur().
        + make baudrate computation in delay_output() consistent with the
          assumption in _nc_mvcur_init(), i.e., a byte is 9 bits.

20030816
        + modify logic in waddch_literal() to take into account zh_TW.Big5
          whose multibyte sequences may contain "printable" characters, e.g.,
          a "g" in the sequence "\247g" (Debian #204889, cf: 20030621).
        + improve storage used by _nc_safe_strcpy() by ensuring that the size
          is reset based on the initialization call, in case it were called
          after other strcpy/strcat calls (report by Philippe Blain).
        > patch by Philippe Blain:
        + remove an unused ifdef for REAL_ATTR & WANT_CHAR
        + correct a place where _cup_cost was used rather than _cuu_cost

20030809
        + fix a small memory leak in _nc_free_termtype().
        + close trace-file if trace() is called with a zero parameter.
        + free memory allocated for soft-key strings, in delscreen().
        + fix an allocation size in safe_sprintf.c for the "*" format code.
        + correct safe_sprintf.c to not return a null pointer if the format
          happens to be an empty string.  This applies to the "configure
          --enable-safe-sprintf" option (Redhat #101486).

20030802
        + modify casts used for ABSENT_BOOLEAN and CANCELLED_BOOLEAN (report by
          Daniel Jacobowitz).
        > patch by Philippe Blain:
        + change padding for change_scroll_region to not be proportional to
          the size of the scroll-region.
        + correct error-return in _nc_safe_strcat().

20030726
        + correct limit-checks in _nc_scroll_window() (report and test-case by
          Thomas Graf <graf@dms.at> cf: 20011020).
        + re-order configure checks for _XOPEN_SOURCE to avoid conflict with
          _GNU_SOURCE check.

20030719
        + use clr_eol in preference to blanks for bce terminals, so select and
          paste will have fewer trailing blanks, e.g., when using xterm
          (request by Vincent Lefevre).
        + correct prototype for wunctrl() in manpage.
        + add configure --with-abi-version option (discussion with Charles
          Wilson).
        > cygwin changes from Charles Wilson:
          + aclocal.m4: on cygwin, use autodetected prefix for import
            and static lib, but use "cyg" for DLL.
          + include/ncurses_dll.h: correct the comments to reflect current
            status of cygwin/mingw port.  Fix compiler warning.
          + misc/run_tic.in: ensure that tic.exe can find the uninstalled
            DLL, by adding the lib-directory to the PATH variable.
          + misc/terminfo.src (nxterm|xterm-color): make xterm-color
            primary instead of nxterm, to match XFree86's xterm.terminfo
            usage and to prevent circular links.
            (rxvt): add additional codes from rxvt.org.
            (rxvt-color): new alias
            (rxvt-xpm): new alias
            (rxvt-cygwin): like rxvt, but with special acsc codes.
            (rxvt-cygwin-native): ditto.  rxvt may be run under XWindows, or
            with a "native" MSWin GUI.  Each takes different acsc codes,
            which are both different from the "normal" rxvt's acsc.
            (cygwin): cygwin-in-cmd.exe window.  Lots of fixes.
            (cygwinDBG): ditto.
          + mk-1st.awk: use "cyg" for the DLL prefix, but "lib" for import
            and static libs.

20030712
        + update config.guess, config.sub
        + add triples for configuring shared libraries with the Debian
          GNU/FreeBSD packages (patch by Robert Millan <zeratul2@wanadoo.es>).

20030705
        + modify CF_GCC_WARNINGS so it only applies to gcc, not g++.  Some
          platforms have installed g++ along with the native C compiler, which
          would not accept gcc warning options.
        + add -D_XOPEN_SOURCE=500 when configuring with --enable-widec, to
          get mbstate_t declaration on HPUX 11.11 (report by David Ellement).
        + add _nc_pathlast() to get rid of casts in _nc_basename() calls.
        + correct a sign-extension in wadd_wch() and wecho_wchar() from
          20030628 (report by Tomohiro Kubota).
        + work around omission of btowc() and wctob() from wide-character
          support (sic) in NetBSD 1.6 using mbtowc() and wctomb() (report by
          Gabor Z Papp).
        + add portability note to curs_get_wstr.3x (Debian #199957).

20030628
        + rewrite wadd_wch() and wecho_wchar() to call waddch() and wechochar()
          respectively, to avoid calling waddch_noecho() with wide-character
          data, since that function assumes its input is 8-bit data.
          Similarly, modify waddnwstr() to call wadd_wch().
        + remove logic from waddnstr() which transformed multibyte character
          strings into wide-characters.  Rewrite of waddch_literal() from
          20030621 assumes its input is raw multibyte data rather than wide
          characters (report by Tomohiro Kubota).

20030621
        + write getyx() and related 2-return macros in terms of getcury(),
          getcurx(), etc.
        + modify waddch_literal() in case an application passes bytes of a
          multibyte character directly to waddch().  In this case, waddch()
          must reassemble the bytes into a wide-character (report by Tomohiro
          Kubota <kubota@debian.org>).

20030614
        + modify waddch_literal() in case a multibyte value occupies more than
          two cells.
        + modify PutAttrChar() to compute the number of character cells that
          are used in multibyte values.  This fixes a problem displaying
          double-width characters (report/test by Mitsuru Chinen
          <mchinen@yamato.ibm.com>).
        + add a null-pointer check for result of keyname() in _tracechar()
        + modify _tracechar() to work around glibc sprintf bug.

20030607
        + add a call to setlocale() in cursesmain.cc, making demo display
          properly in a UTF-8 locale.
        + add a fallback definition in curses.priv.h for MB_LEN_MAX (prompted
          by discussion with Gabor Z Papp).
        + use macros NCURSES_ACS() and NCURSES_WACS() to hide cast needed to
          appease -Wchar-subscript with g++ 3.3 (Debian #195732).
        + fix a redefinition of $RANLIB in the configure script when libtool
          is used, which broke configure on Mac OS X (report by Chris Zubrzycki
          <beren@mac.com>).
        + simplify ifdef for bool declaration in curses.h.in (suggested by
          Albert Chin-A-Young).
        + remove configure script check to allow -Wconversion for older
          versions of gcc (suggested by Albert Chin-A-Young).

20030531
        + regenerated html manpages.
        + modify ifdef's in curses.h.in that disabled use of __attribute__()
          for g++, since recent versions implement the cases which ncurses uses
          (Debian #195230).
        + modify _nc_get_token() to handle a case where an entry has no
          description, and capabilities begin on the same line as the entry
          name.
        + fix a typo in ncurses_dll.h reported by gcc 3.3.
        + add an entry for key_defined.3x to man_db.renames.

20030524
        + modify setcchar() to allow converting control characters to complex
          characters (report/test by Mitsuru Chinen <mchinen@yamato.ibm.com>).
        + add tkterm entry -TD
        + modify parse_entry.c to allow a terminfo entry with a leading
          2-character name (report by Don Libes).
        + corrected acsc in screen.teraterm, which requires a PC-style mapping.
        + fix trace statements in read_entry.c to use lseek() rather than
          tell().
        + fix signed/unsigned warnings from Sun's compiler (gcc should give
          these warnings, but it is unpredictable).
        + modify configure script to omit -Winline for gcc 3.3, since that
          feature is broken.
        + modify manlinks.sed to add a few functions that were overlooked since
          they return function pointers:  field_init, field_term, form_init,
          form_term, item_init, item_term, menu_init and menu_term.

20030517
        + prevent recursion in wgetch() via wgetnstr() if the connection cannot
          be switched between cooked/raw modes because it is not a TTY (report
          by Wolfgang Gutjahr <gutw@knapp.com>).
        + change parameter of define_key() and key_defined() to const (prompted
          by Debian #192860).
        + add a check in test/configure for ncurses extensions, since there
          are some older versions, etc., which would not compile with the
          current test programs.
        + corrected demo in test/ncurses.c of wgetn_wstr(), which did not
          convert wchar_t string to multibyte form before printing it.
        + corrections to lib_get_wstr.c:
          + null-terminate buffer passed to setcchar(), which occasionally
            failed.
          + map special characters such as erase- and kill-characters into
            key-codes so those will work as expected even if they are not
            mentioned in the terminfo.
        + modify PUTC() and Charable() macros to make wide-character line
          drawing work for POSIX locale on Linux console (cf: 20021221).

20030510
        + make typography for program options in manpages consistent (report
          by Miloslav Trmac <mitr@volny.cz>).
        + correct dependencies in Ada95/src/Makefile.in, so the builds with
          "--srcdir" work (report by Warren L Dodge).
        + correct missing definition of $(CC) in Ada95/gen/Makefile.in
          (reported by Warren L Dodge <warrend@mdhost.cse.tek.com>).
        + fix typos and whitespace in manpages (patch by Jason McIntyre
          <jmc@prioris.mini.pw.edu.pl>).

20030503
        + fix form_driver() cases for REQ_CLR_EOF, REQ_CLR_EOL, REQ_DEL_CHAR,
          REQ_DEL_PREV and REQ_NEW_LINE, which did not ensure the cursor was at
          the editing position before making modifications.
        + add test/demo_forms and associated test/edit_field.c demos.
        + modify test/configure.in to use test/modules for the list of objects
          to compile rather than using the list of programs.

20030419
        + modify logic of acsc to use the original character if no mapping is
          defined, noting that Solaris does this.
        + modify ncurses 'b' test to avoid using the acs_map[] array since
          20021231 changes it to no longer contain information from the acsc
          string.
        + modify makefile rules in c++, progs, tack and test to ensure that
          the compiler flags (e.g., $CFLAGS or $CCFLAGS) are used in the link
          command (report by Jose Luis Rico Botella <informatica@serpis.com>).
        + modify soft-key initialization to use A_REVERSE if A_STANDOUT would
          not be shown when colors are used, i.e., if ncv#1 is set in the
          terminfo as is done in "screen".

20030412
        + add a test for slk_color(), in ncurses.c
        + fix some issues reported by valgrind in the slk_set() and slk_wset()
          code, from recent rewrite.
        + modify ncurses 'E' test to use show previous label via slk_label(),
          as in 'e' test.
        + modify wide-character versions of NewChar(), NewChar2() macros to
          ensure that the whole struct is initialized.

20030405
        + modify setupterm() to check if the terminfo and terminal-modes have
          already been read.  This ensures that it does not reinvoke
          def_prog_mode() when an application calls more than one function,
          such as tgetent() and initscr() (report by Olaf Buddenhagen).

20030329
        + add 'E' test to ncurses.c, to exercise slk_wset().
        + correct handling of carriage-return in wgetn_wstr(), used in demo of
          slk_wset().
        + first draft of slk_wset() function.

20030322
        + improved warnings in tic when suppressing items to fit in termcap's
          1023-byte limit.
        + built a list in test/README showing which externals are being used
          by either programs in the test-directory or via internal library
          calls.
        + adjust include-options in CF_ETIP_DEFINES to avoid missing
          ncurses_dll.h, fixing special definitions that may be needed for
          etip.h (reported by Greg Schafer <gschafer@zip.com.au>).

20030315
        + minor fixes for cardfile.c, to make it write the updated fields to
          a file when ^W is given.
        + add/use _nc_trace_bufcat() to eliminate some fixed buffer limits in
          trace code.

20030308
        + correct a case in _nc_remove_string(), used by define_key(), to avoid
          infinite loop if the given string happens to be a substring of other
          strings which are assigned to keys (report by John McCutchan).
        + add key_defined() function, to tell which keycode a string is bound
          to (discussion with John McCutchan <ttb@tentacle.dhs.org>).
        + correct keybound(), which reported definitions in the wrong table,
          i.e., the list of definitions which are disabled by keyok().
        + modify demo_keydef.c to show the details it changes, and to check
          for errors.

20030301
        + restructured test/configure script, make it work for libncursesw.
        + add description of link_fieldtype() to manpage (report by
          L Dee Holtsclaw <dee@sunbeltsoft.com>).

20030222
        + corrected ifdef's relating to configure check for wchar_t, etc.
        + if the output is a socket or other non-tty device, use 1 millisecond
          for the cost in mvcur; previously it was 9 milliseconds because the
          baudrate was not known.
        + in _nc_get_tty_mode(), initialize the TTY buffer on error, since
          glibc copies uninitialized data in that case, as noted by valgrind.
        + modify tput to use the same parameter analysis as tparm() does, to
          provide for user-defined strings, e.g., for xterm title, a
          corresponding capability might be
                title=\E]2;%p1%s^G,
        + modify MKlib_gen.sh to avoid passing "#" tokens through the C
          preprocessor.  This works around Mac OS X's preprocessor, which
          insists on adding a blank on each side of the token (report/analysis
          by Kevin Murphy <murphy@genome.chop.edu>).

20030215
        + add configure check for wchar_t and wint_t types, rather than rely
          on preprocessor definitions.  Also work around for gcc fixinclude
          bug which creates a shadow copy of curses.h if it sees these symbols
          apparently typedef'd.
        + if database is disabled, do not generate run_tic.sh
        + minor fixes for memory-leak checking when termcap is read.

20030208
        + add checking in tic for incomplete line-drawing character mapping.
        + updated configure script to reflect fix for AC_PROG_GCC_TRADITIONAL,
          which is broken in autoconf 2.5x for Mac OS X 10.2.3 (report by
          Gerben Wierda <Sherlock@rna.nl>).
        + make return value from _nc_printf_string() consistent.  Before,
          depending on whether --enable-safe-sprintf was used, it might not be
          cached for reallocating.

20030201
        + minor fixes for memory-leak checking in lib_tparm.c, hardscroll.c
        + correct a potentially-uninitialized value if _read_termtype() does
          not read as much data as expected (report by Wolfgang Rohdewald
          <wr6@uni.de>).
        + correct several places where the aclocal.m4 macros relied on cache
          variable names which were incompatible (as usual) between autoconf
          2.13 and 2.5x, causing the test for broken-linker to give incorrect
          results (reports by Gerben Wierda <Sherlock@rna.nl> and Thomas Esser
          <te@dbs.uni-hannover.de>).
        + do not try to open gpm mouse driver if standard output is not a tty;
          the gpm library does not make this check (bug report for dialog
          by David Oliveira <davidoliveira@develop.prozone.ws>).

20030125
        + modified emx.src to correspond more closely to terminfo.src, added
          emx-base to the latter -TD
        + add configure option for FreeBSD sysmouse, --with-sysmouse, and
          implement support for that in lib_mouse.c, lib_getch.c

20030118
        + revert 20030105 change to can_clear_with(), does not work for the
          case where the update is made on cells which are blanks with
          attributes, e.g., reverse.
        + improve ifdef's to guard against redefinition of wchar_t and wint_t
          in curses.h (report by Urs Jansen).

20030111
        + improve mvcur() by checking if it is safe to move when video
          attributes are set (msgr), and if not, reset/restore attributes
          within that function rather than doing it separately in the GoTo()
          function in tty_update.c (suggested by Philippe Blain).
        + add a message in run_tic.in to explain more clearly what does not
          work when attempting to create a symbolic link for /usr/lib/terminfo
          on OS/2 and other platforms with no symbolic links (report by John
          Polterak).
        + change several sed scripts to avoid using "\+" since it is not a BRE
          (basic regular expression).  One instance caused terminfo.5 to be
          misformatted on FreeBSD (report by Kazuo Horikawa
          <horikawa@FreeBSD.org> (see FreeBSD docs/46709)).
        + correct misspelled 'wint_t' in curs_get_wch.3x (Michael Elkins).

20030105
        + improve description of terminfo operators, especially static/dynamic
          variables (comments by Mark I Manning IV <mark4th@earthlink.net>).
        + demonstrate use of FIELDTYPE by modifying test/ncurses 'r' test to
          use the predefined TYPE_ALPHA field-type, and by defining a
          specialized type for the middle initial/name.
        + fix MKterminfo.sh, another workaround for POSIXLY_CORRECT misfeature
          of sed 4.0
        > patch by Philippe Blain:
        + optimize can_clear_with() a little by testing first if the parameter
          is indeed a "blank".
        + simplify ClrBottom() a little by allowing it to use clr_eos to clear
          sections as small as one line.
        + improve ClrToEOL() by checking if clr_eos is available before trying
          to use it.
        + use tputs() rather than putp() in a few cases in tty_update.c since
          the corresponding delays are proportional to the number of lines
          affected: repeat_char, clr_eos, change_scroll_region.

20021231
        + rewrite of lib_acs.c conflicts with copying of SCREEN acs_map to/from
          global acs_map[] array; removed the lines that did the copying.

20021228
        + change some overlooked tputs() calls in scrolling code to use putp()
          (report by Philippe Blain).
        + modify lib_getch.c to avoid recursion via wgetnstr() when the input
          is not a tty and consequently mode-changes do not work (report by
          <R.Chamberlin@querix.com>).
        + rewrote lib_acs.c to allow PutAttrChar() to decide how to render
          alternate-characters, i.e., to work with Linux console and UTF-8
          locale.
        + correct line/column reference in adjust_window(), needed to make
          special windows such as curscr track properly when resizing (report
          by Lucas Gonze <lgonze@panix.com>).
        > patch by Philippe Blain:
        + correct the value used for blank in ClrBottom() (broken in 20000708).
        + correct an off-by-one in GoTo() parameter in _nc_scrolln().

20021221
        + change several tputs() calls in scrolling code to use putp(), to
          enable padding which may be needed for some terminals (patch by
          Philippe Blain).
        + use '%' as sed substitute delimiter in run_tic script to avoid
          problems with pathname delimiters such as ':' and '@' (report by John
          Polterak).
        + implement a workaround so that line-drawing works with screen's
          crippled UTF-8 support (tested with 3.9.13).  This only works with
          the wide-character support (--enable-widec); the normal library will
          simply suppress line-drawing when running in a UTF-8 locale in screen.

20021214
        + allow BUILD_CC and related configure script variables to be
          overridden from the environment.
        + make build-tools variables in ncurses/Makefile.in consistent with
          the configure script variables (report by Maciej W Rozycki).
        + modify ncurses/modules to allow
                configure --disable-leaks --disable-ext-funcs
          to build (report by Gary Samuelson).
        + fix a few places in configure.in which lacked quotes (report by
          Gary Samuelson <gary.samuelson@verizon.com>).
        + correct handling of multibyte characters in waddch_literal() which
          force wrapping because they are started too late on the line (report
          by Sam Varshavchik).
        + small fix for CF_GNAT_VERSION to ignore the help-message which
          gnatmake adds to its version-message.
        > Maciej W Rozycki <macro@ds2.pg.gda.pl>:
        + use AC_CHECK_TOOL to get proper values for AR and LD for cross
          compiling.
        + use $cross_compiling variable in configure script rather than
          comparing $host_alias and $target alias, since "host" is
          traditionally misused in autoconf to refer to the target platform.
        + change configure --help message to use "build" rather than "host"
          when referring to the --with-build-XXX options.

20021206
        + modify CF_GNAT_VERSION to print gnatmake's version, and to allow for
          possible gnat versions such as 3.2 (report by Chris Lingard
          <chris@stockwith.co.uk>).
        + modify #define's for CKILL and other default control characters in
          tset to use the system's default values if they are defined.
        + correct interchanged defaults for kill and interrupt characters
          in tset, which caused it to report unnecessarily (Debian #171583).
        + repair check for missing C++ compiler, which is broken in autoconf
          2.5x by hardcoding it to g++ (report by Martin Mokrejs).
        + update config.guess, config.sub (2002-11-30)
        + modify configure script to skip --with-shared, etc., when the
          --with-libtool option is given, since they would be ignored anyway.
        + fix to allow "configure --with-libtool --with-termlib" to build.
        + modify configure script to show version number of libtool, to help
          with bug reports.  libtool still gets confused if the installed
          ncurses libraries are old, since it ignores the -L options at some
          point (tested with libtool 1.3.3 and 1.4.3).
        + reorder configure script's updating of $CPPFLAGS and $CFLAGS to
          prevent -I options in the user's environment from introducing
          conflicts with the build -I options (may be related to reports by
          Patrick Ash and George Goffe).
        + rename test/define_key.c to test/demo_defkey.c, test/keyok.c to
          test/demo_keyok.c to allow building these with libtool.

20021123
        + add example program test/define_key.c for define_key().
        + add example program test/keyok.c for keyok().
        + add example program test/ins_wide.c for wins_wch() and wins_wstr().
        + modify wins_wch() and wins_wstr() to interpret tabs by using the
          winsch() internal function.
        + modify setcchar() to allow for wchar_t input strings that have
          more than one spacing character.

20021116
        + fix a boundary check in lib_insch.c (patch by Philippe Blain).
        + change type for *printw functions from NCURSES_CONST to const
          (prompted by comment by Pedro Palhoto Matos <plpm@mega.ist.utl.pt>,
          but really from a note on X/Open's website stating that either is
          acceptable, and the latter will be used in a future revision).
        + add xterm-1002, xterm-1003 terminfo entries to demonstrate changes in
          lib_mouse.c (20021026) -TD
        + add screen-bce, screen-s entries from screen 3.9.13 (report by
          Adam Lazur <zal@debian.org>) -TD
        + add mterm terminfo entries -TD

20021109
        + split-out useful fragments in terminfo for vt100 and vt220 numeric
          keypad, i.e., vt100+keypad, vt100+pfkeys, vt100+fnkeys and
          vt220+keypad.  The last as embedded in various entries had ka3 and
          kb2 interchanged (report/discussion with Leonard den Ottolander
          <leonardjo@hetnet.nl>).
        + add check in tic for keypads consistent with vt100 layout.
        + improve checks in tic for color capabilities

20021102
        + check for missing/empty/illegal terminfo name in _nc_read_entry()
          (report by Martin Mokrejs, where $TERM was set to an empty string).
        + rewrote lib_insch.c, combining it with lib_insstr.c so both handle
          tab and other control characters consistently (report by Philippe
          Blain).
        + remove an #undef for KEY_EVENT from curses.tail used in the
          experimental NCURSES_WGETCH_EVENTS feature.  The #undef confuses
          dpkg's build script (Debian #165897).
        + fix MKlib_gen.sh, working around the ironically named POSIXLY_CORRECT
          feature of GNU sed 4.0 (reported by Ervin Nemeth <airwin@inf.bme.hu>).

20021026
        + implement logic in lib_mouse.c to handle position reports which are
          generated when XFree86 xterm is initialized with private modes 1002
          or 1003.  These are returned to the application as the
          REPORT_MOUSE_POSITION mask, which was not implemented.  Tested both
          with ncurses 'a' menu (prompted by discussion with Larry Riedel
          <Larry@Riedel.org>).
        + modify lib_mouse.c to look for "XM" terminfo string, which allows
          one to override the escape sequence used to enable/disable mouse
          mode.  In particular this works for XFree86 xterm private modes
          1002 and 1003.  If "XM" is missing (note that this is an extended
          name), lib_mouse uses the conventional private mode 1000.
        + correct NOT_LOCAL() macro in lib_mvcur.c to refer to screen_columns
          where it used screen_lines (report by Philippe Blain).
        + correct makefile rules for the case when both --with-libtool and
          --with-gpm are given (report by Mr E_T <troll@logi.net.au>).
        + add note to terminfo manpage regarding the differences between
          setaf/setab and setf/setb capabilities (report by Pavel Roskin).

20021019
        + remove redundant initialization of TABSIZE in newterm(), since it is
          already done in setupterm() (report by Philippe Blain).
        + add test/inserts.c, to test winnstr() and winsch().
        + replace 'sort' in dist.mk with script that sets locale to POSIX.
        + update URLs in announce.html.in (patch by Frederic L W Meunier).
        + remove glibc add-on files, which are no longer needed (report by
          Frederic L W Meunier).

20021012 5.3 release for upload to ftp.gnu.org
        + modify ifdef's in etip.h.in to allow the etip.h header to compile
          with gcc 3.2 (patch by Dimitar Zhekov <jimmy@is-vn.bg>).
        + add logic to setupterm() to make it like initscr() and newterm(),
          by checking for $NCURSES_TRACE environment variable and enabling
          the debug trace in that case.
        + modify setupterm() to ensure that it initializes the baudrate, for
          applications such as tput (report by Frank Henigman).
        + modify definition of bits used for command-line and library debug
          traces to avoid overlap, using new definition TRACE_SHIFT to relate
          the two.
        + document tput's interpretation of parameterized strings according to
          whether parameters are given, etc. (discussion with Robert De Bath).

20021005 pre-release
        + correct winnwstr() to account for non-character cells generated when
          a double-width character is added (report by Michael Bienia
          <michael@vorlon.ping.de>).
        + modify _nc_viswbuf2n() to provide better results using wctomb().
        + correct logic in _nc_varargs() which broke tracing of parameters for
          formats such as "%.*s".
        + correct scale factor in linux-c and linux-c-nc terminfo entries
          (report Floyd Davidson).
        + change tic -A option to -t, add the same option to infocmp for
          consistency.
        + correct "%c" implementation in lib_tparm.c, which did not map a null
          character to a 128 (cf: 980620) (patch by Frank Henigman
          <fjhenigman@mud.cgl.uwaterloo.ca>).

20020928 pre-release
        + modify MKkey_defs.sh to check for POSIX sort -k option, use that if
          it is found, to accommodate newer utility which dropped the
          compatibility support for +number options (reported by Andrey A
          Chernov).
        + modify linux terminfo entry to use color palette feature from
          linux-c-nc entry (comments by Tomasz Wasiak and Floyd Davidson).
        + restore original color definitions in endwin() if init_color() was
          used, and resume those colors on the next doupdate() or refresh()
          (report by Tomasz Wasiak <tjwasiak@komputom.com.pl>).
        + improve debug-traces by modifying MKlib_gen.sh to generate calls
          to returnBool() and returnAttr().
        + add/use _nc_visbufn() and _nc_viswbufn() to limit the debug trace
          of waddnstr() and similar functions to match the parameters as used.
        + add/use _nc_retrace_bool() and _nc_retrace_unsigned().
        + correct type used by _nc_retrace_chtype().
        + add debug traces to some functions in lib_mouse.c
        + modify lib_addch.c to handle non-spacing characters.
        + correct parameter of RemAttr() in lib_bkgd.c, which caused the c++
          demo's boxes to lose the A_ALTCHARSET flag (broken in 20020629).
        + correct width computed in _tracedump(), which did not account for
          the attributes (broken in 20010602).
        + modify test/tracemunch to replace addresses for windows other than
          curscr, newscr and stdscr with window0, window1, etc.

20020921 pre-release
        + redid fix for edit_man.sed path.
        + workaround for Cygwin bug which makes subprocess writes to stdout
          result in core dump.
        + documented getbegx(), etc.
        + minor fixes to configure script to use '%' consistently as a sed
          delimiter rather than '@'.
        > patch by Philippe Blain:
        + add check in lib_overlay.c to ensure that the windows to be merged
          actually overlap, and in copywin(), limit the area to be touched
          to the lines given for the destination window.

20020914 pre-release
        + modified curses.h so that if the wide-character version is installed
          overwriting /usr/include/curses.h, and if it relied on libutf8.h,
          then applications that use that header for wide-character support
          must define HAVE_LIBUTF8_H.
        + modify putwin(), getwin() and dupwin() to allow them to operate on
          pads (request by Philippe Blain).
        + correct attribute-merging in wborder(), broken in 20020216 (report
          by Tomasz Wasiak <tjwasiak@grubasek.komputom.com.pl>).
        > patch by Philippe Blain:
        + corrected pop-counts in tparam_internal() to '!' and '~' cases.
        + use sizeof(NCURSES_CH_T) in one place that used sizeof(chtype).
        + remove some unused variables from mvcur test-driver.

20020907 pre-release
        + change configure script to allow install of widec-character
          (ncursesw) headers to overwrite normal (ncurses) headers, since the
          latter is a compatible subset of the former.
        + fix path of edit_man.sed in configure script, needed to regenerate
          html manpages on Debian.
        + fix mismatched enums in vsscanf.c, which caused warning on Solaris.
        + update README.emx to reflect current patch used for autoconf.
        + change web- and ftp-site to invisible-island.net
        > patch by Philippe Blain:
        + change case for 'P' in tparam_internal() to indicate that it pops
          a variable from the stack.
        + correct sense of precision and width in parse_format(), to avoid
          confusion.
        + modify lib_tparm.c, absorb really_get_space() into get_space().
        + modify getwin() and dupwin() to copy the _notimeout, _idlok and
          _idcok window fields.
        + better fix for _nc_set_type(), using typeMalloc().

20020901 pre-release
        + change minor version to 3, i.e., ncurses 5.3
        + update config.guess, config.sub
        + retest build with each configure option; minor ifdef fixes.
        + make keyname() return a null pointer rather than "UNKNOWN STRING" to
          match XSI.
        + modify handling of wide line-drawing character functions to use the
          normal line-drawing characters when not in UTF-8 locale.
        + add check/fix to comp_parse.c to suppress warning about missing acsc
          string.  This happens in configurations where raw termcap information
          is processed; tic already does this and other checks.
        + modify tic's check for ich/ich1 versus rmir/smir to only warn about
          ich1, to match xterm patch #70 notes.
        + moved information for ripped-off lines into SCREEN struct to allow
          use in resizeterm().
        + add experimental wgetch_events(), ifdef'd with NCURSES_WGETCH_EVENTS
          (adapted from patch by Ilya Zakharevich - see ncurses/README.IZ).
        + amend check in kgetch() from 20020824 to look only for function-keys,
          otherwise escape sequences are not resolved properly.
        > patch by Philippe Blain:
        + removed redundant assignment to SP->_checkfd from newterm().
        + check return-value of setupterm() in restartterm().
        + use sizeof(NCURSES_CH_T) in a few places that used sizeof(chtype).
        + prevent dupwin() from duplicating a pad.
        + prevent putwin() from writing a pad.
        + use typeRealloc() or typeMalloc() in preference to direct calls on
          _nc_doalloc().

20020824
        + add a check in kgetch() for cooked characters in the fifo to avoid
          calling fifo_push() when a KEY_RESIZE is available (report/analysis
          by Sam Varshavchik <mrsam@courier-mta.com>).
        + fix an overlooked case for Redhat #68199 (Philippe Blain).
        + ensure clearerr() is called before using ferror() e.g., in
          lib_screen.c (report by Philippe Blain).

20020817
        + modify lib_screen.c and lib_newwin.c to maintain the SCREEN-specific
          pointers for curscr/stdscr/newscr when scr_save() and scr_restore()
          modify the global curscr/stdscr/newscr variables.  Fixes Redhat
          #68199.
        + add checks for null pointer in calls to tparm() and tgoto() based on
          FreeBSD bug report.  If ncurses were built with termcap support, and
          the first call to tgoto() were a zero-length string, the result would
          be a null pointer, which was not handled properly.
        + correct a typo in terminfo.head, which gave the octal code for colon
          rather than comma.
        + remove the "tic -u" option from 20020810, since it did not account
          for nested "tc=" clauses, and when that was addressed, was still
          unsatisfactory.

20020810
        + add tic -A option to suppress capabilities which are commented out
          when translating to termcap.
        + add tic -u option to provide older behavior of "tc=" clauses.
        + modified tic to expand all but the final "tc=" clause in a termcap
          entry, to accommodate termcap libraries which do not handle multiple
          tc clauses.
        + correct typo in curs_inopts.3x regarding CS8/CS7 usage (report by
          Philippe Blain).
        + remove a couple of redundant uses of A_ATTRIBUTES in expressions
          using AttrOf(), which already incorporates that mask (report by
          Philippe Blain).
        + document TABSIZE variable.
        + add NCURSES_ASSUMED_COLORS environment variable, to allow users to
          override compiled-in default black-on-white assumption used in
          assume_default_colors().
        + correct an off-by-one comparison against max_colors in COLORFGBG
          logic.
        + correct a use of uninitialized memory found by valgrind (reported by
          Olaf Buddenhagen <olafBuddenhagen@web.de>).
        + modified wresize() to ensure that a failed realloc will not corrupt
          the window structure, and to make subwindows fit within the resized
          window (completes Debian #87678, Debian #101699)

20020803
        + fix an off-by-one in lib_pad.c check for limits of pad (patch by
          Philippe Blain).
        + revise logic for BeOS in lib_twait.c altered in 20011013 to restore
          logic used by lib_getch.c's support for GPM or EMX mouse (report by
          Philippe Blain)
        + remove NCURSES_CONST from several prototypes in curses.wide, to make
          the --enable-const --enable-widec configure options to work together
          (report by George Goffe <grgoffe@yahoo.com>).

20020727
        + finish no-leak checking in cardfile.c, using this for testing changes
          to resizeterm().
        + simplify _nc_freeall() using delscreen().

20020720
        + check error-return from _nc_set_tty_mode() in _nc_initscr() and
          reset_prog_mode() (report/patch by Philippe Blain).
        + regenerate configure using patch for autoconf 2.52, to address
          problem with identifying C++ bool type.
        + correct/improve logic to produce an exit status for errors in tput,
          which did not exit with an error when told to put a string not in the
          current terminfo entry (report by David Gomez <david@pleyades.net>).
        + modify configure script AC_OUTPUT() call to work around defect in
          autoconf 2.52 which adds an ifdef'd include to the generated
          configure definitions.
        + remove fstat() check from scr_init(), which also fixes a missing
          include for <sys/stat.h> from 20020713 (reported by David Ellement,
          fix suggested by Philippe Blain).
        + update curs_scanw.3x manpage to note that XSI curses differs from
          SVr4 curses: return-values are incompatible.
        + correct several prototypes in manpages which used const
          inconsistently with the curses.h file, and removed spurious const's
          in a few places from curses.h, e.g., for wbkgd() (report by Glenn
          Maynard <glenn@zewt.org>).
        + change internal type used by tparm() to long, to work with LP64 model.
        + modify nc_alloc.h to allow building with g++, for testing.

20020713
        + add resize-handling to cardfile.c test program.
        + altered resizeterm() to avoid having it fail when a child window
          cannot be resized because it would be larger than its parent.  (More
          work must be done on this, but it works well enough to integrate).
        + improve a limit-check in lib_refresh.c
        + remove check in lib_screen.c relating dumptime to file's modification
          times, since that would not necessarily work for remotely mounted
          filesystems.
        + modify lrtest to simplify debugging changes to resizeterm, e.g.,
          t/T commands to enable/disable tracing.
        + updated status of multibyte support in TO-DO.
        + update contact info in source-files (patch by Juergen Pfeifer).

20020706
        + add Caps.hpux11, as an example.
        + modify version_filter(), used to implement -R option for tic and
          infocmp, to use computed array offsets based on the Caps.* file which
          is actually configured, rather than constants which correspond to
          the Caps file.
        + reorganized lib_raw.c to avoid updating SP and cur_term state if the
          functions fail (reported by Philippe Blain).
        + add -Wundef to gcc warnings, adjust a few ifdef's to accommodate gcc.

20020629
        + correct parameters to setcchar() in ncurses.c (cf: 20020406).
        + set locale in most test programs (view.c and ncurses.c were the
          only ones).
        + add configure option --with-build-cppflags (report by Maksim A
          Nikulin <M.A.Nikulin@inp.nsk.su>).
        + correct a typo in wide-character logic for lib_bkgnd.c (Philippe
          Blain).
        + modify lib_wacs.c to not cancel the acsc, smacs, rmacs strings when
          in UTF-8 locale.  Wide-character functions use Unicode values, while
          narrow-character functions use the terminfo data.
        + fix a couple of places in Ada95/samples which did not compile with
          gnat 3.14
        + modify mkinstalldirs so the DOS-pathname case is locale-independent.
        + fix locale problem in MKlib_gen.sh by forcing related variables to
          POSIX (C), using same approach as autoconf (set variables only if
          they were set before).  Update MKterminfo.sh and MKtermsort.sh to
          match.

20020622
        + add charset to generated html.
        + add mvterm entry, adapted from a FreeBSD bug-report by Daniel Rudy
          <dcrudy@pacbell.net> -TD
        + add rxvt-16color, ibm+16color entries -TD
        + modify check in --disable-overwrite option so that it is used by
          default unless the --prefix/$prefix value is not /usr, in attempt to
          work around packagers, e.g., for Sun's freeware, who do not read the
          INSTALL notes.

20020615
        + modify wgetch() to allow returning ungetch'd KEY_RESIZE as a function
          key code in get_wch().
        + extended resize-handling in test/ncurses 'a' menu to the entire
          stack of windows created with 'w' commands.
        + improve $COLORFGBG feature by interpreting an out-of-range color
          value as an SGR 39 or 49, for foreground/background respectively.
        + correct a typo in configure --enable-colorfgbg option, and move it
          to the experimental section (cf: 20011208).

20020601
        + add logic to dump_entry.c to remove function-key definitions that do
          not fit into the 1023-byte limit for generated termcaps.  This makes
          hds200 fit.
        + more improvements to tic's warnings, including logic to ignore
          differences between delay values in sgr strings.
        + move definition of KEY_RESIZE into MKkeydefs.sh script, to
          accommodate Caps.osf1r5 which introduced a conflicting definition.

20020525
        + add simple resize-handling in test/ncurses.c 'a' menu.
        + fixes in keyname() and _tracechar() to handle negative values.
        + make tic's warnings about mismatches in sgr strings easier to follow.
        + correct tic checks for number of parameters in smgbp and smglp.
        + improve scoansi terminfo entry, and add scoansi-new entry -TD
        + add pcvt25-color terminfo entry -TD
        + add kf13-kf48 strings to cons25w terminfo entry (reported by Stephen
          Hurd <deuce@lordlegacy.org> in newsgroup lucky.freebsd.bugs) -TD
        + add entrypoint _nc_trace_ttymode(), use this to distinguish the
          Ottyb and Nttyb members of terminal (aka cur_term), for tracing.

20020523
        + correct and simplify logic for lib_pad.c change in 20020518 (reported
          by Mike Castle).

20020518
        + fix lib_pad.c for case of drawing a double-width character which
          falls off the left margin of the pad (patch by Kriang Lerdsuwanakij
          <lerdsuwa@users.sourceforge.net>)
        + modify configure script to work around broken gcc 3.1 "--version"
          option, which adds unnecessary trash to the requested information.
        + adjust ifdef's in case SIGWINCH is not defined, e.g., with DJGPP
          (reported by Ben Decker <deckerben@freenet.de>).

20020511
        + implement vid_puts(), vid_attr(), term_attrs() based on the narrow-
          character versions as well.
        + implement erasewchar(), killwchar() based on erasechar() and
          killchar().
        + modify erasechar() and killchar() to return ERR if the value was
          VDISABLE.
        + correct a bug in wresize() in handling subwindows (based on patch by
          Roger Gammans <rgammans@computer-surgery.co.uk>, report by Scott Beck
          <scott@gossamer-threads.com>).
        + improve test/tclock.c by making the second-hand update more often
          if gettimeofday() is available.

20020429
        + workaround for Solaris sed with MKlib_gen.sh (reported by Andy
          Tsouladze <andyt@mypoints.com>).

20020427
        + correct return-value from getcchar(), making it consistent with
          Solaris and Tru64.
        + reorder loops that generate makefile rules for different models vs
          subsets so configure --with-termlib works again.  This was broken by
          logic added to avoid duplicate rules in changes to accommodate cygwin
          dll's (reported by George.R.Goffe@seagate.com).
        + update config.guess, config.sub

20020421
        + modify ifdef's in write_entry.c to allow use of symbolic links on
          platforms with no hard links, e.g., BeOS.
        + modify a few includes to allow compile with BeOS, which has stdbool.h
          with a conflicting definition for 'bool' versus its OS.h definition.
        + amend MKlib_gen.sh to work with gawk, which defines 'func' as an
          alias for 'function'.

20020420
        + correct form of prototype for ripoffline().
        + modify MKlib_gen.sh to test that all functions marked as implemented
          can be linked.

20020413
        + add manpages: curs_get_wstr.3x, curs_in_wchstr.3x
        + implement wgetn_wstr().
        + implement win_wchnstr().
        + remove redefinition of unget_wch() in lib_gen.c (reported by
          Jungshik Shin <jshin@jtan.com>).

20020406
        + modified several of the test programs to allow them to compile with
          vendor curses implementations, e.g., Solaris, AIX -TD

20020323
        + modified test/configure to allow configuring against ncursesw.
        + change WACS_xxx definition to use address, to work like Tru64 curses.

20020317
        + add 'e' and 'm' toggles to 'a', 'A' tests in ncurses.c to demonstrate
          effect of echo/noecho and meta modes.
        + add 'A' test to ncurses.c to demonstrate wget_wch() and related
          functions.
        + add manpage: curs_get_wch.3x
        + implement unget_wch().
        + implement wget_wch().

20020310
        + regenerated html manpages.
        + add manpages: curs_in_wch.3x, curs_ins_wch.3x, curs_ins_wstr.3x
        + implement wins_wch().
        + implement win_wch().
        + implement wins_nwstr(), wins_wstr().

20020309
        + add manpages: curs_addwstr.3x, curs_winwstr.3x
        + implement winnwstr(), winwstr().

20020223
        + add manpages: curs_add_wchstr.3x, curs_bkgrnd.3x
        + document wunctrl, key_name.
        + implement key_name().
        + remove const's in lib_box.c incorrectly leftover after splitting off
          lib_box_set.c
        + update llib-lncurses, llib-ncursesw, fix configure script related to
          these.

20020218
        + remove quotes on "SYNOPSIS" in man/curs_box_set.3x, which resulted
          in spurious symlinks on install.

20020216
        + implement whline_set(), wvline_set(), add manpage curs_border_set.
        + add subtest 'b' to 'F' and 'f' in ncurses.c to demonstrate use of
          box() and box_set() functions.
        + add subtest 'u' to 'F' in ncurses.c, to demonstrate use of addstr()
          given UTF-8 string equivalents of WACS_xxx symbols.
        + minor fixes to several manpages based on groff -ww output.
        + add descriptions of external variables of termcap interface to
          the manpage (report by Bruce Evans <bde@zeta.org.au>).
        > patches by Bernhard Rosenkraenzer:
        + correct configure option --with-bool, which was executed as
          --with-ospeed.
        + add quotes for parameters of --with-bool and --with-ospeed configure
          options.
        > patch by Sven Verdoolaege (report by Gerhard Haering
          <haering_linux@gmx.de>):
        + correct typos in definitions of several wide-character macros:
          waddwstr, wgetbkgrnd, mvaddwstr, mvwadd_wchnstr, mvwadd_wchnstr,
          mvwaddwstr.
        + pass $(CPPFLAGS) to MKlib_gen.sh, thereby fixing a missing definition
          of _XOPEN_SOURCE_EXTENDED, e.g., on Solaris

20020209
        + implement wide-acs characters for UTF-8 locales.  When in UTF-8
          locale, ignore narrow version of acs.  Add 'F' test to test/ncurses.c
          to demonstrate.
        + correct prototype in keybound manpage (noted from a Debian mailing
          list item).

20020202
        + add several cases to the wscanw() example in testcurs.c, showing the
          format.
        + implement a simple vsscanf() fallback function which uses the %n
          conversion to help parse the input data (prompted by discussion with
          Albert Chin-A-Young).
        + modify mk-1st.awk and test/Makefile.in to add $(LDFLAGS) when making
          shared libraries, and to use $(CFLAGS) when linking test programs
          (patch by Albert Chin-A-Young).
        + add a call to _nc_keypad() in keypad() to accommodate applications
          such as nvi, which use curses for output but not for input (fixes
          Debian #131263, cf: 20011215).
        + add entrypoints to resizeterm.c which provide better control over the
          process:  is_term_resized() and resize_term().  The latter restores
          the original design of resizeterm() before KEY_RESIZE was added in
          970906.  Do this to accommodate 20010922 changes to view.c, but allow
          for programs with their own sigwinch handler, such as lynx (reported
          by Russell Ruby <russ@math.orst.edu>).

20020127
        + fix a typo in change to mk-1st.awk, which broke the shared-library
          makefile rules (reported by Martin Mokrejs).

20020126
        + update config.guess, config.sub
        + finish changes needed to build dll's on cygwin.
        + fix a typo in mvwchat() macro (reported by Cy <yam@homerow.net).

20020119
        + add case in lib_baudrate.c for B921600 (patch by Andrey A Chernov).
        + correct missing sed-editing stage in manpage installs which is used
          to rename manpages, broken in 20010324 fix for Debian #89939 (Debian
          #78866).
        + remove -L$(libdir) from linker flags, probably not needed any more
          since HPUX is handled properly (reported by Niibe Yutaka
          <gniibe@m17n.org>).
        + add configure check for mbstate_t, needed for wide-character
          configuration.  On some platforms we must include <wchar.h> to
          define this (reported by Daniel Jacobowitz).
        + incorporate some of the changes needed to build dll's on cygwin.

20020112a
        + workaround for awk did not work with mawk, adjusted shell script.

20020112
        + add Caps.osf1r5, as an example.
        + modify behavior of can_clear_with() so that if an application is
          running in a non-bce terminals with default colors enabled, it
          returns true, allowing the user to select/paste text without picking
          up extraneous trailing blanks (adapted from patch by Daniel
          Jacobowitz <dmj+@andrew.cmu.edu>).
        + modify generated curses.h to ifdef-out prototypes for extensions if
          they are disabled, and to define curses_version() as a string in that
          case.  This is needed to make the programs such as tic build in that
          configuration.
        + modified generated headers.sh to remove a gzip'd version of the
          target file if it exists, in case non-gzip'd manpages are installed
          into a directory where gzip'd ones exist.  In that case, the latter
          would be found.
        + corrected a redundant initialization of signal handlers from 20010922
          changes.
        + clarified bug-reporting address in terminfo.src (report by John H
          DuBois III <spcecdt@armory.com>).
        > several fixes from Robert Joop:
        + do not use "-v" option of awk in MKkey_defs.sh because it does not
          work with SunOS nawk.
        + modify definitions for libutf8 in curses.h to avoid redefinition
          warnings for mblen
        + quoted references to compiler in shell command in misc/Makefile, in
          case it uses multiple tokens.

20011229
        + restore special case from 20010922 changes to omit SA_RESTART when
          setting up SIGWINCH handler, which is needed to allow wgetch() to be
          interrupted by that signal.
        + updated configure macro CF_WITH_PATHLIST, to omit some double quotes
          not needed with autoconf 2.52
        + revert configure script to autoconf 2.13 patched with
                autoconf-2.13-19990117.patch.gz (or later)
          from
                ftp://invisible-island.net/autoconf/
          because autoconf 2.52 macro AC_PROG_AWK does not work on HPUX 11.0
          (report by David Ellement <ellement@sdd.hp.com>).  This also fixes a
          different problem configuring with Mac OS X (reported by Marc Smith
          <marc.a.smith@home.com>).

20011222
        + modify include/edit_cfg.h to eliminate BROKEN_LINKER symbol from
          term.h
        + move prototype for _nc_vsscanf() into curses.h.in to omit
          HAVE_VSSCANF symbol from curses.h, which was dependent upon the
          ncurses_cfg.h file which is not installed.
        + use ACS_LEN rather than SIZEOF(acs_map) in trace code of lib_acs.c,
          to work with broken linker configuration, e.g., cygwin (report by
          Robert Joop <rj@rainbow.in-berlin.de>).
        + make napms() call _nc_timed_wait() rather than poll() or select(),
          to work around broken implementations of these on cygwin.

20011218
        + drop configure macro CF_WIDEC_SHIFT, since that was rendered obsolete
          by Sven Verdoolaege's rewrite of wide-character support.  This makes
          libncursesw incompatible again, but makes the header files almost the
          same as in the narrow-character configuration.
        + simplify definitions that combine wide/narrow versions of bkgd, etc.,
          to eliminate differences between the wide/narrow versions of curses.h
        + correct typo in configure macro CF_FUNC_VSSCANF
        + correct location of call to _nc_keypad() from 20011215 changes which
          prevented keypad() from being disabled (reported by Lars Hecking).

20011215
        + rewrote ncurses 'a' test to exercise wgetch() and keypad() functions
          better, e.g., by adding a 'w' command to create new windows which
          may have different keypad() settings.
        + corrected logic of keypad() by adding internal screen state to track
          whether the terminal's keypad-mode has been set.  Use this in
          wgetch() to update the keypad-mode according to whether the
          associated window's keypad-mode has been set with keypad().  This
          corrects a related problem restoring terminal state after handling
          SIGTSTP (reported by Mike Castle).
        + regenerate configure using patch for autoconf 2.52
                autoconf-2.52-patch.gz
          at
                ftp://invisible-island.net/autoconf/
        + update config.guess, config.sub from
                http://subversions.gnu.org/cgi-bin/viewcvs/config/config/
        + minor changes to quoting in configure script to allow it to work
          with autoconf 2.52

20011208
        + modify final checks in lib_setup.c for line and col values, making
          them independent.
        + modify acs_map[] if configure --broken-linker is specified, to make
          it use a function rather than an array (prompted by an incorrect
          implementation in cygwin package).
        + correct spelling of configure option --enable-colorfgbg, which
          happened to work if --with-develop was set (noted in cygwin package
          for ncurses).
        + modify ifdef for genericerror() to compile with SUNWspro Sun WorkShop
          6 update 1 C++ 5.2 (patch by Sullivan N Beck <sbeck@cise.ufl.edu>).
        + add configure checks to see if ncurses' fallback vsscanf() will
          compile either of the special cases for FILE structs, and if not,
          force it to the case which simply returns an error (report by
          Sullivan N Beck <sbeck@cise.ufl.edu> indicates that Solaris 8 with
          64-bits does not allow access to FILE's fields).
        + modify ifdef's for c++/cursesw.cc to use the fallback vsscanf() in
          the ncurses library if no better substitute for this can be found
          in the C++ runtime.
        + modify the build to name dynamic libraries according to the
          convention used on OS X and Darwin.  Rather than something like
          libncurses.dylib.5.2, Darwin would name it libncurses.  5.dylib.
          There are a few additional minor fixes, such as setting the library
          version and compatibility version numbers (patch by Jason Evans
          <jevans@apple.com>).
        + use 'sh' to run mkinstalldirs, to work around problems with buggy
          versions of 'make' on OS/2 (report by John Polterak <jp@eyup.org>).
        + correct typo in manpage description of curs_set() (Debian #121548).
        + replace the configure script existence-check for mkstemp() by one
          that checks if the function works, needed for older glibc and
          AmigaOS.

20011201
        + modify script that generates fallbacks.c to compile a temporary
          copy of the terminfo source in case the host does not contain all of
          the entries requested for fallbacks (request by Greg Roelofs).
        + modify configure script to accommodate systems such as Mac OS X whose
          <stdbool.h> header defines a 'bool' type inconsistent with ncurses,
          which normally makes 'bool' consistent with C++.  Include <stdbool.h>
          from curses.h to force consistent usage, define a new type
          NCURSES_BOOL and related that to the exported 'bool' as either a
          typedef or definition, according to whether <stdbool.h> is present
          (based on a bug report for tin 1.5.9 by Aaron Adams <adamsa@mac.com>).

20011124
        + added/updated terminfo entries for M$ telnet and KDE konsole -TD

20011117
        + updated/expanded Apple_Terminal and Darwin PowerPC terminfo entries
          (Benjamin C W Sittler).
        + add putty terminfo entry -TD
        + if configuring for wide-curses, define _XOPEN_SOURCE_EXTENDED, since
          this may not otherwise be defined to make test/view.c compile.

20011110
        + review/correct several missing/generated items in curses.wide, sorted
          the lists to make subsequent diff's easier to track.

20011103
        + add manual pages for add_wch(), echo_wchar(), getcchar(),
          mvadd_wch(), mvwadd_wch(), setcchar(), wadd_wch() and wecho_wchar().
        + implement wecho_wchar()
        + modify _tracedump() to handle wide-characters by mapping them to '?'
          and control-characters to '.', to make the trace file readable.  Also
          dynamically allocate the buffer used by _tracedump() for formatting
          the results.
        + modify T_CALLED/T_RETURN macros to ease balancing call/return lines
          in a trace by using curly braces.
        + implement _nc_viscbuf(), for tracing cchar_t arrays.
        + correct trace-calls in setcchar() and getcchar() functions, which
          traced the return values but not the entry to each function.
        + correct usage message in test/view.c, which still mentioned -u flag.

20011027
        + modify configure script to allow building with termcap only, or with
          fallbacks only.  In this case, we do not build tic and toe.
        + add configure --with-termpath option, to override default TERMPATH
          value of /etc/termcap:/usr/share/misc/termcap.
        + cosmetic change to tack: make menu descriptions agree with menu
          titles.

20011020
        + rewrote limit-checks in wscrl() and associated _nc_scroll_window(),
          to ensure that if the parameter of wscrl() is larger than the size of
          the scrolling region, then the scrolling region will be cleared
          (report by Ben Kohlen <bckohlen@yahoo.com>).
        + add trace/varargs.c, using this to trace parameters in lib_printw.c
        + implement _tracecchar_t2() and _tracecchar_t().
        + split-out trace/visbuf.c
        + correct typo in lib_printw.c changes from 20010922 (report by Mike
          Castle).

20011013
        + modify run_tic.sh to check if the build is a cross-compile.  In that
          case, do not use the build's tic to install the terminfo database
          (report by Rafael Rodriguez Velilla <rrv@tid.es>).
        + modify mouse click resolution so that mouseinterval(-1) will disable
          it, e.g., to handle touchscreens via a slow connection (request by
          Byron Stanoszek <gandalf@winds.org>).
        + correct mouseinterval() default value shown in curs_mouse.3x
        + remove conflicting definition of mouse_trafo() (reported by Lars
          Hecking, using gcc 2.95.3).

20011001
        + simpler fix for signal_name(), to replace the one overlooked in
          20010929 (reported by Larry Virden).

20010929
        + add -i option to view.c, to test ncurses' check for non-default
          signal handler for SIGINT, etc.
        + add cases for shared-libraries on Darwin/OS X (patch by Rob Braun
          <bbraun@synack.net>).
        + modify tset to restore original I/O modes if an error is encountered.
          Also modify to use buffered stderr consistently rather than mixing
          with write().
        + change signal_name() function to use if-then-else rather than case
          statement, since signal-values aren't really integers (reported by
          Larry Virden).
        + add limit checks in wredrawln(), fixing a problem where lynx was
          repainting a pad which was much larger than the screen.

20010922
        + fix:  PutRange() was counting the second part of a wide character as
          part of a run, resulting in a cursor position that was one too far
          (patch by Sven Verdoolaege).
        + modify resizeterm() to not queue a KEY_RESIZE if there was no
          SIGWINCH, thereby separating the two styles of SIGWINCH handling
          in test/view.c
        + simplified lib_tstp.c, modify it to use SA_RESTART flag for SIGWINCH.
        + eliminate several static buffers in the terminfo compiler, using
          allocated buffers.
        + modify MKkeyname.awk so that keyname() does not store its result into
          a static buffer that is overwritten by the next call.
        + reorganize the output of infocmp -E and -e options to compile cleanly
          with gcc -Wwrite-strings warnings.
        + remove redefinition of chgat/wchgat/mvwchgat from curses.wide

20010915
        + add label to test/view.c, showing the name of the last key or signal
          that made the screen repaint, to make it clearer when a sigwinch
          does this.
        + use ExitProgram() consistently in the test-programs to make it
          simpler to test leaks with dmalloc, etc.
        + move hashtab static data out of hashmap.c into SCREEN struct.
        + make NO_LEAK code compile with revised WINDOWLIST structs.

20010908
        + modify tgetent() to check if exit_attribute_mode resets the alternate
          character set, and if so, attempt to adjust the copy of the termcap
          "me" string which it will return to eliminate that part.  In
          particular, 'screen' would lose track of line-drawing characters
          (report by Frederic L W Meunier <0@pervalidus.net>, analysis by
          Michael Schroeder).

20010901
        + specify DOCTYPE in html manpages.
        + add missing macros for several "generated" functions:  attr_get(),
          attr_off(), attr_on(), attr_set(), chgat(), mvchgat(), mvwchgat() and
          mouse_trafo().
        + modify view.c to agree with non-experimental status of ncurses'
          sigwinch handler:
          + change the sense of the -r option, making it default to ncurses'
            sigwinch handler.
          + add a note explaining what functions are unsafe in a signal
            handler.
          + add a -c option, to set color display, for testing.
        + unset $data variable in MKterminfo.sh script, to address potential
          infinite loop if shell malfunction (report by Samuel Mikes
          <smikes@cubane.com>, for bash 2.05.0 on a Linux 2.0.36 system).
        + change kbs in mach terminfo entries to ^?  (Marcus Brinkmann
          <Marcus.Brinkmann@ruhr-uni-bochum.de>).
        + correct logic for COLORFGBG environment variable: if rxvt is compiled
          with xpm support, the variable has three fields, making it slightly
          incompatible with itself.  In either case, the background color is
          the last field.

20010825
        + move calls to def_shell_mode() and def_prog_mode() before loop with
          callbacks in lib_set_term.c, since the c++ demo otherwise initialized
          the tty modes before saving them (patch by John David Anglin
          <dave@hiauly1.hia.nrc.ca>).
        + duplicate logic used to initialize trace in newterm(), in initscr()
          to avoid confusing trace of initscr().
        + simplify allocation of WINDOW and WINDOWLIST structs by making the
          first a part of the second rather than storing a pointer.  This saves
          a call to malloc for each window (discussion with Philippe Blain).
        + remove unused variable 'used_ncv' from lib_vidattr.c (Philippe
          Blain).
        + modify c++/Makefile.in to accommodate archive programs that are
          different for C++ than for C, and add cases for vendor's C++
          compilers on Solaris and IRIX (report by Albert Chin-A-Young).
        + correct manpage description of criteria for deciding if the terminal
          supports xterm mouse controls.
        + add several configure script options to aid with cross-compiling:
          --with-build-cc, --with-build-cflags, --with-build-ldflags, and
          --with-build-libs (request by Greg Roelofs).
        + change criteria for deciding if configure is cross-compiling from
          host/build mismatch to host/target mismatch (request by Greg Roelofs
          <greg.roelofs@philips.com>).
        + correct logic for infocmp -e and -E options which writes the data for
          the ext_Names[] array.  This is needed if one constructs a fallback
          table for a terminfo entry which uses extended termcap names, e.g.,
          AX in a color xterm.
        + fix undefined NCURSES_PATHSEP when configure --disable-database
          option is given.

20010811
        + fix for VALID_BOOLEAN() macro when char is not signed.
        + modify 'clean' rule for C++ binding to work with Sun compiler, which
          caches additional information in a subdirectory of the objects.
        + added llib-ncursesw.

20010804
        + add Caps.keys example for experimental extended function keys
          (adapted from a patch by Ilya Zakharevich).
        + correct parameter types of vidputs() and vidattr() to agree with
          header files (report by William P Setzer).
        + fix typos in several man-pages (patch by William P Setzer).
        + remove unneeded ifdef for __GNUG__ in CF_CPP_VSCAN_FUNC configure
          macro, which made ncurses C++ binding fail to build with other
          C++ compilers such as HPUX 11.x (report by Albert Chin-A-Young).
        + workaround for bug in HPUX 11.x C compiler: add a blank after
          NCURSES_EXPORT macro in form.h (report by Albert Chin-A-Young)
        + ignore blank lines in Caps* files in MKkey_defs.sh script (report by
          Albert Chin-A-Young).
        + correct definition of key_end in Caps.aix4, which left KEY_END
          undefined (report by Albert Chin-A-Young).
        + remove a QNX-specific fallback prototype for vsscanf(), which is
          obsolete with QNX RTP.
        + review/fix some of the T() and TR() macro calls, having noticed that
          there was no data for delwin() in a trace of dialog because there was
          no returnVoid call for wtimeout().  Also, traces in lib_twait.c are
          now selected under TRACE_IEVENT rather than TRACE_CALLS.

20010728
        + add a _nc_access() check before opening files listed via $TERMPATH.
        + using modified man2html, regenerate some of the html manpages to fix
          broken HREF's where the link was hyphenated.

20010721
        + add some limit/pointer checks to -S option of tputs.
        + updated/expanded Apple_Terminal and Darwin PowerPC terminfo entries
          (Benjamin C W Sittler).
        + add a note in curs_termcap.3x regarding a defect in the XSI
          description of tgetent (based on a discussion with Urs Jansen
          regarding the HPUX 11.x implementation, whose termcap interface is
          not compatible with existing termcap programs).
        + modify manhtml rule in dist.mk to preserve copyright notice on the
          generated files, as well as to address HTML style issues reported by
          tidy and weblint.  Regenerated/updated corresponding html files.
        + comment out use of Protected_Character and related rarely used
          attributes in ncurses Ada95 test/demo to compile with wide-character
          configuration.

20010714
        + implement a simple example in C++ demo to test scanw().
        + corrected stdio function used to implement scanw() in cursesw.cc
        + correct definition of RemAttr() macro from 20010602 changes, which
          caused C++ SillyDemo to not show line-drawing characters.
        + modify C++ binding, adding getKey() which can be overridden by user
          to substitute functions other than getch() for keyboard processing
          of forms and menus (patch by Juergen Pfeifer).

20010707
        + fix some of the trace calls which needed modification to work with
          new wide-character structures.
        + modify magic-cookie code in tty_update.c to compile with new
          wide-character structures (report by <George.R.Goffe@seagate.com>).
        + ensure that _XOPEN_SOURCE_EXTENDED is defined in curses.priv.h if
          compiling for wide-character configuration.
        + make addwnstr() handle non-spacing characters (patch by Sven
          Verdoolaege).

20010630
        + add configure check to define _GNU_SOURCE, needed to prop up glibc
          header files.
        + split-out include/curses.wide to solve spurious redefinitions caused
          by defining _GNU_SOURCE, and move includes for <signal.h> before
          <curses.h> to work around misdefinition of ERR in glibc 2.1.3 header
          file.
        + extended ospeed change to NetBSD and OpenBSD -TD
        + modify logic in lib_baudrate.c for ospeed, for FreeBSD to make it
          work properly for termcap applications (patch by Andrey A Chernov).

20010623
        + correct an overlooked CharOf/UChar instance (reports by Eugene Lee
          <eugene@anime.net>, Sven Verdoolaege).
        + correct unneeded ifdef for wunctrl() (reported by Sven Verdoolaege)

20010618
        + change overlooked several CharOf/UChar instances.
        > several patches from Sven Verdoolaege:
        + correct a typo in wunctrl(), which made it appear that botwc() was
          needed (no such function: use btowc()).
        + reimplement wide-character demo in test/view.c, using new functions.
        + implement getcchar(), setcchar(), wadd_wchnstr() and related macros.
        + fix a syntax problem with do/if/while in PUTC macro (curses.priv.h).

20010616
        + add parentheses in macros for malloc in test.priv.h, fixes an
          expression in view.c (report by Wolfgang Gutjahr <gutw@knapp.co.at>).
        + add Caps.uwin, as an example.
        + change the way curses.h is generated, making the list of function
          key definitions extracted from the Caps file.
        + add #undef's before possible redefinition of ERR and OK in curses.h
        + modify logic in tic, toe, tput and tset which checks for basename of
          argv[0] to work properly on systems such as OS/2 which have
          case-independent filenames and/or program suffixes, e.g., ".ext".

20010609
        + add a configure check, if --enable-widec is specified, for putwc(),
          which may be in libutf8.
        + remove some unnecessary text from curs_extend.3x and
          default_colors.3x which caused man-db to make incorrect symbolic
          links (Debian #99550).
        + add configure check if cast for _IO_va_list is needed to compile
          C++ vscan code (Debian #97945).
        > several patches from Sven Verdoolaege:
        + correct code that used non-standard auto-initialization of a struct,
          which gcc allows (report by Larry Virden).
        + use putwc() in PUTC() macro.
        + make addstr() work for the special case where the codeset is
          non-stateful (eg. UTF-8), as well as stateful codesets.

20010603
        + correct loop expression in NEXT_CHAR macro for lib_addstr.c changes
          from 20010602 (report by Mike Castle).

20010602
        + modify mvcur() to avoid emitting newline characters when nonl() mode
          is set.  Normally this is not a problem since the actual terminal
          mode is set to suppress nl/crlf translations, however it is useful to
          allow the caller to manipulate the terminal mode to avoid staircasing
          effects after spawning a process which writes messages (for lynx
          2.8.4) -TD
        > several patches from Sven Verdoolaege <skimo@kotnet.org>:
        + remove redundant type-conversion in fifo_push()
        + correct definition of addwstr() macro in curses.h.in
        + remove _nc_utf8_outch()
        + rename most existing uses of CharOf() to UChar(), e.g., where it is
          used to prevent sign-extension in ctype macros.
        + change some chtype's to attr_t's where the corresponding variables
          are used to manipulate attributes.
        + UpdateAttr() was applied to both attributes (attr_t) and characters
          (chtype).  Modify macro and calls to it to make these distinct.
        + add CharEq() macro, use in places where wide-character configuration
          implementation uses a struct for cchar_t.
        + moved struct ldat into curses.priv.h, to hide implementation details.
        + change CharOf() macro to use it for masking A_CHARTEXT data from
          chtype's.
        + add L() macro to curses.priv.h, for long-character literals.
        + replace several assignments from struct ldat entries to chtype or
          char values with combinations of CharOf() and AttrOf() macros.
        + add/use intermediate ChAttrOf() and ChCharOf() macros where we know
          we are using chtype data.
        + add/use lowlevel attribute manipulation macros AddAttr(), RemAttr()
          and SetAttr().
        + add/use SetChar() macro, to change a cchar_t based on a character and
          attributes.
        + convert most internal use of chtype to NCURSES_CH_T, to simplify use
          of cchar_t for wide-character configuration.  Similarly, use ARG_CH_T
          where a pointer would be more useful.
        + add stubs for tracing cchar_t values.
        + add/use macro ISBLANK()
        + add/use constructors for cchar_t's: NewChar(), NewChar2().
        + add/use macros CHREF(), CHDEREF(), AttrOfD(), CharOfD() to facilitate
          passing cchar_t's by address.
        + add/use PUTC_DATA, PUTC() macros.
        + for wide-character configuration, move the window background data to
          the end of the WINDOW struct so that whether _XOPEN_SOURCE_EXTENDED
          is defined or not, the offsets in the struct will not change.
        + modify addch() to work with wide-characters.
        + mark several wide-character functions as generated in curses.h.in
        + implement wunctrl(), wadd_wch(), wbkgrndset(), wbkgrnd(),
          wborder_set() and waddnwstr().

20010526
        + add experimental --with-caps=XXX option to customize to similar
          terminfo database formats such as AIX 4.x
        + add Caps.aix4 as an example.
        + modify Caps to add columns for the the KEY_xxx symbols.
        + modify configure --with-widec to suppress overwrite of libcurses.so
          and curses.h
        + add checks to toe.c to avoid being confused by files and directories
          where we would expect the reverse, e.g., source-files in the
          top-level terminfo levels as is the case for AIX.

20010519
        + add top-level 'depend' rule for the C sources, assuming that the
          makedepend program is available.  As a side-effect, this makes
          the generated sources, as in "make sources" (prompted by a report
          by Mike Castle that "make -j" fails because the resulting parallel
          processes race to generate ncurses/names.c).
        + modify configure script so that --disable-overwrite option's action
          to add a symbolic link for libcurses applies to the static library as
          well as the shared library when both are configured (report by Felix
          Natter <f.natter@ndh.net>).
        + add ELKS terminfo entries (Federico Bianchi
          <bianchi@www.arte.unipi.it>)
        + add u6 (CSR) to Eterm (Michael Jennings).

20010512
        + modify test/ncurses.c to work with xterm-256color, which has fewer
          color pairs than colors*colors (report by David Ellement
          <ellement@sdd.hp.com>).

20010505
        + corrected screen.xterm-xfree86 entry.
        + update comment in Caps regarding IBM (AIX) function-key definitions.

20010421
        + modify c++/Makefile.in to link with libncurses++w.a when configured
          for wide-characters (patch by Sven Verdoolaege).
        + add check in _nc_trace_buf() to refrain from freeing a null pointer.
        + improve CF_PROG_INSTALL macro using CF_DIRNAME.
        + update config.guess, config.sub from autoconf 2.49e (alpha).

20010414
        + add secondary check in tic.c, similar_sgr() to see if the reason
          for mismatch was that the individual capabilities used a time-delay
          while sgr did not.  Used this to cleanup mismatches, e.g., in vt100,
          and remove time-delay from Apple_Terminal entries.
        + add Apple_Terminal terminfo entries (Benjamin C W Sittler
          <bsittler@iname.com>).
        + correct definitions of shifted editing keys for xterm-xfree86 -TD
        + fix a bug in test/bs.c from 20010407 (patch by Erik Sigra).
        + prevent relative_move() from doing an overwrite if it detects 8-bit
          characters when configured for UTF-8 (reported by Sven Verdoolaege
          <skimo@kotnet.org>).

20010407
        + add configure checks for strstream.h vscan function, and similar
          stdio-based function which may be used in C++ binding for gcc 3.0
          (reports by George Goffe, Lars Hecking, Mike Castle).
        + rewrite parts of configure.in which used changequote().  That feature
          is broken in the latest autoconf alphas (e.g., 2.49d).
        + add a missing pathname for ncurses_dll.h, needed when building in
          a directory outside the source tree (patch by Sven Verdoolaege
          <skimo@kotnet.org>).
        > fix 2 bugs in test/bs.c Erik Sigra <sigra@home.se>:
        + no ships were ever placed in the last row or in the last column.
          This made the game very easy to win, because you never had to waste
          any shots there, but the computer did.
        + the squares around a sunken ship that belonged to the player were not
          displayed as already hit by the computer, like it does for the
          player.

20010331
        + add some examples of customizing screen's terminfo:
          screen.xterm-xfree86, screen.xterm-r6, screen.teraterm -TD
        + modify screen's terminfo entry to match the khome/kend in screen
          3.09.08 (Debian #92215).
        + correct a memory leak in forms library (report by Stefan Vogtner
          <stefan@vogtner.de>) (patch by Juergen Pfeifer).

20010324
        + change symbols used to guard against repeated includes to begin
          consistently with "NCURSES_" rather than a leading underscore.  There
          are other symbols defined in the header files which begin with a
          leading underscore, but they are part of the legacy interface.
        + reorder includes in c++ binding so that rcs identifiers can be
          compiled-in.
        + add .cc.ii rule to c++ makefile, to get preprocessor output for
          debugging.
        + correct configure script handling of @keyword@ substitutions when the
          --with-manpage-renames option is given (cf: 20000715, fixes Debian
          #89939).
        + report stack underflow/overflow in tparm() when tic -cv option is
          given.
        + remove spurious "%|" operator from xterm-xfree86 terminfo entry,
          (reported by Adam Costello <amc@cs.berkeley.edu>, Debian #89222).

20010310
        + cleanup of newdemo.c, fixing some ambiguous expressions noted by gcc
          2.95.2, and correcting some conflicting color pair initializations.
        + add missing copyright notice for cursesw.h
        + review, make minor fixes for use of '::' for referring to C-language
          interface from C++ binding.
        + modify configure check for g++ library slightly to accommodate
          nonstandard version number, e.g., <vendor>-2.7 (report by Ronald Ho
          <rho@mipos2.intel.com>).
        + add configure check for c++ <sstream> header, replace hardcoded
          ifdef.
        + workaround for pre-release of gcc 3.0 libstdc++, which has dropped
          vscan from strstreambuf to follow standard, use wrapper for C vscanf
          instead (report by George Goffe <grgoffe@excite.com> and Matt Taggart
          <taggart@carmen.fc.hp.com>, fixes Debian .

20010303
        + modify interface of _nc_get_token() to pass 'silent' parameter to it,
          to make quieter loading of /etc/termcap (patch by Todd C Miller).
        + correct a few typos in curs_slk.3x and curs_outopts.3x manpages
          (patch by Todd C Miller).

20010224
        + compiler-warning fixes (reported by Nelson Beebe).

20010210
        + modify screen terminfo entry to use new 3.9.8 feature allowing xterm
          mouse controls -TD

20010203
        + broaden patterns used to match OS/2 EMX in configure script to cover
          variant used in newer config.guess/config.sub
        + remove changequote() calls from configure script, since this feature
          is broken in the autoconf 2.49c alpha, maintainers decline to fix.
        + remove macro callPutChar() from tty_update.c, since this is no longer
          needed (reported by Philippe Blain).
        + add a null-pointer check in tic.c to handle the case when the input
          file is really empty.  Modify the next_char() function in comp_scan.c
          to allow arbitrarily long lines, and incidentally supply a newline to
          files that do not end in a newline.  These changes improve tic's
          recovery from attempts to read binary files, e.g., its output from
          the terminfo database (reported by Bernhard Rosenkraenzer).

20010127
        + revert change to c++/demo.cc from 20001209, which changed definition
          of main() apparently to accommodate cygwin linker, but broke the demo
          program.
        + workaround for broken egcs 2.91.66 which calls member functions
          (i.e., lines() and colors() of NCursesWindow before calling its
          constructor.  Add calls to initialize() in a few constructors which
          did not do this already.
        + use the GNAT preprocessor to make the necessary switch between TRACE
          and NO_TRACE configurations (patch by Juergen Pfeifer).
        > patches by Bernhard Rosenkraenzer:
        + modify kterm terminfo entry to use SCS sequence to support alternate
          character set (it does not work with SI/SO).
        + --with-ospeed=something didn't work.  configure.in checked for a
          $enableval where it should check for $withval.  Also,
          ncurses/llib-lncurses still had a hardcoded short.

20010114
        + correction to my merge of Tom Riddle's patch that broke tic in some
          conditions (reported by Enoch Wexler <enoch@wexler.co.il>) -TD

20010113
        + modify view.c to test halfdelay().  Like other tests, this recognizes
          the 's' and space commands for stopping/starting polled input, shows
          a freerunning clock in the header.  If given a parameter to 's', that
          makes view.c use halfdelay() with that parameter rather than
          nodelay().
        + fix to allow compile with the experimental configure option
          --disable-hashmap.
        + modify postprocess_termcap() to avoid overwriting key_backspace,
          key_left, key_down when processing a non-base entry (report/patch by
          Tom Riddle).
        + modify _nc_wrap_entry(), adding option to reallocate the string
          table, needed in _nc_merge_entry() when merging termcap entries.
          (adapted from report/patch by Tom Riddle <ftr@oracom.com>).
        + modify a few configure script macros to keep $CFLAGS used only for
          compiler options, preprocessor options in $CPPFLAGS.

20001230
        + correct marker positions in lrtest.c after receiving a sigwinch.
        + fix ifdef's in ncurses.c to build against pre-5.2 for testing.
        + fixes to tclock for resizing behavior, redundant computation (report
          and patch by A M Kuchling <akuchlin@mems-exchange.org>).

20001216
        + improved scoansi terminfo entry -TD
        + modify configure script and makefile in Ada95/src to compile a stub
          for the trace functions when ncurses does not provide those.

20001209
        + add ncurses_dll.h and related definitions to support generating DLL's
          with cygwin (adapted from a patch by Charles Wilson
          <cwilson@ece.gatech.edu>, changed NCURSES_EXPORT macro to make it
          work with 'indent') -TD

20001202
        + correct prototypes for some functions in curs_termcap.3x, matching
          termcap.h, which matches X/Open.
        > patch by Juergen Pfeifer:
        + a revised version of the Ada enhancements sent in by "H.
          Nanosecond", aka Eugene V Melaragno <aldomel@ix.netcom.com>.  This
          patch includes
          - small fixes to the existing ncurses binding
          - addition of some more low-level functions to the binding, including
            termcap and terminfo functions
          - An Ada implementation of the "ncurses" test application originally
            written in C.

20001125
        + modify logic in lib_setup.c to allow either lines or columns value
          from terminfo to be used if the screen size cannot be determined
          dynamically rather than requiring both (patch by Ehud Karni
          <ehud@unix.simonwiesel.co.il>).
        + add check in lib_tgoto.c's is_termcap() function to reject null or
          empty strings (reported by Valentin Nechayev <netch@netch.kiev.ua> to
          freebsd-bugs).
        + add definition from configure script that denotes the path-separator,
          which is normally a colon.  The path-separator is a semicolon on
          OS/2 EMX and similar systems which may use a colon within pathnames.
        + alter logic to set default for --disable-overwrite option to set it
          to 'yes' if the --prefix/$prefix value is not /usr/local, thereby
          accommodating the most common cause of problems: gcc's nonstandard
          search rules.  Other locations such as /usr/local/ncurses will
          default to overwriting (report by Lars Hecking <lhecking@nmrc.ie>).

20001118
        + modify default for --disable-overwrite configure option to disable
          if the --prefix or $prefix value is not /usr.
        + add cygwin to systems for which ncurses is installed by default into
          /usr rather than /usr/local.

20001111
        + minor optimization in comp_error.c and lib_termname.c, using
          strncat() to replace strncpy() (patch by Solar Designer).
        + add a use_terminfo_vars() check for $HOME/.termcap, and check for
          geteuid() to use_terminfo_vars() (patch by Solar Designer
          <solar@false.com>).
        + improved cygwin terminfo entry, based on patch by
          <ernie_boyd@yahoo.com>.
        + modify _nc_write_entry() to allow for the possibility that linking
          aliases on a filesystem that ignores case would not succeed because
          the source and destination differ only by case, e.g., NCR260VT300WPP0
          on cygwin (report by Neil Zanella).
        + fix a typo in the curs_deleteln.3x man page (patch by Bernhard
          Rosenkraenzer <bero@redhat.de>).

20001104
        + add configure option --with-ospeed to assist packagers in transition
          to 5.3 change to ospeed type.
        + add/use CharOf() macro to suppress sign-extension of char type on
          platforms where this is a problem in ctype macros, e.g., Solaris.
        + change trace output to binary format.
        + correct a missing quote adjustment in CF_PATH_SYNTAX autoconf
          macro, for OS/2 EMX configuration.
        + rearrange a few configure macros, moving preprocessor options to
          $CPPFLAGS (a now-obsolete version of autoconf did not consistently
          use $CPPFLAGS in both the compile and preprocessor checks).
        + add a check in relative_move() to guard against buffer overflow in
          the overwrite logic.

20001028
        + add message to configure script showing g++ version.
        + resync config.guess, config.sub
        + modify lib_delwin.c, making it return ERR if the window did not exist
          (suggested by Neil Zanella).
        + add cases for FreeBSD 3.1 to tdlint and makellib scripts, used this
          to test/review ncurses library.  (Would use lclint, but it doesn't
          work).
        + reorganized knight.c to avoid forward references.  Correct screen
          updates when backtracking, especially to the first cell.  Add F/B/a
          commands.

20001021 5.2 release for upload to ftp.gnu.org
        + update generated html files from manpages.
        + modify dist.mk to use edit_man.sh to substitute autoconf'd variables
          in html manpages.
        + fix an uninitialized pointer in read_termcap.c (report by Todd C
          Miller, from report/patch by Philip Guenther <guenther@gac.edu>).
        + correct help-message and array limit in knight.c (patch by Brian
          Raiter <breadbox@muppetlabs.com>).
        > patch by Juergen Pfeifer:
        + fix to avoid warning by GNAT-3.13p about use of inconsistent casing
          for some identifiers defined in the standard package.
        + cosmetic change to forms/fty_enum.c

20001014
        + correct an off-by-one position in test/railroad.c which could cause
          wrapping at the right margin.
        + test/repair some issues with libtool configuration.  Make
          --disable-echo force libtool --silent.  (Libtool does not work for
          OS/2 EMX, works partly for SCO - libtool is still very specific to
          gcc).
        + change default of --with-manpage-tbl to "no", since for most of the
          platforms which do have tbl installed, the system "man" program
          understands how to run tbl automatically.
        + minor improvement to force_bar() in comp_parse.c (Bernhard
          Rosenkraenzer <bero@redhat.de>).
        + modify lib_tparm.c to use get_space() before writing terminating
          null character, both for consistency as well as to ensure that if
          save_char() was called immediately before, that the allocated memory
          is enough (patch by Sergei Ivanov).
        + add note about termcap ML capability which is duplicated between two
          different capabilities:  smgl and smglr (reported by Sergei Ivanov
          <svivanov@pdmi.ras.ru>).
        + correct parameter counts in include/Caps for dclk as well as some
          printer-specific capabilities: csnm, defc, scs, scsd, smgtp, smglp.
        > patch by Johnny C Lam <lamj@stat.cmu.edu>:
        + add support for building with libtool (apparently version 1.3.5,
          since old versions do not handle -L../lib), using new configure
          option --with-libtool.
        + add configure option --with-manpage-tbl, which causes the manpages to
          be preprocessed by tbl(1) prior to installation,
        + add configure option --without-curses-h, which causes the
          installation process to install curses.h as ncurses.h and make
          appropriate changes to headers and manpages.

20001009
        + correct order of options/parameters in run_tic.in invocation of tic,
          which did not work with standard getopt() (reported by Ethan
          Butterfield <primus@veris.org>).
        + correct logic for 'reverse' variable in lib_vidattr.c, which was
          setting it true without checking if newmode had A_REVERSE set, e.g.,
          using $TERM=ansi on OS/2 EMX (see 20000917).
        > patch by Todd C Miller:
        + add a few missing use_terminfo_vars() and fixes up _nc_tgetent().
          Previously, _nc_cgetset() would still get called on cp so the
          simplest thing is to set cp to NULL if !use_terminfo_vars().
        + added checks for an empty $HOME environment variable.
        > patches for OS/2 EMX (Ilya Zakharevich):
        + modify convert_configure.pl to support INSTALL.  Change compiler
          options in that script to use multithreading, needed for the mouse.
        + modify OS/2 mouse support, retrying as a 2-button mouse if code fails
          to set up a 3-button mouse.
        + improve code for OS/2 mouse support, using _nc_timed_wait() to
          replace select() call.

20001007
        + change type of ospeed variable back to short to match its use in
          legacy applications (reported by Andrey A Chernov).
        + add case to configure script for --enable-rpath on IRIX (patch by
          Albert Chin-A-Young).
        + minor fix to position_check() function, to ensure it gets the whole
          cursor report before decoding.
        + add configure option --disable-assumed-color, to allow pre-5.1
          convention of default colors used for color-pair 0 to be configured
          (see assume_default_colors()).
        + rename configure option --enable-hashmap --disable-hashmap, and
          reorder the configure options, splitting the experimental and
          development
        + add configure option --disable-root-environ, which tells ncurses to
          disregard $TERMINFO and similar environment variables if the current
          user is root, or running setuid/setgid (based on discussion with
          several people).
        + modified misc/run_tic.in to use tic -o, to eliminate dependency on
          $TERMINFO variable for installs.
        + add table entry for plab_norm to tput, so it passes in strings
          for that capability.
        + modify parse_format() in lib_tparm.c to ignore precision if it is
          longer than 10000 (report by Jouko Pynnonen).
        + rewrote limit checks in lib_mvcur.c using new functions
          _nc_safe_strcat(), etc.  Made other related changes to check lengths
          used for strcat/strcpy (report by Jouko Pynnonen
          <jouko@solutions.fi>).

20000930
        + modify several descriptions, including those for setaf, setab, in
          include/Caps to indicate that the entries are parameterized.  This
          information is used to tell which strings are translated when
          converting to termcap.  Fixes a problem where the generated termcap
          would contain a spurious "%p1" for the terminfo "%p1%d".
        + modify ld -rpath options (e.g., Linux, and Solaris) to use an
          absolute pathname for the build tree's lib directory (prompted by
          discussion with Albert Chin-A-Young).
        + modify "make install.man" and "make uninstall.man" to include tack's
          man-page.
        + various fixes for install scripts used to support configure --srcdir
          and --with-install-prefix (reported by Matthew Clarke
          <Matthew_Clarke@mindlink.bc.ca>).
        + make configure script checks on variables $GCC and $GXX consistently
          compare against 'yes' rather than test if they are nonnull, since
          either may be set to the corresponding name of the C or C++ compiler
          (report/patch by Albert Chin-A-Young).

20000923
        + modify rs2 capability in xterm-r6 and similar where cursor
          save/restore bracketed the sequence for resetting video attributes.
          The cursor restore would undo that (report by John Hawkinson
          <jhawk@MIT.EDU> (see NetBSD misc/11052)).
        + using parameter check added to tic, corrected 27 typos in
          terminfo.src -TD
        + modify tic to verify that its inputs are really files, in case
          someone tries to read a directory (or /dev/zero).
        + add a check for empty buffers returned by fgets() in comp_scan.c
          next_char() function, in case tic is run on a non-text file (fixes
          a core dump reported by Aaron Campbell <aaron@cs.dal.ca>).
        + add to railroad.c some code exercising tgoto(), providing an
          alternate form of display if the terminal supports cursor addressing.
        + split-out tgoto() again, this time into new file lib_tgoto.c, and
          implement a conventional BSD-style tgoto() which is used if the
          capability string does not contain terminfo-style padding or
          parameters (requested by Andrey A Chernov).
        + add check to tic which reports capabilities that do not reference
          the expected number of parameters.
        + add error checking to infocmp's -v and -m options to ensure that
          the option value is indeed a number.
        + some cleanup of logic in _nc_signal_handler() to verify if SIGWINCH
          handler is setup.  Separated the old/new sigaction data for SIGTSTP
          from the other signals.

20000917
        + add S0, E0 extensions to screen's terminfo entry, which is another
          way to solve the misconfiguration issue -TD
        + completed special case for tgoto from 20000916

20000916
        + update xterm terminfo entries to match XFree86 xterm patch #146 -TD
        + add Matrix Orbital terminfo entries (from Eric Z Ayers
          <eric@ale.org>).
        + add special case to lib_tparm.c to allow 'screen' program to use a
          termcap-style parameter "%." to tgoto() for switching character sets.
        + use LN_S substitution in run_tic.in, to work on OS/2 EMX which has
          no symbolic links.
        + updated notes in README.emx regarding autoconf patches.
        + replace a lookup table in lib_vidattr.c used to decode no_color_video
          with a logic expression (suggested by Philippe Blain).
        + add a/A toggle to ncurses.c 'b' test, which clears/sets alternate
          character set attribute from the displayed text.
        + correct inequality in parameter analysis of rewritten lib_tparm.c
          which had the effect of ignoring p9 in set_attributes (sgr), breaking
          alternate character set (reported by Piotr Majka <charvel@link.pl>).
        + correct ifdef'ing for GCC_PRINTF, GCC_SCANF which would not compile
          with Sun WorkShop compilers since these tokens were empty (cf:
          20000902, reported by Albert Chin-A-Young).

20000909
        + correct an uninitialized parameter to open_tempfile() in tic.c which
          made "tic -I" give an ambiguous error message about tmpnam.
        + add special case in lib_vidattr.c to reset underline and standout for
          devices that have no sgr0 defined (patch by Don Lewis
          <Don.Lewis@tsc.tdk.com>).  Note that this will not work for bold
          mode, since there is no exit-bold-mode capability.
        + improved patch for Make_Enum_Type (patch by Juergen Pfeifer).
        + modify tparm to disallow arithmetic on strings, analyze the varargs
          list to read strings as strings and numbers as numbers.
        + modify tparm's internal function spop() to treat a null pointer as
          an empty string.
        + modify tput program so it can be renamed or invoked via a link as
          'reset' or 'init', producing the same effect as 'tput reset' or 'tput
          init'.
        + add private entrypoint _nc_basename(), use to consolidate related
          code in progs, as well as accommodating OS/2 EMX pathnames.
        + remove NCURSES_CONST line from edit_cfg.sh to compensate for its
          removal (except via AC_SUBST) from configure.in, making
          --enable-const work again (reported by Juergen Pfeifer).
        + regen'd configure to pick up "hpux*" change from 20000902.

20000902
        + modify tset.c to check for transformed "reset" program name, if any.
        + add a check for null pointer in Make_Enum_Type() (reported by Steven
          W Orr <steveo@world.std.com>).
        + change functions _nc_parse_entry() and postprocess_termcap() to avoid
          using strtok(), because it is non-reentrant (reported by Andrey A
          Chernov <ache@nagual.pp.ru>).
        + remove "hpux10.*" case from CF_SHARED_OPTS configure script macro.
          This differed from the "hpux*" case by using reversed symbolic
          links, which made the 5.1 version not match the configuration of
          5.0 shared libraries (reported by Albert Chin-A-Young).
        + correct a dependency in Ada95/src/Makefile.in which prevented
          building with configure --srcdir (patch by H Nanosecond
          <aldomel@ix.netcom.com>).
        + modify ifdef's in curses.h.in to avoid warning if GCC_PRINTF or
          GCC_SCANF was not previously defined (reported by Pavel Roskin
          <proski@gnu.org>).
        + add MKncurses_def.sh to generate fallback definitions for
          ncurses_cfg.h, to quiet gcc -Wundef warnings, modified ifdef's in
          code to consistently use "#if" rather than "#ifdef".

20000826
        + add QNX qansi entries to terminfo -TD
        + add os2 entry to misc/emx.src (<jmcoopr@webmail.bmi.net>).
        + add configure option --with-database to allow specifying a different
          terminfo source-file to install.  On OS/2 EMX, this defaults to
          misc/emx.src
        + change misc/run_tic.sh to derive it from misc/run_tic.in, to simplify
          setting .exe extension on OS/2 EMX.
        + add .exe extension in Ada95/gen/Makefile.in,
          Ada95/samples/Makefile.in, for OS/2 EMX (reported by
          <jmcoopr@webmail.bmi.net>).
        + add configure check for filesystems (such as OS/2 EMX) which do not
          distinguish between upper/lowercase filenames, use this to fix tags
          rules in makefiles.
        + initialize fds[] array to 0's in _nc_timed_wait(); apparently poll()
          only sets the revents members of that array when there is activity
          corresponding to the related file (report by Glenn Cooper
          <gcooper@qantas.com.au>, using Purify on Solaris 5.6).
        + change configure script to use AC_CANONICAL_SYSTEM rather than
          AC_CANONICAL_HOST, which means that configure --target will set
          a default program-prefix.
        + add note on cross-compiling to INSTALL (which does not rely on the
          AC_CANONICAL_* macros).

20000819
        + add cases for EMX OS/2 to config.guess, config.sub
        + new version of config.guess, config.sub from lynx 2.8.4dev.7
        + add definitions via transform.h to allow tic and tput to check for
          the transformed aliases rather than the original infotocap, etc.
        + simplify transform-expressions in progs/Makefile.in, make the
          uninstall rule work for transformed program names.
        + change symbol used by --install-prefix configure option from
          INSTALL_PREFIX to DESTDIR (the latter has become common usage
          although the name is misleading).
        + modify programs to use curses_version() string to report the version
          of ncurses with which they are compiled rather than the
          NCURSES_VERSION string.  The function returns the patch level in
          addition to the major and minor version numbers.

20000812
        + modify CF_MAN_PAGES configure macro to make transformed program names
          a parameter to that macro rather than embedding them in the macro.
        + newer config.guess, config.sub (reference version used in lynx
          2.8.4dev.7).
        + add configure option --with-default-terminfo-dir=DIR to allow
          specifying the default terminfo database directory (request by Albert
          Chin-A-Young).
        + minor updates for terminfo.src from FreeBSD termcap change-history.
        + correct notes in README and INSTALL regarding documentation files
          that were moved from misc directory to doc (report by Rich Kulawiec
          <rsk@gsp.org>).
        + change most remaining unquoted parameters of 'test' in configure
          script to use quotes, for instance fixing a problem in the
          --disable-database option (reported by Christian Mondrup
          <scancm@biobase.dk>).
        + minor adjustments to work around some of the incompatibilities/bugs
          in autoconf 2.29a alpha.
        + add -I/usr/local/include when --with-ncurses option is used in
          test/configure script.
        + correct logic in adjust_cancels(), which did not check both
          alternatives when reclassifying an extended name between boolean,
          number and string, causing an infinite loop in tic.

20000730
        + correct a missing backslash in curses.priv.h

20000729
        + change handling of non_dest_scroll_region in tty_update.c to clear
          text after it is shifted in rather than before shifting out.  Also
          correct row computation (reported by Ruediger Kuhlmann
          <uck4@rz.uni-karlsruhe.de>).
        + add/use new trace function to display chtype values from winch() and
          getbkgd().
        + add trace mask TRACE_ATTRS, alter several existing _tracef calls that
          trace attribute changes under TRACE_CALLS to use this.
        + modify MKlib_gen.sh so that functions returning chtype will call
          returnChar().
        + add returnChar() trace, for functions returning chtype.
        + change indent.pro to line up parenthesis.

20000722
        + fix a heap problem with the c++ binding (report by
          <alexander_liberson@ninewest.com>, patch by Juergen Pfeifer).
        + minor adjustment to ClrToEOL() to handle an out-of-bounds parameter.
        + modify the check for big-core to force a couple of memory accesses,
          which may work as needed for older/less-capable machines (if not,
          there's still the explicit configure option).
        > fixes based on diff's for Amiga and BeOS found at
          http://www.mathematik.uni-karlsruhe.de/~kuhlmann/cross/ncurses/
        + alter definition of NCURSES_CONST to make it non-empty.
        + add amiga-vnc terminfo entry.
        + redefine 'TEXT' in menu.h for AMIGA, since it is reported to have
          an (unspecified) symbol conflict.
        + replaced case-statement in _nc_tracebits() for CSIZE with a table to
          simplify working around implementations that define random
          combinations of the related macros to zero.
        + modify configure test for tcgetattr() to allow for old
          implementations, e.g., on BeOS, which only defined it as a macro.

        + when checking LC_ALL/LC_CTYPE/LANG environment variables for UTF-8
          locale, ignore those which are set to an empty value, as per SUSV2.
        + encode 0xFFFD in UTF-8 with 3 bytes, not 2.
        + modify _nc_utf8_outch() to avoid sign-extension when checking for
          out-of-range value.

20000715
        + correct manlinks.sed script to avoid using ERE "\+", which is not
          understood by older versions of sed (patch by Albert Chin-A-Young).
        + implement configure script options that transform installed program
          names, e.g., --program-prefix, including the manpage names and cross
          references (patch by Albert Chin-A-Young <china@thewrittenword.com>).
        + correct several mismatches between manpage filename and ".TH"
          directives, renaming dft_fgbg.3x to default_colors.3x and
          menu_attribs.3x to menu_attributes.3x (report by Todd C Miller).
        + correct missing includes for <string.h> in several places, including
          the C++ binding.  This is not noted by gcc unless we use the
          -fno-builtin option (reported by Igor Schein <igor@txc.com>).
        + modified progs/tset.c and tack/sysdep.c to build with sgttyb
          interface if neither termio or termios is available.  Tested this
          with FreeBSD 2.1.5 (which does have termios - but the sgttyb does
          work).

20000708 5.1 release for upload to ftp.gnu.org
        + document configure options in INSTALL.
        + add man-page for ncurses trace functions.
        + correct return value shown in curs_touch.3x for is_linetouched() and
          is_wintouched(), in curs_initscr.3x for isendwin(), and in
          curs_termattr.3x for has_ic() and has_il().
        + add prototypes for touchline() and touchwin(), adding them to the
          list of generated functions.
        + modify fifo_push() to put ERR into the fifo just like other values to
          return from wgetch().  It was returning without doing that, making
          end-of-file condition incorrectly return a 0 (reported by Todd C
          Miller).
        + uncomment CC_SHARED_OPTS for progs and tack (see 971115), since they
          are needed for SCO OpenServer.
        + move _nc_disable_period from free_ttype.c to comp_scan.c to appease
          dynamic loaders on SCO and IRIX64.
        + add "-a" option to test/ncurses.c to invoke assume_default_colors()
          for testing.
        + correct assignment in assume_default_colors() which tells ncurses
          whether to use default colors, or the assumed ones (reported by Gary
          Funck <gary@Intrepid.Com>).
        + review/correct logic in mk-1st.awk for making symbolic links for
          shared libraries, in particular for FreeBSD, etc.
        + regenerate misc/*.def files for OS/2 EMX dll's.
        + correct quoting of values for CC_SHARED_OPTS in aclocal.m4 for
          cases openbsd2*, openbsd*, freebsd* and netbsd* (patch by Peter
          Wemm) (err in 20000610).
        + minor updates to release notes, as well as adding/updating URLs for
          examples cited in announce.html
        > several fixes from Philippe Blain <philippe.blain2@freesbee.fr>:
        + correct placement of ifdef for NCURSES_XNAMES in function
          _nc_free_termtype(), fixes a memory leak.
        + add a call to _nc_synchook() to the end of function whline() like
          that in wvline() (difference was in 1.9.4).
        + make ClearScreen() a little faster by moving two instances of
          UpdateAttr() out of for-loops.
        + simplify ClrBottom() by eliminating the tstLine data, using for-loops
          (cf: 960428).

20000701 pre-release
        + change minor version to 1, i.e., ncurses 5.1
        + add experimental configure option --enable-colorfgbg to check for
          $COLORFGBG variable as set by rxvt/aterm/Eterm.
        + add Eterm terminfo entry (Michael Jennings <mej@valinux.com>).
        + modify manlinks.sed to pick aliases from the SYNOPSIS section, and
          several manpages so manlinks.sed can find aliases for creating
          symbolic links.
        + add explanation to run_tic.sh regarding extended terminal
          capabilities.
        + change message format for edit_cfg.sh, since some people interpret
          it as a warning.
        + correct unescaped '$' in sysv5uw7*|unix_sv* rule for CF_SHARED_OPTS
          configure macro (report by Thanh Ma <Thanh.Ma@casi-rusco.com>).
        + correct logic in lib_twait.c as used by lib_mouse.c for GPM mouse
          support when poll() is used rather than select() (prompted by
          discussion with David Allen <DAllen24@aol.com>).

20000624 pre-release
        + modify TransformLine() to check for cells with different color pairs
          that happen to render the same display colors.
        + apply $NCURSES_NO_PADDING to cost-computation in mvcur().
        + improve cost computation in PutRange() by accounting for the use
          of parm_right_cursor in mvcur().
        + correct cost computation in EmitRange(), which was not using the
          normalized value for cursor_address.
        + newer config.guess, config.sub (reference version used in TIN 1.5.6).

20000617
        + update config.guess, config.sub (reference version used in PCRE 3.2).
        + resync changes to gnathtml against version 1.22, regenerated html
          files under doc/html/ada using this (1.22.1.1).
        + regenerated html files under doc/html/man after correcting top and
          bottom margin options for man2html in dist.mk
        + minor fixes to test programs ncurses 'i' and testcurs program to make
          the subwindow's background color cover the subwindow.
        + modify configure script so AC_MSG_ERROR is temporarily defined to a
          warning in AC_PROG_CXX to make it recover from a missing C++ compiler
          without requiring user to add --without-cxx option (adapted from
          comment by Akim Demaille <akim@epita.fr> to autoconf mailing list).
        + modify headers.sh to avoid creating temporary files in the build
          directory when installing headers (reported by Sergei Pokrovsky
          <pok@nbsp.nsk.su>)

20000610
        + regenerated the html files under doc/html/ada/files and
          doc/html/ada/funcs with a slightly-improved gnathtml.
        + add kmous capability to linux terminfo entry to allow it to use
          xterm-style events provided by gpm patch by Joerg Schoen.
        + make the configure macro CF_SHARED_OPTS a little smarter by testing
          if -fPIC is supported by gcc rather than -fpic.  The former option
          allows larger symbol tables.
        + update config.guess and config.sub (patches by
          Kevin Buettner <kev@primenet.com> (for elf64_ia64),
          Bernd Kuemmerlen <bkuemmer@mevis.de> (for MacOS X)).
        + add warning for 'tic -cv' about use of '^?' in terminfo source, which
          is an extension.

20000527
        + modify echo() behavior of getch() to match Solaris curses for
          carriage return and backspace (reported by Neil Zanella).
        + change _nc_flush() to a function.
        + modify delscreen() to check if the output stream has been closed, and
          if so, free the buffer allocated for setbuf (this provides an
          ncurses-specific way to avoid a memory leak when repeatedly calling
          newterm reported by Chipp C <at_1@zdnetonebox.com>).
        + correct typo in curs_getch.3x manpage regarding noecho (reported by
          David Malone <dwmalone@maths.tcd.ie>).
        + add a "make libs" rule.
        + make the Ada95 interface build with configure --enable-widec.
        + if the configure --enable-widec option is given, append 'w' to names
          of the generated libraries (e.g., libncursesw.so) to avoid conflict
          with existing ncurses libraries.

20000520
        + modify view.c to make a rudimentary viewer of UTF-8 text if ncurses
          is configured with the experimental wide-character support.
        + add a simple UTF-8 output driver to the experimental wide-character
          support.  If any of the environment variables LC_ALL, LC_CTYPE or
          LANG contain the string "UTF-8", this driver will be used to
          translate the output to UTF-8.  This works with XFree86 xterm.
        + modify configure script to allow building shared libraries on BeOS
          (from a patch by Valeriy E Ushakov).
        + modify lib_addch.c to allow repeated update to the lower-right
          corner, rather than displaying only the first character written until
          the cursor is moved.  Recent versions of SVr4 curses can update the
          lower-right corner, and behave this way (reported by Neil Zanella).
        + add a limit-check in _nc_do_color(), to avoid using invalid color
          pair value (report by Brendan O'Dea <bod@compusol.com.au>).

20000513
        + the tack program knows how to use smcup and rmcup but the "show caps
          that can be tested" feature did not reflect this knowledge.  Correct
          the display in the menu tack/test/edit/c (patch by Daniel Weaver).
        + xterm-16color does allow bold+colors, removed ncv#32 from that
          terminfo entry.

20000506
        + correct assignment to SP->_has_sgr_39_49 in lib_dft_fgbg.c, which
          broke check for screen's AX capability (reported by Valeriy E Ushakov
          <uwe@ptc.spbu.ru>).
        + change man2html rule in dist.mk to workaround bug in some
          man-programs that ignores locale when rendering hyphenation.
        + change web- and ftp-site to dickey.his.com

20000429
        + move _nc_curr_token from parse_entry.c to comp_scan.c, to work around
          problem linking tack on MacOS X DP3.
        + include <sys/time.h> in lib_napms.c to compile on MacOS X DP3
          (reported by Gerben Wierda <wierda@holmes.nl>).
        + modify lib_vidattr.c to check for ncv fixes when pair-0 is not
          default colors.
        + add -d option to ncurses.c, to turn on default-colors for testing.
        + add a check to _nc_makenew() to ensure that newwin() and newpad()
          calls do not silently fail by passing too-large limits.
        + add symbol NCURSES_SIZE_T to use rather than explicit 'short' for
          internal window and pad sizes.  Note that since this is visible in
          the WINDOW struct, it would be an ABI change to make this an 'int'
          (prompted by a question by Bastian Trompetter
          <btrompetter@firemail.de>, who attempted to create a 96000-line pad).

20000422
        + add mgterm terminfo entry from NetBSD, minor adjustments to sun-ss5,
          aixterm entries -TD
        + modify tack/ansi.c to make it more tolerant of bad ANSI replies.  An
          example of an illegal ANSI resonse can be found using Microsoft's
          Telnet client.  A correct display can be found using a VT-4xx
          terminal or XFree86 xterm with:
                XTerm*VT100*decTerminalID:  450
          (patch by Daniel Weaver).
        + modify gdc.c to recognize 'q' for quit, 's' for single-step and ' '
          for resume.  Add '-n' option to force gdc's standard input to
          /dev/null, to both illustrate the use of newterm() for specifying
          alternate inputs as well as for testing signal handling.
        + minor fix for configure option --with-manpage-symlinks, for target
          directories that contain a period ('.') (reported by Larry Virden).

20000415
        + minor additions to beterm entry (feedback from Rico Tudor) -TD
        + corrections/updates for some IBM terminfo entries -TD
        + modify _nc_screen_wrap() so that when exiting curses mode with
          non-default colors, the last line on the screen will be cleared to
          the screen's default colors (request by Alexander V Lukyanov).
        + modify ncurses.c 'r' example to set nonl(), allowing control/M to be
          read for demonstrating the REQ_NEW_LINE operation (prompted by a
          question by Tony L Keith <tlkeith@keithconsulting.com>).
        + modify ncurses.c 'r' example of field_info() to work on Solaris 2.7,
          documented extension of ncurses which allows a zero pointer.
        + modify fmt_complex() to avoid buffer overflow in case of excess
          recursion, and to recognize "%e%?" as a synonym for else-if, which
          means that it will not recur for that special case.
        + add logic to support $TERMCAP variable in case the USE_GETCAP symbol
          is defined (patch by Todd C Miller).
        + modify one of the m4 files used to generate the Ada95 sources,
          to avoid using the token "symbols" (patch by Juergen Pfeifer).

20000408
        + add terminfo entries bsdos-pc-m, bsdos-pc-mono (Jeffrey C Honig)
        + correct spelling error in terminfo entry name:  bq300-rv was given as
          bg300-rv in esr's version.
        + modify redrawwin() macro so its parameter is fully parenthesized
          (fixes Debian #61088).
        + correct formatting error in dump_entry() which set incorrect column
          value when no newline trimming was needed at the end of an entry,
          before appending "use=" clauses (cf: 960406).

20000401
        + add configure option --with-manpage-symlinks
        + change unctrl() to render C1 characters (128-159) as ~@, ~A, etc.
        + change makefiles so trace() function is provided only if TRACE is
          defined, e.g., in the debug library.  Modify related calls to
          _tracechar() to use unctrl() instead.

20000325
        + add screen's AX capability (for ECMA SGR 39 and 49) to applicable
          terminfo entries, use presence of this as a check for a small
          improvement in setting default colors.
        + improve logic in _nc_do_color() implementing assume_default_colors()
          by passing in previous color pair info to eliminate redundant call to
          set_original_colors().  (Part of this is from a patch by Alexander
          V Lukyanov).
        + modify warning in _nc_trans_string() about a possibly too-long string
          to do this once only rather than for each character past the
          threshold (600).  Change interface of _nc_trans_string() to allow
          check for buffer overflow.
        + correct use of memset in _nc_read_entry_source() to initialize ENTRY
          struct each time before reading new data into it, rather than once
          per loop (cf:  990301).  This affects multi-entry in-core operations
          such as "infocmp -Fa".

20000319
        + remove a spurious pointer increment in _nc_infotocap() changes from
          20000311.  Add check for '.' in format of number, since that also
          is not permitted in termcap.
        + correct typo in rxvt-basic terminfo from temporary change made while
          integrating 20000318.

20000318
        + revert part of the vt220 change (request by Todd C Miller).
        + add ansi-* terminfo entries from ESR's version.
        + add -a option to tic and infocmp, which retains commented-out
          capabilities during source translation/comparison, e.g., captoinfo
          and infotocap.
        + modify cardfile.c to display an empty card if no input data file is
          found, fixes a core dump in that case (reported by Bruno Haible).
        + correct bracketing in CF_MATH_LIB configure macro, which gave wrong
          result for OS/2 EMX.
        + supply required parameter for _nc_resolve_uses() call in
          read_termcap.c, overlooked in 20000311 (reported by Todd C Miller).
        > patches by Bruno Haible <haible@ilog.fr>:
        + fix a compiler warning in fty_enum.c
        + correct LIB_PREFIX expression for DEPS_CURSES in progs, tack
          makefiles, which resulted in redundant linking (cf: 20000122).

20000311
        + make ifdef's for BROKEN_LINKER consistent (patch by Todd C Miller).
        + improved tack/README (patch by Daniel Weaver).
        + modify tput.c to ensure that unspecified parameters are passed to
          tparm() as 0's.
        + add a few checks in infocmp to guard against buffer overflow when
          displaying string capabilities.
        + add check for zero-uses in infocmp's file_comparison() function
          before calling _nc_align_termtype().  Otherwise one parameter is
          indexed past the end of the uses-array.
        + add an option -q to infocmp to specify the less verbose output,
          keeping the existing format as the default, though not retaining the
          previous behavior that made the -F option compare each entry to
          itself.
        + adapted patch by ESR to make infocmp -F less verbose -TD
          (the submitted patch was unusable because it did not compile
          properly)
          + modify write_entry.c to ensure that absent or cancelled booleans
            are written as FALSE, for consistency with infocmp which now
            assumes this.  Note that for the small-core configuration, tic
            may not produce the same result as before.
          + change some private library interfaces used by infocmp, e.g.,
            _nc_resolve_uses().
          + add a check in _nc_infotocap() to ensure that cm-style capabilities
            accept only %d codes when converting the format from terminfo to
            termcap.
          + modify ENTRY struct to separate the data in 'parent' into the name
            and link values (the original idea to merge both into 'parent' was
            not good).
          + discard repair_acsc(tterm);
        > patch by Juergen Pfeifer:
        + drop support for gnat 3.10
        + move generated documentation and html files under ./doc directory,
          adding makefile rules for this to dist.mk

20000304
        + correct conflicting use of tparm() in 20000226 change to tic, which
          made it check only one entry at a time.
        + fix errors in ncurses-intro.html and hackguide.html shown by Dave
          Raggett's tidy.
        + make the example in ncurses-intro.html do something plausible, and
          corrected misleading comment (reported by Neil Zanella).
        + modify pnoutrefresh() to set newscr->_leaveok as wnoutrefresh() does,
          to fix a case where the cursor position was not updated as in
          Solaris  (patch by David Mosberger <davidm@hpl.hp.com>).
        + add a limit-check for wresize() to ensure that a subwindow does not
          address out of bounds.
        + correct offsets used for subwindows in wresize() (patch by Michael
          Andres <ma@suse.de>).
        + regenerate html'ized manual pages with man2html 3.0.1 (patch by
          Juergen Pfeifer).  This generated a file with a space in its name,
          which I removed.
        + fix a few spelling errors in tack.
        + modify tack/Makefile.in to match linker options of progs/Makefile.in;
          otherwise it does not build properly for older HPUX shared library
          configurations.
        + add several terminfo entries from esr's "11.0".

20000226
        + make 'tput flash' work properly for xterm by flushing output in
          delay_output() when using napms(), and modifying xterm's terminfo to
          specify no padding character.  Otherwise, xterm's reported baud rate
          can mislead ncurses into producing too few padding characters
          (Debian #58530).
        + add a check to tic for consistency between sgr and the separate
          capabilities such as smso, use this to check/correct several
          terminfo entries (Debian #58530).
        + add a check to tic if cvvis is the same as cnorm, adjusted several
          terminfo entries to remove the conflict (Debian #58530).
        + correct prototype shown in attr_set()/wattr_set() manpages (fixes
          Debian #53962).
        + minor clarification for curs_set() and leaveok() manpages.
        + use mkstemp() for creating temporary file for tic's processing of
          $TERMCAP contents (fixes Debian #56465).
        + correct two errors from integrating Alexander's changes:  did not
          handle the non-bce case properly in can_erase_with() (noted by
          Alexander), and left fg/bg uninitialized in the pair-zero case of
          _nc_do_color() (reported by Dr Werner Fink <werner@suse.de> and
          Ismael Cordeiro <ismael@cordeiro.com>).

20000219
        + store default-color code consistently as C_MASK, even if given as
          -1 for convenience (adapted from patches by Alexander V Lukyanov).
        > patches by Alexander V Lukyanov:
        + change can_clear_with() macro to accommodate logic for
          assume_default_colors(), making most of the FILL_BCE logic
          unnecessary.  Made can_clear_with() an inline function to make it
          simpler to read.

20000212
        + corrected form of recent copyright dates.
        + minor corrections to xterm-xf86-v333 terminfo entry -TD
        > patches by Alexander V Lukyanov:
        + reworded dft_fgbg.3x to avoid assuming that the terminal's default
          colors are white on black.
        + fix initialization of tstLine so that it is filled with current blank
          character in any case.  Previously it was possible to have it filled
          with old blank.  The wrong over-optimization was introduced in 991002
          patch.  (it is not very critical as the only bad effect is not using
          clr_eos for clearing if blank has changed).

20000205
        + minor corrections/updates to several terminfo entries: rxvt-basic,
          vt520, vt525, ibm5151, xterm-xf86-v40 -TD
        + modify ifdef's for poll() to allow it to use <sys/poll.h>, thereby
          allowing poll() to be used on Linux.
        + add CF_FUNC_POLL macro to check if poll() is able to select from
          standard input.  If not we will not use it, preferring select()
          (adapted from patch by Michael Pakovic <mpakovic@fdn.com>).
        + update CF_SHARED_OPTS macro for SCO Unixware 7.1 to allow building
          shared libraries (reported/tested by Thanh <thanhma@mediaone.net>).
        + override $LANGUAGE in build to avoid incorrect ordering of keynames.
        + correct CF_MATH_LIB parameter, must be sin(x), not sqrt(x).

20000122
        + resync CF_CHECK_ERRNO and CF_LIB_PREFIX macros from tin and xterm -TD
        + modify CF_MATH_LIB configure macro to parameterize the test function
          used, for reuse in dialog and similar packages.
        + correct tests for file-descriptors in OS/2 EMX mouse support.  A
          negative value could be used by FD_SET, causing the select() call
          to wait indefinitely.

20000115
        + additional fixes for non-bce terminals (handling of delete_character)
          to work when assume_default_colors() is not specified.
        + modify warning message from _nc_parse_entry() regarding extended
          capability names to print only if tic/infocmp/toe have the -v flag
          set, and not at all in ordinary user applications.  Otherwise, this
          warning would be shown for screen's extended capabilities in programs
          that use the termcap interface (reported by Todd C Miller).
        + modify use of _nc_tracing from programs such as tic so their debug
          level is not in the same range as values set by trace() function.
        + small panel header cleanup (patch by Juergen Pfeifer).
        + add 'railroad' demo for termcap interface.
        + modify 'tic' to write its usage message to stderr (patch by Todd C
          Miller).

20000108
        + add prototype for erase() to curses.h.in, needed to make test
          programs build with c++/g++.
        + add .c.i and .c.h suffix rules to generated makefiles, for debugging.
        + correct install rule for tack.1; it assumed that file was in the
          current directory (reported by Mike Castle <dalgoda@ix.netcom.com>).
        + modify terminfo/termcap translation to suppress acsc before trying
          sgr if the entry would be too large (patch by Todd C Miller).
        + document a special case of incompatibility between ncurses 4.2 and
          5.0, add a section for this in INSTALL.
        + add TRACE_DATABASE flag for trace().

20000101
        + update mach, add mach-color terminfo entries based on Debian diffs
          for ncurses 5.0 -TD
        + add entries for xterm-hp, xterm-vt220, xterm-vt52 and xterm-noapp
          terminfo entries -TD
        + change OTrs capabilities to rs2 in terminfo.src -TD
        + add obsolete and extended capabilities to 'screen' terminfo -TD
        + corrected conversion from terminfo rs2 to termcap rs (cf: 980704)
        + make conversion to termcap ug (underline glitch) more consistently
          applied.
        + fix out-of-scope use of 'personal[]' buffer in 'toe' (this error
          was in the original pre-1.9.7 version, when $HOME/.terminfo was
          introduced).
        + modify 'toe' to ignore terminfo directories to which it has no
          permissions.
        + modify read_termtype(), fixing 'toe', which could dump core when it
          found an incomplete entry such as "dumb" because it did not
          initialize its buffer for _nc_read_file_entry().
        + use -fPIC rather than -fpic for shared libraries on Linux, not
          needed for i386 but some ports (from Debian diffs for 5.0) -TD
        + use explicit VALID_NUMERIC() checks in a few places that had been
          overlooked, and add a check to ensure that init_tabs is nonzero,
          to avoid divide-by-zero (reported by Todd C Miller).
        + minor fix for CF_ANSI_CC_CHECK configure macro, for HPUX 10.x (from
          tin) -TD

19991218
        + reorder tests during mouse initialization to allow for gpm to run in
          xterm, or for xterm to be used under OS/2 EMX.  Also drop test for
          $DISPLAY in favor of kmous=\E[M or $TERM containing "xterm" (report
          by Christian Weisgerber <naddy@mips.rhein-neckar.de>).
        + modify raw() and noraw() to clear/restore IEXTEN flag which affects
          stty lnext on systems such as FreeBSD (report by Bruce Evans
          <bde@zeta.org.au>, via Jason Evans <jasone@canonware.com>).
        + fix a potential (but unlikely) buffer overflow in failed() function
          of tset.c (reported by Todd C Miller).
        + add manual-page for ncurses extensions, documented curses_version(),
          use_extended_names().

19991211
        + treat as untranslatable to termcap those terminfo strings which
          contain non-decimal formatting, e.g., hexadecimal or octal.
        + correct commented-out capabilities that cannot be translated to
          termcap, which did not check if a colon must be escaped.
        + correct termcap translation for "%>" and "%+", which did not check
          if a colon must be escaped, for instance.
        + use save_string/save_char for _nc_captoinfo() to eliminate fixed
          buffer (originally for _nc_infotocap() in 960301 -TD).
        + correct expression used for terminfo equivalent of termcap %B,
          adjust regent100 entry which uses this.
        + some cleanup and commenting of ad hoc cases in _nc_infotocap().
        + eliminate a fixed-buffer in tic, used for translating comments.
        + add manpage for infotocap

19991204
        + add kvt and gnome terminfo entries -TD
        + correct translation of "%%" by infotocap, which was emitted as "%".
        + add "obsolete" termcap strings to terminfo.src
        + modify infocmp to default to showing obsolete capabilities rather
          than terminfo only.
        + modify write_entry.c so that if extended names (i.e., configure
          --enable-tcap-names) are active, then tic will also write "obsolete"
          capabilities that are present in the terminfo source.
        + modify tic so that when running as captoinfo or infotocap, it
          initializes the output format as in -C and -I options, respectively.
        + improve infocmp and tic -f option by splitting long strings that do
          not have if-then-else construct, but do have parameters, e.g., the
          initc for xterm-88color.
        + refine MKtermsort.sh slightly by using bool for the *_from_termcap
          arrays.

19991127
        + additional fixes for non-bce terminals (handling of clear_screen,
          clr_eol, clr_eos, scrolling) to work when assume_default_colors() is
          not specified.
        + several small changes to xterm terminfo entries -TD.
        + move logic for _nc_windows in lib_freeall.c inside check for nonnull
          SP, since it is part of that struct.
        + remove obsolete shlib-versions, which was unintentionally re-added
          in 970927.
        + modify infocmp -e, -E options to ensure that generated fallback.c
          type for Booleans agrees with term.h (reported by Eric Norum
          <eric@cls.usask.ca>).
        + correct configure script's use of $LIB_PREFIX, which did not work
          for installing the c++ directory if $libdir did not end with "/lib"
          (reported by Huy Le <huyle@ugcs.caltech.edu>).
        + modify infocmp so -L and -f options work together.
        + modify the initialization of SP->_color_table[] in start_color() so
          that color_content() will return usable values for COLORS greater
          than 8.
        + modify ncurses 'd' test in case COLORS is greater than 16, e.g., for
          xterm-88color, to limit the displayed/computed colors to 16.
        > patch by Juergen Pfeifer:
        + simplify coding of the panel library according to suggestions by
          Philippe Blain.
        + improve macro coding for a few macros in curses.priv.h

19991113
        + modify treatment of color pair 0 so that if ncurses is configured
          to support default colors, and they are not active, then ncurses
          will set that explicitly, not relying on orig_colors or orig_pair.
        + add new extension, assume_default_colors() to provide better control
          over the use of default colors.
        + modify test programs to use more-specific ifdef's for existence of
          wresize(), resizeterm() and use_default_colors().
        + modify configure script to add specific ifdef's for some functions
          that are included when --enable-ext-funcs is in effect, so their
          existence can be ifdef'd in the test programs.
        + reorder some configure options, moving those extensions that have
          evolved from experimental status into a new section.
        + change configure --enable-tcap-names to enable this by default.

19991106
        + install tack's manpage (reported by Robert Weiner
          <robert@progplus.com>)
        + correct worm.c's handling of KEY_RESIZE (patch by Frank Heckenbach).
        + modify curses.h.in, undef'ing some symbols to avoid conflict with C++
          STL (reported by Matt Gerassimoff <mgeras@ticon.net>)

19991030
        + modify linux terminfo entry to indicate that dim does not mix with
          color (reported by Klaus Weide <kweide@enteract.com>).
        + correct several typos in terminfo entries related to missing '['
          in CSI's -TD
        + fix several compiler warnings in c++ binding (reported by Tim
          Mooney for alphaev56-dec-osf4.0f
        + rename parameter of _nc_free_entries() to accommodate lint.
        + correct lint rule for tack, used incorrect list of source files.
        + add case to config.guess, config.sub for Rhapsody.
        + improve configure tests for libg++ and libstdc++ by omitting the
          math library (which is missing on Rhapsody), and improved test for
          the math library itself (adapted from path by Nelson H. F. Beebe).
        + explicitly initialize to zero several data items which were
          implicitly initialized, e.g., cur_term.  If not explicitly
          initialized, their storage type is C (common), and causes problems
          linking on Rhapsody 5.5 using gcc 2.7.2.1 (reported by Nelson H. F.
          Beebe).
        + modify Ada95 binding to not include the linker option for Ada
          bindings in the Ada headers, but in the Makefiles instead (patch by
          Juergen Pfeifer).

19991023 5.0 release for upload to ftp.gnu.org
        + effective with release of 5.0, change NCURSES_VERSION_PATCH to
          4-digit year.
        + add function curses_version(), to return ncurses library version
          (request by Bob van der Poel).
        + remove rmam, smam from cygwin terminfo entry.
        + modify FreeBSD cons25 terminfo entry to add cnorm and cvvis, as well
          as update ncv to indicate that 'dim' conflicts with colors.
        + modify configure script to use symbolic links for FreeBSD shared
          libraries by default.
        + correct ranf() function in rain and worm programs to ensure it does
          not return 1.0
        + hide the cursor in hanoi.c if it is running automatically.
        + amend lrtest.c to account for optimizations that exploit margin
          wrapping.
        + add a simple terminfo demo, dots.c
        + modify SIGINT/SIGQUIT handler to set a flag used in _nc_outch() to
          tell it to use write() rather than putc(), since the latter is not
          safe in a signal handler according to POSIX.
        + add/use internal macros _nc_flush() and NC_OUTPUT to hide details
          of output-file pointer in ncurses library.
        + uncomment CC_SHARED_OPTS (see 971115), since they are needed for SCO
          OpenServer.
        + correct CC_SHARED_OPTS for building shared libraries for SCO
          OpenServer.
        + remove usleep() from alternatives in napms(), since it may interact
          with alarm(), causing a process to be interrupted by SIGALRM (with
          advice from Bela Lubkin).
        + modify terminal_interface-curses-forms.ads.m4 to build/work with
          GNAT 3.10 (patch by Juergen Pfeifer).
        + remove part of CF_GPP_LIBRARY configure-script macro, which did not
          work with gcc 2.7.2.3
        + minor fix to test/tclock.c to avoid beeping more than once per second
        + add 's' and ' ' decoding to test/rain.c

991016  pre-release
        + corrected BeOS code for lib_twait.c, making nodelay() function work.

991009  pre-release
        + correct ncurses' value for cursor-column in PutCharLR(), which was
          off-by-one in one case (patch by Ilya Zakharevich).
        + fix some minor errors in position_check() debugging code, found while
          using this to validate the PutCharLR() patch.
        + modify firework, lrtest, worm examples to be resizable, and to
          recognize 'q' for quit, 's' for single-step and ' ' for resume.
        + restore reverted change to  terminal_interface-curses-forms.ads.m4,
          add a note on building with gnat 3.10p to Ada95/TODO.
        + add a copy of the standalone configure script for the test-directory
          to simplify testing on SCO and Solaris.

991002  pre-release
        + minor fixes for _nc_msec_cost(), color_content(), pair_content(),
          _nc_freewin(), ClrBottom() and onscreen_mvcur() (analysis by Philippe
          Blain, comments by Alexander V Lukyanov).
        + simplify definition of PANEL and eliminate internal functions
          _nc_calculate_obscure(), _nc_free_obscure() and _nc_override(),
          (patch by Juergen Pfeifer, analysis by Philippe Blain
          <bledp@voila.fr>)).
        + change renaming of dft_fgbg.3x to use_default_colors.3ncurses in
          man_db.renames, since Debian is not concerned with 14-character
          filename limitation (Debian bug report by Josip Rodin
          <joy@cibalia.gkvk.hr>).
        + corrected scoansi terminfo entry by testing with scoterm and console.
        + revert change from 990614 to terminal_interface-curses-forms.ads.m4,
          since this does not work for gnat 3.10p
        + modify tclock example to be resizable (if ncurses' sigwinch handler
          is used), and in color.
        + use $(CC) rather than 'gcc' in MK_SHARED_LIB symbols, used for Linux
          shared library rules.

990925  pre-release
        + add newer NetBSD console terminfo entries
        + add amiga-8bit terminfo entry (from Henning 'Faroul' Peters
          <Faroul@beyond.kn-bremen.de>)
        + remove -lcurses -ltermcap from configure script's check for the gpm
          library, since they are not really necessary (a properly configured
          gpm library has no dependency on any curses library), and if the
          curses library is not installed, this would cause the test to fail.
        + modify tic's -C option so that terminfo "use=" clauses are translated
          to "tc=" clauses even when running it as captoinfo.
        + modify CF_STDCPP_LIBRARY configure macro to perform its check only
          for GNU C++, since that library conflicts with SGI's libC on IRIX-6.2
        + modify CF_SHARED_OPTS configure macro to support build on NetBSD with
          ELF libraries (patch by Bernd Ernesti <bernd@arresum.inka.de>).
        + correct a problem in libpanel, where the _nc_top_panel variable was
          not set properly when bottom_panel() is called to hide a panel which
          is the only one on the stack (report/analysis by Michael Andres
          <ma@suse.de>, patch by Juergen Pfeifer).

990918  pre-release
        + add acsc string to HP 70092 terminfo entry (patch by Joerg Wunsch
          <j@interface-business.de>).
        + add top-level uninstall.data and uninstall.man makefile rules.
        + correct logic of CF_LINK_FUNCS configure script, from BeOS changes so
          that hard-links work on Unix again.
        + change default value of cf_cv_builtin_bool to 1 (suggested by
          Jeremy Buhler), making it less likely that a conflicting declaration
          of bool will be seen when compiling with C++.

990911  pre-release
        + improved configure checks for builtin.h
        + minor changes to C++ binding (remove static initializations, and make
          configure-test for parameter initializations) for features not
          allowed by vendor's C++ compilers (reported by Martin Mokrejs, this
          applies to SGI, though I found SCO has the same characteristics).
        + corrected quoting of ETIP_xxx definitions which support old versions
          of g++, e.g., those using -lg++
        + remove 'L' code from safe_sprintf.c, since 'long double' is not
          widely portable.  safe_sprintf.c is experimental, however, and
          exists mainly as a fallback for systems without snprintf (reported
          by Martin Mokrejs <mmokrejs@natur.cuni.cz>, for IRIX 6.2)
        + modify definition of _nc_tinfo_fkeys in broken-linker configuration
          so that it is not unnecessarily made extern (Jeffrey C Honig).

990904  pre-release
        + move definition for builtin.h in configure tests to specific check
          for libg++, since qt uses the same filename incompatibly.
        + correct logic of lib_termcap.c tgetstr function, which did not copy
          the result to the buffer parameter.  Testing shows Solaris does
          update this, though of course tgetent's buffer is untouched (reported
          in Peter Edwards <peter.edwards@ireland.com> in
          mpc.lists.freebsd.current newsgroup.
        + corrected beterm terminfo entry, which lists some capabilities which
          are not actually provided by the BeOS Terminal.
        + add special logic to replace select() calls on BeOS, whose select()
          function works only for sockets.
        + correct missing escape in mkterm.h.awk.in, which caused part
          of the copyright noticed to be omitted (reported by Peter
          Wemm <peter@netplex.com.au>).
        > several small changes to make the c++ binding and demo work on OS/2
          EMX (related to a clean reinstall of EMX):
        + correct library-prefix for c++ binding; none is needed.
        + add $x suffix to make_hash and make_keys so 'make distclean' works.
        + correct missing $x suffix for tack, c++ demo executables.
        + split CF_CXX_LIBRARY into CF_GPP_LIBRARY (for -lg++) and
          CF_STDCPP_LIBRARY (for -lstdc++)

990828  pre-release
        + add cygwin terminfo entry -TD
        + modify CF_PROG_EXT configure macro to set .exe extension for cygwin.
        + add configure option --without-cxx-binding, modifying the existing
          --without-cxx option to check only for the C++ compiler
          characteristics.  Whether or not the C++ binding is needed, the
          configure script checks for the size/type of bool, to make ncurses
          match.  Otherwise C++ applications cannot use ncurses.

990821  pre-release
        + updated configure macros CF_MAKEFLAGS, CF_CHECK_ERRNO
        + minor corrections to beterm terminfo entry.
        + modify lib_setup.c to reject values of $TERM which have a '/' in
          them.
        + add ifdef's to guard against CS5, CS6, CS7, CS8 being zero, as more
          than one is on BeOS.  That would break a switch statement.
        + add configure macro CF_LINK_FUNCS to detect and work around BeOS's
          nonfunctional link().
        + improved configure macros CF_BOOL_DECL and CF_BOOL_SIZE to detect
          BeOS's bool, which is declared as an unsigned char.

990814  pre-release
        + add ms-vt100 terminfo entry -TD
        + minor fixes for misc/emx.src, based on testing with tack.
        + minor fix for test/ncurses.c, test 'a', in case ncv is not set.

990731  pre-release
        + minor correction for 'screen' terminfo entry.
        + clarify description of errret values for setupterm in manpage.
        + modify tput to allow it to emit capabilities for hardcopy terminals
          (patch by Goran Uddeborg <goeran@uddeborg.pp.se>).
        + modify the 'o' (panel) test in ncurses.c to show the panels in color
          or at least in bold, to test Juergen's change to wrefresh().
        > patches by Juergen Pfeifer:
        + Fixes a problem using wbkgdset() with panels.  It has actually
          nothing to with panels but is a problem in the implementation of
          wrefresh().  Whenever a window changes its background attribute to
          something different than newscr's background attribute, the whole
          window is touched to force a copy to newscr.  This is an unwanted
          side-effect of wrefresh() and it is actually not necessary.  A
          changed background attribute affects only further outputs of
          background it doesn't mean anything to the current content of the
          window.  So there is no need to force a copy.  (reported by Frank
          Heckenbach <frank@g-n-u.de>).
        + an upward compatible enhancement of the NCursesPad class in the C++
          binding.  It allows one to add a "viewport" window to a pad and then
          to use panning to view the pad through the viewport window.

990724  pre-release
        + suppress a call to def_prog_mode() in the SIGTSTP handler if the
          signal was received while not in curses mode, e.g., endwin() was
          called in preparation for spawning a shell command (reported by Frank
          Heckenbach <frank@g-n-u.de>)
        + corrected/enhanced xterm-r5, xterm+sl, xterm+sl-twm terminfo entries.
        + change test for xterm mouse capability:  it now checks only if the
          user's $DISPLAY variable is set in conjunction with the kmous
          capability being present in the terminfo.  Before, it checked if any
          of "xterm", "rxvt" or "kterm" were substrings of the terminal name.
          However, some emulators which are incompatible with xterm in other
          ways do support the xterm mouse capability.
        + reviewed and made minor changes in ncurses to quiet g++ warnings
          about shadowed or uninitialized variables.  g++ incorrectly warns
          about uninitialized variables because it does not take into account
          short-circuit expression evaluation.
        + change ncurses 'b' test to start in color pair 0 and to show in the
          right margin those attributes which are suppressed by no_color_video,
          i.e., "(NCV)".
        + modify ifdef's in curses.h so that __attribute__ is not redefined
          when compiling with g++, but instead disabled the macros derived for
          __attribute__ since g++ does not consistently recognize the same
          keywords as gcc (reported by Stephan K Zitz <zitz@erf.net>).
        + update dependencies for term.h in ncurses/modules (reported by
          Ilya Zakharevich).

990710  pre-release
        + modify the form demo in ncurses.c to illustrate how to manipulate the
          field appearance, e.g, for highlighting or translating the field
          contents.
        + correct logic in write_entry from split-out of home_terminfo in
          980919, which prevented update of $HOME/.terminfo (reported by Philip
          Spencer <pspencer@fields.utoronto.ca>).

990703  pre-release
        + modify linux terminfo description to make use of kernel 2.2.x mods
          that support cursor style, e.g., to implement cvvis (patch by Frank
          Heckenbach <frank@g-n-u.de>)
        + add special-case in setupterm to retain previously-saved terminal
          settings in cur_term, which happens when curses and termcap calls are
          mixed (from report by Bjorn Helgaas <helgaas@dhc.net>).
        + suppress initialization of key-tries in _nc_keypad() if we are only
          disabling keypad mode, e.g., in endwin() called when keypad() was
          not.
        + modify the Ada95 makefile to ensure that always the Ada files from
          the development tree are used for building and not the eventually
          installed ones (patch by Juergen Pfeifer).

990626  pre-release
        + use TTY definition in tack/sysdep.c rather than struct termios
          (reported by Philippe De Muyter).
        + add a fallback for strstr, used in lib_mvcur.c and tack/edit.c,
          not present on sysV68 (reported by Philippe De Muyter).
        + correct definition in comp_hash.c to build with configure
          --with-rcs-ids option.

990619  pre-release
        + modified ifdef's for sigaction and sigvec to ensure we do not try to
          handle SIGTSTP if neither is available (from report by Philippe De
          Muyter).
        > patch by Philippe De Muyter:
        + in tic.c, use `unlink' if `remove' is not available.
        + use only `unsigned' as fallback value for `speed_t'.  Some files used
          `short' instead.

990616  pre-release
        + fix some compiler warnings in tack.
        + add a check for predefined bool type in CC, based on report that
          BeOS predefines a bool type.
        + correct logic for infocmp -e option, i.e., the configure
          --with-fallbacks option, which I'd not updated when implementing
          extended names (cf:  990301).  The new implementation adds a "-E"
          option to infocmp -TD
        > patch by Juergen Pfeifer:
        + introduce the private type Curses_Bool in the Ada95 binding
          implementation.  This is to clearly represent the use of "bool" also
          in the binding.  It should have no effect on the generated code.
        + improve the man page for field_buffer() to tell the people, that the
          whole buffer including leading/trailing spaces is returned.  This is
          a common source of confusion, so it's better to document it clearly.

990614  pre-release
        > patch by Juergen Pfeifer:
        + use pragma PreElaborate in several places.
        + change a few System.Address uses to more specific types.
        + change interface version-number to 1.0
        + regenerate Ada95 HTML files.

990612  pre-release
        + modify lib_endwin.c to avoid calling reset_shell_mode(), return ERR
          if it appears that curses was never initialized, e.g., by initscr().
          For instance, this guards against setting the terminal modes to
          strange values if endwin() is called after setupterm().  In the same
          context, Solaris curses will dump core.
        + modify logic that avoids a conflict in lib_vidattr.c between sgr0 and
          equivalent values in rmso or rmul by ensuring we do not modify the
          data which would be returned by the terminfo or termcap interfaces
          (reported by Brad Pepers <brad@linuxcanada.com>, cf:  960706).
        + add a null-pointer check for SP in lib_vidattr.c to logic that checks
          for magic cookies.
        + improve fallback declaration of 'bool' when the --without-cxx option
          is given, by using a 'char' on i386 and related hosts (prompted by
          discussion with Alexander V Lukyanov).

990605  pre-release
        + include time.h in lib_napms.c if nanosleep is used (patch by
          R Lindsay Todd <toddr@rpi.edu>).
        + add an "#undef bool" to curses.h, in case someone tries to define it,
          e.g., perl.
        + add check to tparm to guard against divide by zero (reported by Aaron
          Campbell <aaron@ug.cs.dal.ca>).

990516  pre-release
        + minor fix to build tack on CLIX (mismatched const).
        > patch by Juergen Pfeifer:
        + change Juergen's old email address with new one in the files where it
          is referenced.  The Ada95 HTML pages are regenerated.
        + update MANIFEST to list the tack files.

990509  pre-release
        + minor fixes to make 'tack' build/link on NeXT (reported by Francisco
          A. Tomei Torres).

990417  pre-release
        + add 'tack' program (which is GPL'd), updating it to work with the
          modified TERMTYPE struct and making a fix to support setaf/setab
          capabilities.  Note that the tack program is not part of the
          ncurses libraries, but an application which can be distributed with
          ncurses.  The configure script will ignore the directory if it is
          omitted, however.
        + modify gpm mouse support so that buttons 2 and 3 are used for
          select/paste only when shift key is pressed, making them available
          for use by an application (patch by Klaus Weide).
        + add complete list of function keys to scoansi terminfo entry - TD

990410  pre-release
        + add a simple test program cardfile.c to illustrate how to read form
          fields, and showing forms within panels.
        + change shared-library versioning for the Hurd to be like Linux rather
          than *BSD (patch by Mark Kettenis <kettenis@wins.uva.nl>).
        + add linux-lat terminfo entry.
        + back-out _nc_access check in read_termcap.c (both incorrect and
          unnecessary, except to guard against a small window where the file's
          ownership may change).

990403  pre-release
        + remove conflicting _nc_free_termtype() function from test module
          lib_freeall.c
        + use _nc_access check in read_termcap.c for termpaths[] array (noted
          by Jeremy Buhler, indicating that Alan Cox made a similar patch).
        > patch by Juergen Pfeifer:
        + modify menu creation to not inherit status flag from the default menu
          which says that the associated marker string has been allocated and
          should be freed (bug reported by Marek Paliwoda"
          <paliwoda@kki.net.pl>)

990327  pre-release (alpha.gnu.org:/gnu/ncurses-5.0-beta1.tar.gz)
        + minor fixes to xterm-xfree86 terminfo entry - TD.
        + split up an expression in configure script check for ldconfig to
          workaround limitation of BSD/OS sh (reported by Jeff Haas
          <jmh@mail.msen.com>).
        + correct a typo in man/form_hook.3x (Todd C Miller).

990318  pre-release
        + parenthesize and undef 'index' symbol in c++ binding and demo, to
          accommodate its definition on NeXT (reported by Francisco A. Tomei
          Torres).
        + add sigismember() to base/sigaction.c compatibility to link on NeXT
          (reported by Francisco A. Tomei Torres).
        + further refinements to inequality in hashmap.c to cover a case with
          ^U in nvi (patch by Alexander V Lukyanov).

990316  pre-release
        + add fallback definition for getcwd, to link on NeXT.
        + add a copy of cur_term to tic.c to make it link properly on NeXT
          (reported by Francisco A. Tomei Torres).
        + change inequality in hashmap.c which checks the distance traveled by
          a chunk so that ^D command in nvi (scrolls 1/2 screen) will use
          scrolling logic (patch by Alexander V Lukyanov, reported by Jeffrey
          C Honig).

990314  pre-release
        + modify lib_color.c to handle a special case where the curscr
          attributes have been made obsolete (patch by Alexander V Lukyanov).
        + update BSD/OS console terminfo entries to use klone+sgr and
          klone+color (patch by Jeffrey C Honig).
        + update glibc addon configure script for extended capabilities.
        + correct a couple of warnings in the --enable-const configuration.
        + make comp_hash build properly with _nc_strdup(), on NeXT (reported by
          Francisco A. Tomei Torres <francisco.tomei@cwix.com>).

990313  pre-release
        + correct typos in linux-c initc string - TD
        + add 'crt' terminfo entry, update xterm-xfree86 entry - TD
        + remove a spurious argument to tparm() in lib_sklrefr.c (patch by
          Alexander V Lukyanov).

990307  pre-release
        + back-out change to wgetch because it causes a problem with ^Z
          handling in lynx (reported by Kim DeVaughn).

990306  pre-release
        + add -G option to tic and infocmp, to reverse the "-g" option.
        + recode functions in name_match.c to avoid use of strncpy, which
          caused a 4-fold slowdown in tic (cf: 980530).
        + correct a few warnings about sign-extension in recent changes.
        > patch by Juergen Pfeifer:
        + fixes suggested by Jeff Bradbury <jibradbury@lucent.com>:
          + improved parameter checking in new_fieldtype().
          + fixed a typo in wgetch() timeout handling.
          + allow slk_init() to be called per newterm call.  The internal SLK
            state is stored in the SCREEN struct after every newterm() and then
            reset for the next newterm.
          + fix the problem that a slk_refresh() refreshes stdscr if the
            terminal has true SLKs.
        + update HTML documentation for Ada binding.

990301  pre-release
        + remove 'bool' casts from definitions of TRUE/FALSE so that statements
          such as "#if TRUE" work.  This was originally done to allow for a C++
          compiler which would warn of implicit conversions between enum and
          int, but is not needed for g++ (reported by Kim DeVaughn).
        + add use_extended_names() function to allow applications to suppress
          read of the extended capabilities.
        + add configure option --enable-tcap-names to support logic which
          allows ncurses' tic to define new (i.e., extended) terminal
          capabilities.  This is activated by the tic -x switch.  The infocmp
          program automatically shows or compares extended capabilities.
          Note:  This changes the Strings and similar arrays in the TERMTYPE
          struct so that applications which manipulate it must be recompiled.
        + use macros typeMalloc, typeCalloc and typeRealloc consistently
          throughout ncurses library.
        + add _nc_strdup() to doalloc.c.
        + modify define_key() to allow multiple strings to be bound to the
          same keycode.
        + correct logic error in _nc_remove_string, from 990220.
        > patch for Ada95 binding (Juergen Pfeifer):
        + regenerate some of the html documentation
        + minor cleanup in terminal_interface-curses.adb

990220  pre-release
        + resolve ambiguity of kend/kll/kslt and khome/kfnd/kich1 strings in
          xterm and ncsa terminfo entries by removing the unneeded ones.  Note
          that some entries will return kend & khome versus kslt and kfnd, for
          PC-style keyboards versus strict vt220 compatibility - TD
        + add function keybound(), which returns the definition associated with
          a given keycode.
        + modify define_key() to undefine the given string when no keycode is
          given.
        + modify keyok() so it works properly if there is more than one string
          defined for a keycode.
        + add check to tic to warn about terminfo descriptions that contain
          more than one key assigned to the same string.  This is shown only if
          the verbose (-v) option is given.  Moved related logic (tic -v) from
          comp_parse.c into the tic program.
        + add/use _nc_trace_tries() to show the function keys that will be
          recognized.
        + rename init_acs to _nc_init_acs (request by Alexander V Lukyanov).
        > patch for Ada95 binding (Juergen Pfeifer):
        + remove all the *_adabind.c from ncurses, menu and form projects.
          Those little helper routines have all been implemented in Ada and are
          no longer required.
        + The option handling routines in menu and form have been made more
          save.  They now make sure that the unused bits in options are always
          zero.
        + modify configuration scripts to
          + use gnatmake as default compiler name.  This is a safer choice than
            gcc, because some GNAT implementations use other names for the
            compilerdriver to avoid conflicts.
          + use new default installation locations for the Ada files according
            to the proposed GNU Ada filesystem standard (for Linux).
        + simplify the Makefiles for the Ada binding
        + rename ada_include directory to src.

990213
        + enable sigwinch handler by default.
        + disable logic that allows setbuf to be turned off/on, because some
          implementations will overrun the buffer after it has been disabled
          once.

990206
        + suppress sc/rc capabilities from terminal description if they appear
          in smcup/rmcup.  This affects only scrolling optimization, to fix a
          problem reported by several people with xterm's alternate screen,
          though the problem is more general.
        > patch for Ada95 binding (Juergen Pfeifer):
        + removed all pragma Preelaborate() stuff, because the just released
          gnat-3.11p complains on some constructs.
        + fixed some upper/lower case notations because gnat-3.11p found
          inconsistent use.
        + used a new method to generate the HTML documentation of the Ada95
          binding.  This invalidates nearly the whole ./Ada95/html subtree.
          Nearly all current files in this subtree are removed

990130
        + cache last result from _nc_baudrate, for performance (suggested by
          Alexander V Lukyanov).
        + modify ClrUpdate() function to workaround a problem in nvi, which
          uses redrawwin in SIGTSTP handling.  Jeffrey C Honig reported that
          ncurses repainted the screen with nulls before resuming normal
          operation (patch by Alexander V Lukyanov).
        + generalize is_xterm() function a little by letting xterm/rxvt/kterm
          be any substring rather than the prefix.
        + modify lib_data.c to initialize SP.  Some linkers, e.g., IBM's, will
          not link a module if the only symbols exported from the module are
          uninitialized ones (patch by Ilya Zakharevich).  Ilya says that he
          has seen messages claiming this behavior conforms to the standard.)
        + move call on _nc_signal_handler past _nc_initscr, to avoid a small
          window where Nttyb hasn't yet been filled (reported by Klaus Weide).
        + modify lib_tstp.c to block SIGTTOU when handling SIGTSTP, fixes a
          problem where ncurses applications which were run via a shell script
          would hang when given a ^Z.  Also, check if the terminal's process
          group is consistent, i.e., a shell has not taken ownership of it,
          before deciding to save the current terminal settings in the SIGTSTP
          handler (patch by Klaus Weide).
        + correct spelling of ACS_ names in curs_border.3x (reported by Bob van
          der Poel <bvdpoel@kootenay.com>).
        + correct a couple of typos in the macros supporting the configure
          --with-shlib-version option.

990123
        + modify fty_regex.c to compile on HAVE_REGEXPR_H_FUNCS machine (patch
          by Kimio Ishii <ishii@csl.sony.co.jp>).
        + rename BSDI console terminfo entries:  bsdos to bsdos-pc-nobold, and
          bsdos-bold to bsdos-pc (patch by Jeffrey C Honig).
        + modify tput to accept termcap names as an alternative to terminfo
          names (patch by Jeffrey C Honig).
        + correct a typo in term.7 (Todd C Miller).
        + add configure --with-shlib-version option to allow installing shared
          libraries named according to release or ABI versions.  This
          parameterizes some existing logic in the configure script, and is
          intended for compatibility upgrades on Digital Unix, which used
          versioned libraries in ncurses 4.2, but no longer does (cf:  980425).
        + resync configure script against autoconf 2.13 + patches
        + minor improvements for teraterm terminfo entry based on the program's
          source distribution.

990116
        + change default for configure --enable-big-core to assume machines do
          have enough memory to resolve terminfo.src in-memory.
        + correct name of ncurses library in TEST_ARGS when configuring with
          debug library.
        + minor fixes to compile ncurses library with broken-linker with g++.
        + add --enable-broken-linker configure option, default to environment
          variable $BROKEN_LINKER (request by Jeffrey C Honig).
        + change key_names[] array to static since it is not part of the curses
          interface (reported by Jeffrey C Honig <jch@bsdi.com>).

990110
        + add Tera Term terminfo entry - TD

990109
        + reviewed/corrected macros in curses.h as per XSI document.
        + provide support for termcap PC variable by copying it from terminfo
          data and using it as the padding character in tputs (reported by
          Alexander V Lukyanov).
        + corrected iris-ansi and iris-ansi-ap terminfo entries for kent and
          kf9-kf12 capabilities, as well as adding kcbt.
        + document the mouse handling mechanism in menu_driver and make a small
          change in menu_driver's return codes to provide more consistency
          (patch by Juergen Pfeifer).
        + add fallback definition for NCURSES_CONST to termcap.h.in (reported
          by Uchiyama Yasushi <uch@nop.or.jp>).
        + move lib_restart.c to ncurses/base, since it uses curses functions
          directly, and therefore cannot be used in libtinfo.so
        + rename micro_char_size to micro_col_size, adding #define to retain
          old name.
        + add set_a_attributes and set_pglen_inch to terminfo structure, as per
          XSI and Solaris 2.5.
        + minor makefile files to build ncurses test_progs
        + update html files in misc directory to reflect changes since 4.2

990102
        + disable scroll hints when hashmap is enabled (patch by Alexander
          V Lukyanov).
        + move logic for tic's verify of -e option versus -I and -C so that the
          terminfo data is not processed if we cannot handle -e (reported by
          Steven Schwartz <steves@unitrends.com>.
        + add test-driver traces to terminfo and termcap functions.
        + provide support for termcap ospeed variable by copying it from the
          internal cur_term member, and using ospeed as the baudrate reference
          for the delay_output and tputs functions.  If an application does not
          set ospeed, the library behaves as before, except that _nc_timed_wait
          is no longer used, or needed, since ospeed always has a value.  But
          the application can modify ospeed to adjust the output of padding
          characters (prompted by a bug report for screen 3.7.6 and email from
          Michael Schroeder <Michael.Schroeder@informatik.uni-erlangen.de>).
        + removed some unused ifdef's as part of Alexander's restructuring.
        + reviewed/updated curses.h, term.h against X/Open Curses Issue 4
          Version 2.  This includes making some parameters NCURSES_CONST
          rather than const, e.g., in termcap.h.
        + change linux terminfo entry to use ncv#2, since underline does not
          work with color

981226
        + miscellaneous corrections for curses.h to match XSI.
        + change --enable-no-padding configure option to be normally enabled.
        + add section to ncurses manpage for environment variables.
        + investigated Debian bug report that pertains to screen 3.7.4/3.7.6
          changes, found no sign of problems on Linux (or on SunOS, Solaris)
          running screen built with ncurses.
        + check if tmp_fp is opened in tic.c before closing it (patch by Pavel
          Roskin <pavel_roskin@geocities.com>).
        + correct several font specification typos in man-pages.

981220
        + correct default value for BUILD_CC (reported by Larry Virden).

981219
        + modify _nc_set_writedir() to set a flag in _nc_tic_dir() to prevent
          it from changing the terminfo directory after chdir'ing to it.
          Otherwise, a relative path in $TERMINFO would confuse tic (prompted
          by a Debian bug report).
        + correct/update ncsa terminfo entry (report by Larry Virden).
        + update xterm-xfree86 terminfo to current (patch 90), smcur/rmcur
          changes
        + add Mathew Vernon's mach console entries to terminfo.src
        + more changes, moving functions, as part of Alexander's restructuring.
        + modify configure script for GNU/Hurd share-library support, introduce
          BUILD_CC variable for cross compiling (patch by Uchiyama Yasushi
          <uch@nop.or.jp>)

981212
        + add environment variable NCURSES_NO_SETBUF to allow disabling the
          setbuf feature, for testing purposes.
        + correct ifdef's for termcap.h versus term.h that suppress redundant
          declarations of prototypes (reported by H.J.Lu).
        + modify Makefile.os2 to add linker flags which allow multiple copies
          of an application to coexist (reported by Ilya Zakharevich).
        + update Makefile.glibc and associated configure script so that ncurses
          builds as a glibc add-on with the new directory configuration
          (reported by H.J.Lu).

981205
        + modify gen_reps() function in gen.c to work properly on SunOS
          (sparc), which is a left-to-right architecture.
        + modify relative_move and tputs to avoid an interaction with the
          BSD-style padding.  The relative_move function could produce a string
          to replace on the screen which began with a numeric character, which
          was then interpreted by tputs as padding.  Now relative_move will not
          generate a string with a leading digit in that case (overwrite).
          Also, tputs will only interpret padding if the string begins with a
          digit; as coded it permitted a string to begin with a decimal point
          or asterisk (reported by Larry Virden).
        > patches by Juergen Pfeifer:
        + fix a typo in m_driver.c mouse handling and improves the error
          handling.
        + fix broken mouse handling in the Ada95 binding
        + make the Ada95 sample application menus work with the new menu mouse
          support
        + improve the mouse handling introduced by Ilya; it now handles menus
          with spacing.
        + repair a minor bug in the menu_driver code discovered during this
          rework.
        + add new function wmouse_trafo() to hide implementation details of
          _yoffset member of WINDOW struct needed for mouse coordinate
          transformation.

981128
        + modify Ada95/gen/gen.c to avoid using return-value of sprintf, since
          some older implementations (e.g., SunOS 4.x) return the buffer
          address rather than its length.
        > patch by Rick Ohnemus:
        + modify demo.cc to get it to compile with newer versions of egcs.
        + trim a space that appears at the end of the table preprocessor lines
          ('\" t).  This space prevents some versions of man from displaying
          the pages - changed to remove all trailing whitespace (TD)
        + finally, 'make clean' does not remove panel objects.
        > patches by Ilya Zakharevich:
        + allow remapping of OS/2 mouse buttons using environment variable
          MOUSE_BUTTONS_123 with the default value 132.
        + add mouse support to ncurses menus.

981121
        + modify misc/makedef.cmd to report old-style .def file symbols, and to
          generate the .def files sorted by increasing names rather than the
          reverse.
        + add misc/*.ref which are J.J.G.Ripoll's dll definition files (renamed
          from misc/*.old), and updated based on the entrypoint coding he used
          for an older version of ncurses.
        + add README.emx, to document how to build on OS/2 EMX.
        + updates for config.guess, config.sub from Lynx
        > patches by Ilya Zakharevich:
        + minor fixes for mouse handling mode:
          a) Do not initialize mouse if the request is to have no mouse;
          b) Allow switching of OS/2 VIO mouse on and off.
        + modify Makefile.os2 to support alternative means of generating
          configure script, by translating Unix script with Perl.
        > patches by Juergen Pfeifer:
        + Updates MANIFEST to reflect changes in source structure
        + Eliminates a problem introduced with my last patch for the C++
          binding in the panels code.  It removes the update() call done in the
          panel destructor.
        + Changes in the Ada95 binding to better support systems where
          sizeof(chtype)!=sizeof(int) (e.g.  DEC Alpha).

981114
        + modify install-script for manpages to skip over .orig and .rej files
          (request by Larry Virden).
        > patches/discussion by Alexander V Lukyanov:
        + move base-library sources into ncurses/base and tty (serial terminal)
          sources into ncurses/tty, as part of Alexander V Lukyanov's proposed
          changes to ncurses library.
        + copy _tracemouse() into ncurses.c so that lib_tracemse.c need not
          be linked into the normal ncurses library.
        + move macro winch to a function, to hide details of struct ldat
        > patches by Juergen Pfeifer:
        + fix a potential compile problem in cursesw.cc
        + some Ada95 cosmetics
        + fix a gen.c problem when compiling on 64-Bit machines
        + fix Ada95/gen/Makefile.in "-L" linker switch
        + modify Ada95 makefiles to use the INSTALL_PREFIX setting.

981107
        + ifdef'd out lib_freeall.c when not configured.
        + rename _tracebits() to _nc_tracebits().
        + move terminfo-library sources into ncurses/tinfo, and trace-support
          functions into ncurses/trace as part of Alexander V Lukyanov's
          proposed changes to ncurses library.
        + modify generated term.h to always specify its own definitions for
          HAVE_TERMIOS_H, etc., to guard against inclusion by programs with
          broken configure scripts.

981031
        + modify terminfo parsing to accept octal and hexadecimal constants,
          like Solaris.
        + remove an autoconf 2.10 artifact from the configure script's check
          for "-g" compiler options.  (Though harmless, this confused someone
          at Debian, who recently issued a patch that results in the opposite
          effect).
        + add configure option --with-ada-compiler to accommodate installations
          that do not use gcc as the driver for GNAT (patch by Juergen
          Pfeifer).

981017
        + ensure ./man exists in configure script, needed when configuring
          with --srcdir option.
        + modify infocmp "-r" option to remove limit on formatted termcap
          output, which makes it more like Solaris' version.
        + modify captoinfo to treat no-argument case more like Solaris'
          version, which uses the contents of $TERMCAP as the entry to format.
        + modify mk-2nd.awk to handle subdirectories, e.g., ncurses/tty
          (patch by Alexander V Lukyanov).

981010
        + modify --with-terminfo-dirs option so that the default value is the
          ${datadir} value, unless $TERMINFO_DIRS is already set.  This gets
          rid of a hardcoded list of candidate directories in the configure
          script.
        + add some error-checking to _nc_read_file_entry() to ensure that
          strings are properly terminated (Todd C Miller).
        + rename manpage file curs_scr_dmp.3x to curs_scr_dump.3x, to
          correspond with contents (reported by Neil Zanella
          <nzanella@cs.mun.ca>).
        + remove redundant configure check for C++ which did not work when $CXX
          was specified with a full pathname (reported by Andreas Jaeger).
        + corrected bcopy/memmove check; the macro was not standalone.

981003
        + remove unnecessary portion of OS/2 EMX mouse change from
          check_pending() (reported by Alexander V Lukyanov).

980926
        + implement mouse support for OS/2 EMX (adapted from patch against
          4.2(?) by Ilya Zakharevich).
        + add configure-check for bcopy/memmove, for 980919 changes to hashmap.
        + merge Data General terminfo from Hasufin <hasufin@vidnet.net> - TD
        + merge AIX 3.2.5 terminfo descriptions for IBM terminals, replaces
          some older entries - TD
        + modify tic to compile into %'char' form in preference to %{number},
          since that is a little more efficient.
        + minor correction to infocmp to avoid displaying "difference" between
          two capabilities that are rendered in equivalent forms.
        + add "-g" option to tic/infocmp to force character constants to be
          displayed in quoted form.  Otherwise their decimal values are shown.
        + modify setupterm so that cancelled strings are treated the same as
          absent strings, cancelled and absent booleans false (does not affect
          tic, infocmp).
        + modify tic, infocmp to discard redundant i3, r3 strings when output
          to termcap format.
        > patch by Alexander V Lukyanov:
        + improve performance of tparm, now it takes 19% instead of 25% when
          profiling worm.
        + rename maxlen/minlen to prec/width for better readability.
        + use format string for printing strings.
        + use len argument correctly in save_text, and pass it to save_number.

980919
        + make test_progs compile (but hashmap does not function).
        + correct NC_BUFFERED macro, used in lib_mvcur test-driver, modify
          associated logic to avoid freeing the SP->_setbuf data.
        + add modules home_terminfo and getenv_num to libtinfo.
        + move write_entry to libtinfo, to work with termcap caching.
        + minor fixes to blue.c to build with atac.
        + remove softscroll.c module; no longer needed for testing.
        > patches by Todd C Miller:
        + use strtol(3) instead of atoi(3) when parsing env variables so we can
          detect a bogus (non-numeric) value.
        + check for terminal names > MAX_NAME_SIZE in a few more places when
          dealing with env variables again.
        + fix a MAX_NAME_SIZE that should be MAX_NAME_SIZE+1
        + use sizeof instead of strlen(3) on PRIVATE_INFO since it is a fixed
          string #define (compile time vs runtime).
        + when setting errno to ENOMEM, set it right before the return, not
          before code that could, possibly, set errno to a different value.
        > patches by Alexander V Lukyanov:
        + use default background in update_cost_from_blank()
        + disable scroll-hints when hashmap is configured.
        + improve integration of hashmap scrolling code, by adding oldhash and
          newhash data to SP struct.
        + invoke del_curterm from delscreen.
        + modify del_curterm to set cur_term to null if it matches the
          function's parameter which is deleted.
        + modify lib_doupdate to prefer parm_ich to the enter_insert_mode and
          exit_insert_mode combination, adjusting InsCharCost to check
          enter_insert_mode, exit_insert_mode and insert_padding.  Add
          insert_padding in insert mode after each char.  This adds new costs
          to the SP struct.

980912
        + modify test-driver in lib_mvcur.s to use _nc_setbuffer, for
          consistent treatment.
        + modify ncurses to restore output to unbuffered on endwin, and resume
          buffering in refresh (see lib_set_term.c and NC_BUFFERED macro).
        + corrected HTML version numbers (according to the W3C validator, they
          never were HTML 2.0-compliant, but are acceptable 3.0).

980905
        + modify MKterminfo.sh to generate terminfo.5 with tables sorted by
          capability name, as in SVr4.
        + modified term.h, termcap.h headers to avoid redundant declarations.
        + change 'u_int' type in tset.c to unsigned, making this compile on
          Sequent PRX 4.1 (reported by Michael Sterrett <msterret@coat.com>).

980829
        + corrections to mailing addresses, and moving the magic line that
          causes the man program to invoke tbl to the first line of each
          manpage (patch by Rick Ohnemus <rick@ecompcon.com>).
        + add Makefile.os2 and supporting scripts to generate dll's on OS/2 EMX
          (from J.J.G.Ripoll, with further integration by TD).
        + correct a typo in icl6404 terminfo entry.
        + add xtermm and xtermc terminfo entries.
        > from esr's terminfo version:
        + Added Francesco Potorti's tuned Wyse 99 entries.
        + dtterm enacs (from Alexander V Lukyanov).
        + Add ncsa-ns, ncsa-m-ns and ncsa-m entries from esr version.

980822
        + document AT&T acs characters in terminfo.5 manpage.
        + use EMX _scrsize() function if terminfo and environment do not
          declare the screen size (reported by Ilya Zakharevich
          <ilya@math.ohio-state.edu>).
        + remove spurious '\' characters from eterm and osborne terminfo
          entries (prompted by an old Debian bug report).
        + correct reversed malloc/realloc calls in _nc_doalloc (reported by
          Hans-Joachim Widmaier <hjwidmai@foxboro.com>).
        + correct misplaced parenthesis which caused file-descriptor from
          opening termcap to be lost, from 980725 changes (reported by Andreas
          Jaeger).

980815
        + modify lib_setup.c to eliminate unneeded include of <sys/ioctl.h>
          when termios is not used (patch by Todd C Miller).
        + add function _nc_doalloc, to ensure that failed realloc calls do not
          leak memory (reported by Todd C Miller).
        + improved ncsa-telnet terminfo entry.

980809
        + correct missing braces around a trace statement in read_entry.c,
          from 980808 (reported by Kim DeVaughn <kimdv@best.com> and Liviu
          Daia).

980808
        + fix missing include <errno.h> in ditto.c (reported by Bernhard
          Rosenkraenzer <bero@k5.sucks.eu.org>)
        + add NCSA telnet terminfo entries from Francesco Potorti
          <F.Potorti@cnuce.cnr.it>, from Debian bug reports.
        + make handling of $LINES and $COLUMNS variables more compatible with
          Solaris by allowing them to individually override the window size
          as obtained via ioctl.

980801
        + modify lib_vidattr.c to allow for terminal types (e.g., xterm-color)
          which may reset all attributes in the 'op' capability, so that colors
          are set before turning on bold and other attributes, but still after
          turning attributes off.
        + add 'ditto.c' to test directory to illustrate use of newterm for
          initializing multiple screens.
        + modify _nc_write_entry() to recover from failed attempt to link alias
          for a terminfo on a filesystem which does not preserve character case
          (reported by Peter L Jordan <PJordan@chla.usc.edu>).

980725
        + updated versions of config.guess and config.sub based on automake 1.3
        + change name-comparisons in lib_termcap to compare no more than 2
          characters (gleaned from Debian distribution of 1.9.9g-8.8, verified
          with Solaris curses).
        + fix typo in curs_insstr.3x (patch by Todd C Miller)
        + use 'access()' to check if ncurses library should be permitted to
          open or modify files with fopen/open/link/unlink/remove calls, in
          case the calling application is running in setuid mode (request by
          Cristian Gafton <gafton@redhat.com>, responding to Duncan Simpson
          <dps@io.stargate.co.uk>).
        + arm100 terminfo entries from Dave Millen <dmill@globalnet.co.uk>).
        + qnxt2 and minitel terminfo entries from esr's version.

980718
        + use -R option with ldconfig on FreeBSD because otherwise it resets
          the search path to /usr/lib (reported by Dan Nelson).
        + add -soname option when building shared libraries on OpenBSD 2.x
          (request by QingLong).
        + add configure options --with-manpage-format and
          --with-manpage-renames (request by QingLong).
        + correct conversion of CANCELLED_NUMERIC in write_object(), which was
          omitting the high-order byte, producing a 254 in the compiled
          terminfo.
        + modify return-values of tgetflag, tgetnum, tgetstr, tigetflag,
          tigetnum and tigetstr to be compatible with Solaris (gleaned from
          Debian distribution of 1.9.9g-8.8).
        + modify _nc_syserr_abort to abort only when compiled for debugging,
          otherwise simply exit with an error.

980711
        + modify Ada95 'gen' program to use appropriate library suffix (e.g.,
          "_g" for a debug build).
        + update Ada95 'make clean' rule to include generics .ali files
        + add a configure test to ensure that if GNAT is found, that it can
          compile/link working Ada95 program.
        + flush output in beep and flash functions, fixing a problem with
          getstr (patch by Alexander V Lukyanov)
        + fix egcs 1.0.2 warning for etip.h (patch by Chris Johns).
        + correct ifdef/brace nesting in lib_sprintf.c (patch by Bernhard
          Rosenkraenzer <bero@Pool.Informatik.RWTH-Aachen.DE>).
        + correct typo in wattr_get macro from 980509 fixes (patch by Dan
          Nelson).

980704
        + merge changes from current XFree86 xterm terminfo descriptions.
        + add configure option '--without-ada'.
        + add a smart-default for termcap 'ac' to terminfo 'acs_chars' which
          corresponds to vt100.
        + change translation for termcap 'rs' to terminfo 'rs2', which is
          the documented equivalent, rather than 'rs1'.

980627
        + slow 'worm' down a little, for very fast machines.
        + corrected firstchar/lastchar computation in lib_hline.c
        + simplify some expressions with CHANGED_CELL, CHANGED_RANGE and
          CHANGED_TO_EOL macros.
        + modify init_pair so that if a color-pair is reinitialized, we will
          repaint the areas of the screen whose color changes, like SVr4 curses
          (reported by Christian Maurer <maurer@inf.fu-berlin.de>).
        + modify getsyx/setsyx macros to comply with SVr4 man-page which
          says that leaveok() affects their behavior (report by Darryl Miles,
          patch by Alexander V Lukyanov).

980620
        + review terminfo.5 against Solaris 2.6 curses version, corrected
          several minor errors/omissions.
        + implement tparm %l format.
        + implement tparm printf-style width and precision for %s, %d, %x, %o
          as per XSI.
        + implement tparm dynamic variables (reported by Xiaodan Tang).

980613
        + update man-page for for wattr_set, wattr_get (cf:  980509)
        + correct limits in hashtest, which would cause nonprinting characters
          to be written to large screens.
        + correct configure script, when --without-cxx was specified:  the
          wrong variable was used for cf_cv_type_of_bool.  Compilers up to gcc
          2.8 tolerated the missing 'int'.
        + remove the hardcoded name "gcc" for the GNU Ada compiler.  The
          compiler's name might be something like "egcs" (patch by Juergen
          Pfeifer).
        + correct curs_addch.3x, which implied that echochar could directly
          display control characters (patch by Alexander V Lukyanov).
        + fix typos in ncurses-intro.html (patch by Sidik Isani
          <isani@cfht.hawaii.edu>)

980606
        + add configure test for conflicting use of exception in math.h and
          other headers.
        + minor optimization to 'hash()' function in hashmap.c, reduces its
          time by 10%.
        + correct form of LD_SHARED_OPTS for HP-UX 10.x (patch by Tim Mooney).
        + fix missing quotes for 'print' in MKunctrl.awk script (reported by
          Mihai Budiu <mihaib@gs41.sp.cs.cmu.edu>).
        > patch by Alexander V Lukyanov:
        + correct problem on Solaris (with poll() function) where getch could
          hang indefinitely even if timeout(x) was called.  This turned out to
          be because milliseconds was not updated before 'goto retry' in
          _nc_timed_wait.
        + simplified the function _nc_timed_wait and fixed another bug, which
          was the assumption of !GOOD_SELECT && HAVE_GETTIMEOFDAY in *timeleft
          assignment.
        + removed the cycle on EINTR, as it seems to be useless.

980530
        + add makefile-rule for test/keynames
        + modify run_tic.sh and shlib to ensure that user's .profile does not
          override the $PATH used to run tic (patch by Tim Mooney).
        + restore LD_SHARED_OPTS to $(LD_SHARED_FLAGS) when linking programs,
          needed for HP-UX shared-library path (recommended by Tim Mooney).
        + remove special case of HP-UX -L options, use +b options to embed
          $(libdir) in the shared libraries (recommended by Tim Mooney).
        + add checks for some possible buffer overflows and unchecked
          malloc/realloc/calloc/strdup return values (patch by Todd C Miller
          <Todd.Miller@courtesan.com>)

980523
        + correct maxx/maxy expression for num_columns/num_lines in derwin
          (patch by Alexander V Lukyanov).
        + add /usr/share/lib/terminfo and /usr/lib/terminfo as compatibility
          fallbacks to _nc_read_entry(), along with --with-terminfo-dirs
          configure option (suggested by Mike Hopkirk).
        + modify config.guess to recognize Unixware 2.1 and 7 (patch by Mike
          Hopkirk <hops@sco.com>).
        + suppress definition of CC_SHARED_OPTS in LDFLAGS_SHARED in c++
          Makefile.in, since this conflicts when g++ is used with HP-UX
          compiler (reported by Tim Mooney).
        + parenthesize 'strcpy' calls in c++ binding to workaround redefinition
          in some C++ implementations (reported by several people running
          egcs with glibc 2.0.93, analysis by Andreas Jaeger.

980516
        + modify write_entry.c so that it will not attempt to link aliases
          with embedded '/', but give only a warning.
        + put -L$(libdir) first when linking programs, except for HP-UX.
        + modify comp_scan.c to handle SVr4 terminfo description for att477,
          which contains a colon in the description field.
        + modify configure script to support SCO osr5.0.5 shared libraries,
          from comp.unix.sco.programmer newsgroup item (Mike Hopkirk).
        + eliminate extra GoTo call in lib_doupdate.c (patch by Alexander V.
          Lukyanov).
        + minor adjustments of const/NCURSES_CONST from IRIX compile.
        + add updates based on esr's 980509 version of terminfo.src.

980509
        + correct macros for wattr_set, wattr_get, separate wattrset macro from
          these to preserve behavior that allows attributes to be combined with
          color pair numbers.
        + add configure option --enable-no-padding, to allow environment
          variable $NCURSES_NO_PADDING to eliminate non-mandatory padding,
          thereby making terminal emulators (e.g., for vt100) a little more
          efficient (request by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
        + modify configure script to embed ABI in shared libraries for HP-UX
          10.x (detailed request by Tim Mooney).
        + add test/example of the 'filter()' function.
        + add nxterm and xterm-color terminfo description (request by Cristian
          Gafton <gafton@redhat.com>).
        + modify rxvt terminfo description to clear alternate screen before
          switching back to normal screen, for compatibility with applications
          which use xterm (reported by Manoj Kasichainula <manojk@io.com>).
        + modify linux terminfo description to reset color palette (reported
          by Telford Tendys <telford@eng.uts.edu.au>).
        + correction to doupdate, for case where terminal does not support
          insert/delete character.  The logic did not check that there was a
          difference in alignment of changes to old/new screens before
          repainting the whole non-blank portion of the line.  Modified to fall
          through into logic that reduces by the portion which does not differ
          (reported by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
        + minor performance improvement to wnoutrefresh by moving some
          comparisons out of inner loop.

980425
        + modify configure script to substitute NCURSES_CONST in curses.h
        + updated terminfo entries for xterm-xf86-v40, xterm-16color,
          xterm-8bit to correspond to XFree86 3.9Ag.
        + remove restriction that forces ncurses to use setaf/setab if the
          number of colors is greater than 8.  (see 970524 for xterm-16color).
        + change order of -L options (so that $(libdir) is searched first) when
          linking tic and other programs, to workaround HP's linker.
          Otherwise, the -L../lib is embedded when linking against shared
          libraries and the installed program does not run (reported by Ralf
          Hildebrandt).
        + modify configuration of shared libraries on Digital Unix so that
          versioning is embedded in the library, rather than implied by
          links (patch by Tim Mooney).

980418
        + modify etip.h to avoid conflict with math.h on HP-UX 9.03 with gcc
          2.8.1 which redefines 'exception' (reported by Ralf Hildebrandt
          <R.Hildebrandt@tu-bs.de>).
        + correct configure tests in CF_SHARED_OPTS which used $CC value to
          check for gcc, rather than autoconf's $GCC value.  This did not
          work properly if the full pathname of the compiler were given
          (reported by Michael Yount <yount@csf.Colorado.edu>).
        + revise check for compiler options to force ANSI mode since repeating
          an option such as -Aa causes HP's compiler to fail on its own headers
          (reported by Clint Olsen <olsenc@ichips.intel.com>).

980411
        + ifdef'd has_key() and mcprint() as extended functions.
        + modified several prototypes to correspond with 1997 version of
          X/Open Curses (affects ABI since developers have used attr_get).
        + remove spurious trailing blanks in glibc addon-scripts (patch by
          H.J.Lu).
        + insert a few braces at locations where gcc-2.8.x asks to use them to
          avoid ambiguous else's, use -fpic rather than -fPIC for Linux (patch
          by Juergen Pfeifer).

980404
        + split SHLIB_LIST into SHLIB_DIRS/SHLIB_LIST to keep -L options
          before -l to accommodate Solaris' linker (reported by Larry Virden).

980328
        + modify lib_color.c to eliminate dependency on orig_colors and
          orig_pair, since SVr4 curses does not require these either, but
          uses them when they are available.
        + add detailed usage-message to infocmp.
        + correct a typo in att6386 entry (a "%?" which was "?").
        + add -f option to infocmp and tic, which formats the terminfo
          if/then/else/endif so that they are readable (with newlines and
          tabs).
        + fixes for glibc addon scripts (patch by H.J.Lu).

980321
        + revise configure macro CF_SPEED_TYPE so that termcap.h has speed_t
          declared (from Adam J Richter <adam@yggdrasil.com>)
        + remove spurious curs_set() call from leaveok() (J T Conklin).
        + corrected handling leaveok() in doupdate() (patch by Alexander V.
          Lukyanov).
        + improved version of wredrawln (patch by Alexander V. Lukyanov).
        + correct c++/Makefile.in so install target do not have embedded ../lib
          to confuse it (patch by Thomas Graf <graf@essi.fr>).
        + add warning to preinstall rule which checks if the installer would
          overwrite a curses.h or termcap.h that is not derived from ncurses.
          (The recommended configuration for developers who need both is to
          use --disable-overwrite).
        + modify preinstall rule in top-level Makefile to avoid implicit
          use of 'sh', to accommodate Ultrix 4.4 (reported by Joao Palhoto
          Matos <jmatos@math.ist.utl.pt>, patch by Thomas Esser
          <te@informatik.uni-hannover.de>)
        + refine ifdef's for TRACE so that libncurses has fewer dependencies
          on libtinfo when TRACE is disabled.
        + modify configure script so that if the --with-termlib option is used
          to generate a separate terminfo library, we chain it to the ncurses
          library with a "-l" option (reported by Darryl Miles and Ian T.
          Zimmerman).

980314
        + correct limits and window in wredrawln function (reported/analysis by
          Alexander V. Lukyanov).
        + correct sed expression in configure script for --with-fallback
          option (patch by Jesse Thilo).
        + correct some places in configure script where $enableval was used
          rather than $withval (patch by Darryl Miles <dlm@g7led.demon.co.uk>).
        + modify some man-pages so no '.' or '..' falls between TH and SH
          macros, to accommodate man_db program (reported by Ian T. Zimmerman
          <itz@rahul.net>).
        + terminfo.src 10.2.1 downloaded from ESR's webpage (ESR).
        > several changes by Juergen Pfeifer:
        + add copyright notices (and rcs id's) on remaining man-pages.
        + corrected prototypes for slk_* functions, using chtype rather than
          attr_t.
        + implemented the wcolor_set() and slk_color() functions
        + the slk_attr_{set,off,on} functions need an additional void*
          parameter according to XSI.
        + fix the C++ and Ada95 binding as well as the man pages to
          reflect above enhancements.

980307
        + use 'stat()' rather than 'access()' in toe.c to check for the
          existence of $HOME/.terminfo, since it may be a file.
        + suppress configure CF_CXX_LIBRARY check if we are not using g++
          2.7.x, since this is not needed with g++ 2.8 or egcs (patch by
          Juergen Pfeifer).
        + turn on hashmap scrolling code by default, intend to remedy defects
          by 4.3 release.
        + minor corrections to terminfo.src changelog.

980302  4.2 release for upload to prep.ai.mit.edu
        + correct Florian's email address in ncurses-intro.html
        + terminfo.src 10.2.0 (ESR).

980228  pre-release
        + add linux-koi8r replace linux-koi8, which is not KOI8 (patch by
          QingLong <qinglong@Bolizm.ihep.su>).
        + minor documentation fixes (patch by Juergen Pfeifer).
        + add setlocale() call to ncurses.c (reported by Claes G. Lindblad
          <claesg@algonet.se>).
        + correct sign-extension in lib_insstr.c (reported by Sotiris
          Vassilopoulos <svas@leon.nrcps.ariadne-t.gr>)

980221  pre-release
        + regenerated some documentation overlooked in 980214 patch
          (ncurses-intro.doc, curs_outopts.3x.html)
        + minor ifdef change to C++ binding to work with gcc 2.8.0 (patch by
          Juergen Pfeifer).
        + change maintainer's mailing address to florian@gnu.org, change
          tentative mailing list address to bug-ncurses-request@gnu.org (patch
          by Florian La Roche).
        + add definition of $(REL_VERSION) to c++/Makefile.in (reported by Gran
          Hasse <gh@raditex.se>).
        + restore version numbers to Ada95 binding, accidentally deleted by
          copyright patch (patch by Juergen Pfeifer).

980214  pre-release
        + remove ncurses.lsm from MANIFEST so that it won't be used in FSF
          distributions, though it is retained in development.
        + correct scaling of milliseconds to nanoseconds in lib_napms.c (patch
          by Jeremy Buhler).
        + update mailing-list information (bug-ncurses@gnu.org).
        + update announcement for upcoming 4.2 release.
        + modify -lm test to check for 'sin()' rather than 'floor()'
        + remove spurious commas from terminfo.src descriptions.
        + change copyright notices to Free Software Foundation

980207
        + minor fixes for autoconf macros CF_ERRNO, CF_HELP_MESSAGE and
          CF_SIZECHANGE
        + modify Makefile.glibc so that $(objpfx) is defined (H.J.Lu).
        + ifdef-out true-return from _nc_mouse_inline() which depends on
          merge of QNX patch (pending 4.2 release).
        > patch to split off seldom-used modules in ncurses (J T Conklin):
          This reduces size by up to 2.6kb.
        + move functionality of _nc_usleep into napms, add configuration case
          for nanosleep().
        + moved wchgat() from lib_addch.c to lib_chgat.c
        + moved clearok(), immedok(), leaveok(), and scrollok() from
          lib_options.c to lib_clearok.c, lib_immedok.c, lib_leaveok.c and
          lib_scrollok.c.
        + moved napms() from lib_kernel.c to lib_napms.c
        + moved echo() and noecho() from lib_raw.c to lib_echo.c
        + moved nl() and nonl() from lib_raw.c to lib_nl.c

980131
        + corrected conversion in tclock.c (cf: 971018).
        + updates to Makefile.glibc and associated Linux configure script
          (patch by H.J.Lu).
        + workaround a quoting problem on SunOS with tar-copy.sh
        + correct init_pair() calls in worm.c to work when use_default_colors()
          is not available.
        + include <sys/types.h> in CF_SYS_TIME_SELECT to work with FreeBSD
          2.1.5
        + add ncv capability to FreeBSD console (cons25w), making reverse
          work with color.
        + correct sense of configure-test for sys/time.h inclusion with
          sys/select.h
        + fixes for Ada95/ada_include/Makefile.in to work with --srcdir option.
        + remove unused/obsolete test-program rules from progs/Makefile.in
          (the rules in ncurses/Makefile.in work).
        + remove shared-library loader flags from test/Makefile.in, etc.
        + simplify test/configure.in using new version of autoconf to create
          test/ncurses_cfg.h
        + suppress suffix rules in test/Makefile.in, provide explicit
          dependency to work with --srcdir option and less capable 'make'
          programs.
        > adapted from patch for QNX by Xiaodan Tang:
        + initialize %P and %g variables set/used in tparm, and also ensure
          that empty strings don't return a null result from tparam_internal
        + add QNX-specific prototype for vsscanf()
        + move initialization of SP->_keytry from init_keytry() to newterm() to
          avoid resetting it via a keyok() call by mouse_activate().
        + reorganized some functions in lib_mouse() to use case-statements.
        + remove sgr string from qnx terminfo entry since it is reported to
          turn off attributes inconsistently.

980124
        + add f/F/b/B commands to ncurses 'b' test to toggle colors, providing
          test for no_color_video.
        + adjusted emx.src to use no_color_video, now works with ncurses 'b'
          and 'k' tests.
        + implement no_color_video attribute, and as a special case, reverse
          colors when the reverse attribute cannot be combined with color.
        + check for empty string in $TERM variable (reported by Brett Michaels
          <brett@xylan.com>).
        > from reports by Fred Fish:
        + add configure-test for isascii
        + add configure-test for -lm library.
        + modify CF_BOOL_SIZE to check if C++ bool types are unsigned.
        > patches by J.J.G.Ripoll
        + add configure/makefile variables to support .exe extension on
          OS/2 EMX (requires additional autoconf patches).
        + explicitly initialize variables in lib_data.c to appease OS/2 linker
        > patches by Fred Fish <fnf@ninemoons.com>
        + misc/Makefile.in (install.data):  Avoid trying to install the CVS
          directory.
        + aclocal.m4 (install.includes):  Remove files in the include directory
          where we are going to install new ones, not the original source
          files.
        + misc/terminfo.src:  Add entry for "beterm", derived from termcap
          distributed with BeOS PR2 using captoinfo.
        + aclocal.m4: Wrap $cf_cv_type_of_bool with quotes (contains space)
        + aclocal.m4: Assume bool types are unsigned.
        + progs/infocmp.c: workaround mwcc 32k function data limit

980117
        + correct initialization of color-pair (cf: 970524) in xmas.c, which
          was using only one color-pair for all colors (reported by
          J.J.G.Ripoll).
        + add multithread options for objects build on EMX, for compatibility
          with XFree86.
        + split up an expression in MKlib_gen.sh to work around a problem on
          OS/2 EMX, with 'ash' (patch by J.J.G.Ripoll).
        + change terminfo entries xterm (xterm-xf86-v40), xterm-8bit rs1 to use
          hard reset.
        + rename terminfo entry xterm-xf86-v39t to xterm-xf86-v40
        + remove bold/underline from sun console entries since they're not
          implemented.
        + correct _tracef calls in _tracedump(), which did not separate format
          from parameters.
        + correct getopt string for tic "-o" option, and add it to man-page
          synopsis (reported by Darren Hiebert <darren@hmi.com>).
        + correct typo in panel/Makefile.in, reversed if-statement in scrolling
          optimization (Alexander V.  Lukyanov).
        + test for 'remove()', use 'unlink() if not found (patch by Philippe De
          Muyter <phdm@macqel.be>).
        > patches by Juergen Pfeifer:
        + Improve a feature of the forms driver.  For invisible fields
          (O_VISIBLE off) only the contents but not the attributes are cleared.
          We now clear both.  (Reported by Javier Kohan
          <jkohan@adan.fceia.unr.edu.ar>)
        + The man page form_field_opts.3x makes now clear, that invisible
          fields are also always inactive.
        + adjust ifdef's to compile the C++ binding with the just released
          gcc-2.8.0 c++ and the corresponding new C++ libraries.

980110
        + correct "?" command in ncurses.c; it was performing non-screen writes
          while the program was in screen mode.  (It "worked" in 1.9.9e because
          that version sets OPOST and OCRNL incorrectly).
        + return error from functions in lib_kernel, lib_raw and lib_ti if
          cur_term is null, or if underlying I/O fails.
        + amend change to tputs() so that it does not return an error if
          cur_term is null, since some applications depend on being able to use
          tputs without initializing the terminal (reported by Christian J.
          Robinson <infynity@cyberhighway.net>).

980103
        + add a copy of emx.src from J.J.G.Ripoll's OS/2 EMX version of ncurses
          1.9.9e, together with fixes/additions for the "ansi" terminal type.
        + add tic check for save/restore cursor if change_scroll_region is
          defined (reference: O'Reilly book).
        + modify read_termcap.c to handle EMX-style pathnames (reported by
          J.J.G.Ripoll).
        + modify lib_raw.c to use EMX's setmode (patch from J.J.G.Ripoll).
          Ripoll says EMX's curses does this.
        + modify _nc_tic_expand() to generate \0 rather than \200.
        + move/revise 'expand()' from dump_entry.c to ncurses library as
          _nc_tic_expand(), for use by tack.
        + decode \a as \007 for terminfo, as per XSI.
        + correct translation of terminfo "^@", to \200, like \0.
        + modify next_char() to treat <cr><lf> the same as <newline>, for
          cross-platform compatibility.
        + use new version of autoconf (971230) to work around limited
          environment on CLIX, due to the way autoconf builds --help message.
        > patch by Juergen Pfeifer:
        + check that the Ada95 binding runs against the correct version of
          ncurses.
        + insert constants about the library version into the main spec-file of
          the Ada95 binding.

971227
        + modify open/fopen calls to use binary mode, needed for EMX.
        + modify configure script to work with autoconf 2.10 mods for OS/2
          EMX (from J.J.G.Ripoll).
        + generated ncurses_cfg.h with patch (971222) to autoconf 2.12 which
          bypasses limited sed buffer length.
        > several changes from Juan Jose Garcia Ripoll <worm@arrakis.es>
          (J.J.G.Ripoll) to support OS/2 EMX:
        + add a _scrolling flag to SP, to set when we encounter a terminal
          that simply cannot scroll.
        + corrected logic in _nc_add_to_try(), by ensuring that strings with
          embedded \200 characters are matched.
        + don't assume the host has 'link()' function, for linking terminfo
          entries.

971220
        + if there's no ioctl's to support sigwinch handler, disable it.
        + add configure option --disable-ext-funcs to remove the extended
          functions from the build.
        + add configure option --with-termlib to generate the terminfo
          functions as a separate library.
        + add 'sources' rule to facilitate cross-compiling.
        + review/fix order of mostlyclean/clean/distclean rules.
        + modify install-rule for headers to first remove old header, in
          case there was a symbolic link that confuses the install script.
        + corrected substitution for NCURSES_CONST in term.h (cf: 971108)
        + add null pointer checks in wnoutrefresh(), overlap() (patch by
          Xiaodan Tang <xtang@qnx.com>)
        + correct tputs(), which could dereference a null cur_term if invoked
          before terminal is initialized (patch by Christopher Seawood
          <cls@seawood.org>)
        > patch by Juergen Pfeifer:
        + makes better use of "pragma Inline" in the Ada95 binding
        + resynchronizes the generated html manpages

971213
        + additional fixes for man-pages section-references
        + add (for debugging) a check for ich/ich1 conflict with smir/rmir
          to tic, etc.
        + remove hpa/vpa from rxvt terminal description because they are not
          implemented correctly, added sgr0.
        + change ncurses 's' to use raw mode, so ^Q works (reported by Rudolf
          Leitgeb <leitgeb@leland.stanford.edu>)

971206
        + modify protection when installing libraries to (normally) not
          executable.  HP-UX shared libraries are an exception.
        + add configure check for 'tack'.
        + implement script for renaming section-references in man-page install,
          for Debian configuration.
        + add validity-check for SP in trace code in baudrate() (reported by
          Daniel Weaver).
        > patch by Alexander V. Lukyanov (fixes to match sol25 curses)
        + modify 'overlay()' so that copy applies target window background to
          characters.
        + correct 'mvwin()' so that it does not clear the previous locations.
        + correct lib_acs.c so that 8-bit character is not sign expanded in
          case of wide characters in chtype.
        + correct control-char test in lib_addch.c for use with wide chars
        + use attribute in the chtype when adding a control character in
          lib_addch.c control char was added with current attribute

971129
        + save/restore errno in _tracef() function
        + change treatment of initialize_color to use a range of 0..1000
          (recommended by Daniel Weaver).
        + set umask in mkinstalldirs, fixing problems reported by users who
          have set root's umask to 077.
        + correct bug in tic that caused capabilities to be reprinted at the
          end of output when they had embedded comments.
        + rewrote wredrawln to correspond to XSI, and split-out since it is
          not often used (from report by Alexander V. Lukyanov, 970825)
        + rewrote Dan Nelson's change to make it portable, as well as to
          correct logic for handling backslashes.
        + add code to _nc_tgetent() to make it work more like a real tgetent().
          It removes all empty fields, and removes all but the first in a group
          of duplicate caps.  The code was pulled from the BSD libtermcap code
          in termcap.c (patch by Dan Nelson <dnelson@emsphone.com>
        + don't include --enable-widec in the --with-develop configure option,
          since it is not binary-compatible with 4.1 (noted by Alexander V.
          Lukyanov)
        > patch by Juergen Pfeifer:
        + further improvements of the usage of elaboration pragmas in the Ada95
          binding
        + enhanced Ada95 sample to use the user_data mechanism for panels.
        + a fix for the configuration script to make gnat-3.10 the required
          version.
        + resync of the html version of the manpages

971122
        > fixes/updates for terminfo.src:
        + add vt220-js, pilot, rbcomm, datapoint entries from esr's 27-jun-97
          version.
        + add hds200 description (Walter Skorski)
        + add EMX 0.9b descriptions
        + correct rmso/smso capabilities in wy30-mc and wy50-mc (Daniel Weaver)
        + rename xhpterm back to hpterm.
        > patch by Juergen Pfeifer:
        + Improves the usage of elaboration pragmas for the Ada95 binding.
        + Adds a translation of the test/rain.c into Ada95 to the samples.
          This has been contributed to the project by Laurent Pautet
          (pautet@gnat.com)

971115
        + increase MAX_NAME_SIZE to 512 to handle extremely long alias list
          in HP-UX terminfo.
        + correction & simplification of delay computation in tputs, based on
          comments from Daniel Weaver.
        + replace test for SCO with more precise header tests.
        + add configure test for unsigned literals, use in NCURSES_BITS macro.
        + comment-out the -PIC, etc., flags from c++, progs and test makefiles
          since they probably are not needed, and are less efficient (noted by
          Juergen Fluk)
        + add -L$(libdir) to loader options, after -L../lib so that loaders
          that record this information will tend to do the right thing if
          the programs are moved around after installing them (suggested by
          Juergen Fluk).
        + add -R option to loader options for programs for Solaris if the
          --enable-rpath option is specified for the libraries.

971112
        + correct installed filename for shared libraries on *BSD (reported by
          Juergen Fluk).

971108
        + cleanup logic for deciding when tputs() should call delay_output(),
          based on comments from Daniel Weaver.
        + modified tputs() to avoid use of float.
        + correct use of trailpad in tputs(), which used the wrong variable
          in call to delay_output().
        + correct inverted expression for null-count in delay_output()
          (analysis by Daniel Weaver).
        + apply --enable-rpath option to Solaris (requested by Larry Virden).
        + correct substitution of EXTRA_CFLAGS for gcc 2.6.3
        + correct check for error-return by _nc_tgetent(), which returns 0
          for success.
        + add configure test for BSD 4.4 cgetent() function, modify
          read_termcap.c to use the host's version of that if found, using the
          terminal database on FreeBSD (reported by Peter Wemm).
        + add u8, u9 strings to sun-il description for Daniel Weaver.
        + use NCURSES_CONST in panel's user-pointer.
        + modify edit_cfg.sh and MKterm.h.awk.in to substitute NCURSES_CONST
          so that will work on NeXT.
        + use _nc_set_screen() rather than assignments to SP to fix port to
          NeXT (reported by Francisco A. Tomei Torres).

971101
        + force mandatory padding in bell and flash_screen, as specified in
          XSI.
        + don't allow padding_baud_rate to override mandatory delays (reported
          by Daniel Weaver).
        + modify delay_output() to use _nc_timed_wait() if no baudrate has been
          defined, or if the cur_term pointer is not initialized.  XSI treats
          this as unspecified.  (requested by Daniel Weaver).
        + change getcap-cache ifdef's to eliminate unnecessary chdir/mkdir
          when that feature is not configured.
        + remove _nc_err_abort() calls when write_entry.c finds a directory but
          cannot write to it, e.g., when translating part/all of /etc/termcap
          (reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>).
          (this dates back to 951102 in 1.9.7a).
        + minor ifdef fixes to compile with atac and glibc 2.0.5c
        + add check for -lgen when configuring regexpr.h
        + modify Solaris shared-library option "-d y" to "-dy" to workaround
          incompatibility of gcc 2.7.2 vs vendor's tools.

971026
        + correct ifdef's for struct winsize vs struct ttysize in lib_setup.c
          to compile on SCO.
        + remove dangling backslash in panel/Makefile.in
        + modify MKkeyname.awk to work with SCO's nawk, which dumps core in the
          length() function.
        + correct length of allocation in _nc_add_to_try(), to allow for
          trailing null.
        + correct logic in _nc_remove_key(), which was discarding too many
          nodes (patch by Alexander V. Lukyanov)

971025
        + add definition for $(REL_VERSION) to test/Makefile.in, so *BSD
          shared libraries link properly (see 970524).
        + modify Linux shared-library generation to include library
          dependencies (e.g., -lncurses and -lgpm) in the forms, menu and
          panel libraries (suggested by Juergen Pfeifer).
        + modify configure script to use config.guess and config.sub rather
          than uname, which is unreliable on some systems.
        + updated Makefile.glibc, test-built with glibc 2.0.5c
        + modify keyname() to return values consistent with SVr4 curses (patch
          by Juergen Fluk).
        > changes requested by Daniel Weaver:
        + modify delay_output() so that it uses the same output function as
          tputs() if called from that function.
        + move _baudrate from SCREEN to TERMINAL so that low-level use of
          tputs works when SP is not set.
        > patch by Juergen Pfeifer:
        + factor lib_menu and lib_form into smaller modules
        + clean up the interface between panel and SCREEN
        + minor changes to the Ada95 mouse support implementation
        + minor bugfix in C++ binding to ripoff windows
        + fix a few Ada95 html documentation pages

971018
        + split-out lib_ungetch.c, make runtime link to resizeterm() to
          decouple those modules from lib_restart.c
        + add xterm-xf86-v39t description to terminfo.src
        + reset SP->_endwin in lib_tstp.c cleanup() function after calling
          endwin() to avoid unnecessary repainting if the application has
          established an atexit function, etc.  Encountered this problem in
          the c++ demo, whose destructors repaint the screen.
        + combine _nc_get_screensize() and resizeterm() calls as new function
          _nc_update_screensize().
        + minor fixes to allow compile with g++ (suggested by Nelson H. F.
          Beebe).
        + implement install-rules for Ada95 makefiles.
        + use screen_lines or MAXLINES as needed where LINES was coded,
          as well as screen_columns for COLS, in the ncurses library.
        > patch by Alexander V. Lukyanov:
        + modify logic for ripped-off lines to handle several SCREENs.
        > patch by Juergen Pfeifer:
        + factors lib_slk.c into some smaller modules
        + factors panel.c into some smaller modules
        + puts the static information about the current panel stack into the
          SCREEN structure to allow different panel stacks on different
          screens.
        + preliminary fix for an error adjusting LINES to account for
          ripped-off lines.

971011
        + move _nc_max_click_interval and other mouse interface items to SCREEN
          struct so that they are associated with a single terminal, and also
          save memory when the application does not need a mouse (roughly 3k vs
          0.5k on Linux).
        + modify mouseinterval() so that a negative parameter queries the
          click-interval without modifying it.
        + modify ncurses 'i' test to work with ncurses' apparent extension from
          SVr4, i.e., allows nocbreak+noecho (analysis by Alexander V.
          Lukyanov).
        + add configure options --with-ada-includes and --with-ada-objects,
          to drive Ada95 binding install (not yet implemented).
        + install C++ binding as -lncurses++ and associated headers with the
          other ncurses headers.
        + fix header uninstall if configure --srcdir is used.
        > minor interface changes to support 'tack' program -TD
          (request by Daniel Weaver <danw@znyx.com>).
        + export functions _nc_trans_string() and _nc_msec_cost().
        + add variable _nc_nulls_sent, to record the number of padding
          characters output in delay_output().
        + move tests for generic_type and hard_copy terminals in setupterm()
          to the end of that function so that the library will still be
          initialized, though not generally useful for curses programs.
        > patches by Alexander V. Lukyanov:
        + modify ClrBottom() to avoid using clr_eos if there is only one line
          to erase.
        + typo in configure --help.
        > patch by J T Conklin (with minor resync against Juergen's changes)
        + split-out lib_flash.c from lib_beep.c
        + split-out lib_hline.c and lib_vline.c from lib_box.c
        + split-out lib_wattron.c, lib_wattroff.c from lib_addch.c

971005
        > patch by Juergen Pfeifer:
        + correct source/target of c++/edit_cfg.sh

971004
        + add color, mouse support to kterm terminfo entry.
        + modify lib_mouse.c to recognize rxvt, kterm, color_xterm also as
          providing "xterm"-style mouse.
        + updated rxvt's terminfo description to correspond to 2.21b, with
          fixes for the acsc (the box1 capability is incorrect, ech1 does not
          work).
        + fix logic in parse_entry.c that discarded acsc when 'synthesizing'
          an entry from equivalents in XENIX or AIX.  This lets ncurses handle
          the distribution copy of rxvt's terminfo.
        + modify acsc capability for linux and linux-koi8 terminfo descriptions
          (from Pavel Roskin <pavel@absolute.spb.su>).
        + corrected definition in curses.h for ACS_LANTERN, which was 'I'
          rather than 'i' (see 970802).
        + updated terminfo.src with reformatted acsc entries, and repaired the
          trashed entries with spurious '\' characters that this exposed.
        + add logic to dump_entry.c to reformat acsc entries into canonical
          form (sorted, unique mapping).
        + add configure script to generate c++/etip.h
        + add configure --with-develop option, to enable by default most of the
          experimental options (requested by Alexander V. Lukyanov).
        + rename 'deinstall' to 'uninstall', following GNU convention
          (suggested by Alexander V. Lukyanov).
        > patches by Alexander V. Lukyanov:
        + modify tactics 2 and 5 in onscreen_mvcur(), to allow them on the last
          line of the screen, since carriage return will not cause a newline.
        + remove clause from PutCharLR() that would try to use
          eat_newline_glitch since that apparently does not work on some
          terminals (e.g., M$ telnet).
        + correct a limit check in scroll_csr_backward()
        > patches by Juergen Pfeifer:
        + adds dummy implementations of methods above() and below() to the
          NCursesPanel class.
        + fixes missing returncode in NCursesWindow::ripoffline()
        + fixes missing returncode in TestApplication::run() in demo.cc
        + We should at least give a comment in etip.h why it is currently a
          problem to install the C++ binding somewhere
        + makes the WINDOW* argument of wenclose() a const.
        + modifies several of the routines in lib_adabind.c to use a const
          WINDOW* argument.

970927
        + add 'deinstall' rules.
        + use explicit assignments in configure --without-progs option to
          work around autoconf bug which doesn't always set $withval.
        + check for ldconfig, don't try to run it if not found.
        + implement simple/unoptimized case in lib_doupdate.c to handle
          display with magic cookie glitch, tested with ncurses.c program.
        + correct missing _tracef in getmouse(), to balance the returnCode
          macro.
        + simplify show_attr() in ncurses.c using termattrs().
        > patches by Juergen Pfeifer:
        + provides missing inlines for mvw[hv]line in cursesw.h of the C++
          binding
        + fixes a typo in a comment of frm_driver.c
        + Enhances Ada95 Makefiles to fulfill the requirement of GNAT-3.10 that
          generics should be compiled.  Proper fixes to the configuration
          scripts are also provided.

970920
        + several modifications to the configure script (requested by Ward
          Horner):
          + add configure options --without-progs, to suppress the build of the
            utility programs, e.g., for cross-compiling.
          + add $(HOSTCCFLAGS) and $(HOSTLDFLAGS) symbols to ncurses
            Makefile.in, to simplify setup for cross compiling.
          + add logic in configure script to recognize "--target=vxworks", and
            generate load/install actions for VxWorks objects.
        + move typedef for sigaction_t into SigAction.h to work around problem
          generating lint library.
        + modify fty_regex.c to reflect renaming of ifdef's for regular
          expressions.
        + simplify ifdef in lib_setup.c for TIOCGWINSZ since that symbol may
          reside in <sys/ioctl.h>.
        + merge testcurs.c with version from PDCurses 2.3, clarifying some of
          the more obscure tests, which rely upon color.
        + use macros getbegyx() and getmaxyx() in newdemo.c and testcurs.c
        + modify ncurses.c to use getbegyx() and getmaxyx() macros to cover up
          implementation difference wrt SVr4 curses, allow 's' test to work.
        + add missing endwin() to testscanw.c program (reported by Fausto
          Saporito <fausap@itb.it>).
        + fixes/updates for Makefile.glibc and related files under sysdeps
          (patch by H.J.Lu).
        > patches by Juergen Pfeifer:
        + add checks for null pointers, especially WINDOW's throughout the
          ncurses library.
        + solve a problem with wrong calculation of panel overlapping (reported
          by Ward Horner):
          + make sure that a panel's window isn't a pad.
          + do more error checking in module lib_touch.c
        + missing files for Ada95 binding from the last patch
        + synch. of generated html pages (RCS-Id's were wrong in html files)
        + support for Key_Resize in Ada binding
        + changed documentation style in ./c++/cursesm.h
        > patches by Alexander V. Lukyanov:
        + undo attempt to do recursive inlining for PutChar(), noting that it
          did not improve timing measurably, but inflated the size of
          lib_doupdate.o

970913
        + modify rain.c to use color.
        + correct scroll_csr_backward() to match scroll_csr_forward().
        + minor adjustment to llib-lncurses, to work with Solaris 2.5.1
        + minor fixes to sysdeps/unix/sysv/linux/configure to reflect renaming
          of configure cache variables in 970906.
        + correct logic involving changes to O_VISIBLE option in
          Synchronize_Options function in frm_driver.c (Tony Hoffmann
          <Tony.Hoffmann@hia.nrc.ca>)
        + add $(HOSTCC) symbol to ncurses Makefile.in, to simplify setup for
          cross compiling (suggested by Chris Johns).
        + modify ifdef in lib_setup.c to only include <sys/ioctl.h> if we can
          use it to support screen-size calculation (reported by Chris Johns).
        + #undef unctrl to avoid symbol conflict in port to RTEMS (reported by
          Chris Johns <cjohns@plessey.com.au>)
        > patches by Juergen Pfeifer:
        + simplified, made minor corrections to Ada95 binding to form
          fieldtype.
        + The C++ binding has been enhanced:
          + Improve NCursesWindow class:  added additional methods to cover
            more ncurses functionality.  Make refresh() and noutrefresh()
            virtual members to allow different implementation in the
            NCursesPanel class.
          + CAUTION:  changed order of parameters in vline() and hline() of
            NCursesWindow class.
          + Make refresh() in NCursesPanel non-static, it is now a
            reimplementation of refresh() in the base class.  Added
            noutrefresh() to NCursesPanel.
          + Added NCursesForm and related classes to support libform
            functionality.
          + Moved most of configuration related stuff from cursesw.h to etip.h
          + Added NCursesApplication class to support easy configuration of
            menu and forms related attributes as well as ripped of title lines
            and Soft-Label-Keys for an application.
          + Support of Auto-Cleanup for a menu's fieldlist.
          + Change of return type for current_item() and operator[] for menus.
          + Enhanced demo.
        + Fixed a bug in form/fld_def.c:  take into account that copyarg and
          freearg for a fieldtype may be NULL, makearg must not be NULL
        + Fixed a bug in form/fld_type.c:  in set_fieldtype_arg() makearg must
          not be NULL, copyarg and freearg may be NULL.
        + Fixed a bug in form/frm_def.c:  Allow Disconnect_Fields() if it is
          already disconnected.
        + Enhance form/frm_driver.c:  Allow growth of dynamic fields also on
          navigation requests.
        + Fixed a bug in form/fty_enum.c:  wrong position of postincrement in
          case-insensitiva comparison routine.
        + Enhanced form/lib_adabind.c with function _nc_get_field() to get a
          forms field by index.
        + Enhanced menu/m_adabind.c with function _nc_get_item() to get a menus
          item by index.
        + Fixed in curses.h.in:  make chtype argument for pechochar() constant.
          Mark wbkgdset() as implemented, remove wbkgdset macro, because it was
          broken (didn't handle colors correctly).
        + Enhanced lib_mouse.c: added _nc_has_mouse() function
        + Added _nc_has_mouse() prototype to curses.priv.h
        + Modified lib_bkgd.c:  hopefully correct implementation of wbkgdset();
          streamlined implementation of wbkgd()
        + Modified lib_mvwin.c:  Disable move of a pad.  Implement (costly)
          move of subwindows.  Fixed update behavior of movements of regular
          windows.
        + Fixed lib_pad.c:  make chtype argument of pechochar() const.
        + Fixed lib_window.c:  dupwin() is not(!) in every bit a really clone
          of the original.  Subwindows become regular windows by doing a
          dupwin().
        + Improved manpage form_fieldtype.3x
        > patches by Alexander V. Lukyanov:
        + simplify the PutChar() handling of exit_am_mode, because we already
          know that auto_right_margin is true.
        + add a check in PutChar() for ability to insert to the case of
          shifting character to LR corner.
        + in terminal initialization by _nc_screen_resume(), make sure that
          terminal right margin mode is known.
        + move logic that invokes touchline(), or does the equivalent, into
          _nc_scroll_window().
        + modify scrolling logic use of insert/delete line capability, assuming
          that they affect the screen contents only within the current
          scrolling region.
        + modify rain.c to demonstrate SIGWINCH handler.
        + remove logic from getch() that would return an ERR if the application
          called getch() when the cursor was at the lower-right corner of the
          physical screen, and the terminal does not have insert-character
          ability.
        + change view.c so that it breaks out of getch() loop if a KEY_RESIZE
          is read, and modify logic in getch() so this fix will yield the
          desired behavior, i.e., the screen is repainted automatically when
          the terminal window is resized.

970906
        + add configure option --enable-sigwinch
        + modify view.c to test KEY_RESIZE logic, with "-r" option.
        + modify testcurs.c to eliminate misleading display wrt cursor type
          by testing if the terminal supports cnorm, civis, cvvis.
        + several fixes for m68k/NeXT 4.0, to bring cur_term, _nc_curr_line and
          _nc_curr_col variables into linked programs:  move these variables,
          making new modules lib_cur_term and trace_buf (reported by Francisco
          Alberto Tomei Torres <fatomei@sandburg.unm.edu>).
        > patches by Alexander V. Lukyanov:
        + add pseudo-functionkey KEY_RESIZE which is returned by getch() when
          the SIGWINCH handler has been called since the last call to
          doupdate().
        + modify lib_twait.c to hide EINTR only if HIDE_EINTR is defined.
        + add SIGWINCH handler to ncurses library which is used if there is no
          application SIGWINCH handler in effect when the screen is
          initialized.
        + make linked list of all SCREEN structures.
        + move curses.h include before definition of SCREEN to use types in
          that structure.
        + correction to ensure that wgetstr uses only a newline to force a
          scroll (970831).

970831
        + add experimental configure option --enable-safe-sprintf; the normal
          mode now allocates a buffer as large as the screen for the
          lib_printw.c functions.
        + modify wgetch to refresh screen when reading ungetch'd characters,
          since the application may require this - SVr4 does this.
        + refine treatment of newline in wgetstr to echo only when this would
          force the screen to scroll.

970830
        + remove override in wgetstr() that forces keypad(), since SVr4 does
          not do this.
        + correct y-reference for erasure in wgetstr() when a wrap forces a
          scroll.
        + correct x-position in waddch() after a wrap forces a scroll.
        + echo newline in wgetstr(), making testscanw.c scroll properly when
          scanw is done.
        + modify vwscanw() to avoid potential buffer overflow.
        + rewrote lib_printw.c to eliminate fixed-buffer limits.
        > patches by Alexander V. Lukyanov:
        + correct an error in handling cooked mode in wgetch(); processing
          was in the wrong order.
        + simplified logic in wgetch() that handles backspace, etc., by using
          wechochar().
        + correct wechochar() so that it interprets the output character as
          in waddch().
        + modify pechochar() to use prefresh() rather than doupdate(), since
          the latter does not guarantee immediate refresh of the pad.
        + modify pechochar() so that if called with a non-pad WINDOW, will
          invoke wechochar() instead.
        + modify fifo indices to allow fifo to be longer than 127 bytes.

970823
        + add xterm-8bit to terminfo.src
        + moved logic for SP->_fifohold inside check_pending() to make it
          work properly when we add calls to that function.
        + ensure that bool functions return only TRUE or FALSE, and TRUE/FALSE
          are assigned to bool values (patch by H.J.Lu).
        > patches by Alexander V. Lukyanov:
        + several fixes to getch:
          1.  Separate cooked and raw keys in fifo
          2.  Fix the case of ungetch'ed KEY_MOUSE
          3.  wrap the code for hiding EINTR with ifdef HIDE_EINTR
          4.  correctly handle input errors (i.e., EINTR) without loss of raw
              keys
          5.  recognize ESC KEY_LEFT and similar
          6.  correctly handle the case of reception of KEY_MOUSE from gpm
        + correct off-by-one indexing error in _nc_mouse_parse(), that caused
          single mouse events (press/release) to be ignored in favor of
          composed events (click).  Improves on a fix from integrating gpm
          support in 961229.
        + add another call to check_pending, before scrolling, for
          line-breakout optimization
        + improve hashmap.c by
          1.  fixed loop condition in grow_hunks()
          2.  not marking lines with offset 0
          3.  fixed condition of 'too far' criteria, thus one-line hunks are
          ignored and two lines interchanged won't pass.
        + rewrote/simplified _nc_scroll_optimize() by separating into two
          passes, forward/backward, looking for chunks moving only in the given
          direction.
        + move logic that emits sgr0 when initializing the screen to
          _nc_screen_init(), now invoked from newterm.
        + move cursor-movement cleanup from endwin() into _nc_mvcur_wrap()
          function and screen cleanup (i.e., color) into _nc_screen_wrap()
          function.
        + add new functions _nc_screen_init(), _nc_screen_resume() and
          _nc_screen_wrap().
        + rename _nc_mvcur_scrolln() to _nc_scrolln().
        + add a copy of acs_map[] to the SCREEN structure, where it can be
          stored/retrieved via set_term().
        + move variables _nc_idcok, _nc_idlok, _nc_windows into the SCREEN
          structure.

970816
        + implement experimental _nc_perform_scroll().
        + modify newterm (actually _nc_setupscreen()) to emit an sgr0 when
          initializing the screen, as does SVr4 (reported by Alexander V.
          Lukyanov).
        + added test_progs rule to ncurses/Makefile.
        + modify test/configure.in to check if initscr is already in $LIBS
          before looking for (n)curses library.
        + correct version-number in configure script for OSF1 shared-library
          options (patch by Tim Mooney).
        + add -DNDEBUG to CPPFLAGS for --enable-assertions (as Juergen
          originally patched) since the c++ demo files do not necessarily
          include ncurses_cfg.h
        + supply default value for --enable-assertions option in configure
          script (reported by Kriang Lerdsuwanakij <lerdsuwa@scf-fs.usc.edu>).
        > patches by Alexander V. Lukyanov:
        + correct/simplify logic of werase(), wclrtoeol() and wclrbot().  See
          example firstlast.c
        + optimize waddch_literal() and waddch_nosync() by factoring out
          common subexpressions.
        + correct sense of NDEBUG ifdef for CHECK_POSITION macro.
        + corrections to render_char(), to make handling of colored blanks
          match SVr4 curses, as well as to correct a bug that xor'd space
          against the background character.
        + replaced hash function with a faster one (timed it)
        + rewrote the hashmap algorithm to be one-pass, this avoids multiple
          cost_effective() calls on the same lines.
        + modified cost_effective() so it is now slightly more precise.
        > patches for glibc integration (H.J.Lu):
        + add modules define_key, keyok, name_match, tries
        + add makefile rules for some of the unit tests in ncurses (mvcur,
          captoinfo, hardscroll, hashmap).
        + update Linux configure-script for wide-character definitions.

970809
        + modify _tracebits() to show the character size (e.g., CS8).
        + modify tparm() to emit '\200' where the generated string would have a
          null (reported by From:  Ian Dall <Ian.Dall@dsto.defence.gov.au> for
          terminal type ncr7900).
        + modify install process so that ldconfig is not invoked if the
          package is built with an install-prefix.
        + correct test program for chtype size (reported by Tim Mooney).
        + add configure option --disable-scroll-hints, using this to ifdef the
          logic that computes indices for _nc_scroll_optimize().
        + add module ncurses/softscroll.c, to perform single-stage computation
          of scroll indices used in _nc_scroll_optimize().  This is faster than
          the existing scrolling algorithm, but tends to make too-small hunks.
        + eliminate fixed buffer size in _nc_linedump().
        + minor fixes to lib_doupdate.c to add tradeoff between clr_eol (el)
          and clr_bol (el1), refine logic in ClrUpdate() and ClrBottom() (patch
          by Alexander V. Lukyanov).
        + add test/testaddch.c, from a pending patch by Alexander V. Lukyanov.
        + correct processing of "configure --enable-assertions" option (patch
          by Juergen Pfeifer).

970802
        + add '-s' (single-step) option too test/hashtest.c, correct an error
          in loop limit for '-f' (footer option), toggle scrollok() when
          writing footer to avoid wrap at lower-right corner.
        + correct behavior of clrtoeol() immediately after wrapping cursor,
          which was not clearing the line at the cursor position (reported by
          Liviu Daia <daia@stoilow.imar.ro>).
        + corrected mapping for ACS_LANTERN, which was 'I' rather than 'i'
          (reported by Klaus Weide <kweide@tezcat.com>).
        + many corrections to make progs/capconvert work, as well as make it
          reasonably portable and integrated with ncurses 4.1 (reported by Dave
          Furstenau <df@ravine.binary.net>).

970726
        + add flag SP->_fifohold, corresponding logic to modify the behavior of
          the line breakout logic so that if the application does not read
          input, refreshes will not be stopped, but only slowed.
        + generate slk_attr_off(), slk_attr_on(), slk_attr_set(), vid_attr(),
          ifdef'd for wide-character support, since ncurses' WA_xxx attribute
          masks are identical with the A_xxx masks.
        + modify MKlib_gen.sh to generate ifdef'd functions to support optional
          configuration of wide-characters.
        + modify tset to behave more like SVr4's tset, which does not modify
          the settings of intr, quit or erase unless they are given as command
          options (reported by Nelson H. F. Beebe <beebe@math.utah.edu>).
        + modify tset to look in /etc/ttys or /etc/ttytype if the configuration
          does not have getttynam().
        + extend baudrate table in tset.c to match baudrate() function.
        + add table entries for B230400 and B460800 to baudrate() function.
        + improve breakout logic by allowing it before the first line updated,
          which is what SVr4 curses does (patch by Alexander V. Lukyanov).
        + correct initialization of vcost in relative_move(), for cursor-down
          case (patch by Alexander V. Lukyanov).
        > nits gleaned from Debian distribution of 1.9.9g-3:
        + install symbolic link for intotocap.
        + reference libc directly when making shared libraries.
        + correct renaming of curs_scr_dmp.3x in man_db.renames.
        + guard tgetflag() and other termcap functions against null cur_term
          pointer.

970719
        + corrected initial state of software echo (error in 970405, reported
          by Alexander V. Lukyanov).
        + reviewed/added messages to configure script, so that all non-test
          options should be accompanied by a message.
        + add configure check for long filenames, using this to determine if
          it is safe to allow long aliases for terminal descriptions as does
          SVr4.
        + add configure options for widec (wide character), hashmap (both
          experimental).
        > patch by Alexander V. Lukyanov:
        + hashmap.c - improved by heuristic, so that scroll test works much
          better when csr is not available.
        + hardscroll.c - patched so that it continues to scroll other chunks
          after failure to scroll one.
        + lib_doupdate.c - _nc_mvcur_scrolln extended to handle more cases; csr
          is avoided as it is relative costly.  Fixed wrong coordinates in one
          case and wrong string in TRACE.
        > patch by Juergen Pfeifer:
        + modify C++ binding to compile on AIX 4.x with the IBM C-SET++
          compiler.

970712
        + remove alternate character set from kterm terminfo entry; it uses the
          shift-out control for a purpose incompatible with curses, i.e., font
          switching.
        + disentangle 'xterm' terminfo entry from some derived entries that
          should be based on xterm-r6 instead.
        + add cbt to xterm-xf86-xv32 terminfo entry; I added the emulation for
          XFree86 3.1.2F, but overlooked its use in terminfo then - T.Dickey.
        + correct logic in lib_mvcur.c that uses back_tab.

970706
        + correct change from 970628 to ClrUpdate() in lib_doupdate.c so that
          contents of curscr are saved in newscr before clearing the screen.
          This is needed to make repainting work with the present logic of
          TransformLine().
        + use napms() rather than sleep() in tset.c to avoid interrupting I/O.

970705
        + add limit checks to _nc_read_file_entry() to guard against overflow
          of buffer when reading incompatible terminfo format, e.g, from OSF/1.
        + correct some loop-variable errors in xmc support in lib_doupdate.c
        + modify ncurses 'b' test to add gaps, specified by user, to allow
          investigation of interaction with xmc (magic cookie) code.
        + correct typo in 970524 mods to xmas.c, had omitted empty parameter
          list from has_colors(), which gcc ignores, but SVr4 does not
          (reported by Larry Virden).
        + correct rmso capability in wy50-mc description.
        + add configure option "--enable-hard-tabs", renamed TABS_OK ifdef to
          USE_HARD_TABS.
        > patch by Juergen Pfeifer:
        + Add bindings for keyok() and define_key() to the Ada95 packages.
        + Improve man pages menu_post.3x and menu_format.3x
        + Fix the HTML pages in the Ada95/html directory to reflect the above
          changes.

970628
        + modify change from 970101 to ClrUpdate() in lib_doupdate.c so that
          pending changes to both curscr and newscr are flushed properly.
          This fixes a case where the first scrolling operation in nvi would
          cause the screen to be cleared unnecessarily and repainted before
          doing the indexing, i.e., by repeatedly pressing 'j' (reported by
          Juergen Pfeifer).
        + correct error in trans_string() which added embedded newlines in a
          terminfo description to the stored strings.
        + remove spurious newlines from sgr in wyse50 (and several other)
          terminfo descriptions.
        + add configure option for experimental xmc (magic cookie) code,
          "--enable-xmc-glitch".  When disabled (the default), attributes that
          would store a magic cookie are suppressed in vidputs().  The magic
          cookie code is far from workable at this stage; the configuration
          option is a stopgap.
        + move _nc_initscr() from lib_initscr.c to lib_newterm.c
        + correct path for invoking make_keys (a missing "./").

970621
        + correct sign-extension problem with "infocmp -e", which corrupted
          acsc values computed for linux fallback data.
        + correct dependency on ncurses/names.c (a missing "./").
        + modify configure script to use '&&' even for cd'ing to existing
          directories to work around broken shell interpreters.
        + correct a loop-limit in _nc_hash_map() (patch by Alexander V.
          Lukyanov).

970615
        + restore logic in _nc_scroll_optimize() which marks as touched the
          lines in curscr that are shifted.
        + add new utility 'make_keys' to compute keys.tries as a table rather
          than a series of function calls.
        + correct include-dependency for tic.h used by name_match
        + removed buffer-allocation for name and description from m_item_new.c,
          since this might result in incompatibilities with SVr4.  Also fixed
          the corresponding Ada95 binding module (patch by Juergen Pfeifer,
          report by Avery Pennarun <apenwarr@foxnet.net>)
        + removed the mechanism to timestamp the generated Ada95 sources.  This
          resulted always in generating patches for the HTML doc, even when
          nothing really changed (patch by Juergen Pfeifer).
        + improve man page mitem_new.3x (patch by Juergen Pfeifer).

970614
        + remove ech capability from rxvt description because it does not work.
        + add missing case logic for infocmp -I option (reported by Lorenzo M.
          Catucci <lorenzo@argon.roma2.infn.it>)
        + correct old bug in pnoutrefresh() unmasked by fix in 970531; this
          caused glitches in the ncurses 'p' test since the area outside the
          pad was not compared when setting up indices for _nc_scroll_optimize.
        + rewrote tracebits() to workaround misdefinition of TOSTOP on Ultrix
          4.4, as well as to eliminate fixed-size buffer (reported by Chris
          Tanner <tannerc@aecl.ca>)
        + correct prototype for termattrs() as per XPG4 version 2.
        + add placeholder prototypes for color_set(), erasewchar(),
          term_attrs(), wcolor_set() as per XPG4 version 2.
        + correct attribution for progs/progs.priv.h and lib_twait.c
        + improve line-breakout logic by checking based on changed lines rather
          than total lines (patch by Alexander V. Lukyanov).
        + correct loop limits for table-lookup of enumerated value in form
          (patch by Juergen Pfeifer).
        + improve threshold computation for determining when to call ClrToEOL
          (patch by Alexander V. Lukyanov).

970531
        + add configure option --disable-database to force the library to
          use only the fallback data.
        + add configure option --with-fallbacks, to specify list of fallback
          terminal descriptions.
        + add a symbolic link for ncurses.h during install; too many programs
          still assume there's an ncurses.h
        + add new terminfo.src entry for xterm-xf86-v33.
        + restore terminfo.src entry for emu to using setf/setb, since it is
          not, after all, generating ANSI sequences.  Corrected missing comma
          that caused setf/setb entries to merge.
        + modify mousemask() to use keyok() to enable/disable KEY_MOUSE, so
          that applications can disable ncurses' mouse and supply their own
          handler.
        + add extensions keyok() and define_key().  These are designed to allow
          the user's application better control over the use of function keys,
          e.g., disabling the ncurses KEY_MOUSE.  (The define_key idea was from
          a mailing-list thread started by Kenneth Albanowski
          <kjahds@kjahds.com> Nov'1995).
        + restore original behavior in ncurses 'g' test, i.e., explicitly
          set the keypad mode rather than use the default, since it confuses
          people.
        + rewrote the newdemo banner so it's readable (reported by Hugh
          Daniel).
        + tidy up exit from hashtest (reported by Hugh Daniel).
        + restore check for ^Q in ncurses 'g' test broken in 970510 (reported
          by Hugh Daniel)
        + correct tput program, checking return-value of setupterm (patch by
          Florian La Roche).
        + correct logic in pnoutrefresh() and pechochar() functions (reported
          by Kriang Lerdsuwanakij <lerdsuwa@scf.usc.edu>).  The computation
          of 'wide' date to eric's #283 (1.9.9), and the pechochar bug to the
          original implementation (1.9.6).
        + correct typo in vt102-w terminfo.src entry (patch by Robert Wuest
          <rwuest@sire.vt.com>)
        + move calls of _nc_background() out of various loops, as its return
          value will be the same for the whole window being operated on (patch
          by J T Conklin).
        + add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in
          SVr4 headers (patch by J T Conklin <jtc@NetBSD.ORG>)
        + modify glibc addon-configure scripts (patch by H.J.Lu).
        + correct a bug in hashmap.c: the size used for clearing the hashmap
          table was incorrect, causing stack corruption for large values of
          LINES, e.g., >MAXLINES/2 (patch by Alexander V. Lukyanov).
        + eric's terminfo 9.13.23 & 9.13.24 changes: replaced minitel-2 entry,
          added MGR, ansi-nt (note: the changes described for 9.13.24 have not
          been applied).
        > several changes by Juergen Pfeifer:
        + correct a missing error-return in form_driver.c when wrapping of a
          field is not possible.
        + correct logic in form_driver.c for configurations that do not have
          memccpy() (reported by Sidik Isani <isani@cfht.hawaii.edu>)
        + change several c++ binding functions to inline.
        + modify c++ menu binding to inherit from panels, for proper
          initialization.
        + correct freeing of menu items in c++ binding.
        + modify c++ binding to reflect removal of const from user data pointer
          in forms/menus libraries.

970524
        + add description of xterm-16color.
        + modify name of shared-library on *BSD to end with $(REL_VERSION)
          rather than $(ABI_VERSION) to match actual convention on FreeBSD
          (cf: 960713).
        + add OpenBSD to shared-library case, same as NetBSD and FreeBSD
          (reported by Hugh Daniel <hugh@rat.toad.com>).
        + corrected include-dependency in menu/Makefile so that "make install"
          works properly w/o first doing "make".
        + add fallback definition for isascii, used in infocmp.
        + modify xmas to use color, and to exit right away when a key is
          pressed.
        + modify gdc so that the scrolled digits function as described (there
          was no time delay between the stages, and the digits overwrote the
          bounding box without tidying up).
        + modify lib_color.c to use setaf/setab only for the ANSI color codes
          0 through 7.  Using 16 colors requires setf/setb.
        + modify ncurses 'c' test to work with 16 colors, as well as the normal
          8 colors.
        + remove const qualifier from user data pointer in forms and menus
          libraries (patch by Juergen Pfeifer).
        + rewrote 'waddchnstr()' to avoid using the _nc_waddch_nosync()
          function, thereby not interpreting tabs, etc., as per spec (patch by
          Alexander V. Lukyanov).

970517
        + suppress check for pre-existing ncurses header if the --prefix
          option is specified.
        + add configure options "--with-system-type" and
          "--with-system-release" to assist in checking the generated
          makefiles.
        + add configure option "--enable-rpath" to allow installers to specify
          that programs linked against shared libraries will have their library
          path embedded, allowing installs into nonstandard locations.
        + add flags to OSF1 shared-library options to specify version and
          symbol file (patch by Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>)
        + add missing definition for ABI_VERSION to c++/Makefile.in (reported
          by Satoshi Adachi <adachi@wisdom.aa.ap.titech.ac.jp>).
        + modify link flags to accommodate HP-UX linker which embeds absolute
          pathnames in executables linked against shared libraries (reported by
          Jason Evans <jasone@mrc.uidaho.edu>, solved by Alan Shutko
          <ats@hubert.wustl.edu>).
        + drop unnecessary check for attribute-change in onscreen_mvcur() since
          mvcur() is the only caller within the library, and that check in turn
          is exercised only from lib_doupdate.c (patch by Alexander V.
          Lukyanov).
        + add 'blank' parameter to _nc_scroll_window() so _nc_mvcur_scrolln()
          can use the background of stdscr as a parameter to that function
          (patch by Alexander V. Lukyanov).
        + moved _nc_mvcur_scrolln() from lib_mvcur.c to lib_doupdate.c, to use
          the latter's internal functions, as well as to eliminate unnecessary
          cursor save/restore operations (patch by Alexander V. Lukyanov).
        + omit parameter of ClrUpdate(), since it is called only for newscr,
          further optimized/reduced by using ClearScreen() and TransformLine()
          to get rid of duplicate code (patch by Alexander V. Lukyanov).
        + modify scrolling algorithm in _nc_scroll_optimize() to reject hunks
          that are smaller than the distance to be moved (patch by Alexander V.
          Lukyanov).
        + correct a place where the panel library was not ifdef'd in ncurses.c
          (Juergen Pfeifer)
        + documentation fixes (Juergen Pfeifer)

970515  4.1 release for upload to prep.ai.mit.edu
        + re-tag changes since 970505 as 4.1 release.

970510
        + modify ncurses 'g' test to allow mouse input
        + modify default xterm description to include mouse.
        + modify configure script to add -Wwrite-strings if gcc warnings are
          enabled while configuring --enable-const (and fixed related
          warnings).
        + add toggle, status display for keypad mode to ncurses 'g' test to
          verify that keypad and scrollok are not inherited from parent window
          during a call to newwin.
        + correction to MKexpanded.sh to make it work when configure --srcdir
          is used (reported by H.J.Lu).
        + revise test for bool-type, ensuring that it checks if builtin.h is
          available before including it, adding test for sizeof(bool) equal
          to sizeof(short), and warning user if the size cannot be determined
          (reported by Alexander V. Lukyanov).
        + add files to support configuration of ncurses as an add-on library
          for GNU libc (patch by H.J.Lu <hjl@lucon.org>)

970506
        + correct buffer overrun in lib_traceatr.c
        + modify change to lib_vidattr.c to avoid redundant orig_pair.
        + turn on 'echo()' in hanoi.c, since it is initially off.
        + rename local 'errno' variable in etip.h to avoid conflict with global
          (H.J.Lu).
        + modify configure script to cache LD, AR, AR_OPTS (patch by H.J.Lu
          <hjl@lucon.org>)

970505  4.1 pre-release
        + regenerate the misc directory html dumps without the link list, which
          is not useful.
        + correct dependency in form directory makefile which caused
          unnecessary recompiles.
        + correct substitution for ABI_VERSION in test-makefile
        + modify install rules for shared-library targets to remove the target
          before installing, since some install programs do not properly handle
          overwrite of symbolic links.
        + change order of top-level targets so that 'include' immediate
          precedes the 'ncurses' directory, reducing the time between new
          headers and new libraries (requested by Larry Virden).
        + modify lib_vidattr.c so that colors are turned off only before
          modifying other attributes, turned on after others.  This makes the
          hanoi.c program display correctly on FreeBSD console.
        + modify debug code in panel library to print user-data addresses
          rather than the strings which they (may) point to.
        + add check to ensure that C++ binding and demo are not built with g++
          versions below 2.7, since the binding uses templates.
        + modify c++ binding and demo to build and run with SGI's c++ compiler.
          (It also compiles with the Sun SparcWorks compiler, but the demo does
          not link, due to a vtbl problem).
        + corrections to demo.cc, to fix out-of-scope variables (Juergen
          Pfeifer).

970503
        + correct memory leak in _nc_trace_buf().
        + add configure test for regexpr.h, for Unixware 1.x.
        + correct missing "./" prefixing names of generated files in ncurses
          directory.
        + use single-quotes in configure scripts assignments for MK_SHARED_LIB
          to workaround shell bug on FreeBSD 2.1.5
        + remove tabs from intermediate #define's for GCC_PRINTF, GCC_SCANF
          that caused incorrect result in ncurses_cfg.h
        + correct initialization in lib_trace.c, which omitted version info.
        + remove ech, el1 attributes from cons25w description; they appear to
          malfunction in FreeBSD 2.1.5
        + correct color attributes in terminfo.src and lib_color.c to match
          SVr4 behavior by interchanging codes 1,4, 3,6 in the setf/setb
          capabilities.
        + use curs_set() rather than checks via tigetstr() for test programs
          that hide the cursor: firework, rain, worm.
        + ensure that if the terminal lacks change_scroll_region, parm_index
          and parm_rindex are used only to scroll the whole screen (patch by
          Peter Wemm).
        + correct curs_set() logic, which did not return ERR if the requested
          attributes did not exist, nor did it assume an unknown initial state
          for the cursor (patch by Alexander V. Lukyanov).
        + combine IDcTransformLine and NoIDcTransformLine to new TransformLine
          function in lib_doupdate.c (patch by Alexander V. Lukyanov).
        + correct hashmap.c, which did not update index information (patch by
          Alexander V. Lukyanov).
        + fixes for C++ binding and demo (see c++/NEWS) (Juergen Pfeifer).
        + correct index in lib_instr.c (Juergen Pfeifer).
        + correct typo in 970426 patch from Tom's cleanup of lib_overlay.c
          (patch by Juergen Pfeifer).

970426
        + corrected cost computation in PutRange(), which was using
          milliseconds compared to characters by adding two new members to the
          SCREEN struct, _hpa_ch_cost and _cup_ch_cost.
        + drop ncurses/lib_unctrl.c, add ncurses/MKunctrl.awk to generate a
          const array of strings (suggested by Alexander V. Lukyanov).  The
          original suggestion in 970118 used a perl script.
        + rewrote ncurses 'b' test to better exercise magic-cookie (xmc), as
          well as noting the attributes that are not supported by a terminal.
        + trace the computation of cost values in lib_mvcur.c
        + modify _nc_visbuf() to use octal rather than hex, corrected sign
          extension bug in that function that caused buffer overflow.
        + modify trace in lib_acs.c to use _nc_visbuf().
        + suppress trace within _traceattr2().
        + correct logic of _tracechtype2(), which did not account for repeats
          or redefinition within an acsc string.
        + modify debug-library version baudrate() to use environment variable
          $BAUDRATE to override speed computation.  This is needed for
          regression testing.
        + correct problems shown by "weblint -pedantic".
        + update mailing-list information (now ncurses@bsdi.com).

970419
        + Improve form_field_validation.3x manpage to better describe the
          precision parameter for TYPE_NUMERIC and TYPE_INTEGER.  Provide more
          precise information how the range checking can be avoided.  (patch by
          Juergen Pfeifer, reported by Bryan Henderson)
        + change type of min/max value of form types TYPE_INTEGER to long to
          match SVr4 documentation.
        + set the form window to stdscr in set_form_win() so that form_win()
          won't return null (patch by Juergen Pfeifer, reported by Bryan
          Henderson <bryanh@giraffe.netgate.net>).

970412
        + corrected ifdef'ing of inline (cf: 970321) for TRACE vs C++.
        + corrected toggle_attr_off() macro (patch by Andries Brouwer).
        + modify treatment of empty token in $MANPATH to /usr/man (reported by
          <Andries.Brouwer@cwi.nl>)
        + modify traces that record functions-called so that chtype and attr_t
          values are expressed symbolically, to simplify reuse of generated
          test-scripts on SVr4 regression testing.
        + add new trace functions _traceattr2() and _tracechtype2()

970405
        + add configure option --enable-const, to support the use of 'const'
          where XSI should have, but did not, specify.  This defines
          NCURSES_CONST, which is an empty token otherwise, for strict
          compatibility.
        + make processing of configure options more verbose by echoing the
          --enable/--with values.
        + add configure option --enable-big-core
        + set initial state of software echo off as per XSI.
        + check for C++ builtin.h header
        + correct computation of absolute-path for $INSTALL that dropped "-c"
          parameter from the expression.
        + rename config.h to ncurses_cfg.h to avoid naming-conflict when
          ncurses is integrated into larger systems (adapted from diffs by
          H.J.Lu for libc).
        + correct inequality in lib_doupdate.c that caused a single-char to not
          be updated when the char on the right-margin was not blank, idcok()
          was true (patch by Alexander V Lukyanov (in 970124), reported
          by Kriang Lerdsuwanakij <lerdsuwa@scf-fs.usc.edu> in 970329).
        + modify 'clean' rule in include/Makefile so that files created by
          configure script are removed in 'distclean' rule instead.

970328
        + correct array limit in tparam_internal(), add case to interpret "%x"
          (patch by Andreas Schwab)
        + rewrote number-parsing in ncurses.c 'd' test; it did not reset the
          value properly when non-numeric characters were given (reported by
          Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>)

970321
        + move definition of __INTERNAL_CAPS_VISIBLE before include for
          progs.priv.h (patch by David MacKenzie).
        + add configuration summary, reordered check for default include
          directory to better accommodate a case where installer is configuring
          a second copy of ncurses (reported by Klaus Weide
          <kweide@tezcat.com>)
        + moved the #define for 'inline' as an empty token from the
          $(CFLAGS_DEBUG) symbol into config.h, to avoid redefinition warning
          (reported by Ward Horner).
        + modify test for bool builtin type to use 'unsigned' rather than
          'unknown' when cross-compiling (reported by Ward Horner).

970315
        + add header dependencies so that "make install.libs" will succeed
          even if "make all" is not done first.
        + moved some macros from lib_doupdate.c to curses.priv.h to use in
          expanded functions with ATAC.
        + correct implementation of lib_instr.c; both XSI and SVr4 agree that
          the winnstr functions can return more characters than will fit on one
          line.

970308
        + modify script that generates lib_gen.c to support traces of called &
          return.
        + add new configure option "--disable-macros", for testing calls within
          lib_gen.c
        + corrected logic that screens level-checking of called/return traces.

970301
        + use new configure macro NC_SUBST to replace AC_PATH_PROG, better
          addressing request by Ward Horner.
        + check for cross-compiling before trying to invoke the autoconf
          AC_FUNC_SETVBUF_REVERSED macro (reported by Ward Horner)
        + correct/simplify loop in _nc_visbuf(), 970201 changes omitted
          a pointer-increment.
        + eliminate obsolete symbol SHARED_ABI from dist.mk (noted by
          Florian La Roche).

970215
        + add configure option --enable-expanded, together with code that
          implements an expanded form of certain complex macros, for testing
          with ATAC.
        + disable CHECK_POSITION unless --with-assertions is configured
          (Alexander V Lukyanov pointed out that this is redundant).
        + use keyname() to show traced chtype values where applicable rather
          than _tracechar(), which truncates the value to 8-bits.
        + minor fixes to TRACE_ICALLS, added T_CREATE, TRACE_CCALLS macros.
        + modify makefiles in progs and test directories to avoid using C
          preprocessor options on link commands (reported by Ward Horner)
        + correct ifdef/include-order for nc_alloc.h vs lib_freeall.c (reported
          by Ward Horner)
        + modify ifdef's to use configure-defined symbols consistently
          (reported by Ward Horner)
        + add/use new makefile symbols AR, AR_OPTS and LD to assist in non-UNIX
          ports (reported by Ward Horner <whorner@tsi-telsys.com>)
        + rename struct try to struct tries, to avoid name conflict with C++
          (reported by Gary Johnson).
        + modify worm.c to hide cursor while running.
        + add -Wcast-qual to gcc warnings, fix accordingly.
        + use PutChar rather than PutAttrChar in ClrToEOL to properly handle
          wrapping (Alexander V Lukyanov).
        + correct spurious echoing of input in hanoi.c from eric's #291 & #292
          patches (reported by Vernon C. Hoxie <vern@zebra.alphacdc.com>).
        + extend IRIX configuration to IRIX64
        + supply missing install.libs rule needed after restructuring
          test/Makefile.in

970208
        + modify "make mostlyclean" to leave automatically-generated source
          in the ncurses directory, for use in cross-compiles.
        + autogenerated object-dependencies for test directory
        + add configure option --with-rcs-ids
        + modify configuration scripts to generate major/minor/patch versions
          (suggested by Alexander V Lukyanov).
        + supply missing va_end's in lib_scanw.c
        + use stream I/O for trace-output, to eliminate fixed-size buffer
        + add TRACE_ICALLS definition/support to lib_trace.c
        + modify Ada95 binding to work with GNAT 3.09 (Juergen Pfeifer).

970201
        + add/modify traces for called/return values to simplify extraction
          for test scripts.
        + changed _nc_visbuf to quote its result, and to dynamically allocate
          the returned buffer.
        + invoke ldconfig after installing shared library
        + modify install so that overwrite applies to shared library -lcurses
          in preference to static library (reported by Zeyd M Ben-Halim 960928).
        + correct missing ';' in 961221 mod to overwrite optional use of $(LN_S)
          symbol.
        + fixes to allow "make install" to work without first doing a "make
          all" (suggested by Larry Virden).

970125
        + correct order of #ifdef for TABS_OK.
        + instrumented toe.c to test memory-leaks.
        + correct memory-deallocation in toe.c (patch by Jesse Thilo).
        + include <sys/types.h> in configuration test for regex.h (patch by
          Andreas Schwab)
        + make infocmp recognize -I option, for SVr4 compatibility (reported by
          Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>)

970118
        + add extension 'use_default_colors()', modified test applications that
          use default background (firework, gdc, hanoi, knight, worm) to
          demonstrate.
        + correct some limit checks in lib_doupdate.c exposed while running
          worm.
        + use typeCalloc macro for readability.
        + add/use definition for CONST to accommodate testing with Solaris
          (SVr4) curses, which doesn't use 'const' in its prototypes.
        + modify ifdef's in test/hashtest.c and test/view.c to compile with
          Solaris curses.
        + modify _tracedump() to pad colors & attrs lines to match change
          in 970101 showing first/last changes.
        + corrected location of terminating null on dynamically allocated forms
          fields (patch by Per Foreby).

970111
        + added headers to make view.c compile on SCO with the resizeterm()
          code (i.e., struct winsize) - though this compiles, I don't have a
          suitable test configuration since SIGWINCH doesn't pass my network to
          that machine - T.Dickey.
        + update test/configure.in to supply some default substitutions.
        + modify configure script to add -lncurses after -lgpm to fix problem
          linking against static libraries.
        + add a missing noraw() to test/ncurses.c (places noted by Jeremy
          Buhler)
        + add a missing wclear() to test/testcurs.c (patch by Jeremy Buhler
          <jbuhler@cs.washington.edu>)
        + modify headers to accommodate compilers that don't allow duplicate
          "#define" lines for NCURSES_VERSION (reported by Larry W. Virden
          <lvirden@cas.org>)
        + fix formatting glitch in curs_getch.3x (patch by Jesse Thilo).
        + modify lib_doupdate to make el, el1 and ed optimization use the
          can_clear_with macro, and change EmitRange to allow leaving cursor at
          the middle of interval, rather than always at the end (patch by
          Alexander V Lukyanov).  This was originally 960929, resync 970106.

970104
        + workaround defect in autoconf 2.12 (which terminates configuration
          if no C++ compiler is found) by adding an option --without-cxx.
        + modify several man-pages to use tbl, where .nf/.fi was used (reported
          by Jesse Thilo).
        + correct font-codes in some man-pages (patch by Jesse Thilo
          <Jesse.Thilo@pobox.com>)
        + use configure script's knowledge of existence of g++ library for the
          c++ Makefile (reported by Paul Jackson).
        + correct misleading description of --datadir configuration option
          (reported by Paul Jackson <pj@sam.engr.sgi.com>)

970101
        + several corrections to _nc_mvcur_scrolln(), prompted by a bug report
          from Peter Wemm:
        > the logic for non_dest_scroll_region was interchanged between the
          forward & reverse scrolling cases.
        > multiple returns from the function allowed certain conditions to do
          part of an operation before discovering that it couldn't be
          completed, returning an error without restoring the cursor.
        > some returns were ERR, where the function had completed the
          operation, because the insert/delete line logic was improperly
          tested (this was probably the case Peter saw).
        > contrary to comments, some scrolling cases were tested after the
          insert/delete line method.
        + modify _tracedump() to show first/last changes.
        + modify param of ClrUpdate() in lib_doupdate.c to 'newscr', fixes
          refresh problem (reported by Peter Wemm) that caused nvi to not show
          result of ":r !ls" until a ^L was typed.

961229  (internal alpha)
        + correct some of the writable-strings warnings (reported by Gary
          Johnson <gjohnson@season.com>).  Note that most of the remaining ones
          are part of the XSI specification, and can't be "fixed".
        + improve include-dependencies in form, menu, panel directories.
        + correct logic of delay_output(), which would return early if
          there is data on stdin.
        + modify interface & logic of _nc_timed_wait() to support 2 file
          descriptors, needed for GPM.
        + integrate patch by Andrew Kuchling <amk@magnet.com> for GPM (mouse)
          support, correcting logic in wgetch() and _nc_mouse_parse() which
          prevented patch from working properly -TD
        + improve performance of panel algorithm (Juergen Pfeifer 961203).
        + strip RCS id's from generated .html files in Ada95 subtree.
        + resync with generated .html files (Juergen Pfeifer 961223).
        + terminfo.src 10.1.0 (ESR).

961224  4.0 release
        + release as 4.0 to accommodate Linux ld.so.1.8.5
        + correct syntax/spelling, regenerated .doc files from .html using
          lynx 2.5
        + refined forms/menus makefiles (Juergen Pfeifer 961223).

961221  - snapshot
        + remove logic in read_entry.c that attempts to refine errno by using
          'access()' for the directory (from patch by Florian La Roche).
        + correct configure test/substitution that inhibits generating
          include-path to /usr/include if gcc is used (reported by Florian La
          Roche).
        + modify setupterm() to allocate new TERMINAL for each call, just as
          solaris' curses does (Alexander V Lukyanov 960829).
        + corrected memory leaks in read_entry.c
        + add configure options --with-dbmalloc, --with-dmalloc, and
          --disable-leaks, tested by instrumenting infocmp, ncurses programs.
        + move #include's for stdlib.h and string.h to *.priv.h to accommodate
          use of dbmalloc.
        + modify use of $(LN_S) to follow recommendation in autoconf 2.12,
          i.e., set current directory before linking.
        + split-out panel.priv.h, improve dependencies for forms, menus
          (Juergen Pfeifer 961204).
        + modify _nc_freewin() to reset globals curscr/newscr/stdscr when
          freeing the corresponding WINDOW (found using Purify).
        + modify delwin() to return ERR if the window to be deleted has
          subwindows, needed as a side-effect of resizeterm() (found using
          Purify).  Tested and found that SVr4 curses behaves this way.
        + implement logic for _nc_freeall(), bringing stub up to date.

961215
        + modify wbkgd() so that it doesn't set nulls in the rendered text,
          even if its argument doesn't specify a character (fixes test case by
          Juergen Pfeifer for bug-report).
        + set window-attributes in wbkgd(), to simplify comparison against
          Solaris curses, which does this.

961214  - snapshot
        + replace most constants in ncurses 'o' test by expressions, making it
          work with wider range of screen sizes.
        + add options to ncurses.c to specify 'e' test softkey format, and the
          number of header/footer lines to rip-off.
        + add ^R (repaint after resize), ^L (refresh) commands to ncurses 'p'
          test.
        + add shell-out (!) command to ncurses 'p' test to allow test of
          resize between endwin/refresh.
        + correct line-wrap case in mvcur() by emitting carriage return,
          overlooked in 960928, but needed due to SVr4 compatibility changes to
          terminal modes in 960907.
        + correct logic in wresize that causes new lines to be allocated,
          broken for the special case of increasing rows only in 960907's fix
          for subwindows.
        + modify configure script to generate $(LDFLAGS) with -L and -l options
          in preference to explicit library filenames.  (NOTE: this may
          require further amending, since I vaguely recall a dynamic loader
          that did not work properly without the full names, but it should be
          handled as an exception to the rule, since some linkers do bulk
          inclusion of libraries when given the full name - T.Dickey).
        + modify configure script to allow user-supplied $CFLAGS to set the
          debug-option in all libraries (requested by lots of people) -TD
        + use return consistently from main(), rather than exit (reported by
          Florian La Roche).
        + add --enable-getcap-cache option to configure, normally disabled
          (requested by Florian La Roche).
        + make configure test for gettimeofday() and possibly -lbsd more
          efficient (requested by Florian La Roche <florian@knorke.saar.de>)
        + minor adjustments to Ada95 binding (patches by Juergen Pfeifer)
        + correct attributes after emitting orig_pair in lib_vidattr.c (patch
          by Alexander V Lukyanov).

961208
        + corrected README wrt Ada95 (Juergen Pfeifer)

961207  - snapshot
        + integrate resizeterm() into doupdate(), so that if screen size
          changes between endwin/refresh, ncurses will resize windows to fit
          (this needs additional testing with pads and softkeys).
        + add, for memory-leak testing, _nc_freeall() entrypoint to free all
          data used in ncurses library.
        + initialize _nc_idcok, _nc_idlok statically to resolve discrepancy
          between initscr() and newwin() initialization (reported by
          Alexander V Lukyanov).
        + test built VERSION=4.0, SHARED_ABI=4 with Linux ld.so.1.8.5
          (set beta versions to those values -- NOTE that subsequent pre-4.0
          beta may not be interchangeable).
        + modify configure script to work with autoconf 2.12

961130  1.9.9g release
        + add copyright notices to configuration scripts (written by Thomas
          Dickey).

961127
        > patch, mostly for panel (Juergen Pfeifer):
        + cosmetic improvement for a few routines in the ncurses core library
          to avoid warning messages.
        + the panel overlap detection was broken
        + the panel_window() function was not fool-proof.
        + Some inlining...
        + Cosmetic changes (also to avoid warning messages when compiling with
          -DTRACE).

961126
        > patch by Juergen Pfeifer:
        + eliminates warning messages for the compile of libform.
        + inserts Per Foreby's new field type TYPE_IPV4 into libform.
        + Updates man page and the Ada95 binding to reflect this.
        + Improves inlining in libmenu and libform.

961120
        + improve the use of the "const" qualifier in the
          panel library (Juergen Pfeifer)
        + change set_panel_userptr() and panel_userptr() to use void*
          (Juergen Pfeifer)

961119
        + change ABI to 3.4
        + package with 961119 version of Ada95 binding (fixes for gnat-3.07).
          (Juergen Pfeifer)
        + correct initialization of the stdscr pseudo panel in panel library
          (Juergen Pfeifer)
        + use MODULE_ID (rcs keywords) in forms and menus libraries (Juergen
          Pfeifer).
        > patch #324 (ESR):
        + typo in curs_termcap man page (reported by Hendrik Reichel
          <106065.2344@compuserve.com>)
        + change default xterm entry to xterm-r6.
        + add entry for color_xterm

961116  - snapshot
        + lint found several functions that had only #define implementations
          (e.g., attr_off), modified curses.h.in to generate them as per XSI
          Curses requirement that every macro be available as a function.
        + add check in infocmp.c to guard against string compare of
          CANCELLED_STRING values.
        + modify firework.c, rain.c to hide cursor while running.
        + correct missing va_end in lib_tparm.c
        + modify hanoi.c to work on non-color terminals, and to use timing
          delays when in autoplay mode.
        + correct 'echochar()' to refresh immediately (reported by Adrian
          Garside <94ajg2@eng.cam.ac.uk>)
        > patch #322 (ESR):
        + reorganize terminfo.src entries for xterm.

961109  - snapshot
        + corrected error in line-breakout logic (lib_doupdate.c)
        + modified newdemo to use wgetch(win) rather than getch() to eliminate
          a spurious clear-screen.
        + corrected ifdef's for 'poll()' configuration.
        + added modules to ncurses, form, menu for Ada95 binding (Juergen
          Pfeifer).
        + modify set_field_buffer() to allow assignment of string longer than
          the initial buffer length, and to return the complete string rather
          than only the initial size (Juergen Pfeifer and Per Foreby
          <perf@efd.lth.se>).

961102  - snapshot
        + configure for 'poll()' in preference to 'select()', since older
          systems are more likely to have a broken 'select()'.
        + modified render_char() to avoid OR'ing colors.
        + minor fixes to testcurs.c, newdemo.c test programs: ifdef'd out the
          resize test, use wbkgd and corrected box() parameters.
        + make flushinp() test work in ncurses.c by using napms() instead of
          sleep().
        + undo ESR's changes to xterm-x11r6 (it no longer matched the X11R6.1
          distribution, as stated)
        + terminfo 9.13.18 resync (ESR)
        + check for getenv("HOME") returning null (ESR).
        + change buffer used to decode xterm-mouse commands to unsigned to
          handle displays wider than 128 chars (Juergen Pfeifer).
        + correct typo curs_outopts.3x (Juergen Pfeifer).
        + correct limit-checking in wenclose() (Juergen Pfeifer).
        + correction to Peter Wemm's newwin change (Thomas Fehr
          <fehr@suse.de>).
        + corrections to logic that combines colors and attributes; they must
          not be OR'd (Juergen Pfeifer, extending from report/patch by Rick
          Marshall).

961026  - snapshot
        + reset flags in 'getwin()' that might cause refresh to attempt to
          manipulate the non-existent parent of a window that is read from a
          file (lib_screen.c).
        + restructure _nc_timed_wait() to log more information, and to try to
          recover from badly-behaved 'select()' calls (still testing this).
        + move define for GOOD_SELECT into configure script.
        + corrected extra '\' character inserted before ',' in comp_scan.c
        + corrected expansion of %-format characters in dump_entry.c; some were
          rendered as octal constants.
        + modify dump_entry.c to make terminfo output more readable and like
          SVr4, by using "\s" for spaces (leading/trailing only), "\," for
          comma, "\^" and "\:" as well.
        + corrected some memory leaks in ncurses.c, and a minor logic error
          in the top-level command-parser.
        + correction for label format 4 (PC style with info line), a
          slk_clear(), slk_restore() sequence didn't redraw the info line
          (Juergen Pfeifer).
        + modified the slk window (if simulated) to inherit the background and
          default character attributes from stdscr (Juergen Pfeifer).
        + corrected limit-check in set_top_row (Juergen Pfeifer).

961019  - snapshot
        + correct loop-limit in wnoutrefresh(), bug exposed during pipe-testing
          had '.lastchar' entry one beyond '._maxx'.
        + modify ncurses test-program to work with data piped to it.
        + corrected pathname computation in run_tic.sh, removing extra "../"
          (reported by Tim Mooney).
        + modified configure script to use previous install's location for
          curses.h
        + added NetBSD and FreeBSD to platforms that use --prefix=/usr as
          a default.

961013
        + revised xterm terminfo descriptions to reflect the several versions
          that are available.
        + corrected a pointer reference in dump_entry.c that didn't test if
          the pointer was -1.

961005  - snapshot
        + correct _nc_mvcur_scrolln for terminals w/o scrolling region.
        + add -x option to hashtest to control whether it allows writes to the
          lower-right corner.
        + ifdef'd (NCURSES_TEST) the logic for _nc_optimize_enable to make it
          simpler to construct tests (for double-check of _nc_hash_map tests).
        + correct ifdef's for c++ in curses.h
        + change default xterm type to xterm-x11r6.
        + correct quoting in configure that made man-pages installed with
          $datadir instead of actual terminfo path.
        + correct whitespace in include/Caps, which caused kf11, clr_eol and
          clr_end to be omitted from terminfo.5
        + fix memory leaks in delscreen() (adapted from Alexander V Lukyanov).
        + improve appearance of marker in multi-selection menu (Juergen
          Pfeifer)
        + fix behavior for forms with all fields inactive (Juergen Pfeifer)
        + document 'field_index()' (Juergen Pfeifer)
        > patch #321 (ESR):
        + add some more XENIX keycap translations to include/Caps.
        + modify newwin to set initial state of each line to 'touched'
          (from patch by Peter Wemm <peter@spinner.dialix.com>)
        + in SET_TTY, replace TCSANOW with TCSADRAIN (Alexander V Lukyanov).

960928  - snapshot
        + ifdef'd out _nc_hash_map (still slower)
        + add graphic characters to vt52 description.
        + use PutAttrChar in ClrToEOL to ensure proper background, position.
        + simplify/correct logic in 'mvcur()' that does wrapping; it was
          updating the position w/o actually moving the cursor, which broke
          relative moves.
        + ensure that 'doupdate()' sets the .oldindex values back to a sane
          state; this was causing a spurious refresh in ncurses 'r'.
        + add logic to configure (from vile) to guard against builders who
          don't remove config.cache & config.status when doing new builds -TD
        + corrected logic for 'repeat_char' in EmitRange (cf: eric #317), which
          did not follow the 2-parameter scheme specified in XSI.
        + corrected logic of wrefresh, wnoutrefresh broken in #319, making
          clearok work properly (report by Michael Elkins).
        + corrected problem with endwin introduced by #314 (removing the
          scrolling-region reset) that broke ncurses.c tests.
        + corrected order of args in AC_CHECK_LIB (from report by Ami Fischman
          <fischman@math.ucla.edu>).
        + corrected formatting of terminfo.5 tables (Juergen Ehling)
        > patch 320 (ESR):
        + change ABI to 3.3
        + emit a carriage-return in 'endwin()' to workaround a kernel bug in
          BSDI.  (requested by Mike Karels <karels@redrock.bsdi.com>)
        + reverse the default o configure --enable-termcap (consensus).
        > patch 319 (ESR):
        + modified logic for clearok and related functions (from report by
          Michael Elkins) - untested
        > patch 318 (ESR):
        + correction to #317.
        > patch 317 (ESR):
        + re-add _nc_hash_map
        + modify EmitRange to maintain position as per original design
          (patch by A. Lukyanov).
        + modify test/ncurses.c and tputs, etc., to allow trace counting
          output characters.
        + add hashtest.c program to time the hashmap optimization.
        > patch 316 (ESR):
        + add logic to deal with magic-cookie (how was this tested?)
          (lib_doupdate.c).
        + add ncurses.c driver for magic-cookie, some fixes to ncurses.c
        > patch 315 (ESR):
        + merge changes to lib_doupdate.c to use ech and rep - untested
          (patch by Alexander V Lukyanov).
        + modified handling of interrupted system calls - untested
          (lib_getch.c, lib_twait.c).
        + new function _nc_mvcur_resume()
        + fix return value for 'overlay()', 'overwrite()'

960914  - snapshot
        + implement subwindow-logic in wresize, minor fixes to ncurses 'g'
          test.
        + corrected bracketing of fallback.c (reported/suggested fix by Juergen
          Ehling <eh@eclipse.aball.de>).
        + update xterm-color to reflect XFree86 3.1.3G release.
        + correct broken dtterm description from #314 patch (e.g., spurious
          newline.  The 'pairs' change might work, but no one's tested it
          either ;-)
        + clarify the documentation for the builtin form fieldtypes (Juergen
          Pfeifer)
        > patch 314 (ESR):
        + reset scroll region on startup rather than at wrapup time
          (enhancement suggested by Alexander V Lukyanov).
        + make storage of palette tables and their size counts per-screen for
          multi-terminal applications (suggested by Alexander V Lukyanov).
        + Improved error reporting for infotocap translation errors.
        + Update terminfo.src to 9.13.14.

960907  - snapshot

          problem reported by John M. Flinchbaugh <glynis@netrax.net>)
        + modify ncurses 'f' test to accommodate terminal responses to C1 codes
          (and split up this screen to accommodate non-ANSI terminals).
        + test enter_insert_mode and exit_insert_mode in has_ic().
        + removed bogus logic in mvcur that assumes nl/nonl set output modes
          (XSI says they are input modes; SVr4 implements this).
        + added macros SET_TTY, GET_TTY to term.h
        + correct getstr() logic that altered terminal modes w/o restoring.
        + disable ICRNL, etc., during initialization to match SVr4, removing
          the corresponding logic from raw, cbreak, etc.
        + disable ONLCR during initialization, to match SVr4 (this is needed
          for cursor optimization when the cursor-down is a newline).
        + replaced ESR's imitation of wresize with my original (his didn't
          work).

960831  - snapshot
        + memory leaks (Alexander V. Lukyanov).
        + modified pnoutrefresh() to be more tolerant of too-large screen

          Muyter)
        + correct "tic -s" to take into account -I, -C options.
        + modify ncurses 'f' test to not print codes 80 through 9F, since they
          are considered control codes by ANSI terminals.

960824  - snapshot
        + correct speed variable-type in 'tgetent()' (reported by Peter Wemm)
        + make "--enable-getcap" configuration-option work (reported by
          Peter Wemm <peter@spinner.DIALix.COM>)

        + corrected typo in dtterm description.
        > patch 313 (ESR):

        + refine configure-test for "-g" option (Tim Mooney).
        + correct interaction between O_BLANK and NEW_LINE request in form
          library (Juergen Pfeifer)

960804
        + revised fix to tparm; previous fix reversed parameter order.
        > patch 312 (ESR):
          correct terminfo.src corrupted by #310
        > patch 311 (ESR):
        + fix idlok() and idcok() and the default of the idlok switch (report
          by Ville Sulko).

960803  - snapshot
        + corrected tparm to handle capability strings without explicit pop
          (reported by William P Setzer)
        + add fallback def for GCC_NORETURN, GCC_UNUSED for termcap users
          (reported by Tim Mooney).
        > patch 310 (ESR):

960730
        + eliminate quoted includes in ncurses subdirectory, ensure config.h
          is included first.
        + newterm initializes terminal settings the same as initscr (reported
          by Tim Mooney).

960727  - snapshot
        + call cbreak() in initscr(), as per XSI & SVr4.
        + turn off hardware echo in initscr() as per XSI & SVr4

        + add more checks to terminfo parser.
        + add more symbols to infocmp.

960720  - snapshot
        + save previous-attribute in lib_vidattr.c if SP is null (reported by
          Juergen Fluk <louis@dachau.marco.de>)
        + corrected calls on _nc_render so that background character is set
          as per XSI.
        + corrected wbkgdset macro (XSI allows background character to be
          null), and tests that use it.
        + more corrections to terminfo (xterm & rxvt)
        + undid change to mcprint prototype (cannot use size_t in curses.h
          because not all systems declare it in the headers that we can safely
          include therein).
        + move the ifdefs for errno into curses.priv.h
        > patch 308 (ESR):
        + terminfo changes (9.3.8)
        + modified logic of error-reporting in terminfo parser
        + fix option-processing bug in toe.

        + patch 306 (ESR):
        + moved logic that filters out rmul and rmso from setupterm to newterm
          where it is less likely to interfere with termcap applications.
        + cosmetic fixes to test/ncurses.c
        + modify open() call in ncurses/read_entry.c to use O_RDONLY symbol
          rather than constant (report by mib).
        + misc/terminfo.src sgr0 and acsc changes (report by Philippe De
          Muyter).
        + modify ncurses/comp_parse.c so that entries containing a "+" can
          have missing rmcup vs smcup.

960707
        + rollback ESR's #305 change to terminfo.src (it breaks existing
          applications, e.g., 'less 290').
        + correct path of edit_man.sh, and fix typo that made all man-pages
          preformatted.
        + restore man/menu_requestname.3x omitted in Zeyd's resync (oops).
        + auto-configure the GCC_PRINTFLIKE/GCC_SCANFLIKE macros (reported by

        + filter out rmul, rmso that conflict with sgr0 when reading terminal
          descriptions.
        + work around autoconf bug, force $INSTALL to absolute path
          (reported by Zeyd).
        + modify man-page install for BSDI to install preformatted .0 files
          (reported by David MacKenzie).
        + add/use gcc __attribute__ for printf and scanf in curses.h
        + added SGR attributes test-case to ncurses
        + revised ncurses 't' logic to show trace-disable effect in the menu.

        + make ncurses 'p' legend toggle with '?'
        + disable scrollok during the ncurses 'p' test; if it is enabled the
          stdscr will scroll when putting the box-corners in the lower-right
          of the screen.
        > patch 305 (ESR):

960629  - snapshot
        + check return code of _nc_mvcur_scrolln() in _nc_scroll_optimize() for
          terminals with no scrolling-support (reported by Nikolay Shadrin
          <queen@qh.mirea.ac.ru>)
        + added ^S scrollok-toggle to ncurses 'g' test.
        + added ^T trace-toggle to ncurses tests.
        + modified ncurses test program to use ^Q or ESC consistently for
          terminating tests (rather than ^D), and to use control keys rather
          than function keys in 'g' test.
        + corrected misplaced wclrtoeol calls in addch to accommodate wrapping
          (reported by Philippe De Muyter).
        + modify lib_doupdate.c to use effective costs to tradeoff between
          delete-character/insert-character vs normal updating (reported by
          David MacKenzie).
        + compute effective costs for screen update operations (e.g., clr_eos,
          delete_character).
        + corrected error in knight.c exposed by wrap fixes in 960622; the
          msgwin needed scrollok set.
        + corrected last change to IDcTransformLine logic to avoid conflict
          between PutRange and InsStr
        + modified run_tic.sh to not use /usr/tmp (reported by David

          set.
        + corrected off-by-one in RoomFor call in read_entry.c

960622  - snapshot
        + modified logic that wraps cursor in addch to follow the XSI spec,
          (implemented in SVr4) which states that the cursor position is
          updated when wrapping.  Renamed _NEED_WRAP to _WRAPPED to reflect the
          actual semantics.
        + added -s option to tic, to provide better diagnostics in run_tic.sh
        + improved error-recovery for tabset install.
        + change ABI to 3.1 (dropped tparam, corrected getbkgd(), added
          _yoffset to WINDOW).
        + modified initialization of SP->_ofp so that init_acs() is called with
          the "right" file pointer (reported by Rick Marshall <rjm@nlc.net.au>
        + documentation fixes (Juergen Pfeifer).
        + corrected, using new SCREEN and WINDOW members, the behavior of
          ncurses if one uses ripoffline() to remove a line from the top of the
          screen (Juergen Pfeifer).
        + modified autoconf scripts to prepare for Ada95 (GNAT) binding to
          ncurses (Juergen Pfeifer).
        + incorrect buffer-size in _nc_read_entry, reported by ESR.

960617
        + corrected two logic errors in read_entry.c, write_entry.c (called by
          tic, the write/read of terminfo entries used inconsistent rules for
          locating the entries; the $TERMINFO_DIRS code would find only the
          first entry in a list).
        + refined pathname computation in run_tic.sh and shlib.
        + corrected initialization of $IP in misc/run_tic.sh

960615  - snapshot
        + ifdef'd out _nc_hash_map() call because it does not improve speed.
        + display version of gcc if configure script identifies it.
        + modify configure script to use /usr as Linux's default prefix.
        + modify run_tic.sh to use shlib script, fixes some problems installing
          with a shared-library configuration.
        + adjusted configure script so that it doesn't run tests with the
          warnings turned on, which makes config.log hard to read.
        + added 'lint' rule to top-level Makefile.
        + added configure option '--with-install-prefix' for use by system
          builders to install into staging locations (requested by
          Charles Levert <charles@comm.polymtl.ca>).
        + corrected autoconfigure for Debian man program; it's not installed
          as "man_db".
        + set noecho in 'worm'; it was ifdef'd for debug only
        + updated test/configure.in for timing-display in ncurses 'p' test
        + corrected misspelled 'getbkgd()'.
        + corrected wbkgdset to work like observed syvr4 (sets A_CHARTEXT part
          to blank if no character given, copies attributes to window's
          attributes).
        + modified lib_doupdate.c to use lower-level SP's current_attr state
          instead of curscr's state, since it is redundant.
        + correction to IDcTransformLine logic which controls where InsStr is
          invoked (refined by Alexander V Lukyanov).
        > patch 303 (ESR):
        + conditionally include Chris Torek's hash function _nc_hash_map().

        + flush output when changing cursor-visibility (Rick Marshall)
        + fix a minor bug in the _nc_ripoff() routine and improve error
          checking when creating the label window (Juergen Pfeifer).
        + enhancement to the control over the new PC-style soft key format.
          allow caller now to select whether or not one wants to have

          <lav@yars.free.net>).
        + autoconf mods (Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>).
        + locale fix for forms (Philippe De Muyter <phdemuyt@ulb.ac.be>)
        + renamed "--with-datadir" option to "--with-ticdir" to avoid
          confusion, and made this check for the /usr/lib/terminfo pre-existing
          directory.

          is not part of X/Open Curses).
        + removed boolean version of 'getm'.
        + misc cursor & optimization fixes.

960504  - snapshot

### ncurses-1.9.8a -> 1.9.9e

* fixed broken wsyncup()/wysncdown(), as a result wnoutrefresh() now has
  copy-changed-lines behavior.
* added and documented wresize() function.
* more fixes to LOWER-RIGHT corner handling.
* changed the line-breakout optimization code to allow some lines to be
  emitted before the first check.
* added option for tic to use symbolic instead of hard links (for AFS)
* fix to restore auto-wrap mode.
* trace level can be controlled by environment variable.
* better handling of NULs in terminal descriptions.
* improved compatibility with observed SVR4 behavior.
* the refresh behavior of over-lapping windows is now more efficient and
  behaves like SVR4.
* use autoconf 2.7, which results in a working setup for SCO 5.0.
* support for ESCDELAY.
* small fixes for menu/form code.
* the test directory has its own configure.
* fixes to pads when optimizing scrolling.
* fixed several off-by-one bugs.
* fixes for termcap->terminfo translation; less restrictions more correct
  behavior.

### ncurses-1.9.7 -> 1.9.8a

* teach infocmp -i to recognize ECMA highlight sequences
* infocmp now dumps all SVr4 termcaps (not just the SVr4 ones) on -C
* support infocmp -RBSD.
* satisfy XSI Curses requirement that every macro be available as a function.
* This represents the last big change to the public interface of ncurses. The
  ABI_VERSION has now been set at 3.0 and should stay there barring any great
  catastrophies or acts of God.
* The C++ has been cleaned up in reaction to the changes to satisfy XSI's
  requirements.
* libncurses now gets linked to libcurses to help seamless emulation
  (replacement) of a vendor's curses. --disable-overwrite turns this behavior
  off.

### ncurses-1.9.6 -> 1.9.7

* corrected return values of setupterm()
* Fixed some bugs in tput (it does padding now)
* fixed a bug in tic that made it do the wrong thing on entries with more than
  one `use' capability.
* corrected the screen-size calculation at startup time to alter the
  numeric capabilities as per SVr4, not just LINES and COLS.
* toe(1) introduced; does what infocmp -T used to.
* tic(1) can now translate AIX box1 and font[0123] capabilities.
* tic uses much less core, the dotic.sh kluge can go away now.
* fix read_entry() and write_entry() to pass through cancelled capabilities OK.
* Add $HOME/.terminfo as source/target directory for terminfo entries.
* termcap compilation now automatically dumps an entry to $HOME/.terminfo.
* added -h option to toe(1).
* added -R option to tic(1) and infocmp(1).
* added fallback-entry-list feature.
* added -i option to infocmp(1).
* do a better job at detecting if we're on SCO.

### ncurses-1.9.5 -> 1.9.6

* handling of TERMCAP environment variables now works correctly.
* various changes to shorten termcap translations to less that 1024 chars.
* tset(1) added
* mouse support for xterm.
* most data tables are now const and accordingly live in shareable text space.
* Obey the XPG4/SVr4 practice that echo() is initially off.
* tic is much better at translating XENIX and AIX termcap entries now.
* tic can interpret ko capabilities now.
* integrated Juergen Pfeifer's forms library.
* taught write_entry() how not to write more than it needs to; this change
  reduces the size of the terminfo tree by a full 26%!
* infocmp -T option added.
* better warnings about historical tic quirks from tic.

### ncurses 1.9.4 -> 1.9.5

* menus library is now included with documentation.
* lib_mvcur has been carefully profiled and tuned.
* Fixed a ^Z-handling bug that was tanking lynx(1).
* HJ Lu's patches for ELF shared libraries under Linux
* terminfo.src 9.8.2
* tweaks for compiling in separate directories.
* Thomas Dickey's patches to support NeXT's brain-dead linker
* Eric Raymond's patches to fix problems with long termcap entries.
* more support for shared libraries under SunOS and IRIX.

### ncurses 1.9.3 -> 1.9.4

* fixed an undefined-order-of-evaluation bug in lib_acs.c
* systematically gave non-API public functions and data an _nc_ prefix.
* integrated Juergen Pfeifer's menu code into the distribution.
* totally rewrote the knight test game's interface

### ncurses 1.9.2c -> 1.9.3

* fixed the TERMCAP_FILE Support.
* fixed off-by-one errors in scrolling code
* added tracemunch to the test tools
* took steps to cut the running time of make install.data

### ncurses 1.9.2c -> 1.9.2d

* revised 'configure' script to produce libraries for normal, debug,
  profile and shared object models.

### ncurses 1.9.1 -> 1.9.2

* use 'autoconf' to implement 'configure' script.
* panels support added
* tic now checks for excessively long termcap entries when doing translation
* first cut at eliminating namespace pollution.

### ncurses 1.8.9 -> 1.9

* cleanup gcc warnings for the following: use size_t where 'int' is not
  appropriate, fixed some shadowed variables, change attr_t to compatible with
  chtype, use attr_t in some places where it was confused with 'int'.
* use chtype/attr_t casts as appropriate to ensure portability of masking
  operations.
* added-back waddchnstr() to lib_addstr.c (it had been deleted).
* supplied missing prototypes in curses.h
* include <termcap.h> in lib_termcap.c to ensure that the prototypes
  are consistent (they weren't).
* corrected prototype of tputs in <termcap.h>
* rewrote varargs parsing in lib_tparm.c (to avoid referencing memory
  that may be out of bounds on the stack) -- Purify found this.
* ensure that TRACE is defined in lib_trace.c (to solve prototype
  warnings from gcc).
* corrected scrolling-region size in 'mvcur_wrap()'
* more spelling fixes
* use 'calloc()' to allocate WINDOW struct in lib_newwin.c (Purify).
* set default value for SP->_ofp in lib_set_term.c (otherwise SunOS dumps
  core in init_acs()).
* include <errno.h> in write_entry.c (most "braindead" includes declare errno
  in that file).

### ncurses 1.8.8 -> 1.8.9

* compile (mostly) clean with gcc 2.5.8 -Wall -Wstrict-prototypes
  -Wmissing-prototypes -Wconversion and using __attribute__ to flush out
  non-portable use of "%x" for pointers, or for chtype data (which is declared
  as a long).
* modified doupdate to ensure that typahead was turned on before attempting
  select-call (otherwise, some implementations hang).
* added trace mask TRACE_FIFO, use this in lib_getch.c to allow finer
  resolution of traces.
* improved bounds checking on several critical functions.
* the data directory has been replaced by the new master terminfo file.
* -F file-comparison option added to infocmp.
* compatibility with XSI Curses is now documented in the man bages.
* wsyncup/wsyncdown functions are reliable now; subwindow code in general
  is much less flaky.
* capabilities ~msgr, tilde_glitch, insert_padding, generic_type, no_pad_char,
  memory_above, memory_below, and hard_copy are now used properly.
* cursor-movement optimization has been completely rewritten.
* vertical-movement optimization now uses hardware scrolling, il, dl.

### ncurses 1.8.7 -> 1.8.8
* untic no longer exists, infocmp replaces it.
* tic can understand termcap now, especially if it is called captoinfo.
* The Linux Standard Console terminfo entry is called linux insead of console.
  It also uses the kernel's new method of changing charsets.
* initscr() will EXIT upon error (as the docs say) This will mostly happen if
  you try to run on an undefined terminal.
* I can get things running on AIX but tic can't compile terminfo. I have to
  compile entries on another machine. Volunteers to hunt this bug are welcome.
* wbkgd() and wbkgdset() can be used to set a windows background to color.
  wclear()/werase() DO NOT use the current attribute to clear the screen.
  This is the way SVR4 curses works. PDCurses 2.1 is broken in this respect,
  though PDCurses 2.2 has been fixed.
* cleaned up the test/ directory.
* test/worm will segfault after quite a while.
* many spelling corrections courtesy of Thomas E. Dickey

### ncurses 1.8.6 -> 1.8.7
* cleaned up programs in test/ directory.
* fixed wbkgdset() macro.
* modified getstr() to stop it from advancing cursor in noecho mode.
* modified linux terminfo entry to work with the latest kernel to get
  the correct alternate character set.
* also added a linux-mono entry for those running on monochrome screens.
* changed initscr() so that it behaves like the man page says it does.
  this fixes the problem with programs in test/ crashing with SIGSEV if
  a terminal is undefined.
* modified addch() to avoid using any term.h #define's
* removed duplicate tgoto() in lib_tparm.c
* modified dump_entry.c so that infocmp deals correctly with ',' in acsc
* modified delwin() to correctly handle deleting subwindows.
* fixed Makefile.dist to stop installing an empty curses.h
* fixed a couple of out-of-date notes in man pages.

### ncurses 1.8.5 -> 1.8.6
* Implemented wbkgd(), bkgd(), bkgdset(), and wbkgdset().
* The handling of attributes has been improved and now does not turn off color
  if other attributes are turned off.
* scrolling code is improved. Scrolling in subwindows is still broken.
* Fixes to several bugs that manifest them on platforms other than Linux.
* The default to meta now depends on the status of the terminal when ncurses
  is started.
* The interface to the tracing facility has changed.  Instead of the pair of
  functions traceon() and traceoff(), there is just one function trace() which
  takes a trace mask argument.  The trace masks, defined in curses.h, are
  as follows:

        #define TRACE_DISABLE   0x00    /* turn off tracing */
        #define TRACE_ORDINARY  0x01    /* ordinary trace mode */
        #define TRACE_CHARPUT   0x02    /* also trace all character outputs */
        #define TRACE_MAXIMUM   0x0f    /* maximum trace level */

  More trace masks may be added, or these may be changed, in future releases.
* The pad code has been improved and the pad test code in test/ncurses.c has
  been improved.
* The prototype ansi entry has been changed to work with a wider variety
  of emulators.
* Fix to the prototype ansi entry that enables it to work with PC emulators
  that treat trailing ";m" in a highlight sequence as ";0m"; this doesn't
  break operation with any emulators.
* There are now working infocmp, captoinfo, tput, and tclear utilities.
* tic can now compile entries in termcap syntax.
* Core-dump bug in pnoutrefresh fixed.
* We now recognize and compile all the nonstandard capabilities in Ross
  Ridge's mytinfo package (rendering it obsolete).
* General cleanup and documentation improvements.
* Fixes and additions to the installation-documentation files.
* Take cursor to normal mode on endwin.

### ncurses 1.8.4 -> 1.8.5
* serious bugs in updating screen which caused erratic non-display,
  fixed.
* fixed initialization for getch() related variable which cause
  unpredictable results.
* fixed another doupdate bug which only appeared if you have
  parm_char.
* implemented redrawln() and redrawwin().
* implemented winsnstr() and related functions.
* cleaned up insertln() and deleteln() and implemented (w)insdeln().
* changed Makefile.dist so that installation of man pages will
  take note of the terminfo directory.
* fixed Configure (removed the mysterious 'X').
* Eric S. Raymond fixed the script.* files so that they work with
  stock awk.

#### ncurses 1.8.3 -> 1.8.4 #### ####
* fixed bug in refreshing the screen after return from shell_mode.
  There are still problems but they don't manifest themselves on
  my machine (Linux 0.99.14f).
* added wgetnstr() and modified things accordingly.
* fixed the script.src script.test to work with awk not just gawk.
* Configure can now take an argument of the target system.
* added test/ncurses.c which replaces several other programs and
  performs more testing.
[Thanks to Eric S Raymond for the last 4]
* more fixes to lib_overlay.c and added test/over.c to illustrate
  how it works.
* fixed ungetch() to take int instead of ch.
* fixes to cure wgetch() if flushinp() is called.

One note I forgot to mention in 1.8.3 is that tracing is off by
default starting in the version. If you want tracing output, put
traceon(); in your code and link with -ldcurses.

#### ncurses 1.8.2 -> ncurses 1.8.3 #### ####
MAJOR CHANGES:
1) The order of capabilities has been changed in order to achieve
binary compatibility with SVR4 terminfo database. This has the
unfortunate effect of breaking application currently linked with
ncurses. To ensure correct behavior, recompile all such programs.
Most programs using color or newer capabilities will break, others
will probably continue to work ok.

2) Pavel Curtis has renounced his copyright to the public domain.
This means that his original sources (posted to comp.sources.unix,
volume 1) are now in the public domain.  The current sources are
NOT in the public domain, they are copyrighted by me.  I'm
entertaining ideas on what the new terms ncurses is released under.

3) Eric S. Raymond has supplied a complete set of man pages for
ncurses in ?roff format. They will eventually replace most of the
current docs. Both sets are included in this release.

Other changes and notes from 1.8.2 include:
* SIGSEGV during scrolling no longer occurs.
* Other problems with scrolling and use of idl have been corrected.
* lib_getch.c has been re-written and should perform flawlessly.
  please use test/getch.c and any other programs to test this.
* ripoffline() is implemented (Thanks to Eric) and slk_ functions
  changed accordingly.
* I've added support for terminals that scroll if you write in the
  bottom-right corner.
* fixed more bugs in pads code. If anybody has a program that uses
  pads I'd love a copy.
* correct handling for terminal with back_color_erase capability
  (such as Linux console, and most PC terminals)
* ^Z handling apparently didn't work (I should never trust code
  sent me to me without extensive testing). It now seems to be
  fixed. Let me know if you have problems.
* I've added support for Apollo and NeXT, but it may still be
  incomplete, especially when dealing with the lack of POSIX
  features.
* scrolling should be more efficient on terminals with idl
  capabilities. Please see src/lib_scroll.c for more notes.
* The line drawing routines were offset by 1 at both ends. This
  is now fixed.
* added a few missing prototypes and macros (e.g. setterm())
* fixed code in src/lib_overlay.c which used to crash.
* added a few more programs in test/ The ones from the PDCurses
  package are useful, especially if you have SVR4 proper. I'm
  interested in the results you get on such a systems (Eric? ;-).
  They already exposed certain bugs in ncurses.
* See src/README for porting notes.
* The C++ code should really replace ncurses.h instead of working
  around it. It should avoid name-space clashes with nterm.h (use
  rows instead of lines, etc.)
* The C++ should compile ok. I've added explicit rules to the
  Makefile because no C++ defaults are documented on the suns.
* The docs say that echo() and nocbreak() are mutually exclusive.
  At the moment ncurses will switch to cbreak() if the case above
  occurs. Should it continue to do so? How about echo() and noraw()?
* PDCurses seem to assume that wclear() will use current attribute
  when clearing the screen. According to Eric this is not the case
  with SVR4.
* I have discovered, to my chagrin, SunOS 4.x (and probably other systems)
  * doesn't have vsscanf and God knows what else!  I've will do a vsscanf().
* I've also found out that the src/script.* rely on gawk and will not
  work with stock awk or even with nawk. Any changes are welcome.
* Linux is more tolerant of NULL dereferences than most systems. This
  fact was exposed by hanoi.
* ncurses still seems inefficient in drawing the screen on a serial
  link between Linux and suns. The padding may be the culprit.
* There seems to be one lingering problem with doupdate() after shelling
  out. Despite the fact the it is sending out the correct information
  to the terminal, nothing takes effect until you press ^L or another
  refresh takes place. And yes, output does get flushed.

#### ncurses 1.8.1 -> ncurses 1.8.2 #### Nov 28, 1993 ####

* added support for SVR4 and BSDI's BSD/386.
* major update and fix to scrolling routine.
* MORE fixes to stuff in lib_getch.c.
* cleaned-up configuration options and can now generate
        Config.* files through an awk script.
* changed setupterm() so it can be called more than once,
        add added set_curterm(), del_curterm().
* a few minor cleanups.
* added more prototypes in curses.h

* a few code cleanups.

#### ncurses 0.7.2/0.7.3 -> ncurses 1.8 #### Aug 31, 1993 ####

* The annoying message "can't open file." was due to missing
  terminfo entry for the used terminal. It has now been
  replaced by a hopefully more helpful message.
* Problems with running on serial lines are now fixed.
* Added configuration files for SunOS, Linux, HP/UX, Ultrix,
  386bsd/BSDI (if you have others send'em to me)
* Cleaner Makefile.
* The documentation in manual.doc is now more uptodate.
* update optimization and support for hp terminals, and 386bsd
  console driver(s).
* mvcur optimization for terminals without cursor addressing
  (doesn't work on Linux)
* if cursor moved since last update, getch() will refresh the
  screen before working.
* getch() & alarm() can now live together. in 0.7.3 a signal
  interrupted getch() (bug or feature?) now the getch is
  restarted.
* scanw() et all were sick, now fixed.
* support for 8-bit input (use meta()).
* added default screen size to all terminfos.
* added c++ Ncursesw class.
* several minor bug fixes.

#### ncurses 0.7.2 -> ncurses 0.7.3 #### May 27, 1993 ####

* Config file to cope with different platforms (386BSD, BSDI, Ultrix, SunOS)
* more fixes to lib_getch.c
* changes related to Config

#### ncurses 0.7 -> ncurses 0.7.2 #### May 22, 1993 ####

* docs updated slightly (color usage is now documented).
* yet another fix for getch(), this one fixes problems with ESC being swallowed
  if another character is typed before the 1 second timeout.
* Hopefully, addstr() and addch() are 8-bit clean.
* fixed lib_tparm.c to use stdarg.h (should run on suns now)
* order of capabilities changed to reflect that specified in SYSV
  this will allow for binary-compatibility with existing terminfo dbs.
* added halfdelay()
* fixed problems with asc_init()
* added A_PROTECT and A_INVIS
* cleaned up vidputs()
* general cleanup of the code
* more attention to portability to other systems
* added terminfos for hp70092 (won't work until changes to lib_update.c are
  made) and 386BSD pcvt drivers.

Thanks to Hellmuth Michaelis for his help.
optimization code is slated for the next major release, stay tuned!

#### ncurses 0.6/0.61 -> ncurses 0.7 #### April 1, 1993
Please note that the next release will be called 1.8. If you want to know about
the rationale drop me a line.

Included are several test programs in test/.
I've split up the panels library, reversi, tetris, sokoban. They are now
available separately from netcom.com:pub/zmbenhal/

3) corrected usage of win->_delay value.

4) fixed a bug in lib_getch.c. if it didn't recognize a sequence it would
        simply return the last character in the sequence. The correct
        behavior is to return the entire sequence one character at a time.

#### ncurses0.5 -> ncurses0.6 #### March 1, 1993 ####
* removed _numchngd from struct _win_st and made appropriate changes.
* rewritten kgetch() to remove problems with interaction between alarm and
