This is a log of changes that ncurses has gone through since Zeyd started
working with Pavel Curtis' original work, pcurses, in 1992.

Changes through 1.9.9e are recorded by Zeyd M Ben-Halim.
Changes since 1.9.9e are recorded by Thomas E Dickey.

Contributors include those who have provided patches (even small ones), as well
as those who provide useful information (bug reports, analyses).  Changes with
no cited author are the work of Thomas E Dickey (TD).

A few contributors are given in this file by their initials.
They each account for one percent or more of the changes since 1.9.9e.
See the AUTHORS file for the corresponding full names.

Changes through 1.9.9e did not credit all contributions;
it is not possible to add this information.

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.c 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)
        + use button instead of kbuf[0] in EMX-specific part of lib_mouse.c
        + 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
                http://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

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://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
        + updated CF_CURSES_UNCTRL_H and CF_SHARED_OPTS macros from ongoing
          work on cdk.
        + update config.sub from
                http://git.savannah.gnu.org/cgit/config.git

20131110
        + minor cleanup of terminfo.tail

20131102
        + use TS extension to describe xterm's title-escapes -TD
        + modify terminator and nsterm-s to use xterm+sl-twm building block -TD
        + update hurd.ti, add xenl to reflect 2011-03-06 change in
          http://git.savannah.gnu.org/cgit/hurd/hurd.git/log/console/display.c
          (Debian #727119).
        + simplify pfkey expression in ansi.sys -TD

20131027
        + correct/simplify ifdef's for cur_term versus broken-linker and
          reentrant options (report by Jean-Pierre Flori, cf: 20090530).
        + modify release/version combinations in test build-scripts to make
          them more consistent with other packages.

20131019
        + add nc_mingw.h to installed headers for MinGW port; needed for
          compiling ncurses-examples.
        + add rpm-script for testing cross-compile of ncurses-examples.

20131014
        + fix new typo in CF_ADA_INCLUDE_DIRS macro (report by Roumen Petrov).

20131012
        + fix a few compiler warnings in progs and test.
        + minor fix to package/debian-mingw/rules, do not strip dll's.
        + minor fixes to configure script for empty $prefix, e.g., when doing
          cross-compiles to MinGW.
        + add script for building test-packages of binaries cross-compiled to
          MinGW using NSIS.

20131005
        + minor fixes for ncurses-example package and makefile.
        + add scripts for test-builds of cross-compiler packages for ncurses6
          to MinGW.

20130928
        + some build-fixes for ncurses-examples with NetBSD-6.0 curses, though
          it lacks some common functions such as use_env() which is not yet
          addressed.
        + build-fix and some compiler warning fixes for ncurses-examples with
          OpenBSD 5.3
        + fix a possible null-pointer reference in a trace message from newterm.
        + quiet a few warnings from NetBSD 6.0 namespace pollution by
          nonstandard popcount() function in standard strings.h header.
        + ignore g++ 4.2.1 warnings for "-Weffc++" in c++/cursesmain.cc
        + fix a few overlooked places for --enable-string-hacks option.

20130921
        + fix typo in curs_attr.3x (patch by Sven Joachim, cf: 20130831).
        + build-fix for --with-shared option for DragonFly and FreeBSD (report
          by Rong-En Fan, cf: 20130727).

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
          was cached using (report by Kurban Mallachiev).

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.

20130727
        + improve configure macros from ongoing work on cdk, dialog, xterm:
          + 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}
            rather than ${LD} to improve rpath support.
          + CF_SHARED_OPTS - add a symbol to denote the temporary files that
            are created by the macro, to simplify clean-rules.
          + CF_X_ATHENA - trim extra libraries to work with -Wl,--as-needed
        + fix a regression in hashed-database support for NetBSD, which uses
          the key-size differently from other implementations (cf: 20121229).

20130720
        + further improvements for setupterm manpage, clarifying the
          initialization of cur_term.

        + minor compiler-warning fixes

20130706
        + add fallback defs for <inttypes.h> and <stdint.h> (cf: 20120225).
        + add check for size of wchar_t, use that to suppress a chunk of
          wcwidth.h in MinGW port.
        + quiet linker warnings for MinGW cross-compile with dll's using the
          --enable-auto-import flag.

          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
        + remove unnecessary ".ta" in terminfo.tail, add missing ".fi"
          (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
          such as "-5" (patch by Nick Andrik).

20130608
        + 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
          into a user-data structure, keeping the original string for later
          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
          terminal types listed in the preferences dialog -TD

          --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).
        + regenerated html manpages.
        + update doctype used for html documentation.

20130511
        + move nsterm-related entries out of "obsolete" section to more
          plausible "ansi consoles" -TD
        + 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

          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 compatbility 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
        + fix several warnings from clang 3.1 --analyze, includes correcting
          a null-pointer check in _nc_mvcur_resume.
        + correct display of double-width characters with MinGW port (report
          by Erwin Waterlander).
        + replace MinGW's wcrtomb(), fixing a problem with _nc_viscbuf
        > fixes based on Coverity report:
        + correct coloring in test/bs.c
        + correct check for 8-bit value in _nc_insert_ch().
        + remove dead code in progs/tset.c, test/linedata.h
        + add null-pointer checks in lib_tracemse.c, panel.priv.h, and some
          test-programs.

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.
        + correct logic in test/bs.c, when randomly placing a specific type of
          ship.
        + check return value from remove/unlink in tic.
        + check return value from sscanf in test/ncurses.c
        + fix a null dereference in c++/cursesw.cc
        + fix two instances of uninitialized variables when configuring for the
          terminal driver.
        + correct scope of variable used in SetSafeOutcWrapper macro.
        + set umask when calling mkstemp in tic.
        + initialize wbkgrndset() temporary variable when extended-colors are
          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 configure script to show $PATH_SEPARATOR variable.
        + update config.guess, config.sub

20120922
        + 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).

20120211
        + make sgr for xterm-pcolor agree with other caps -TD
        + make sgr for att5425 agree with other caps -TD
        + make sgr for att630 agree with other caps -TD
        + make sgr for linux entries agree with other caps -TD
        + make sgr for tvi9065 agree with other caps -TD
        + make sgr for ncr260vt200an agree with other caps -TD
        + make sgr for ncr160vt100pp agree with other caps -TD
        + make sgr for ncr260vt300an agree with other caps -TD
        + make sgr for aaa-60-dec-rv, aaa+dec agree with other caps -TD
        + 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 prism9 agree with other caps -TD
        + make sgr for icl6404 agree with other caps -TD
        + make sgr for ofcons agree with other caps -TD
        + make sgr for att5410v1, att4415, att620 agree with other caps -TD
        + make sgr for aaa-unk, aaa-rv agree with other caps -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 improvments 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 configuraton.
          + 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.

        + 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:

            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

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

        + modify nc_tparm.h, adding guards against repeated inclusion, and
          allowing TPARM_ARG to be overridden.
        + fix some strict compiler warnings in ncurses library.

        + add special case to _nc_infotocap() to recognize the setaf/setab
          strings from xterm+256color and xterm+88color, and provide a reduced
          version which works with termcap.
        + remove obsolete emacs "Local Variables" section from documentation
          (request by Sven Joachim).
        + update doc/html/index.html to include NCURSES-Programming-HOWTO.html
          (report by Sven Joachim).

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

          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 additonal
          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.
        + modify configure macro CF_LDFLAGS_STATIC to accommodate some loaders
          which do not support selectively linking against static libraries

          gray rather than black like color-0 -TD
        + drop misc/ncu-indent and misc/jpf-indent; they are provided by an
          external package "cindent".

          pages, e.g., *_variables, curs_sp_funcs, curs_threads.
        + add checks in tic for inconsistent cursor-movement controls, and for
          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
        > patch by Juergen Pfeifer:
        + document how to build 32-bit libraries in README.MinGW
        + fixes to filename computation in mk-dlls.sh.in
        + 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 manpages for summarizing public variables of curses-, terminfo-
          and form-libraries.
        + minor fixes to manpages for consistency (patch by Jason McIntyre).
        + modify tic's -I/-C dump to reformat acsc strings into canonical form
          (sorted, unique mapping) (cf: 971004).
        + 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.

        + 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.
        + improved ncu-indent, from mawk changes, allows more than one of
          GCC_NORETURN, GCC_PRINTFLIKE and GCC_SCANFLIKE on a single line.

          the alternate character set (patch by Nicholas Marriott)
        + remove tar-copy.sh and related configure/Makefile chunks, since the
          Ada95 binding is now installed using rules in Ada95/src.

20100703
        + continue integrating changes to use gnatmake project files in Ada95
          + 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.

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.

          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

        + 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

          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

          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

        + 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
        + correct logic in tigetnum(), which caused tput program to treat all
          string capabilities as numeric (report by Rajeev V Pillai,
          cf: 20090711).

20090725
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090718
        + fix a null-pointer check in _nc_format_slks() in lib_slk.c, from
          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
          which is documented in X/Open (cf: 20020427).
        + fixes for test programs to build/work on HPUX and AIX, etc.

20090711
        + 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).

20090627
        + update llib-lncurses[wt] to use sp-funcs.
        + various code-fixes to build/work with --disable-macros configure
          option.
        + add several new files from Juergen Pfeifer which will be used when

          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).

20090523
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090516
        + work around antique BSD game's manipulation of stdscr, etc., versus
          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
        + build fix for _nc_free_and_exit() change in 20090418 (report by
          Christian Ebert).

20090418
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

20090411
        + continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).
          This change finishes merging for menu and panel libraries, does
          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

          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).

          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
          Meunier).

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

        + 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

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).

          is the install-prefix of a given Berkeley Database (prompted by
          pierre4d2 comments).
        + rewrite wrapper for wcrtomb(), making it work on Solaris.  This is

          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).

          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

          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_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

          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().

          (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

        + 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

          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

          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

          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).

          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
