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.

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-Han).

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).

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

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

20110220
        + configure script rpath fixes from xterm #269.

20110212
        + regenerated html manpages.
        + use _tracef() in show_where() function of tic, to work correctly with
          special case of trace configuration.

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

          work without requiring the --with-ncurses option.
        + modify test programs to allow them to be built with NetBSD curses.
        + document thick- and double-line symbols in curs_add_wch.3x manpage.
        + document WACS_xxx constants in curs_add_wch.3x manpage.
        + fix some warnings for clang 2.6 "--analyze"
        + modify Ada95 makefiles to make html-documentation with the project
          file configuration if that is used.
        + update config.guess, config.sub

20110108
        + regenerated html manpages.
        + minor fixes to enable lint when trace is not enabled, e.g., with
          clang --analyze.

          R Sedeno).
        + also suppress ncv in konsole-base -TD
        + fixes in wins_nwstr() and related functions to ensure that special
          characters, i.e., control characters are handled properly with the
          wide-character configuration.
        + correct a comparison in wins_nwstr() (Redhat #661506).
        + correct help-messages in some of the test-programs, which still
          referred to quitting with 'q'.

20101204
        + 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

        + fix typo in rmso for tek4106 entry -Goran Weinholt

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

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

          package.

20101023
        + correct parsing of relative tab-stops in tabs program (report by
          Philip Ganchev).
        + adjust configure script so that "t" is not added to library suffix
          when weak-symbols are used, allowing the pthread configuration to
          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

        + fix an unescaped dash in man/tset.1 (report by Sven Joachim).

20101009
        + correct comparison used for setting 16-colors in linux-16color
          entry (Novell #644831) -TD

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

20101002
        + improve linkages in html manpages, adding references to the newer
          pages, e.g., *_variables, curs_sp_funcs, curs_threads.
        + add checks in tic for inconsistent cursor-movement controls, and for
          inconsistent printer-controls.

          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

        + 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.
        + modify configure script to cleanup after check for symbolic links.

20100807
        + correct a typo in mk-1st.awk (patch by Gabriele Balducci)
          (cf: 20100724)
        + improve configure checks for location of tic and infocmp programs
          used for installing database and for generating fallback data,

        + 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.

20100717
        + add hard-reset for rs2 to wsvt25 to help ensure that reset ends
          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.

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.

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

          variable to override (prompted by report by Pablo Cazallas).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

20091114

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

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

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

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

        + document return code from define_key (report by Mike Gran).
        + make some symbolic links in the terminfo directory-tree shorter

          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 20090509 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
          20070704 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).

        + 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 2009031 changes.
        + improve mk-1st.awk script by writing separate cases for the
          LIBTOOL_LINK command, depending on which library (ncurses, ticlib,
          termlib) is to be linked.
        + modify configure.in to allow broken-linker configurations, not just
          enable-reentrant, to set public wrap prefix.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

20081102 5.7 release for upload to ftp.gnu.org

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

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

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

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

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

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

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

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

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

20080907
        + corrected fix for --enable-weak-symbols (report by Frederic L W
          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
          "link_test" builds properly.
        + fix for toe command-line options -u/-U to ensure filename is given.
        + fix allocation-size for command-line parsing in infocmp from 20070728
          (report by Miroslav Lichvar)
        + improve resizeterm() by moving ripped-off lines, and repainting the
          soft-keys (report by Katarina Machalkova)
        + add clarification in wclear's manpage noting that the screen will be
          cleared even if a subwindow is cleared (prompted by Christer Enfors
          question).
        + change test/ncurses.c soft-key tests to work with KEY_RESIZE.

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

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

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

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

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

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

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

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

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

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

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

20070901
        + remove a spurious newline from output of html.m4, which caused links
          for Ada95 html to be incorrect for the files generated using m4.
        + start investigating mutex's for SCREEN manipulation (incomplete).
        + minor cleanup of codes.c/names.c for --enable-const
        + expand/revise "Routine and Argument Names" section of ncurses manpage
          to address report by David Givens in newsgroup discussion.

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).

        + 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_instr.c

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

20070714
        + add test/savescreen.c test-program
        + add check to trace-file open, if the given name is a directory, add
          ".log" to the name and try again.
        + add konsole-256color entry -TD
        + add extra gcc warning options from xterm.

          --disable-echo option is used.
        + modify configure script to disable ada95 if libtool is selected,
          writing a warning message (addresses FreeBSD ports/114493).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

20061217 5.6 release for upload to ftp.gnu.org

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

20051010 5.5 release for upload to ftp.gnu.org

20051008
        + document in demo_forms.c some portability issues.

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

20050924
        + correct header dependencies in progs, allowing parallel make (report
          by Daniel Jacobowitz).
        + modify CF_BUILD_CC to ensure that pre-setting $BUILD_CC overrides
          the configure check for --with-build-cc (report by Daniel Jacobowitz).
        + modify CF_CFG_DEFAULTS to not use /usr as the default prefix for
          NetBSD.
