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 Bugzilla
          #310071, patches by Miroslav Lichvar).
        + improve performance of NCURSES_CHAR_EQ code (patch by Miroslav
          Lichvar).
        + update/improve mlterm and rxvt terminfo entries, e.g., for
          the modified cursor- and keypad-keys -TD

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

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

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

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

20070825

          (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

        + 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

          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

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().

        + 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

          (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

        + 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 Bugzilla
          #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 Bugzilla #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 Bugzilla #202480)).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

20051010 5.5 release for upload to ftp.gnu.org

20051008
        + document in demo_forms.c some portability issues.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

20050108
        + merge some development changes to extend color capabilities.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

20020817
        + modify lib_screen.c and lib_newwin.c to maintain the SCREEN-specific
          pointers for curscr/stdscr/newscr when scr_save() and scr_restore()
          modify the global curscr/stdscr/newscr variables.  Fixes Redhat
          bugzilla #68199 dated 2002-07-07.
        + add checks for null pointer in calls to tparm() and tgoto() based on
          FreeBSD bug report.  If ncurses were built with termcap support, and
          the first call to tgoto() were a zero-length string, the result would
          be a null pointer, which was not handled properly.
        + correct a typo in terminfo.head, which gave the octal code for colon
          rather than comma.
        + remove the "tic -u" option from 20020810, since it did not account
          for nested "tc=" clauses, and when that was addressed, was still
          unsatisfactory.

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

20020803
        + fix an off-by-one in lib_pad.c check for limits of pad (patch by
          Philippe Blain).
        + revise logic for BeOS in lib_twait.c altered in 20011013 to restore
          logic used by lib_getch.c's support for GPM or EMX mouse (report by
          Philippe Blain)
        + remove NCURSES_CONST from several prototypes in curses.wide, to make
          the --enable-const --enable-widec configure options to work together
          (report by George Goffe <grgoffe@yahoo.com>).

20020727
        + finish no-leak checking in cardfile.c, using this for testing changes
          to resizeterm().
        + simplify _nc_freeall() using delscreen().

20020720
        + check error-return from _nc_set_tty_mode() in _nc_initscr() and
          reset_prog_mode() (report/patch by Philippe Blain).
        + regenerate configure using patch for autoconf 2.52, to address
          problem with identifying C++ bool type.
        + correct/improve logic to produce an exit status for errors in tput,
          which did not exit with an error when told to put a string not in the
          current terminfo entry (report by David Gomez <david@pleyades.net>).
        + modify configure script AC_OUTPUT() call to work around defect in
          autoconf 2.52 which adds an ifdef'd include to the generated
          configure definitions.
        + remove fstat() check from scr_init(), which also fixes a missing
          include for <sys/stat.h> from 20020713 (reported by David Ellement,
          fix suggested by Philippe Blain).
        + update curs_scanw.3x manpage to note that XSI curses differs from
          SVr4 curses: return-values are incompatible.
        + correct several prototypes in manpages which used const
          inconsistently with the curses.h file, and removed spurious const's
          in a few places from curses.h, e.g., for wbkgd() (report by Glenn
          Maynard <glenn@zewt.org>).
        + change internal type used by tparm() to long, to work with LP64 model.
        + modify nc_alloc.h to allow building with g++, for testing.

20020713
        + add resize-handling to cardfile.c test program.
        + altered resizeterm() to avoid having it fail when a child window
          cannot be resized because it would be larger than its parent.  (More
          work must be done on this, but it works well enough to integrate).
        + improve a limit-check in lib_refresh.c
        + remove check in lib_screen.c relating dumptime to file's modification
          times, since that would not necessarily work for remotely mounted
          filesystems.
        + modify lrtest to simplify debugging changes to resizeterm, e.g.,
          t/T commands to enable/disable tracing.
        + updated status of multibyte support in TO-DO.
        + update contact info in source-files (patch by Juergen Pfeifer).

20020706
        + add Caps.hpux11, as an example.
        + modify version_filter(), used to implement -R option for tic and
          infocmp, to use computed array offsets based on the Caps.* file which
          is actually configured, rather than constants which correspond to
          the Caps file.
        + reorganized lib_raw.c to avoid updating SP and cur_term state if the
          functions fail (reported by Philippe Blain).
        + add -Wundef to gcc warnings, adjust a few ifdef's to accommodate gcc.

20020629
        + correct parameters to setcchar() in ncurses.c (cf: 20020406).
        + set locale in most test programs (view.c and ncurses.c were the
          only ones).
        + add configure option --with-build-cppflags (report by Maksim A
          Nikulin <M.A.Nikulin@inp.nsk.su>).
        + correct a typo in wide-character logic for lib_bkgnd.c (Philippe
          Blain).
        + modify lib_wacs.c to not cancel the acsc, smacs, rmacs strings when
          in UTF-8 locale.  Wide-character functions use Unicode values, while
          narrow-character functions use the terminfo data.
        + fix a couple of places in Ada95/samples which did not compile with
          gnat 3.14
        + modify mkinstalldirs so the DOS-pathname case is locale-independent.
        + fix locale problem in MKlib_gen.sh by forcing related variables to
          POSIX (C), using same approach as autoconf (set variables only if
          they were set before).  Update MKterminfo.sh and MKtermsort.sh to
          match.

20020622
        + add charset to generated html.
        + add mvterm entry, adapted from a FreeBSD bug-report by Daniel Rudy
          <dcrudy@pacbell.net> -TD
        + add rxvt-16color, ibm+16color entries -TD
        + modify check in --disable-overwrite option so that it is used by
          default unless the --prefix/$prefix value is not /usr, in attempt to
          work around packagers, e.g., for Sun's freeware, who do not read the
          INSTALL notes.

20020615
        + modify wgetch() to allow returning ungetch'd KEY_RESIZE as a function
          key code in get_wch().
        + extended resize-handling in test/ncurses 'a' menu to the entire
          stack of windows created with 'w' commands.
        + improve $COLORFGBG feature by interpreting an out-of-range color
          value as an SGR 39 or 49, for foreground/background respectively.
        + correct a typo in configure --enable-colorfgbg option, and move it
          to the experimental section (cf: 20011208).

20020601
        + add logic to dump_entry.c to remove function-key definitions that do
          not fit into the 1023-byte limit for generated termcaps.  This makes
          hds200 fit.
        + more improvements to tic's warnings, including logic to ignore
          differences between delay values in sgr strings.
        + move definition of KEY_RESIZE into MKkeydefs.sh script, to
          accommodate Caps.osf1r5 which introduced a conflicting definition.

20020525
        + add simple resize-handling in test/ncurses.c 'a' menu.
        + fixes in keyname() and _tracechar() to handle negative values.
        + make tic's warnings about mismatches in sgr strings easier to follow.
        + correct tic checks for number of parameters in smgbp and smglp.
        + improve scoansi terminfo entry, and add scoansi-new entry -TD
        + add pcvt25-color terminfo entry -TD
        + add kf13-kf48 strings to cons25w terminfo entry (reported by Stephen
          Hurd <deuce@lordlegacy.org> in newsgroup lucky.freebsd.bugs) -TD
        + add entrypoint _nc_trace_ttymode(), use this to distinguish the
          Ottyb and Nttyb members of terminal (aka cur_term), for tracing.

20020523
        + correct and simplify logic for lib_pad.c change in 20020518 (reported
          by Mike Castle).

20020518
        + fix lib_pad.c for case of drawing a double-width character which
          falls off the left margin of the pad (patch by Kriang Lerdsuwanakij
          <lerdsuwa@users.sourceforge.net>)
        + modify configure script to work around broken gcc 3.1 "--version"
          option, which adds unnecessary trash to the requested information.
        + adjust ifdef's in case SIGWINCH is not defined, e.g., with DJGPP
          (reported by Ben Decker <deckerben@freenet.de>).

20020511
        + implement vid_puts(), vid_attr(), term_attrs() based on the narrow-
          character versions as well.
        + implement erasewchar(), killwchar() based on erasechar() and
          killchar().
        + modify erasechar() and killchar() to return ERR if the value was
          VDISABLE.
        + correct a bug in wresize() in handling subwindows (based on patch by
          Roger Gammans <rgammans@computer-surgery.co.uk>, report by Scott Beck
          <scott@gossamer-threads.com>).
        + improve test/tclock.c by making the second-hand update more often
          if gettimeofday() is available.

20020429
        + workaround for Solaris sed with MKlib_gen.sh (reported by Andy
          Tsouladze <andyt@mypoints.com>).

20020427
        + correct return-value from getcchar(), making it consistent with
          Solaris and Tru64.
        + reorder loops that generate makefile rules for different models vs
          subsets so configure --with-termlib works again.  This was broken by
          logic added to avoid duplicate rules in changes to accommodate cygwin
          dll's (reported by George.R.Goffe@seagate.com).
        + update config.guess, config.sub

20020421
        + modify ifdef's in write_entry.c to allow use of symbolic links on
          platforms with no hard links, e.g., BeOS.
        + modify a few includes to allow compile with BeOS, which has stdbool.h
          with a conflicting definition for 'bool' versus its OS.h definition.
        + amend MKlib_gen.sh to work with gawk, which defines 'func' as an
          alias for 'function'.

20020420
        + correct form of prototype for ripoffline().
        + modify MKlib_gen.sh to test that all functions marked as implemented
          can be linked.

20020413
        + add manpages: curs_get_wstr.3x, curs_in_wchstr.3x
        + implement wgetn_wstr().
        + implement win_wchnstr().
        + remove redefinition of unget_wch() in lib_gen.c (reported by
          Jungshik Shin <jshin@jtan.com>).

20020406
        + modified several of the test programs to allow them to compile with
          vendor curses implementations, e.g., Solaris, AIX -TD

20020323
        + modified test/configure to allow configuring against ncursesw.
        + change WACS_xxx definition to use address, to work like Tru64 curses.

20020317
        + add 'e' and 'm' toggles to 'a', 'A' tests in ncurses.c to demonstrate
          effect of echo/noecho and meta modes.
        + add 'A' test to ncurses.c to demonstrate wget_wch() and related
          functions.
        + add manpage: curs_get_wch.3x
        + implement unget_wch().
        + implement wget_wch().

20020310
        + regenerated html manpages.
        + add manpages: curs_in_wch.3x, curs_ins_wch.3x, curs_ins_wstr.3x
        + implement wins_wch().
        + implement win_wch().
        + implement wins_nwstr(), wins_wstr().

20020309
        + add manpages: curs_addwstr.3x, curs_winwstr.3x
        + implement winnwstr(), winwstr().

20020223
        + add manpages: curs_add_wchstr.3x, curs_bkgrnd.3x
        + document wunctrl, key_name.
        + implement key_name().
        + remove const's in lib_box.c incorrectly leftover after splitting off
          lib_box_set.c
        + update llib-lncurses, llib-ncursesw, fix configure script related to
          these.

20020218
        + remove quotes on "SYNOPSIS" in man/curs_box_set.3x, which resulted
          in spurious symlinks on install.

20020216
        + implement whline_set(), wvline_set(), add manpage curs_border_set.
        + add subtest 'b' to 'F' and 'f' in ncurses.c to demonstrate use of
          box() and box_set() functions.
        + add subtest 'u' to 'F' in ncurses.c, to demonstrate use of addstr()
          given UTF-8 string equivalents of WACS_xxx symbols.
        + minor fixes to several manpages based on groff -ww output.
        + add descriptions of external variables of termcap interface to
          the manpage (report by Bruce Evans <bde@zeta.org.au>).
        > patches by Bernhard Rosenkraenzer:
        + correct configure option --with-bool, which was executed as
          --with-ospeed.
        + add quotes for parameters of --with-bool and --with-ospeed configure
          options.
        > patch by Sven Verdoolaege (report by Gerhard Haering
          <haering_linux@gmx.de>):
        + correct typos in definitions of several wide-character macros:
          waddwstr, wgetbkgrnd, mvaddwstr, mvwadd_wchnstr, mvwadd_wchnstr,
          mvwaddwstr.
        + pass $(CPPFLAGS) to MKlib_gen.sh, thereby fixing a missing definition
          of _XOPEN_SOURCE_EXTENDED, e.g., on Solaris

20020209
        + implement wide-acs characters for UTF-8 locales.  When in UTF-8
          locale, ignore narrow version of acs.  Add 'F' test to test/ncurses.c
          to demonstrate.
        + correct prototype in keybound manpage (noted from a Debian mailing
          list item).

20020202
        + add several cases to the wscanw() example in testcurs.c, showing the
          format.
        + implement a simple vsscanf() fallback function which uses the %n
          conversion to help parse the input data (prompted by discussion with
          Albert Chin-A-Young).
        + modify mk-1st.awk and test/Makefile.in to add $(LDFLAGS) when making
          shared libraries, and to use $(CFLAGS) when linking test programs
          (patch by Albert Chin-A-Young).
        + add a call to _nc_keypad() in keypad() to accommodate applications
          such as nvi, which use curses for output but not for input (fixes
          Debian #131263, cf: 20011215).
        + add entrypoints to resizeterm.c which provide better control over the
          process:  is_term_resized() and resize_term().  The latter restores
          the original design of resizeterm() before KEY_RESIZE was added in
          970906.  Do this to accommodate 20010922 changes to view.c, but allow
          for programs with their own sigwinch handler, such as lynx (reported
          by Russell Ruby <russ@math.orst.edu>).

20020127
        + fix a typo in change to mk-1st.awk, which broke the shared-library
          makefile rules (reported by Martin Mokrejs).

20020126
        + update config.guess, config.sub
        + finish changes needed to build dll's on cygwin.
        + fix a typo in mvwchat() macro (reported by Cy <yam@homerow.net).

20020119
        + add case in lib_baudrate.c for B921600 (patch by Andrey A Chernov).
        + correct missing sed-editing stage in manpage installs which is used
          to rename manpages, broken in 20010324 fix for Debian #89939 (Debian
          #78866).
        + remove -L$(libdir) from linker flags, probably not needed any more
          since HPUX is handled properly (reported by Niibe Yutaka
          <gniibe@m17n.org>).
        + add configure check for mbstate_t, needed for wide-character
          configuration.  On some platforms we must include <wchar.h> to
          define this (reported by Daniel Jacobowitz).
        + incorporate some of the changes needed to build dll's on cygwin.

20020112a
        + workaround for awk did not work with mawk, adjusted shell script.

20020112
        + add Caps.osf1r5, as an example.
        + modify behavior of can_clear_with() so that if an application is
          running in a non-bce terminals with default colors enabled, it
          returns true, allowing the user to select/paste text without picking
          up extraneous trailing blanks (adapted from patch by Daniel
          Jacobowitz <dmj+@andrew.cmu.edu>).
        + modify generated curses.h to ifdef-out prototypes for extensions if
          they are disabled, and to define curses_version() as a string in that
          case.  This is needed to make the programs such as tic build in that
          configuration.
        + modified generated headers.sh to remove a gzip'd version of the
          target file if it exists, in case non-gzip'd manpages are installed
          into a directory where gzip'd ones exist.  In that case, the latter
          would be found.
        + corrected a redundant initialization of signal handlers from 20010922
          changes.
        + clarified bug-reporting address in terminfo.src (report by John H
          DuBois III <spcecdt@armory.com>).
        > several fixes from Robert Joop:
        + do not use "-v" option of awk in MKkey_defs.sh because it does not
          work with SunOS nawk.
        + modify definitions for libutf8 in curses.h to avoid redefinition
          warnings for mblen
        + quoted references to compiler in shell command in misc/Makefile, in
          case it uses multiple tokens.

20011229
        + restore special case from 20010922 changes to omit SA_RESTART when
          setting up SIGWINCH handler, which is needed to allow wgetch() to be
          interrupted by that signal.
        + update configure macro CF_WITH_PATHLIST, to omit some double quotes
          not needed with autoconf 2.52
        + revert configure script to autoconf 2.13 patched with
                autoconf-2.13-19990117.patch.gz (or later)
          from
                ftp://invisible-island.net/autoconf/
          because autoconf 2.52 macro AC_PROG_AWK does not work on HPUX 11.0
          (report by David Ellement <ellement@sdd.hp.com>).  This also fixes a
          different problem configuring with Mac OS X (reported by Marc Smith
          <marc.a.smith@home.com>).

20011222
        + modify include/edit_cfg.h to eliminate BROKEN_LINKER symbol from
          term.h
        + move prototype for _nc_vsscanf() into curses.h.in to omit
          HAVE_VSSCANF symbol from curses.h, which was dependent upon the
          ncurses_cfg.h file which is not installed.
        + use ACS_LEN rather than SIZEOF(acs_map) in trace code of lib_acs.c,
          to work with broken linker configuration, e.g., cygwin (report by
          Robert Joop <rj@rainbow.in-berlin.de>).
        + make napms() call _nc_timed_wait() rather than poll() or select(),
          to work around broken implementations of these on cygwin.

20011218
        + drop configure macro CF_WIDEC_SHIFT, since that was rendered obsolete
          by Sven Verdoolaege's rewrite of wide-character support.  This makes
          libncursesw incompatible again, but makes the header files almost the
          same as in the narrow-character configuration.
        + simplify definitions that combine wide/narrow versions of bkgd, etc.,
          to eliminate differences between the wide/narrow versions of curses.h
        + correct typo in configure macro CF_FUNC_VSSCANF
        + correct location of call to _nc_keypad() from 20011215 changes which
          prevented keypad() from being disabled (reported by Lars Hecking).

20011215
        + rewrote ncurses 'a' test to exercise wgetch() and keypad() functions
          better, e.g., by adding a 'w' command to create new windows which
          may have different keypad() settings.
        + corrected logic of keypad() by adding internal screen state to track
          whether the terminal's keypad-mode has been set.  Use this in
          wgetch() to update the keypad-mode according to whether the
          associated window's keypad-mode has been set with keypad().  This
          corrects a related problem restoring terminal state after handling
          SIGTSTP (reported by Mike Castle).
        + regenerate configure using patch for autoconf 2.52
                autoconf-2.52-patch.gz
          at
                ftp://invisible-island.net/autoconf/
        + update config.guess, config.sub from
                http://subversions.gnu.org/cgi-bin/viewcvs/config/config/
        + minor changes to quoting in configure script to allow it to work
          with autoconf 2.52

20011208
        + modify final checks in lib_setup.c for line and col values, making
          them independent.
        + modify acs_map[] if configure --broken-linker is specified, to make
          it use a function rather than an array (prompted by an incorrect
          implementation in cygwin package).
        + correct spelling of configure option --enable-colorfgbg, which
          happened to work if --with-develop was set (noted in cygwin package
          for ncurses).
        + modify ifdef for genericerror() to compile with SUNWspro Sun WorkShop
          6 update 1 C++ 5.2 (patch by Sullivan N Beck <sbeck@cise.ufl.edu>).
        + add configure checks to see if ncurses' fallback vsscanf() will
          compile either of the special cases for FILE structs, and if not,
          force it to the case which simply returns an error (report by
          Sullivan N Beck <sbeck@cise.ufl.edu> indicates that Solaris 8 with
          64-bits does not allow access to FILE's fields).
        + modify ifdef's for c++/cursesw.cc to use the fallback vsscanf() in
          the ncurses library if no better substitute for this can be found
          in the C++ runtime.
        + modify the build to name dynamic libraries according to the
          convention used on OS X and Darwin.  Rather than something like
          libncurses.dylib.5.2, Darwin would name it libncurses.  5.dylib.
          There are a few additional minor fixes, such as setting the library
          version and compatibility version numbers (patch by Jason Evans
          <jevans@apple.com>).
        + use 'sh' to run mkinstalldirs, to work around problems with buggy
          versions of 'make' on OS/2 (report by John Polterak <jp@eyup.org>).
        + correct typo in manpage description of curs_set() (Debian #121548).
        + replace the configure script existence-check for mkstemp() by one
          that checks if the function works, needed for older glibc and
          AmigaOS.

20011201
        + modify script that generates fallbacks.c to compile a temporary
          copy of the terminfo source in case the host does not contain all of
          the entries requested for fallbacks (request by Greg Roelofs).
        + modify configure script to accommodate systems such as Mac OS X whose
          <stdbool.h> header defines a 'bool' type inconsistent with ncurses,
          which normally makes 'bool' consistent with C++.  Include <stdbool.h>
          from curses.h to force consistent usage, define a new type
          NCURSES_BOOL and related that to the exported 'bool' as either a
          typedef or definition, according to whether <stdbool.h> is present
          (based on a bug report for tin 1.5.9 by Aaron Adams <adamsa@mac.com>).

20011124
        + added/updated terminfo entries for M$ telnet and KDE konsole -TD

20011117
        + updated/expanded Apple_Terminal and Darwin PowerPC terminfo entries
          (Benjamin C W Sittler).
        + add putty terminfo entry -TD
        + if configuring for wide-curses, define _XOPEN_SOURCE_EXTENDED, since
          this may not otherwise be defined to make test/view.c compile.

20011110
        + review/correct several missing/generated items in curses.wide, sorted
          the lists to make subsequent diff's easier to track.

20011103
        + add manual pages for add_wch(), echo_wchar(), getcchar(),
          mvadd_wch(), mvwadd_wch(), setcchar(), wadd_wch() and wecho_wchar().
        + implement wecho_wchar()
        + modify _tracedump() to handle wide-characters by mapping them to '?'
          and control-characters to '.', to make the trace file readable.  Also
          dynamically allocate the buffer used by _tracedump() for formatting
          the results.
        + modify T_CALLED/T_RETURN macros to ease balancing call/return lines
          in a trace by using curly braces.
        + implement _nc_viscbuf(), for tracing cchar_t arrays.
        + correct trace-calls in setcchar() and getcchar() functions, which
          traced the return values but not the entry to each function.
        + correct usage message in test/view.c, which still mentioned -u flag.

20011027
        + modify configure script to allow building with termcap only, or with
          fallbacks only.  In this case, we do not build tic and toe.
        + add configure --with-termpath option, to override default TERMPATH
          value of /etc/termcap:/usr/share/misc/termcap.
        + cosmetic change to tack: make menu descriptions agree with menu
          titles.

20011020
        + rewrote limit-checks in wscrl() and associated _nc_scroll_window(),
          to ensure that if the parameter of wscrl() is larger than the size of
          the scrolling region, then the scrolling region will be cleared
          (report by Ben Kohlen <bckohlen@yahoo.com>).
        + add trace/varargs.c, using this to trace parameters in lib_printw.c
        + implement _tracecchar_t2() and _tracecchar_t().
        + split-out trace/visbuf.c
        + correct typo in lib_printw.c changes from 20010922 (report by Mike
          Castle).

20011013
        + modify run_tic.sh to check if the build is a cross-compile.  In that
          case, do not use the build's tic to install the terminfo database
          (report by Rafael Rodriguez Velilla <rrv@tid.es>).
        + modify mouse click resolution so that mouseinterval(-1) will disable
          it, e.g., to handle touchscreens via a slow connection (request by
          Byron Stanoszek <gandalf@winds.org>).
        + correct mouseinterval() default value shown in curs_mouse.3x
        + remove conflicting definition of mouse_trafo() (reported by Lars
          Hecking, using gcc 2.95.3).

20011001
        + simpler fix for signal_name(), to replace the one overlooked in
          20010929 (reported by Larry Virden).

20010929
        + add -i option to view.c, to test ncurses' check for non-default
          signal handler for SIGINT, etc.
        + add cases for shared-libraries on Darwin/OS X (patch by Rob Braun
          <bbraun@synack.net>).
        + modify tset to restore original I/O modes if an error is encountered.
          Also modify to use buffered stderr consistently rather than mixing
          with write().
        + change signal_name() function to use if-then-else rather than case
          statement, since signal-values aren't really integers (reported by
          Larry Virden).
        + add limit checks in wredrawln(), fixing a problem where lynx was
          repainting a pad which was much larger than the screen.

20010922
        + fix:  PutRange() was counting the second part of a wide character as
          part of a run, resulting in a cursor position that was one too far
          (patch by Sven Verdoolaege).
        + modify resizeterm() to not queue a KEY_RESIZE if there was no
          SIGWINCH, thereby separating the two styles of SIGWINCH handling
          in test/view.c
        + simplified lib_tstp.c, modify it to use SA_RESTART flag for SIGWINCH.
        + eliminate several static buffers in the terminfo compiler, using
          allocated buffers.
        + modify MKkeyname.awk so that keyname() does not store its result into
          a static buffer that is overwritten by the next call.
        + reorganize the output of infocmp -E and -e options to compile cleanly
          with gcc -Wwrite-strings warnings.
        + remove redefinition of chgat/wchgat/mvwchgat from curses.wide

20010915
        + add label to test/view.c, showing the name of the last key or signal
          that made the screen repaint, to make it clearer when a sigwinch
          does this.
        + use ExitProgram() consistently in the test-programs to make it
          simpler to test leaks with dmalloc, etc.
        + move hashtab static data out of hashmap.c into SCREEN struct.
        + make NO_LEAK code compile with revised WINDOWLIST structs.

20010908
        + modify tgetent() to check if exit_attribute_mode resets the alternate
          character set, and if so, attempt to adjust the copy of the termcap
          "me" string which it will return to eliminate that part.  In
          particular, 'screen' would lose track of line-drawing characters
          (report by Frederic L W Meunier <0@pervalidus.net>, analysis by
          Michael Schroeder).

20010901
        + specify DOCTYPE in html manpages.
        + add missing macros for several "generated" functions:  attr_get(),
          attr_off(), attr_on(), attr_set(), chgat(), mvchgat(), mvwchgat() and
          mouse_trafo().
        + modify view.c to agree with non-experimental status of ncurses'
          sigwinch handler:
          + change the sense of the -r option, making it default to ncurses'
            sigwinch handler.
          + add a note explaining what functions are unsafe in a signal
            handler.
          + add a -c option, to set color display, for testing.
        + unset $data variable in MKterminfo.sh script, to address potential
          infinite loop if shell malfunction (report by Samuel Mikes
          <smikes@cubane.com>, for bash 2.05.0 on a Linux 2.0.36 system).
        + change kbs in mach terminfo entries to ^?  (Marcus Brinkmann
          <Marcus.Brinkmann@ruhr-uni-bochum.de>).
        + correct logic for COLORFGBG environment variable: if rxvt is compiled
          with xpm support, the variable has three fields, making it slightly
          incompatible with itself.  In either case, the background color is
          the last field.

20010825
        + move calls to def_shell_mode() and def_prog_mode() before loop with
          callbacks in lib_set_term.c, since the c++ demo otherwise initialized
          the tty modes before saving them (patch by John David Anglin
          <dave@hiauly1.hia.nrc.ca>).
        + duplicate logic used to initialize trace in newterm(), in initscr()
          to avoid confusing trace of initscr().
        + simplify allocation of WINDOW and WINDOWLIST structs by making the
          first a part of the second rather than storing a pointer.  This saves
          a call to malloc for each window (discussion with Philippe Blain).
        + remove unused variable 'used_ncv' from lib_vidattr.c (Philippe
          Blain).
        + modify c++/Makefile.in to accommodate archive programs that are
          different for C++ than for C, and add cases for vendor's C++
          compilers on Solaris and IRIX (report by Albert Chin-A-Young).
        + correct manpage description of criteria for deciding if the terminal
          supports xterm mouse controls.
        + add several configure script options to aid with cross-compiling:
          --with-build-cc, --with-build-cflags, --with-build-ldflags, and
          --with-build-libs (request by Greg Roelofs).
        + change criteria for deciding if configure is cross-compiling from
          host/build mismatch to host/target mismatch (request by Greg Roelofs
          <greg.roelofs@philips.com>).
        + correct logic for infocmp -e and -E options which writes the data for
          the ext_Names[] array.  This is needed if one constructs a fallback
          table for a terminfo entry which uses extended termcap names, e.g.,
          AX in a color xterm.
        + fix undefined NCURSES_PATHSEP when configure --disable-database
          option is given.

20010811
        + fix for VALID_BOOLEAN() macro when char is not signed.
        + modify 'clean' rule for C++ binding to work with Sun compiler, which
          caches additional information in a subdirectory of the objects.
        + added llib-ncursesw.

20010804
        + add Caps.keys example for experimental extended function keys
          (adapted from a patch by Ilya Zakharevich).
        + correct parameter types of vidputs() and vidattr() to agree with
          header files (report by William P Setzer).
        + fix typos in several man-pages (patch by William P Setzer).
        + remove unneeded ifdef for __GNUG__ in CF_CPP_VSCAN_FUNC configure
          macro, which made ncurses C++ binding fail to build with other
          C++ compilers such as HPUX 11.x (report by Albert Chin-A-Young).
        + workaround for bug in HPUX 11.x C compiler: add a blank after
          NCURSES_EXPORT macro in form.h (report by Albert Chin-A-Young)
        + ignore blank lines in Caps* files in MKkey_defs.sh script (report by
          Albert Chin-A-Young).
        + correct definition of key_end in Caps.aix4, which left KEY_END
          undefined (report by Albert Chin-A-Young).
        + remove a QNX-specific fallback prototype for vsscanf(), which is
          obsolete with QNX RTP.
        + review/fix some of the T() and TR() macro calls, having noticed that
          there was no data for delwin() in a trace of dialog because there was
          no returnVoid call for wtimeout().  Also, traces in lib_twait.c are
          now selected under TRACE_IEVENT rather than TRACE_CALLS.

20010728
        + add a _nc_access() check before opening files listed via $TERMPATH.
        + using modified man2html, regenerate some of the html manpages to fix
          broken HREF's where the link was hyphenated.

20010721
        + add some limit/pointer checks to -S option of tputs.
        + updated/expanded Apple_Terminal and Darwin PowerPC terminfo entries
          (Benjamin C W Sittler).
        + add a note in curs_termcap.3x regarding a defect in the XSI
          description of tgetent (based on a discussion with Urs Jansen
          regarding the HPUX 11.x implementation, whose termcap interface is
          not compatible with existing termcap programs).
        + modify manhtml rule in dist.mk to preserve copyright notice on the
          generated files, as well as to address HTML style issues reported by
          tidy and weblint.  Regenerated/updated corresponding html files.
        + comment out use of Protected_Character and related rarely used
          attributes in ncurses Ada95 test/demo to compile with wide-character
          configuration.

20010714
        + implement a simple example in C++ demo to test scanw().
        + corrected stdio function used to implement scanw() in cursesw.cc
        + correct definition of RemAttr() macro from 20010602 changes, which
          caused C++ SillyDemo to not show line-drawing characters.
        + modify C++ binding, adding getKey() which can be overridden by user
          to substitute functions other than getch() for keyboard processing
          of forms and menus (patch by Juergen Pfeifer).

20010707
        + fix some of the trace calls which needed modification to work with
          new wide-character structures.
        + modify magic-cookie code in tty_update.c to compile with new
          wide-character structures (report by <George.R.Goffe@seagate.com>).
        + ensure that _XOPEN_SOURCE_EXTENDED is defined in curses.priv.h if
          compiling for wide-character configuration.
        + make addwnstr() handle non-spacing characters (patch by Sven
          Verdoolaege).

20010630
        + add configure check to define _GNU_SOURCE, needed to prop up glibc
          header files.
        + split-out include/curses.wide to solve spurious redefinitions caused
          by defining _GNU_SOURCE, and move includes for <signal.h> before
          <curses.h> to work around misdefinition of ERR in glibc 2.1.3 header
          file.
        + extended ospeed change to NetBSD and OpenBSD -TD
        + modify logic in lib_baudrate.c for ospeed, for FreeBSD to make it
          work properly for termcap applications (patch by Andrey A Chernov).

20010623
        + correct an overlooked CharOf/UChar instance (reports by Eugene Lee
          <eugene@anime.net>, Sven Verdoolaege).
        + correct unneeded ifdef for wunctrl() (reported by Sven Verdoolaege)

20010618
        + change overlooked several CharOf/UChar instances.
        > several patches from Sven Verdoolaege:
        + correct a typo in wunctrl(), which made it appear that botwc() was
          needed (no such function: use btowc()).
        + reimplement wide-character demo in test/view.c, using new functions.
        + implement getcchar(), setcchar(), wadd_wchnstr() and related macros.
        + fix a syntax problem with do/if/while in PUTC macro (curses.priv.h).

20010616
        + add parentheses in macros for malloc in test.priv.h, fixes an
          expression in view.c (report by Wolfgang Gutjahr <gutw@knapp.co.at>).
        + add Caps.uwin, as an example.
        + change the way curses.h is generated, making the list of function
          key definitions extracted from the Caps file.
        + add #undef's before possible redefinition of ERR and OK in curses.h
        + modify logic in tic, toe, tput and tset which checks for basename of
          argv[0] to work properly on systems such as OS/2 which have
          case-independent filenames and/or program suffixes, e.g., ".ext".

20010609
        + add a configure check, if --enable-widec is specified, for putwc(),
          which may be in libutf8.
        + remove some unnecessary text from curs_extend.3x and
          default_colors.3x which caused man-db to make incorrect symbolic
          links (Debian bug report #99550).
        + add configure check if cast for _IO_va_list is needed to compile
          C++ vscan code (Debian bug report #97945).
        > several patches from Sven Verdoolaege:
        + correct code that used non-standard auto-initialization of a struct,
          which gcc allows (report by Larry Virden).
        + use putwc() in PUTC() macro.
        + make addstr() work for the special case where the codeset is
          non-stateful (eg. UTF-8), as well as stateful codesets.

20010603
        + correct loop expression in NEXT_CHAR macro for lib_addstr.c changes
          from 20010602 (report by Mike Castle).

20010602
        + modify mvcur() to avoid emitting newline characters when nonl() mode
          is set.  Normally this is not a problem since the actual terminal
          mode is set to suppress nl/crlf translations, however it is useful to
          allow the caller to manipulate the terminal mode to avoid staircasing
          effects after spawning a process which writes messages (for lynx
          2.8.4) -TD
        > several patches from Sven Verdoolaege <skimo@kotnet.org>:
        + remove redundant type-conversion in fifo_push()
        + correct definition of addwstr() macro in curses.h.in
        + remove _nc_utf8_outch()
        + rename most existing uses of CharOf() to UChar(), e.g., where it is
          used to prevent sign-extension in ctype macros.
        + change some chtype's to attr_t's where the corresponding variables
          are used to manipulate attributes.
        + UpdateAttr() was applied to both attributes (attr_t) and characters
          (chtype).  Modify macro and calls to it to make these distinct.
        + add CharEq() macro, use in places where wide-character configuration
          implementation uses a struct for cchar_t.
        + moved struct ldat into curses.priv.h, to hide implementation details.
        + change CharOf() macro to use it for masking A_CHARTEXT data from
          chtype's.
        + add L() macro to curses.priv.h, for long-character literals.
        + replace several assignments from struct ldat entries to chtype or
          char values with combinations of CharOf() and AttrOf() macros.
        + add/use intermediate ChAttrOf() and ChCharOf() macros where we know
          we are using chtype data.
        + add/use lowlevel attribute manipulation macros AddAttr(), RemAttr()
          and SetAttr().
        + add/use SetChar() macro, to change a cchar_t based on a character and
          attributes.
        + convert most internal use of chtype to NCURSES_CH_T, to simplify use
          of cchar_t for wide-character configuration.  Similarly, use ARG_CH_T
          where a pointer would be more useful.
        + add stubs for tracing cchar_t values.
        + add/use macro ISBLANK()
        + add/use constructors for cchar_t's: NewChar(), NewChar2().
        + add/use macros CHREF(), CHDEREF(), AttrOfD(), CharOfD() to facilitate
          passing cchar_t's by address.
        + add/use PUTC_DATA, PUTC() macros.
        + for wide-character configuration, move the window background data to
          the end of the WINDOW struct so that whether _XOPEN_SOURCE_EXTENDED
          is defined or not, the offsets in the struct will not change.
        + modify addch() to work with wide-characters.
        + mark several wide-character functions as generated in curses.h.in
        + implement wunctrl(), wadd_wch(), wbkgrndset(), wbkgrnd(),
          wborder_set() and waddnwstr().

20010526
        + add experimental --with-caps=XXX option to customize to similar
          terminfo database formats such as AIX 4.x
        + add Caps.aix4 as an example.
        + modify Caps to add columns for the the KEY_xxx symbols.
        + modify configure --with-widec to suppress overwrite of libcurses.so
          and curses.h
        + add checks to toe.c to avoid being confused by files and directories
          where we would expect the reverse, e.g., source-files in the
          top-level terminfo levels as is the case for AIX.

20010519
        + add top-level 'depend' rule for the C sources, assuming that the
          makedepend program is available.  As a side-effect, this makes
          the generated sources, as in "make sources" (prompted by a report
          by Mike Castle that "make -j" fails because the resulting parallel
          processes race to generate ncurses/names.c).
        + modify configure script so that --disable-overwrite option's action
          to add a symbolic link for libcurses applies to the static library as
          well as the shared library when both are configured (report by Felix
          Natter <f.natter@ndh.net>).
        + add ELKS terminfo entries (Federico Bianchi
          <bianchi@www.arte.unipi.it>)
        + add u6 (CSR) to Eterm (Michael Jennings).

20010512
        + modify test/ncurses.c to work with xterm-256color, which has fewer
          color pairs than colors*colors (report by David Ellement
          <ellement@sdd.hp.com>).

20010505
        + corrected screen.xterm-xfree86 entry.
        + update comment in Caps regarding IBM (AIX) function-key definitions.

20010421
        + modify c++/Makefile.in to link with libncurses++w.a when configured
          for wide-characters (patch by Sven Verdoolaege).
        + add check in _nc_trace_buf() to refrain from freeing a null pointer.
        + improve CF_PROG_INSTALL macro using CF_DIRNAME.
        + update config.guess, config.sub from autoconf 2.49e (alpha).

20010414
        + add secondary check in tic.c, similar_sgr() to see if the reason
          for mismatch was that the individual capabilities used a time-delay
          while sgr did not.  Used this to cleanup mismatches, e.g., in vt100,
          and remove time-delay from Apple_Terminal entries.
        + add Apple_Terminal terminfo entries (Benjamin C W Sittler
          <bsittler@iname.com>).
        + correct definitions of shifted editing keys for xterm-xfree86 -TD
        + fix a bug in test/bs.c from 20010407 (patch by Erik Sigra).
        + prevent relative_move() from doing an overwrite if it detects 8-bit
          characters when configured for UTF-8 (reported by Sven Verdoolaege
          <skimo@kotnet.org>).

20010407
        + add configure checks for strstream.h vscan function, and similar
          stdio-based function which may be used in C++ binding for gcc 3.0
          (reports by George Goffe, Lars Hecking, Mike Castle).
        + rewrite parts of configure.in which used changequote().  That feature
          is broken in the latest autoconf alphas (e.g., 2.49d).
        + add a missing pathname for ncurses_dll.h, needed when building in
          a directory outside the source tree (patch by Sven Verdoolaege
          <skimo@kotnet.org>).
        > fix 2 bugs in test/bs.c Erik Sigra <sigra@home.se>:
        + no ships were ever placed in the last row or in the last column.
          This made the game very easy to win, because you never had to waste
          any shots there, but the computer did.
        + the squares around a sunken ship that belonged to the player were not
          displayed as already hit by the computer, like it does for the
          player.

20010331
        + add some examples of customizing screen's terminfo:
          screen.xterm-xfree86, screen.xterm-r6, screen.teraterm -TD
        + modify screen's terminfo entry to match the khome/kend in screen
          3.09.08 (Debian bug report #92215).
        + correct a memory leak in forms library (report by Stefan Vogtner
          <stefan@vogtner.de>) (patch by Juergen Pfeifer).

20010324
        + change symbols used to guard against repeated includes to begin
          consistently with "NCURSES_" rather than a leading underscore.  There
          are other symbols defined in the header files which begin with a
          leading underscore, but they are part of the legacy interface.
        + reorder includes in c++ binding so that rcs identifiers can be
          compiled-in.
        + add .cc.ii rule to c++ makefile, to get preprocessor output for
          debugging.
        + correct configure script handling of @keyword@ substitutions when the
          --with-manpage-renames option is given (cf:  20000715, fixes Debian
          bug #89939).
        + report stack underflow/overflow in tparm() when tic -cv option is
          given.
        + remove spurious "%|" operator from xterm-xfree86 terminfo entry,
          (reported by Adam Costello <amc@cs.berkeley.edu>, Debian bug #89222).

20010310
        + cleanup of newdemo.c, fixing some ambiguous expressions noted by gcc
          2.95.2, and correcting some conflicting color pair initializations.
        + add missing copyright notice for cursesw.h
        + review, make minor fixes for use of '::' for referring to C-language
          interface from C++ binding.
        + modify configure check for g++ library slightly to accommodate
          nonstandard version number, e.g., <vendor>-2.7 (report by Ronald Ho
          <rho@mipos2.intel.com>).
        + add configure check for c++ <sstream> header, replace hardcoded
          ifdef.
