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

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

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 '@'.
        > 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>).
        > 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
        > 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.
        > 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 (Solaris, AIX).

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 (patch by 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.
        + workaround for pre-release of gcc 3.0 libstdc++, which has dropped
          vscan from strstreambuf to follow standard, use wrapper for C vscanf
          instead (report by George Goffe <grgoffe@excite.com> and Matt Taggart
          <taggart@carmen.fc.hp.com>, fixes Debian .

20010303
        + modify interface of _nc_get_token() to pass 'silent' parameter to it,
          to make quieter loading of /etc/termcap (patch by Todd C Miller).
        + correct a few typos in curs_slk.3x and curs_outopts.3x manpages
          (patch by Todd C Miller).

20010224
        + compiler-warning fixes (reported by Nelson Beebe).

20010210
        + modify screen terminfo entry to use new 3.9.8 feature allowing xterm
          mouse controls -TD

20010203
        + broaden patterns used to match OS/2 EMX in configure script to cover
          variant used in newer config.guess/config.sub
        + remove changequote() calls from configure script, since this feature
          is broken in the autoconf 2.49c alpha, maintainers decline to fix.
        + remove macro callPutChar() from tty_update.c, since this is no longer
          needed (reported by Philippe Blain).
        + add a null-pointer check in tic.c to handle the case when the input
          file is really empty.  Modify the next_char() function in comp_scan.c
          to allow arbitrarily long lines, and incidentally supply a newline to
          files that do not end in a newline.  These changes improve tic's
          recovery from attempts to read binary files, e.g., its output from
          the terminfo database (reported by Bernhard Rosenkraenzer).

20010127
        + revert change to c++/demo.cc from 20001209, which changed definition
          of main() apparently to accommodate cygwin linker, but broke the demo
          program.
        + workaround for broken egcs 2.91.66 which calls member functions
          (i.e., lines() and colors() of NCursesWindow before calling its
          constructor.  Add calls to initialize() in a few constructors which
          did not do this already.
        + use the GNAT preprocessor to make the necessary switch between TRACE
          and NO_TRACE configurations (patch by Juergen Pfeifer).
        > patches by Bernhard Rosenkraenzer:
        + modify kterm terminfo entry to use SCS sequence to support alternate
          character set (it does not work with SI/SO).
        + --with-ospeed=something didn't work.  configure.in checked for a
          $enableval where it should check for $withval.  Also,
          ncurses/llib-lncurses still had a hardcoded short.

20010114
        + correction to my merge of Tom Riddle's patch that broke tic in some
          conditions (reported by Enoch Wexler <enoch@wexler.co.il>) -TD

20010113
        + modify view.c to test halfdelay().  Like other tests, this recognizes
          the 's' and space commands for stopping/starting polled input, shows
          a freerunning clock in the header.  If given a parameter to 's', that
          makes view.c use halfdelay() with that parameter rather than
          nodelay().
        + fix to allow compile with the experimental configure option
          --disable-hashmap.
        + modify postprocess_termcap() to avoid overwriting key_backspace,
          key_left, key_down when processing a non-base entry (report/patch by
          Tom Riddle).
        + modify _nc_wrap_entry(), adding option to reallocate the string
          table, needed in _nc_merge_entry() when merging termcap entries.
          (adapted from report/patch by Tom Riddle <ftr@oracom.com>).
        + modify a few configure script macros to keep $CFLAGS used only for
          compiler options, preprocessor options in $CPPFLAGS.

20001230
        + correct marker positions in lrtest.c after receiving a sigwinch.
        + fix ifdef's in ncurses.c to build against pre-5.2 for testing.
        + fixes to tclock for resizing behavior, redundant computation (report
          and patch by A M Kuchling <akuchlin@mems-exchange.org>).

20001216
        + improved scoansi terminfo entry -TD
        + modify configure script and makefile in Ada95/src to compile a stub
          for the trace functions when ncurses does not provide those.

20001209
        + add ncurses_dll.h and related definitions to support generating DLL's
          with cygwin (adapted from a patch by Charles Wilson
          <cwilson@ece.gatech.edu>, changed NCURSES_EXPORT macro to make it
          work with 'indent').

20001202
        + correct prototypes for some functions in curs_termcap.3x, matching
          termcap.h, which matches X/Open.
        > patch by Juergen Pfeifer:
        + a revised version of the Ada enhancements sent in by "H.
          Nanosecond", aka Eugene V Melaragno <aldomel@ix.netcom.com>.  This
          patch includes
          - small fixes to the existing ncurses binding
          - addition of some more low-level functions to the binding, including
            termcap and terminfo functions
          - An Ada implementation of the "ncurses" test application originally
            written in C.

20001125
        + modify logic in lib_setup.c to allow either lines or columns value
          from terminfo to be used if the screen size cannot be determined
          dynamically rather than requiring both (patch by Ehud Karni
          <ehud@unix.simonwiesel.co.il>).
        + add check in lib_tgoto.c's is_termcap() function to reject null or
          empty strings (reported by Valentin Nechayev <netch@netch.kiev.ua> to
          freebsd-bugs).
        + add definition from configure script that denotes the path-separator,
          which is normally a colon.  The path-separator is a semicolon on
          OS/2 EMX and similar systems which may use a colon within pathnames.
        + alter logic to set default for --disable-overwrite option to set it
          to 'yes' if the --prefix/$prefix value is not /usr/local, thereby
          accommodating the most common cause of problems: gcc's nonstandard
          search rules.  Other locations such as /usr/local/ncurses will
          default to overwriting (report by Lars Hecking <lhecking@nmrc.ie>).

20001118
        + modify default for --disable-overwrite configure option to disable
          if the --prefix or $prefix value is not /usr.
        + add cygwin to systems for which ncurses is installed by default into
          /usr rather than /usr/local.

20001111
        + minor optimization in comp_error.c and lib_termname.c, using
          strncat() to replace strncpy() (patch by Solar Designer).
        + add a use_terminfo_vars() check for $HOME/.termcap, and check for
          geteuid() to use_terminfo_vars() (patch by Solar Designer
          <solar@false.com>).
        + improved cygwin terminfo entry, based on patch by
          <ernie_boyd@yahoo.com>.
        + modify _nc_write_entry() to allow for the possibility that linking
          aliases on a filesystem that ignores case would not succeed because
          the source and destination differ only by case, e.g., NCR260VT300WPP0
          on cygwin (report by Neil Zanella).
        + fix a typo in the curs_deleteln.3x man page (patch by Bernhard
          Rosenkraenzer <bero@redhat.de>).

20001104
        + add configure option --with-ospeed to assist packagers in transition
          to 5.3 change to ospeed type.
        + add/use CharOf() macro to suppress sign-extension of char type on
          platforms where this is a problem in ctype macros, e.g., Solaris.
        + change trace output to binary format.
        + correct a missing quote adjustment in CF_PATH_SYNTAX autoconf
          macro, for OS/2 EMX configuration.
        + rearrange a few configure macros, moving preprocessor options to
          $CPPFLAGS (a now-obsolete version of autoconf did not consistently
          use $CPPFLAGS in both the compile and preprocessor checks).
        + add a check in relative_move() to guard against buffer overflow in
          the overwrite logic.

20001028
        + add message to configure script showing g++ version.
        + resync config.guess, config.sub
        + modify lib_delwin.c, making it return ERR if the window did not exist
          (suggested by Neil Zanella).
        + add cases for FreeBSD 3.1 to tdlint and makellib scripts, used this
          to test/review ncurses library.  (Would use lclint, but it doesn't
          work).
        + reorganized knight.c to avoid forward references.  Correct screen
          updates when backtracking, especially to the first cell.  Add F/B/a
          commands.

20001021 5.2 release for upload to ftp.gnu.org
        + update generated html files from manpages.
        + modify dist.mk to use edit_man.sh to substitute autoconf'd variables
          in html manpages.
        + fix an uninitialized pointer in read_termcap.c (report by Todd C
          Miller, from report/patch by Philip Guenther <guenther@gac.edu>).
        + correct help-message and array limit in knight.c (patch by Brian
          Raiter <breadbox@muppetlabs.com>).
        > patch by Juergen Pfeifer:
        + fix to avoid warning by GNAT-3.13p about use of inconsistent casing
          for some identifiers defined in the standard package.
        + cosmetic change to forms/fty_enum.c

20001014
        + correct an off-by-one position in test/railroad.c which could cause
          wrapping at the right margin.
        + test/repair some issues with libtool configuration.  Make
          --disable-echo force libtool --silent.  (Libtool does not work for
          OS/2 EMX, works partly for SCO - libtool is still very specific to
          gcc).
        + change default of --with-manpage-tbl to "no", since for most of the
          platforms which do have tbl installed, the system "man" program
          understands how to run tbl automatically.
        + minor improvement to force_bar() in comp_parse.c (Bernhard
          Rosenkraenzer <bero@redhat.de>).
        + modify lib_tparm.c to use get_space() before writing terminating
          null character, both for consistency as well as to ensure that if
          save_char() was called immediately before, that the allocated memory
          is enough (patch by Sergei Ivanov).
        + add note about termcap ML capability which is duplicated between two
          different capabilities:  smgl and smglr (reported by Sergei Ivanov
          <svivanov@pdmi.ras.ru>).
        + correct parameter counts in include/Caps for dclk as well as some
          printer-specific capabilities: csnm, defc, scs, scsd, smgtp, smglp.
        > patch by Johnny C Lam <lamj@stat.cmu.edu>:
        + add support for building with libtool (apparently version 1.3.5,
          since old versions do not handle -L../lib), using new configure
          option --with-libtool.
        + add configure option --with-manpage-tbl, which causes the manpages to
          be preprocessed by tbl(1) prior to installation,
        + add configure option --without-curses-h, which causes the
          installation process to install curses.h as ncurses.h and make
          appropriate changes to headers and manpages.

20001009
        + correct order of options/parameters in run_tic.in invocation of tic,
          which did not work with standard getopt() (reported by Ethan
          Butterfield <primus@veris.org>).
        + correct logic for 'reverse' variable in lib_vidattr.c, which was
          setting it true without checking if newmode had A_REVERSE set, e.g.,
          using $TERM=ansi on OS/2 EMX (see 20000917).
        > patch by Todd Miller:
        + add a few missing use_terminfo_vars() and fixes up _nc_tgetent().
          Previously, _nc_cgetset() would still get called on cp so the
          simplest thing is to set cp to NULL if !use_terminfo_vars().
        + added checks for an empty $HOME environment variable.
        > patches by Ilya Zakharevich for OS/2 EMX:
        + modify convert_configure.pl to support INSTALL.  Change compiler
          options in that script to use multithreading, needed for the mouse.
        + modify OS/2 mouse support, retrying as a 2-button mouse if code fails
          to set up a 3-button mouse.
        + improve code for OS/2 mouse support, using _nc_timed_wait() to
          replace select() call.

20001007
        + change type of ospeed variable back to short to match its use in
          legacy applications (reported by Andrey A Chernov).
        + add case to configure script for --enable-rpath on IRIX (patch by
          Albert Chin-A-Young).
        + minor fix to position_check() function, to ensure it gets the whole
          cursor report before decoding.
        + add configure option --disable-assumed-color, to allow pre-5.1
          convention of default colors used for color-pair 0 to be configured
          (see assume_default_colors()).
        + rename configure option --enable-hashmap --disable-hashmap, and
          reorder the configure options, splitting the experimental and
          development
        + add configure option --disable-root-environ, which tells ncurses to
          disregard $TERMINFO and similar environment variables if the current
          user is root, or running setuid/setgid (based on discussion with
          several people).
        + modified misc/run_tic.in to use tic -o, to eliminate dependency on
          $TERMINFO variable for installs.
        + add table entry for plab_norm to tput, so it passes in strings
          for that capability.
        + modify parse_format() in lib_tparm.c to ignore precision if it is
          longer than 10000 (report by Jouko Pynnonen).
        + rewrote limit checks in lib_mvcur.c using new functions
          _nc_safe_strcat(), etc.  Made other related changes to check lengths
          used for strcat/strcpy (report by Jouko Pynnonen
          <jouko@solutions.fi>).

20000930
        + modify several descriptions, including those for setaf, setab, in
          include/Caps to indicate that the entries are parameterized.  This
          information is used to tell which strings are translated when
          converting to termcap.  Fixes a problem where the generated termcap
          would contain a spurious "%p1" for the terminfo "%p1%d".
        + modify ld -rpath options (e.g., Linux, and Solaris) to use an
          absolute pathname for the build tree's lib directory (prompted by
          discussion with Albert Chin-A-Young).
        + modify "make install.man" and "make uninstall.man" to include tack's
          man-page.
        + various fixes for install scripts used to support configure --srcdir
          and --with-install-prefix (reported by Matthew Clarke
          <Matthew_Clarke@mindlink.bc.ca>).
        + make configure script checks on variables $GCC and $GXX consistently
          compare against 'yes' rather than test if they are nonnull, since
          either may be set to the corresponding name of the C or C++ compiler
          (report/patch by Albert Chin-A-Young).

20000923
        + modify rs2 capability in xterm-r6 and similar where cursor
          save/restore bracketed the sequence for resetting video attributes.
          The cursor restore would undo that (from a NetBSD bug report by John
          Hawkinson <jhawk@MIT.EDU>).
        + using parameter check added to tic, corrected 27 typos in
          terminfo.src -TD
        + modify tic to verify that its inputs are really files, in case
          someone tries to read a directory (or /dev/zero).
        + add a check for empty buffers returned by fgets() in comp_scan.c
          next_char() function, in case tic is run on a non-text file (fixes
          a core dump reported by Aaron Campbell <aaron@cs.dal.ca>).
        + add to railroad.c some code exercising tgoto(), providing an
          alternate form of display if the terminal supports cursor addressing.
        + split-out tgoto() again, this time into new file lib_tgoto.c, and
          implement a conventional BSD-style tgoto() which is used if the
          capability string does not contain terminfo-style padding or
          parameters (requested by Andrey A Chernov).
        + add check to tic which reports capabilities that do not reference
          the expected number of parameters.
        + add error checking to infocmp's -v and -m options to ensure that
          the option value is indeed a number.
        + some cleanup of logic in _nc_signal_handler() to verify if SIGWINCH
          handler is setup.  Separated the old/new sigaction data for SIGTSTP
          from the other signals.

20000917
        + add S0, E0 extensions to screen's terminfo entry, which is another
          way to solve the misconfiguration issue -TD
        + completed special case for tgoto from 20000916

20000916
        + update xterm terminfo entries to match XFree86 xterm patch #146 -TD
        + add Matrix Orbital terminfo entries (from Eric Z Ayers
          <eric@ale.org>).
        + add special case to lib_tparm.c to allow 'screen' program to use a
          termcap-style parameter "%." to tgoto() for switching character sets.
        + use LN_S substitution in run_tic.in, to work on OS/2 EMX which has
          no symbolic links.
        + updated notes in README.emx regarding autoconf patches.
        + replace a lookup table in lib_vidattr.c used to decode no_color_video
          with a logic expression (suggested by Philippe Blain).
        + add a/A toggle to ncurses.c 'b' test, which clears/sets alternate
          character set attribute from the displayed text.
        + correct inequality in parameter analysis of rewritten lib_tparm.c
          which had the effect of ignoring p9 in set_attributes (sgr), breaking
          alternate character set (reported by Piotr Majka <charvel@link.pl>).
        + correct ifdef'ing for GCC_PRINTF, GCC_SCANF which would not compile
          with Sun WorkShop compilers since these tokens were empty (cf:
          20000902, reported by Albert Chin-A-Young).

20000909
        + correct an uninitialized parameter to open_tempfile() in tic.c which
          made "tic -I" give an ambiguous error message about tmpnam.
        + add special case in lib_vidattr.c to reset underline and standout for
          devices that have no sgr0 defined (patch by Don Lewis
          <Don.Lewis@tsc.tdk.com>).  Note that this will not work for bold
          mode, since there is no exit-bold-mode capability.
        + improved patch for Make_Enum_Type (patch by Juergen Pfeifer).
        + modify tparm to disallow arithmetic on strings, analyze the varargs
          list to read strings as strings and numbers as numbers.
        + modify tparm's internal function spop() to treat a null pointer as
          an empty string.
        + modify tput program so it can be renamed or invoked via a link as
          'reset' or 'init', producing the same effect as 'tput reset' or 'tput
          init'.
        + add private entrypoint _nc_basename(), use to consolidate related
          code in progs, as well as accommodating OS/2 EMX pathnames.
        + remove NCURSES_CONST line from edit_cfg.sh to compensate for its
          removal (except via AC_SUBST) from configure.in, making
          --enable-const work again (reported by Juergen Pfeifer).
        + regen'd configure to pick up "hpux*" change from 20000902.

20000902
        + modify tset.c to check for transformed "reset" program name, if any.
        + add a check for null pointer in Make_Enum_Type() (reported by Steven
          W Orr <steveo@world.std.com>).
        + change functions _nc_parse_entry() and postprocess_termcap() to avoid
          using strtok(), because it is non-reentrant (reported by Andrey A
          Chernov <ache@nagual.pp.ru>).
        + remove "hpux10.*" case from CF_SHARED_OPTS configure script macro.
          This differed from the "hpux*" case by using reversed symbolic
          links, which made the 5.1 version not match the configuration of
          5.0 shared libraries (reported by Albert Chin-A-Young).
        + correct a dependency in Ada95/src/Makefile.in which prevented
          building with configure --srcdir (patch by H Nanosecond
          <aldomel@ix.netcom.com>).
        + modify ifdef's in curses.h.in to avoid warning if GCC_PRINTF or
          GCC_SCANF was not previously defined (reported by Pavel Roskin
          <proski@gnu.org>).
        + add MKncurses_def.sh to generate fallback definitions for
          ncurses_cfg.h, to quiet gcc -Wundef warnings, modified ifdef's in
          code to consistently use "#if" rather than "#ifdef".

20000826
        + add QNX qansi entries to terminfo -TD
        + add os2 entry to misc/emx.src (<jmcoopr@webmail.bmi.net>).
        + add configure option --with-database to allow specifying a different
          terminfo source-file to install.  On OS/2 EMX, this defaults to
          misc/emx.src
        + change misc/run_tic.sh to derive it from misc/run_tic.in, to simplify
          setting .exe extension on OS/2 EMX.
        + add .exe extension in Ada95/gen/Makefile.in,
          Ada95/samples/Makefile.in, for OS/2 EMX (reported by
          <jmcoopr@webmail.bmi.net>).
        + add configure check for filesystems (such as OS/2 EMX) which do not
          distinguish between upper/lowercase filenames, use this to fix tags
          rules in makefiles.
        + initialize fds[] array to 0's in _nc_timed_wait(); apparently poll()
          only sets the revents members of that array when there is activity
          corresponding to the related file (report by Glenn Cooper
          <gcooper@qantas.com.au>, using Purify on Solaris 5.6).
        + change configure script to use AC_CANONICAL_SYSTEM rather than
          AC_CANONICAL_HOST, which means that configure --target will set
          a default program-prefix.
        + add note on cross-compiling to INSTALL (which does not rely on the
          AC_CANONICAL_* macros).

20000819
        + add cases for EMX OS/2 to config.guess, config.sub
        + new version of config.guess, config.sub from lynx 2.8.4dev.7
        + add definitions via transform.h to allow tic and tput to check for
          the transformed aliases rather than the original infotocap, etc.
        + simplify transform-expressions in progs/Makefile.in, make the
          uninstall rule work for transformed program names.
        + change symbol used by --install-prefix configure option from
          INSTALL_PREFIX to DESTDIR (the latter has become common usage
          although the name is misleading).
        + modify programs to use curses_version() string to report the version
          of ncurses with which they are compiled rather than the
          NCURSES_VERSION string.  The function returns the patch level in
          addition to the major and minor version numbers.

20000812
        + modify CF_MAN_PAGES configure macro to make transformed program names
          a parameter to that macro rather than embedding them in the macro.
        + newer config.guess, config.sub (reference version used in lynx
          2.8.4dev.7).
        + add configure option --with-default-terminfo-dir=DIR to allow
          specifying the default terminfo database directory (request by Albert
          Chin-A-Young).
        + minor updates for terminfo.src from FreeBSD termcap change-history.
        + correct notes in README and INSTALL regarding documentation files
          that were moved from misc directory to doc (report by Rich Kulawiec
          <rsk@gsp.org>).
        + change most remaining unquoted parameters of 'test' in configure
          script to use quotes, for instance fixing a problem in the
          --disable-database option (reported by Christian Mondrup
          <scancm@biobase.dk>).
        + minor adjustments to work around some of the incompatibilities/bugs
          in autoconf 2.29a alpha.
        + add -I/usr/local/include when --with-ncurses option is used in
          test/configure script.
        + correct logic in adjust_cancels(), which did not check both
          alternatives when reclassifying an extended name between boolean,
          number and string, causing an infinite loop in tic.

20000730
        + correct a missing backslash in curses.priv.h

20000729
        + change handling of non_dest_scroll_region in tty_update.c to clear
          text after it is shifted in rather than before shifting out.  Also
          correct row computation (reported by Ruediger Kuhlmann
          <uck4@rz.uni-karlsruhe.de>).
        + add/use new trace function to display chtype values from winch() and
          getbkgd().
        + add trace mask TRACE_ATTRS, alter several existing _tracef calls that
          trace attribute changes under TRACE_CALLS to use this.
        + modify MKlib_gen.sh so that functions returning chtype will call
          returnChar().
        + add returnChar() trace, for functions returning chtype.
        + change indent.pro to line up parenthesis.

20000722
        + fix a heap problem with the c++ binding (report by
          <alexander_liberson@ninewest.com>, patch by Juergen Pfeifer).
        + minor adjustment to ClrToEOL() to handle an out-of-bounds parameter.
        + modify the check for big-core to force a couple of memory accesses,
          which may work as needed for older/less-capable machines (if not,
          there's still the explicit configure option).
        > fixes based on diff's for Amiga and BeOS found at
          http://www.mathematik.uni-karlsruhe.de/~kuhlmann/cross/ncurses/
        + alter definition of NCURSES_CONST to make it non-empty.
        + add amiga-vnc terminfo entry.
        + redefine 'TEXT' in menu.h for AMIGA, since it is reported to have
          an (unspecified) symbol conflict.
        + replaced case-statement in _nc_tracebits() for CSIZE with a table to
          simplify working around implementations that define random
          combinations of the related macros to zero.
        + modify configure test for tcgetattr() to allow for old
          implementations, e.g., on BeOS, which only defined it as a macro.
        > patches by Bruno Haible:
        + when checking LC_ALL/LC_CTYPE/LANG environment variables for UTF-8
          locale, ignore those which are set to an empty value, as per SUSV2.
        + encode 0xFFFD in UTF-8 with 3 bytes, not 2.
        + modify _nc_utf8_outch() to avoid sign-extension when checking for
          out-of-range value.

20000715
        + correct manlinks.sed script to avoid using ERE "\+", which is not
          understood by older versions of sed (patch by Albert Chin-A-Young).
        + implement configure script options that transform installed program
          names, e.g., --program-prefix, including the manpage names and cross
          references (patch by Albert Chin-A-Young <china@thewrittenword.com>).
        + correct several mismatches between manpage filename and ".TH"
          directives, renaming dft_fgbg.3x to default_colors.3x and
          menu_attribs.3x to menu_attributes.3x (report by Todd C Miller).
        + correct missing includes for <string.h> in several places, including
          the C++ binding.  This is not noted by gcc unless we use the
          -fno-builtin option (reported by Igor Schein <igor@txc.com>).
        + modified progs/tset.c and tack/sysdep.c to build with sgttyb
          interface if neither termio or termios is available.  Tested this
          with FreeBSD 2.1.5 (which does have termios - but the sgttyb does
          work).

20000708 5.1 release for upload to ftp.gnu.org
        + document configure options in INSTALL.
        + add man-page for ncurses trace functions.
        + correct return value shown in curs_touch.3x for is_linetouched() and
          is_wintouched(), in curs_initscr.3x for isendwin(), and in
          curs_termattr.3x for has_ic() and has_il().
        + add prototypes for touchline() and touchwin(), adding them to the
          list of generated functions.
        + modify fifo_push() to put ERR into the fifo just like other values to
          return from wgetch().  It was returning without doing that, making
          end-of-file condition incorrectly return a 0 (reported by Todd C
          Miller).
        + uncomment CC_SHARED_OPTS for progs and tack (see 971115), since they
          are needed for SCO OpenServer.
        + move _nc_disable_period from free_ttype.c to comp_scan.c to appease
          dynamic loaders on SCO and IRIX64.
        + add "-a" option to test/ncurses.c to invoke assume_default_colors()
          for testing.
        + correct assignment in assume_default_colors() which tells ncurses
          whether to use default colors, or the assumed ones (reported by Gary
          Funck <gary@Intrepid.Com>).
        + review/correct logic in mk-1st.awk for making symbolic links for
          shared libraries, in particular for FreeBSD, etc.
        + regenerate misc/*.def files for OS/2 EMX dll's.
        + correct quoting of values for CC_SHARED_OPTS in aclocal.m4 for
          cases openbsd2*, openbsd*, freebsd* and netbsd* (patch by Peter
          Wemm) (err in 20000610).
        + minor updates to release notes, as well as adding/updating URLs for
          examples cited in announce.html
        > several fixes from Philippe Blain <philippe.blain2@freesbee.fr>:
        + correct placement of ifdef for NCURSES_XNAMES in function
          _nc_free_termtype(), fixes a memory leak.
        + add a call to _nc_synchook() to the end of function whline() like
          that in wvline() (difference was in 1.9.4).
        + make ClearScreen() a little faster by moving two instances of
          UpdateAttr() out of for-loops.
        + simplify ClrBottom() by eliminating the tstLine data, using for-loops
          (cf: 960428).

20000701 pre-release
        + change minor version to 1, i.e., ncurses 5.1
        + add experimental configure option --enable-colorfgbg to check for
          $COLORTERM variable as set by rxvt/aterm/Eterm.
        + add Eterm terminfo entry (Michael Jennings <mej@valinux.com>).
        + modify manlinks.sed to pick aliases from the SYNOPSIS section, and
          several manpages so manlinks.sed can find aliases for creating
          symbolic links.
        + add explanation to run_tic.sh regarding extended terminal
          capabilities.
        + change message format for edit_cfg.sh, since some people interpret
          it as a warning.
        + correct unescaped '$' in sysv5uw7*|unix_sv* rule for CF_SHARED_OPTS
          configure macro (report by Thanh Ma <Thanh.Ma@casi-rusco.com>).
        + correct logic in lib_twait.c as used by lib_mouse.c for GPM mouse
          support when poll() is used rather than select() (prompted by
          discussion with David Allen <DAllen24@aol.com>).

20000624 pre-release
        + modify TransformLine() to check for cells with different color pairs
          that happen to render the same display colors.
        + apply $NCURSES_NO_PADDING to cost-computation in mvcur().
        + improve cost computation in PutRange() by accounting for the use
          of parm_right_cursor in mvcur().
        + correct cost computation in EmitRange(), which was not using the
          normalized value for cursor_address.
        + newer config.guess, config.sub (reference version used in TIN 1.5.6).

20000617
        + update config.guess, config.sub (reference version used in PCRE 3.2).
        + resync changes to gnathtml against version 1.22, regenerated html
          files under doc/html/ada using this (1.22.1.1).
        + regenerated html files under doc/html/man after correcting top and
          bottom margin options for man2html in dist.mk
        + minor fixes to test programs ncurses 'i' and testcurs program to make
          the subwindow's background color cover the subwindow.
        + modify configure script so AC_MSG_ERROR is temporarily defined to a
          warning in AC_PROG_CXX to make it recover from a missing C++ compiler
          without requiring user to add --without-cxx option (from comment by
          Akim Demaille <akim@epita.fr> to autoconf mailing list).
        + modify headers.sh to avoid creating temporary files in the build
          directory when installing headers (reported by Sergei Pokrovsky
          <pok@nbsp.nsk.su>)

20000610
        + regenerated the html files under doc/html/ada/files and
          doc/html/ada/funcs with a slightly-improved gnathtml.
        + add kmous capability to linux terminfo entry to allow it to use
          xterm-style events provided by gpm patch by Joerg Schoen.
        + make the configure macro CF_SHARED_OPTS a little smarter by testing
          if -fPIC is supported by gcc rather than -fpic.  The former option
          allows larger symbol tables.
        + update config.guess and config.sub (patches by
          Kevin Buettner <kev@primenet.com> for elf64_ia64
          Bernd Kuemmerlen <bkuemmer@mevis.de> and MacOS X).
        + add warning for 'tic -cv' about use of '^?' in terminfo source, which
          is an extension.

20000527
        + modify echo() behavior of getch() to match Solaris curses for
          carriage return and backspace (reported by Neil Zanella).
        + change _nc_flush() to a function.
        + modify delscreen() to check if the output stream has been closed, and
          if so, free the buffer allocated for setbuf (this provides an
          ncurses-specific way to avoid a memory leak when repeatedly calling
          newterm reported by Chipp C <at_1@zdnetonebox.com>).
        + correct typo in curs_getch.3x manpage regarding noecho (reported by
          David Malone <dwmalone@maths.tcd.ie>).
        + add a "make libs" rule.
        + make the Ada95 interface build with configure --enable-widec.
        + if the configure --enable-widec option is given, append 'w' to names
          of the generated libraries (e.g., libncursesw.so) to avoid conflict
          with existing ncurses libraries.

20000520
        + modify view.c to make a rudimentary viewer of UTF-8 text if ncurses
          is configured with the experimental wide-character support.
        + add a simple UTF-8 output driver to the experimental wide-character
          support.  If any of the environment variables LC_ALL, LC_CTYPE or
          LANG contain the string "UTF-8", this driver will be used to
          translate the output to UTF-8.  This works with XFree86 xterm.
        + modify configure script to allow building shared libraries on BeOS
          (from a patch by by Valeriy E Ushakov).
        + modify lib_addch.c to allow repeated update to the lower-right
          corner, rather than displaying only the first character written until
          the cursor is moved.  Recent versions of SVr4 curses can update the
          lower-right corner, and behave this way (reported by Neil Zanella).
        + add a limit-check in _nc_do_color(), to avoid using invalid color
          pair value (from bug report by Brendan O'Dea <bod@compusol.com.au>).

20000513
        + the tack program knows how to use smcup and rmcup but the "show caps
          that can be tested" feature did not reflect this knowledge.  Correct
          the display in the menu tack/test/edit/c (patch by Daniel Weaver).
        + xterm-16color does allow bold+colors, removed ncv#32 from that
          terminfo entry.

20000506
        + correct assignment to SP->_has_sgr_39_49 in lib_dft_fgbg.c, which
          broke check for screen's AX capability (reported by Valeriy E Ushakov
          <uwe@ptc.spbu.ru>).
        + change man2html rule in dist.mk to workaround bug in some
          man-programs that ignores locale when rendering hyphenation.
        + change web- and ftp-site to dickey.his.com

20000429
        + move _nc_curr_token from parse_entry.c to comp_scan.c, to work around
          problem linking tack on MacOS X DP3.
        + include <sys/time.h> in lib_napms.c to compile on MacOS X DP3
          (reported by Gerben Wierda <wierda@holmes.nl>).
        + modify lib_vidattr.c to check for ncv fixes when pair-0 is not
          default colors.
        + add -d option to ncurses.c, to turn on default-colors for testing.
        + add a check to _nc_makenew() to ensure that newwin() and newpad()
          calls do not silently fail by passing too-large limits.
        + add symbol NCURSES_SIZE_T to use rather than explicit 'short' for
          internal window and pad sizes.  Note that since this is visible in
          the WINDOW struct, it would be an ABI change to make this an 'int'
          (prompted by a question by Bastian Trompetter
          <btrompetter@firemail.de>, who attempted to create a 96000-line pad).

20000422
        + add mgterm terminfo entry from NetBSD, minor adjustments to sun-ss5,
          aixterm entries -TD
        + modify tack/ansi.c to make it more tolerant of bad ANSI replies.  An
          example of an illegal ANSI resonse can be found using Microsoft's
          Telnet client.  A correct display can be found using a VT-4xx
          terminal or XFree86 xterm with:
                XTerm*VT100*decTerminalID:  450
          (patch by Daniel Weaver).
        + modify gdc.c to recognize 'q' for quit, 's' for single-step and ' '
          for resume.  Add '-n' option to force gdc's standard input to
          /dev/null, to both illustrate the use of newterm() for specifying
          alternate inputs as well as for testing signal handling.
        + minor fix for configure option --with-manpage-symlinks, for target
          directories that contain a period ('.') (reported by Larry Virden).

20000415
        + minor additions to beterm entry (feedback from Rico Tudor) -TD
        + corrections/updates for some IBM terminfo entries -TD
        + modify _nc_screen_wrap() so that when exiting curses mode with
          non-default colors, the last line on the screen will be cleared to
          the screen's default colors (request by Alexander Lukyanov).
        + modify ncurses.c 'r' example to set nonl(), allowing control/M to be
          read for demonstrating the REQ_NEW_LINE operation (prompted by a
          question by Tony L Keith" <tlkeith@keithconsulting.com>).
        + modify ncurses.c 'r' example of field_info() to work on Solaris 2.7,
          documented extension of ncurses which allows a zero pointer.
        + modify fmt_complex() to avoid buffer overflow in case of excess
          recursion, and to recognize "%e%?" as a synonym for else-if, which
          means that it will not recur for that special case.
        + add logic to support $TERMCAP variable in case the USE_GETCAP symbol
          is defined (patch by Todd C Miller).
        + modify one of the m4 files used to generate the Ada95 sources,
          to avoid using the token "symbols" (patch by Juergen Pfeifer).

20000408
        + add terminfo entries bsdos-pc-m, bsdos-pc-mono (Jeffrey C Honig)
        + correct spelling error in terminfo entry name:  bq300-rv was given as
          bg300-rv in esr's version.
        + modify redrawwin() macro so its parameter is fully parenthesized
          (fixes Debian bug report #61088).
        + correct formatting error in dump_entry() which set incorrect column
          value when no newline trimming was needed at the end of an entry,
          before appending "use=" clauses (cf: 960406).

20000401
        + add configure option --with-manpage-symlinks
        + change unctrl() to render C1 characters (128-159) as ~@, ~A, etc.
        + change makefiles so trace() function is provided only if TRACE is
          defined, e.g., in the debug library.  Modify related calls to
          _tracechar() to use unctrl() instead.

20000325
        + add screen's AX capability (for ECMA SGR 39 and 49) to applicable
          terminfo entries, use presence of this as a check for a small
          improvement in setting default colors.
        + improve logic in _nc_do_color() implementing assume_default_colors()
          by passing in previous color pair info to eliminate redundant call to
          set_original_colors().  (Part of this is from a patch by Alexander
          Lukyanov).
        + modify warning in _nc_trans_string() about a possibly too-long string
          to do this once only rather than for each character past the
          threshold (600).  Change interface of _nc_trans_string() to allow
          check for buffer overflow.
        + correct use of memset in _nc_read_entry_source() to initialize ENTRY
          struct each time before reading new data into it, rather than once
          per loop (cf:  990301).  This affects multi-entry in-core operations
          such as "infocmp -Fa".

20000319
        + remove a spurious pointer increment in _nc_infotocap() changes from
          20000311.  Add check for '.' in format of number, since that also
          is not permitted in termcap.
        + correct typo in rxvt-basic terminfo from temporary change made while
          integrating 20000318.

20000318
        + revert part of the vt220 change (request by Todd C Miller).
        + add ansi-* terminfo entries from Eric's version.
        + add -a option to tic and infocmp, which retains commented-out
          capabilities during source translation/comparison, e.g., captoinfo
          and infotocap.
        + modify cardfile.c to display an empty card if no input data file is
          found, fixes a core dump in that case (reported by Bruno Haible).
        + correct bracketing in CF_MATH_LIB configure macro, which gave wrong
          result for OS/2 EMX.
        + supply required parameter for _nc_resolve_uses() call in
          read_termcap.c, overlooked in 20000311 (reported by Todd C Miller).
        > patches by Bruno Haible <haible@ilog.fr>:
        + fix a compiler warning in fty_enum.c
        + correct LIB_PREFIX expression for DEPS_CURSES in progs, tack
          makefiles, which resulted in redundant linking (cf: 20000122).

20000311
        + make ifdef's for BROKEN_LINKER consistent (patch by Todd C Miller).
        + improved tack/README (patch by Daniel Weaver).
        + modify tput.c to ensure that unspecified parameters are passed to
          tparm() as 0's.
        + add a few checks in infocmp to guard against buffer overflow when
          displaying string capabilities.
        + add check for zero-uses in infocmp's file_comparison() function
          before calling _nc_align_termtype().  Otherwise one parameter is
          indexed past the end of the uses-array.
        + add an option -q to infocmp to specify the less verbose output,
          keeping the existing format as the default, though not retaining the
          previous behavior that made the -F option compare each entry to
          itself.
        + adapted patch by Eric Raymond to make infocmp -F less verbose
          (the submitted patch was unusable because it did not compile
          properly):
          + modify write_entry.c to ensure that absent or cancelled booleans
            are written as FALSE, for consistency with infocmp which now
            assumes this.  Note that for the small-core configuration, tic
            may not produce the same result as before.
          + change some private library interfaces used by infocmp, e.g.,
            _nc_resolve_uses().
          + add a check in _nc_infotocap() to ensure that cm-style capabilities
            accept only %d codes when converting the format from terminfo to
            termcap.
          + modify ENTRY struct to separate the data in 'parent' into the name
            and link values (the original idea to merge both into 'parent' was
            not good).
          + discard repair_acsc(tterm);
        > patch by Juergen Pfeifer:
        + drop support for gnat 3.10
        + move generated documentation and html files under ./doc directory,
          adding makefile rules for this to dist.mk

20000304
        + correct conflicting use of tparm() in 20000226 change to tic, which
          made it check only one entry at a time.
        + fix errors in ncurses-intro.html and hackguide.html shown by Dave
          Raggett's tidy.
        + make the example in ncurses-intro.html do something plausible, and
          corrected misleading comment (reported by Neil Zanella).
        + modify pnoutrefresh() to set newscr->_leaveok as wnoutrefresh() does,
          to fix a case where the cursor position was not updated as in
          Solaris  (patch by David Mosberger <davidm@hpl.hp.com>).
        + add a limit-check for wresize() to ensure that a subwindow does not
          address out of bounds.
        + correct offsets used for subwindows in wresize() (patch by Michael
          Andres <ma@suse.de>).
        + regenerate html'ized manual pages with man2html 3.0.1 (patch by
          Juergen Pfeifer).  This generated a file with a space in its name,
          which I removed.
        + fix a few spelling errors in tack.
        + modify tack/Makefile.in to match linker options of progs/Makefile.in;
          otherwise it does not build properly for older HPUX shared library
          configurations.
        + add several terminfo entries from esr's "11.0".

20000226
        + make 'tput flash' work properly for xterm by flushing output in
          delay_output() when using napms(), and modifying xterm's terminfo to
          specify no padding character.  Otherwise, xterm's reported baud rate
          can mislead ncurses into producing too few padding characters
          (Debian #58530).
        + add a check to tic for consistency between sgr and the separate
          capabilities such as smso, use this to check/correct several
          terminfo entries (Debian #58530).
        + add a check to tic if cvvis is the same as cnorm, adjusted several
          terminfo entries to remove the conflict (Debian #58530).
        + correct prototype shown in attr_set()/wattr_set() manpages (fixes
          Debian #53962).
        + minor clarification for curs_set() and leaveok() manpages.
        + use mkstemp() for creating temporary file for tic's processing of
          $TERMCAP contents (fixes Debian #56465).
        + correct two errors from integrating Alexander's changes:  did not
          handle the non-bce case properly in can_erase_with() (noted by
          Alexander), and left fg/bg uninitialized in the pair-zero case of
          _nc_do_color() (reported by Dr Werner Fink <werner@suse.de> and
          Ismael Cordeiro <ismael@cordeiro.com>).

20000219
        + store default-color code consistently as C_MASK, even if given as
          -1 for convenience (adapted from patches by Alexander Lukyanov).
        > patches by Alexander Lukyanov:
        + change can_clear_with() macro to accommodate logic for
          assume_default_colors(), making most of the FILL_BCE logic
          unnecessary.  Made can_clear_with() an inline function to make it
          simpler to read.

20000212
        + corrected form of recent copyright dates.
        + minor corrections to xterm-xf86-v333 terminfo entry -TD
        > patches by Alexander Lukyanov:
        + reworded dft_fgbg.3x to avoid assuming that the terminal's default
          colors are white on black.
        + fix initialization of tstLine so that it is filled with current blank
          character in any case.  Previously it was possible to have it filled
          with old blank.  The wrong over-optimization was introduced in 991002
          patch.  (it is not very critical as the only bad effect is not using
          clr_eos for clearing if blank has changed).

20000205
        + minor corrections/updates to several terminfo entries: rxvt-basic,
          vt520, vt525, ibm5151, xterm-xf86-v40 -TD
        + modify ifdef's for poll() to allow it to use <sys/poll.h>, thereby
          allowing poll() to be used on Linux.
        + add CF_FUNC_POLL macro to check if poll() is able to select from
          standard input.  If not we will not use it, preferring select()
          (adapted from patch by Michael Pakovic <mpakovic@fdn.com>).
        + update CF_SHARED_OPTS macro for SCO Unixware 7.1 to allow building
          shared libraries (reported/tested by Thanh <thanhma@mediaone.net>).
        + override $LANGUAGE in build to avoid incorrect ordering of keynames.
        + correct CF_MATH_LIB parameter, must be sin(x), not sqrt(x).

20000122
        + resync CF_CHECK_ERRNO and CF_LIB_PREFIX macros from tin and xterm.
        + modify CF_MATH_LIB configure macro to parameterize the test function
          used, for reuse in dialog and similar packages.
        + correct tests for file-descriptors in OS/2 EMX mouse support.  A
          negative value could be used by FD_SET, causing the select() call
          to wait indefinitely.

20000115
        + additional fixes for non-bce terminals (handling of delete_character)
          to work when assume_default_colors() is not specified.
        + modify warning message from _nc_parse_entry() regarding extended
          capability names to print only if tic/infocmp/toe have the -v flag
          set, and not at all in ordinary user applications.  Otherwise, this
          warning would be shown for screen's extended capabilities in programs
          that use the termcap interface (reported by Todd C Miller).
        + modify use of _nc_tracing from programs such as tic so their debug
          level is not in the same range as values set by trace() function.
        + small panel header cleanup (patch by Juergen Pfeifer).
        + add 'railroad' demo for termcap interface.
        + modify 'tic' to write its usage message to stderr (patch by Todd C
          Miller).

20000108
        + add prototype for erase() to curses.h.in, needed to make test
          programs build with c++/g++.
        + add .c.i and .c.h suffix rules to generated makefiles, for debugging.
        + correct install rule for tack.1; it assumed that file was in the
          current directory (reported by Mike Castle <dalgoda@ix.netcom.com>).
        + modify terminfo/termcap translation to suppress acsc before trying
          sgr if the entry would be too large (patch by Todd C Miller).
        + document a special case of incompatiblity between ncurses 4.2 and
          5.0, add a section for this in INSTALL.
        + add TRACE_DATABASE flag for trace().

20000101
        + update mach, add mach-color terminfo entries based on Debian diffs
          for ncurses 5.0 -TD
        + add entries for xterm-hp, xterm-vt220, xterm-vt52 and xterm-noapp
          terminfo entries -TD
        + change OTrs capabilities to rs2 in terminfo.src -TD
        + add obsolete and extended capabilities to 'screen' terminfo -TD
        + corrected conversion from terminfo rs2 to termcap rs (cf: 980704)
        + make conversion to termcap ug (underline glitch) more consistently
          applied.
        + fix out-of-scope use of 'personal[]' buffer in 'toe' (this error
          was in the original pre-1.9.7 version, when $HOME/.terminfo was
          introduced).
        + modify 'toe' to ignore terminfo directories to which it has no
          permissions.
        + modify read_termtype(), fixing 'toe', which could dump core when it
          found an incomplete entry such as "dumb" because it did not
          initialize its buffer for _nc_read_file_entry().
        + use -fPIC rather than -fpic for shared libraries on Linux, not
          needed for i386 but some ports (from Debian diffs for 5.0).
        + use explicit VALID_NUMERIC() checks in a few places that had been
          overlooked, and add a check to ensure that init_tabs is nonzero,
          to avoid divide-by-zero (reported by Todd C Miller).
        + minor fix for CF_ANSI_CC_CHECK configure macro, for HPUX 10.x (from
          tin).

19991218
        + reorder tests during mouse initialization to allow for gpm to run in
          xterm, or for xterm to be used under OS/2 EMX.  Also drop test for
          $DISPLAY in favor of kmous=\E[M or $TERM containing "xterm" (report
          by Christian Weisgerber <naddy@mips.rhein-neckar.de>).
        + modify raw() and noraw() to clear/restore IEXTEN flag which affects
          stty lnext on systems such as FreeBSD (report by Bruce Evans
          <bde@zeta.org.au>, via Jason Evans <jasone@canonware.com>).
        + fix a potential (but unlikely) buffer overflow in failed() function
          of tset.c (reported by Todd C Miller).
        + add manual-page for ncurses extensions, documented curses_version(),
          use_extended_names().

19991211
        + treat as untranslatable to termcap those terminfo strings which
          contain non-decimal formatting, e.g., hexadecimal or octal.
        + correct commented-out capabilities that cannot be translated to
          termcap, which did not check if a colon must be escaped.
        + correct termcap translation for "%>" and "%+", which did not check
          if a colon must be escaped, for instance.
        + use save_string/save_char for _nc_captoinfo() to eliminate fixed
          buffer (originally for _nc_infotocap() in 960301 -TD).
        + correct expression used for terminfo equivalent of termcap %B,
          adjust regent100 entry which uses this.
        + some cleanup and commenting of ad hoc cases in _nc_infotocap().
        + eliminate a fixed-buffer in tic, used for translating comments.
        + add manpage for infotocap

19991204
        + add kvt and gnome terminfo entries -TD
        + correct translation of "%%" by infotocap, which was emitted as "%".
        + add "obsolete" termcap strings to terminfo.src
        + modify infocmp to default to showing obsolete capabilities rather
          than terminfo only.
        + modify write_entry.c so that if extended names (i.e., configure
          --enable-tcap-names) are active, then tic will also write "obsolete"
          capabilities that are present in the terminfo source.
        + modify tic so that when running as captoinfo or infotocap, it
          initializes the output format as in -C and -I options, respectively.
        + improve infocmp and tic -f option by splitting long strings that do
          not have if-then-else construct, but do have parameters, e.g., the
          initc for xterm-88color.
        + refine MKtermsort.sh slightly by using bool for the *_from_termcap
          arrays.

19991127
        + additional fixes for non-bce terminals (handling of clear_screen,
          clr_eol, clr_eos, scrolling) to work when assume_default_colors() is
          not specified.
        + several small changes to xterm terminfo entries -TD.
        + move logic for _nc_windows in lib_freeall.c inside check for nonnull
          SP, since it is part of that struct.
        + remove obsolete shlib-versions, which was unintentionally re-added
          in 970927.
        + modify infocmp -e, -E options to ensure that generated fallback.c
          type for Booleans agrees with term.h (reported by Eric Norum
          <eric@cls.usask.ca>).
        + correct configure script's use of $LIB_PREFIX, which did not work
          for installing the c++ directory if $libdir did not end with "/lib"
          (reported by Huy Le <huyle@ugcs.caltech.edu>).
        + modify infocmp so -L and -f options work together.
        + modify the initialization of SP->_color_table[] in start_color() so
          that color_content() will return usable values for COLORS greater
          than 8.
        + modify ncurses 'd' test in case COLORS is greater than 16, e.g., for
          xterm-88color, to limit the displayed/computed colors to 16.
        > patch by Juergen Pfeifer:
        + simplify coding of the panel library according to suggestions by
          Philippe Blain.
        + improve macro coding for a few macros in curses.priv.h

19991113
        + modify treatment of color pair 0 so that if ncurses is configured
          to support default colors, and they are not active, then ncurses
          will set that explicitly, not relying on orig_colors or orig_pair.
        + add new extension, assume_default_colors() to provide better control
          over the use of default colors.
        + modify test programs to use more-specific ifdef's for existence of
          wresize(), resizeterm() and use_default_colors().
        + modify configure script to add specific ifdef's for some functions
          that are included when --enable-ext-funcs is in effect, so their
          existence can be ifdef'd in the test programs.
        + reorder some configure options, moving those extensions that have
          evolved from experimental status into a new section.
        + change configure --enable-tcap-names to enable this by default.

19991106
        + install tack's manpage (reported by Robert Weiner
          <robert@progplus.com>)
        + correct worm.c's handling of KEY_RESIZE (patch by Frank Heckenbach).
        + modify curses.h.in, undef'ing some symbols to avoid conflict with C++
          STL (reported by Matt Gerassimoff <mgeras@ticon.net>)

19991030
        + modify linux terminfo entry to indicate that dim does not mix with
          color (reported by Klaus Weide <kweide@enteract.com>).
        + correct several typos in terminfo entries related to missing '['
          in CSI's -TD
        + fix several compiler warnings in c++ binding (reported by Tim
          Mooney for alphaev56-dec-osf4.0f
        + rename parameter of _nc_free_entries() to accommodate lint.
        + correct lint rule for tack, used incorrect list of source files.
        + add case to config.guess, config.sub for Rhapsody.
        + improve configure tests for libg++ and libstdc++ by omitting the
          math library (which is missing on Rhapsody), and improved test for
          the math library itself (adapted from path by Nelson H. F. Beebe).
        + explicitly initialize to zero several data items which were
          implicitly initialized, e.g., cur_term.  If not explicitly
          initialized, their storage type is C (common), and causes problems
          linking on Rhapsody 5.5 using gcc 2.7.2.1 (reported by Nelson H. F.
          Beebe).
        + modify Ada95 binding to not include the linker option for Ada
          bindings in the Ada headers, but in the Makefiles instead (patch by
          Juergen Pfeifer).

19991023 5.0 release for upload to ftp.gnu.org
        + effective with release of 5.0, change NCURSES_VERSION_PATCH to
          4-digit year.
        + add function curses_version(), to return ncurses library version
          (request by Bob van der Poel).
        + remove rmam, smam from cygwin terminfo entry.
        + modify FreeBSD cons25 terminfo entry to add cnorm and cvvis, as well
          as update ncv to indicate that 'dim' conflicts with colors.
        + modify configure script to use symbolic links for FreeBSD shared
          libraries by default.
        + correct ranf() function in rain and worm programs to ensure it does
          not return 1.0
        + hide the cursor in hanoi.c if it is running automatically.
        + amend lrtest.c to account for optimizations that exploit margin
          wrapping.
        + add a simple terminfo demo, dots.c
        + modify SIGINT/SIGQUIT handler to set a flag used in _nc_outch() to
          tell it to use write() rather than putc(), since the latter is not
          safe in a signal handler according to POSIX.
        + add/use internal macros _nc_flush() and NC_OUTPUT to hide details
          of output-file pointer in ncurses library.
        + uncomment CC_SHARED_OPTS (see 971115), since they are needed for SCO
          OpenServer.
        + correct CC_SHARED_OPTS for building shared libraries for SCO
          OpenServer.
        + remove usleep() from alternatives in napms(), since it may interact
          with alarm(), causing a process to be interrupted by SIGALRM (with
          advice from Bela Lubkin).
        + modify terminal_interface-curses-forms.ads.m4 to build/work with
          GNAT 3.10 (patch by Juergen Pfeifer).
        + remove part of CF_GPP_LIBRARY configure-script macro, which did not
          work with gcc 2.7.2.3
        + minor fix to test/tclock.c to avoid beeping more than once per second
        + add 's' and ' ' decoding to test/rain.c

991016  pre-release
        + corrected BeOS code for lib_twait.c, making nodelay() function work.

991009  pre-release
        + correct ncurses' value for cursor-column in PutCharLR(), which was
          off-by-one in one case (patch by Ilya Zakharevich).
        + fix some minor errors in position_check() debugging code, found while
          using this to validate the PutCharLR() patch.
        + modify firework, lrtest, worm examples to be resizable, and to
          recognize 'q' for quit, 's' for single-step and ' ' for resume.
        + restore reverted change to  terminal_interface-curses-forms.ads.m4,
          add a note on building with gnat 3.10p to Ada95/TODO.
        + add a copy of the standalone configure script for the test-directory
          to simplify testing on SCO and Solaris.

991002  pre-release
        + minor fixes for _nc_msec_cost(), color_content(), pair_content(),
          _nc_freewin(), ClrBottom() and onscreen_mvcur() (analysis by Philippe
          Blain, comments by Alexander Lukyanov).
        + simplify definition of PANEL and eliminate internal functions
          _nc_calculate_obscure(), _nc_free_obscure() and _nc_override(),
          (patch by Juergen Pfeifer, based on analysis by Philippe Blain
          <bledp@voila.fr>)).
        + change renaming of dft_fgbg.3x to use_default_colors.3ncurses in
          man_db.renames, since Debian is not concerned with 14-character
          filename limitation (from Debian bug report by Josip Rodin
          <joy@cibalia.gkvk.hr>).
        + corrected scoansi terminfo entry by testing with scoterm and console.
        + revert change from 990614 to terminal_interface-curses-forms.ads.m4,
          since this does not work for gnat 3.10p
        + modify tclock example to be resizable (if ncurses' sigwinch handler
          is used), and in color.
        + use $(CC) rather than 'gcc' in MK_SHARED_LIB symbols, used for Linux
          shared library rules.

990925  pre-release
        + add newer NetBSD console terminfo entries
        + add amiga-8bit terminfo entry (from Henning 'Faroul' Peters
          <Faroul@beyond.kn-bremen.de>)
        + remove -lcurses -ltermcap from configure script's check for the gpm
          library, since they are not really necessary (a properly configured
          gpm library has no dependency on any curses library), and if the
          curses library is not installed, this would cause the test to fail.
        + modify tic's -C option so that terminfo "use=" clauses are translated
          to "tc=" clauses even when running it as captoinfo.
        + modify CF_STDCPP_LIBRARY configure macro to perform its check only
          for GNU C++, since that library conflicts with SGI's libC on IRIX-6.2
        + modify CF_SHARED_OPTS configure macro to support build on NetBSD with
          ELF libraries (patch by Bernd Ernesti <bernd@arresum.inka.de>).
        + correct a problem in libpanel, where the _nc_top_panel variable was
          not set properly when bottom_panel() is called to hide a panel which
          is the only one on the stack (report/analysis by Michael Andres
          <ma@suse.de>, patch by Juergen Pfeifer).

990918  pre-release
        + add acsc string to HP 70092 terminfo entry (patch by Joerg Wunsch
          <j@interface-business.de>).
        + add top-level uninstall.data and uninstall.man makefile rules.
        + correct logic of CF_LINK_FUNCS configure script, from BeOS changes so
          that hard-links work on Unix again.
        + change default value of cf_cv_builtin_bool to 1 as suggested by
          Jeremy Buhler, making it less likely that a conflicting declaration
          of bool will be seen when compiling with C++.

990911  pre-release
        + improved configure checks for builtin.h
        + minor changes to C++ binding (remove static initializations, and make
          configure-test for parameter initializations) for features not
          allowed by vendor's C++ compilers (reported by Martin Mokrejs, this
          applies to SGI, though I found SCO has the same characteristics).
        + corrected quoting of ETIP_xxx definitions which support old versions
          of g++, e.g., those using -lg++
        + remove 'L' code from safe_sprintf.c, since 'long double' is not
          widely portable.  safe_sprintf.c is experimental, however, and
          exists mainly as a fallback for systems without snprintf (reported
          by Martin Mokrejs <mmokrejs@natur.cuni.cz>, for IRIX 6.2)
        + modify definition of _nc_tinfo_fkeys in broken-linker configuration
          so that it is not unnecessarily made extern (Jeffrey C Honig).

990904  pre-release
        + move definition for builtin.h in configure tests to specific check
          for libg++, since qt uses the same filename incompatibly.
        + correct logic of lib_termcap.c tgetstr function, which did not copy
          the result to the buffer parameter.  Testing shows Solaris does
          update this, though of course tgetent's buffer is untouched (from
          mpc.lists.freebsd.current newsgroup item by Peter Edwards
          <peter.edwards@ireland.com>).
        + corrected beterm terminfo entry, which lists some capabilities which
          are not actually provided by the BeOS Terminal.
        + add special logic to replace select() calls on BeOS, whose select()
          function works only for sockets.
        + correct missing escape in mkterm.h.awk.in, which caused part
          of the copyright noticed to be omitted (reported by Peter
          Wemm <peter@netplex.com.au>).
        > several small changes to make the c++ binding and demo work on OS/2
          EMX (related to a clean reinstall of EMX):
        + correct library-prefix for c++ binding; none is needed.
        + add $x suffix to make_hash and make_keys so 'make distclean' works.
        + correct missing $x suffix for tack, c++ demo executables.
        + split CF_CXX_LIBRARY into CF_GPP_LIBRARY (for -lg++) and
          CF_STDCPP_LIBRARY (for -lstdc++)

990828  pre-release
        + add cygwin terminfo entry -TD
        + modify CF_PROG_EXT configure macro to set .exe extension for cygwin.
        + add configure option --without-cxx-binding, modifying the existing
          --without-cxx option to check only for the C++ compiler
          characteristics.  Whether or not the C++ binding is needed, the
          configure script checks for the size/type of bool, to make ncurses
          match.  Otherwise C++ applications cannot use ncurses.

990821  pre-release
        + updated configure macros CF_MAKEFLAGS, CF_CHECK_ERRNO
        + minor corrections to beterm terminfo entry.
        + modify lib_setup.c to reject values of $TERM which have a '/' in
          them.
        + add ifdef's to guard against CS5, CS6, CS7, CS8 being zero, as more
          than one is on BeOS.  That would break a switch statement.
        + add configure macro CF_LINK_FUNCS to detect and work around BeOS's
          nonfunctional link().
        + improved configure macros CF_BOOL_DECL and CF_BOOL_SIZE to detect
          BeOS's bool, which is declared as an unsigned char.

990814  pre-release
        + add ms-vt100 terminfo entry -TD
        + minor fixes for misc/emx.src, based on testing with tack.
        + minor fix for test/ncurses.c, test 'a', in case ncv is not set.

990731  pre-release
        + minor correction for 'screen' terminfo entry.
        + clarify description of errret values for setupterm in manpage.
        + modify tput to allow it to emit capabilities for hardcopy terminals
          (patch by Goran Uddeborg <goeran@uddeborg.pp.se>).
        + modify the 'o' (panel) test in ncurses.c to show the panels in color
          or at least in bold, to test Juergen's change to wrefresh().
        > patches by Juergen Pfeifer:
        + Fixes a problem using wbkgdset() with panels.  It has actually
          nothing to with panels but is a problem in the implementation of
          wrefresh().  Whenever a window changes its background attribute to
          something different than newscr's background attribute, the whole
          window is touched to force a copy to newscr.  This is an unwanted
          side-effect of wrefresh() and it is actually not necessary.  A
          changed background attribute affects only further outputs of
          background it doesn't mean anything to the current content of the
          window.  So there is no need to force a copy.  (reported by Frank
          Heckenbach <frank@g-n-u.de>).
        + an upward compatible enhancement of the NCursesPad class in the C++
          binding.  It allows one to add a "viewport" window to a pad and then
          to use panning to view the pad through the viewport window.

990724  pre-release
        + suppress a call to def_prog_mode() in the SIGTSTP handler if the
          signal was received while not in curses mode, e.g., endwin() was
          called in preparation for spawning a shell command (reported by Frank
          Heckenbach <frank@g-n-u.de>)
        + corrected/enhanced xterm-r5, xterm+sl, xterm+sl-twm terminfo entries.
        + change test for xterm mouse capability:  it now checks only if the
          user's $DISPLAY variable is set in conjunction with the kmous
          capability being present in the terminfo.  Before, it checked if any
          of "xterm", "rxvt" or "kterm" were substrings of the terminal name.
          However, some emulators which are incompatible with xterm in other
          ways do support the xterm mouse capability.
        + reviewed and made minor changes in ncurses to quiet g++ warnings
          about shadowed or uninitialized variables.  g++ incorrectly warns
          about uninitialized variables because it does not take into account
          short-circuit expression evaluation.
        + change ncurses 'b' test to start in color pair 0 and to show in the
          right margin those attributes which are suppressed by no_color_video,
          i.e., "(NCV)".
        + modify ifdef's in curses.h so that __attribute__ is not redefined
          when compiling with g++, but instead disabled the macros derived for
          __attribute__ since g++ does not consistently recognize the same
          keywords as gcc (reported by Stephan K Zitz <zitz@erf.net>).
        + update dependencies for term.h in ncurses/modules (reported by
          Ilya Zakharevich).

990710  pre-release
        + modify the form demo in ncurses.c to illustrate how to manipulate the
          field appearance, e.g, for highlighting or translating the field
          contents.
        + correct logic in write_entry from split-out of home_terminfo in
          980919, which prevented update of $HOME/.terminfo (reported by Philip
          Spencer <pspencer@fields.utoronto.ca>).

990703  pre-release
        + modify linux terminfo description to make use of kernel 2.2.x mods
          that support cursor style, e.g., to implement cvvis (patch by Frank
          Heckenbach <frank@g-n-u.de>)
        + add special-case in setupterm to retain previously-saved terminal
          settings in cur_term, which happens when curses and termcap calls are
          mixed (from report by Bjorn Helgaas <helgaas@dhc.net>).
        + suppress initialization of key-tries in _nc_keypad() if we are only
          disabling keypad mode, e.g., in endwin() called when keypad() was
          not.
        + modify the Ada95 makefile to ensure that always the Ada files from
          the development tree are used for building and not the eventually
          installed ones (patch by Juergen Pfeifer).

990626  pre-release
        + use TTY definition in tack/sysdep.c rather than struct termios
          (reported by Philippe De Muyter).
        + add a fallback for strstr, used in lib_mvcur.c and tack/edit.c,
          not present on sysV68 (reported by Philippe De Muyter).
        + correct definition in comp_hash.c to build with configure
          --with-rcs-ids option.

990619  pre-release
        + modified ifdef's for sigaction and sigvec to ensure we do not try to
          handle SIGTSTP if neither is available (from report by Philippe De
          Muyter).
        > patch by Philippe De Muyter:
        + in tic.c, use `unlink' if `remove' is not available.
        + use only `unsigned' as fallback value for `speed_t'.  Some files used
          `short' instead.

990616  pre-release
        + fix some compiler warnings in tack.
        + add a check for predefined bool type in CC, based on report that
          BeOS predefines a bool type.
        + correct logic for infocmp -e option (i.e., the configure
          --with-fallbacks option), which I'd not updated when implementing
          extended names (cf:  990301).  The new implementation adds a -E
          option to infocmp.
        > patch by Juergen Pfeifer:
        + introduce the private type Curses_Bool in the Ada95 binding
          implementation.  This is to clearly represent the use of "bool" also
          in the binding.  It should have no effect on the generated code.
        + improve the man page for field_buffer() to tell the people, that the
          whole buffer including leading/trailing spaces is returned.  This is
          a common source of confusion, so it's better to document it clearly.

990614  pre-release
        > patch by Juergen Pfeifer:
        + use pragma PreElaborate in several places.
        + change a few System.Address uses to more specific types.
        + change interface version-number to 1.0
        + regenerate Ada95 HTML files.

990612  pre-release
        + modify lib_endwin.c to avoid calling reset_shell_mode(), return ERR
          if it appears that curses was never initialized, e.g., by initscr().
          For instance, this guards against setting the terminal modes to
          strange values if endwin() is called after setupterm().  In the same
          context, Solaris curses will dump core.
        + modify logic that avoids a conflict in lib_vidattr.c between sgr0 and
          equivalent values in rmso or rmul by ensuring we do not modify the
          data which would be returned by the terminfo or termcap interfaces
          (reported by Brad Pepers <brad@linuxcanada.com>, cf:  960706).
        + add a null-pointer check for SP in lib_vidattr.c to logic that checks
          for magic cookies.
        + improve fallback declaration of 'bool' when the --without-cxx option
          is given, by using a 'char' on i386 and related hosts (from
          discussion with Alexander Lukyanov).

990605  pre-release
        + include time.h in lib_napms.c if nanosleep is used (patch by
          R Lindsay Todd <toddr@rpi.edu>).
        + add an "#undef bool" to curses.h, in case someone tries to define it,
          e.g., perl.
        + add check to tparm to guard against divide by zero (reported by Aaron
          Campbell <aaron@ug.cs.dal.ca>).

990516  pre-release
        + minor fix to build tack on CLIX (mismatched const).
        > patch by Juergen Pfeifer:
        + change Juergen's old email address with new one in the files where it
          is referenced.  The Ada95 HTML pages are regenerated.
        + update MANIFEST to list the tack files.

990509  pre-release
        + minor fixes to make 'tack' build/link on NeXT (reported by Francisco
          A. Tomei Torres).

990417  pre-release
        + add 'tack' program (which is GPL'd), updating it to work with the
          modified TERMTYPE struct and making a fix to support setaf/setab
          capabilities.  Note that the tack program is not part of the
          ncurses libraries, but an application which can be distributed with
          ncurses.  The configure script will ignore the directory if it is
          omitted, however.
        + modify gpm mouse support so that buttons 2 and 3 are used for
          select/paste only when shift key is pressed, making them available
          for use by an application (patch by Klaus Weide).
        + add complete list of function keys to scoansi terminfo entry - TD

990410  pre-release
        + add a simple test program cardfile.c to illustrate how to read form
          fields, and showing forms within panels.
        + change shared-library versioning for the Hurd to be like Linux rather
          than *BSD (patch by Mark Kettenis <kettenis@wins.uva.nl>).
        + add linux-lat terminfo entry.
        + back-out _nc_access check in read_termcap.c (both incorrect and
          unnecessary, except to guard against a small window where the file's
          ownership may change).

990403  pre-release
        + remove conflicting _nc_free_termtype() function from test module
          lib_freeall.c
        + use _nc_access check in read_termcap.c for termpaths[] array (noted
          by Jeremy Buhler, indicating that Alan Cox made a similar patch).
        > patch by Juergen Pfeifer:
        + modify menu creation to not inherit status flag from the default menu
          which says that the associated marker string has been allocated and
          should be freed (bug reported by Marek Paliwoda"
          <paliwoda@kki.net.pl>)

990327  pre-release (alpha.gnu.org:/gnu/ncurses-5.0-beta1.tar.gz)
        + minor fixes to xterm-xfree86 terminfo entry - TD.
        + split up an expression in configure script check for ldconfig to
          workaround limitation of BSD/OS sh (reported by Jeff Haas
          <jmh@mail.msen.com>).
        + correct a typo in man/form_hook.3x (Todd C Miller).

990318  pre-release
        + parenthesize and undef 'index' symbol in c++ binding and demo, to
          accommodate its definition on NeXT (reported by Francisco A. Tomei
          Torres).
        + add sigismember() to base/sigaction.c compatibility to link on NeXT
          (reported by Francisco A. Tomei Torres).
        + further refinements to inequality in hashmap.c to cover a case with
          ^U in nvi (patch by Alexander Lukyanov).

990316  pre-release
        + add fallback definition for getcwd, to link on NeXT.
        + add a copy of cur_term to tic.c to make it link properly on NeXT
          (reported by Francisco A. Tomei Torres).
        + change inequality in hashmap.c which checks the distance traveled by
          a chunk so that ^D command in nvi (scrolls 1/2 screen) will use
          scrolling logic (patch by Alexander Lukyanov, reported by Jeffrey
          C Honig).

990314  pre-release
        + modify lib_color.c to handle a special case where the curscr
          attributes have been made obsolete (patch by Alexander Lukyanov).
        + update BSD/OS console terminfo entries to use klone+sgr and
          klone+color (patch by Jeffrey C Honig).
        + update glibc addon configure script for extended capabilities.
        + correct a couple of warnings in the --enable-const configuration.
        + make comp_hash build properly with _nc_strdup(), on NeXT (reported by
          Francisco A. Tomei Torres <francisco.tomei@cwix.com>).

990313  pre-release
        + correct typos in linux-c initc string - TD
        + add 'crt' terminfo entry, update xterm-xfree86 entry - TD
        + remove a spurious argument to tparm() in lib_sklrefr.c (patch by
          Alexander Lukyanov).

990307  pre-release
        + back-out change to wgetch because it causes a problem with ^Z
          handling in lynx (reported by Kim DeVaughn).

990306  pre-release
        + add -G option to tic and infocmp, to reverse the -g option.
        + recode functions in name_match.c to avoid use of strncpy, which
          caused a 4-fold slowdown in tic (cf: 980530).
        + correct a few warnings about sign-extension in recent changes.
        > patch by Juergen Pfeifer:
        + fixes suggested by Jeff Bradbury <jibradbury@lucent.com>:
          + improved parameter checking in new_fieldtype().
          + fixed a typo in wgetch() timeout handling.
          + allow slk_init() to be called per newterm call.  The internal SLK
            state is stored in the SCREEN struct after every newterm() and then
            reset for the next newterm.
          + fix the problem that a slk_refresh() refreshes stdscr if the
            terminal has true SLKs.
        + update HTML documentation for Ada binding.

990301  pre-release
        + remove 'bool' casts from definitions of TRUE/FALSE so that statements
          such as "#if TRUE" work.  This was originally done to allow for a C++
          compiler which would warn of implicit conversions between enum and
          int, but is not needed for g++ (reported by Kim DeVaughn).
        + add use_extended_names() function to allow applications to suppress
          read of the extended capabilities.
        + add configure option --enable-tcap-names to support logic which
          allows ncurses' tic to define new (i.e., extended) terminal
          capabilities.  This is activated by the tic -x switch.  The infocmp
          program automatically shows or compares extended capabilities.
          Note:  This changes the Strings and similar arrays in the TERMTYPE
          struct so that applications which manipulate it must be recompiled.
        + use macros typeMalloc, typeCalloc and typeRealloc consistently
          throughout ncurses library.
        + add _nc_strdup() to doalloc.c.
        + modify define_key() to allow multiple strings to be bound to the
          same keycode.
        + correct logic error in _nc_remove_string, from 990220.
        > patch by Juergen Pfeifer, for Ada95 binding:
        + regenerate some of the html documentation
        + minor cleanup in terminal_interface-curses.adb

990220  pre-release
        + resolve ambiguity of kend/kll/kslt and khome/kfnd/kich1 strings in
          xterm and ncsa terminfo entries by removing the unneeded ones.  Note
          that some entries will return kend & khome versus kslt and kfnd, for
          PC-style keyboards versus strict vt220 compatiblity - TD
        + add function keybound(), which returns the definition associated with
          a given keycode.
        + modify define_key() to undefine the given string when no keycode is
          given.
        + modify keyok() so it works properly if there is more than one string
          defined for a keycode.
        + add check to tic to warn about terminfo descriptions that contain
          more than one key assigned to the same string.  This is shown only if
          the verbose (-v) option is given.  Moved related logic (tic -v) from
          comp_parse.c into the tic program.
        + add/use _nc_trace_tries() to show the function keys that will be
          recognized.
        + rename init_acs to _nc_init_acs (request by Alexander Lukyanov).
        > patch by Juergen Pfeifer, for Ada95 binding:
        + remove all the *_adabind.c from ncurses, menu and form projects.
          Those little helper routines have all been implemented in Ada and are
          no longer required.
        + The option handling routines in menu and form have been made more
          save.  They now make sure that the unused bits in options are always
          zero.
        + modify configuration scripts to
          + use gnatmake as default compiler name.  This is a safer choice than
            gcc, because some GNAT implementations use other names for the
            compilerdriver to avoid conflicts.
          + use new default installation locations for the Ada files according
            to the proposed GNU Ada filesystem standard (for Linux).
        + simplify the Makefiles for the Ada binding
        + rename ada_include directory to src.

990213
        + enable sigwinch handler by default.
        + disable logic that allows setbuf to be turned off/on, because some
          implementations will overrun the buffer after it has been disabled
          once.

990206
        + suppress sc/rc capabilities from terminal description if they appear
          in smcup/rmcup.  This affects only scrolling optimization, to fix a
          problem reported by several people with xterm's alternate screen,
          though the problem is more general.
        > patch by Juergen Pfeifer, for Ada95 binding:
        + removed all pragma Preelaborate() stuff, because the just released
          gnat-3.11p complains on some constructs.
        + fixed some upper/lower case notations because gnat-3.11p found
          inconsistent use.
        + used a new method to generate the HTML documentation of the Ada95
          binding.  This invalidates nearly the whole ./Ada95/html subtree.
          Nearly all current files in this subtree are removed

990130
        + cache last result from _nc_baudrate, for performance (suggested by
          Alexander Lukyanov).
        + modify ClrUpdate() function to workaround a problem in nvi, which
          uses redrawwin in SIGTSTP handling.  Jeffrey C Honig reported that
          ncurses repainted the screen with nulls before resuming normal
          operation (patch by Alexander Lukyanov).
        + generalize is_xterm() function a little by letting xterm/rxvt/kterm
          be any substring rather than the prefix.
        + modify lib_data.c to initialize SP.  Some linkers, e.g., IBM's, will
          not link a module if the only symbols exported from the module are
          uninitialized ones (patch by Ilya Zakharevich, who says that he has
          seen messages claiming this behaviour conforms to the standard.)
        + move call on _nc_signal_handler past _nc_initscr, to avoid a small
          window where Nttyb hasn't yet been filled (reported by Klaus Weide).
        + modify lib_tstp.c to block SIGTTOU when handling SIGTSTP, fixes a
          problem where ncurses applications which were run via a shell script
          would hang when given a ^Z.  Also, check if the terminal's process
          group is consistent, i.e., a shell has not taken ownership of it,
          before deciding to save the current terminal settings in the SIGTSTP
          handler (patch by Klaus Weide).
        + correct spelling of ACS_ names in curs_border.3x (reported by Bob van
          der Poel <bvdpoel@kootenay.com>).
        + correct a couple of typos in the macros supporting the configure
          --with-shlib-version option.

990123
        + modify fty_regex.c to compile on HAVE_REGEXPR_H_FUNCS machine (patch
          by Kimio Ishii <ishii@csl.sony.co.jp>).
        + rename BSDI console terminfo entries:  bsdos to bsdos-pc-nobold, and
          bsdos-bold to bsdos-pc (patch by Jeffrey C Honig).
        + modify tput to accept termcap names as an alternative to terminfo
          names (patch by Jeffrey C Honig).
        + correct a typo in term.7 (Todd C Miller).
        + add configure --with-shlib-version option to allow installing shared
          libraries named according to release or ABI versions.  This
          parameterizes some existing logic in the configure script, and is
          intended for compatiblity upgrades on Digital Unix, which used
          versioned libraries in ncurses 4.2, but no longer does (cf:  980425).
        + resync configure script against autoconf 2.13 + patches
        + minor improvements for teraterm terminfo entry based on the program's
          source distribution.

990116
        + change default for configure --enable-big-core to assume machines do
          have enough memory to resolve terminfo.src in-memory.
        + correct name of ncurses library in TEST_ARGS when configuring with
          debug library.
        + minor fixes to compile ncurses library with broken-linker with g++.
        + add --enable-broken-linker configure option, default to environment
          variable $BROKEN_LINKER (request by Jeffrey C Honig).
        + change key_names[] array to static since it is not part of the curses
          interface (reported by Jeffrey C Honig <jch@bsdi.com>).

990110
        + add Tera Term terminfo entry - TD

990109
        + reviewed/corrected macros in curses.h as per XSI document.
        + provide support for termcap PC variable by copying it from terminfo
          data and using it as the padding character in tputs (reported by
          Alexander Lukyanov).
        + corrected iris-ansi and iris-ansi-ap terminfo entries for kent and
          kf9-kf12 capabilities, as well as adding kcbt.
        + document the mouse handling mechanism in menu_driver and make a small
          change in menu_driver's return codes to provide more consistency
          (patch by Juergen Pfeifer).
        + add fallback definition for NCURSES_CONST to termcap.h.in (reported
          by Uchiyama Yasushi <uch@nop.or.jp>).
        + move lib_restart.c to ncurses/base, since it uses curses functions
          directly, and therefore cannot be used in libtinfo.so
        + rename micro_char_size to micro_col_size, adding #define to retain
          old name.
        + add set_a_attributes and set_pglen_inch to terminfo structure, as per
          XSI and Solaris 2.5.
        + minor makefile files to build ncurses test_progs
        + update html files in misc directory to reflect changes since 4.2

990102
        + disable scroll hints when hashmap is enabled (patch by Alexander
          Lukyanov).
        + move logic for tic's verify of -e option versus -I and -C so that the
          terminfo data is not processed if we cannot handle -e (reported by
          Steven Schwartz <steves@unitrends.com>.
        + add test-driver traces to terminfo and termcap functions.
        + provide support for termcap ospeed variable by copying it from the
          internal cur_term member, and using ospeed as the baudrate reference
          for the delay_output and tputs functions.  If an application does not
          set ospeed, the library behaves as before, except that _nc_timed_wait
          is no longer used, or needed, since ospeed always has a value.  But
          the application can modify ospeed to adjust the output of padding
          characters (from a bug report for screen 3.7.6 and email from Michael
          Schroeder <Michael.Schroeder@informatik.uni-erlangen.de>).
        + removed some unused ifdef's as part of Alexander's restructuring.
        + reviewed/updated curses.h, term.h against X/Open Curses Issue 4
          Version 2.  This includes making some parameters NCURSES_CONST
          rather than const, e.g., in termcap.h.
        + change linux terminfo entry to use ncv#2, since underline does not
          work with color

981226
        + miscellaneous corrections for curses.h to match XSI.
        + change --enable-no-padding configure option to be normally enabled.
        + add section to ncurses manpage for environment variables.
        + investigated Debian bug report that pertains to screen 3.7.4/3.7.6
          changes, found no sign of problems on Linux (or on SunOS, Solaris)
          running screen built with ncurses.
        + check if tmp_fp is opened in tic.c before closing it (patch by Pavel
          Roskin <pavel_roskin@geocities.com>).
        + correct several font specification typos in man-pages.

981220
        + correct default value for BUILD_CC (reported by Larry Virden).

981219
        + modify _nc_set_writedir() to set a flag in _nc_tic_dir() to prevent
          it from changing the terminfo directory after chdir'ing to it.
          Otherwise, a relative path in $TERMINFO would confuse tic (from a
          Debian bug report).
        + correct/update ncsa terminfo entry (report by Larry Virden).
        + update xterm-xfree86 terminfo to current (patch 90), smcur/rmcur
          changes
        + add Mathew Vernon's mach console entries to terminfo.src
        + more changes, moving functions, as part of Alexander's restructuring.
        + modify configure script for GNU/Hurd share-library support, introduce
          BUILD_CC variable for cross compiling (patch by Uchiyama Yasushi
          <uch@nop.or.jp>)

981212
        + add environment variable NCURSES_NO_SETBUF to allow disabling the
          setbuf feature, for testing purposes.
        + correct ifdef's for termcap.h versus term.h that suppress redundant
          declarations of prototypes (reported by H.J.Lu).
        + modify Makefile.os2 to add linker flags which allow multiple copies
          of an application to coexist (reported by Ilya Zakharevich).
        + update Makefile.glibc and associated configure script so that ncurses
          builds as a glibc add-on with the new directory configuration
          (reported by H.J.Lu).

981205
        + modify gen_reps() function in gen.c to work properly on SunOS
          (sparc), which is a left-to-right architecture.
        + modify relative_move and tputs to avoid an interaction with the
          BSD-style padding.  The relative_move function could produce a string
          to replace on the screen which began with a numeric character, which
          was then interpreted by tputs as padding.  Now relative_move will not
          generate a string with a leading digit in that case (overwrite).
          Also, tputs will only interpret padding if the string begins with a
          digit; as coded it permitted a string to begin with a decimal point
          or asterisk (reported by Larry Virden).
        > patches by Juergen Pfeifer:
        + fix a typo in m_driver.c mouse handling and improves the error
          handling.
        + fix broken mouse handling in the Ada95 binding
        + make the Ada95 sample application menus work with the new menu mouse
          support
        + improve the mouse handling introduced by Ilya; it now handles menus
          with spacing.
        + repair a minor bug in the menu_driver code discovered during this
          rework.
        + add new function wmouse_trafo() to hide implementation details of
          _yoffset member of WINDOW struct needed for mouse coordinate
          transformation.

981128
        + modify Ada95/gen/gen.c to avoid using return-value of sprintf, since
          some older implementations (e.g., SunOS 4.x) return the buffer
          address rather than its length.
        > patch by Rick Ohnemus:
        + modify demo.cc to get it to compile with newer versions of egcs.
        + trim a space that appears at the end of the table preprocessor lines
          ('\" t).  This space prevents some versions of man from displaying
          the pages - changed to remove all trailing whitespace (TD)
        + finally, 'make clean' does not remove panel objects.
        > patches by Ilya Zakharevich:
        + allow remapping of OS/2 mouse buttons using environment variable
          MOUSE_BUTTONS_123 with the default value 132.
        + add mouse support to ncurses menus.

981121
        + modify misc/makedef.cmd to report old-style .def file symbols, and to
          generate the .def files sorted by increasing names rather than the
          reverse.
        + add misc/*.ref which are J.J.G.Ripoll's dll definition files (renamed
          from misc/*.old), and updated based on the entrypoint coding he used
          for an older version of ncurses.
        + add README.emx, to document how to build on OS/2 EMX.
        + updates for config.guess, config.sub from Lynx
        > patches by Ilya Zakharevich:
        + minor fixes for mouse handling mode:
          a) Do not initialize mouse if the request is to have no mouse;
          b) Allow switching of OS/2 VIO mouse on and off.
        + modify Makefile.os2 to support alternative means of generating
          configure script, by translating Unix script with Perl.
        > patches by Juergen Pfeifer:
        + Updates MANIFEST to reflect changes in source structure
        + Eliminates a problem introduced with my last patch for the C++
          binding in the panels code.  It removes the update() call done in the
          panel destructor.
        + Changes in the Ada95 binding to better support systems where
          sizeof(chtype)!=sizeof(int) (e.g.  DEC Alpha).

981114
        + modify install-script for manpages to skip over .orig and .rej files
          (request by Larry Virden).
        > patches/discussion by Alexander Lukyanov:
        + move base-library sources into ncurses/base and tty (serial terminal)
          sources into ncurses/tty, as part of Alexander Lukyanov's proposed
          changes to ncurses library.
        + copy _tracemouse() into ncurses.c so that lib_tracemse.c need not
          be linked into the normal ncurses library.
        + move macro winch to a function, to hide details of struct ldat
        > patches by Juergen Pfeifer:
        + fix a potential compile problem in cursesw.cc
        + some Ada95 cosmetics
        + fix a gen.c problem when compiling on 64-Bit machines
        + fix Ada95/gen/Makefile.in "-L" linker switch
        + modify Ada95 makefiles to use the INSTALL_PREFIX setting.

981107
        + ifdef'd out lib_freeall.c when not configured.
        + rename _tracebits() to _nc_tracebits().
        + move terminfo-library sources into ncurses/tinfo, and trace-support
          functions into ncurses/trace as part of Alexander Lukyanov's proposed
          changes to ncurses library.
        + modify generated term.h to always specify its own definitions for
          HAVE_TERMIOS_H, etc., to guard against inclusion by programs with
          broken configure scripts.

981031
        + modify terminfo parsing to accept octal and hexadecimal constants,
          like Solaris.
        + remove an autoconf 2.10 artifact from the configure script's check
          for "-g" compiler options.  (Though harmless, this confused someone
          at Debian, who recently issued a patch that results in the opposite
          effect).
        + add configure option --with-ada-compiler to accommodate installations
          that do not use gcc as the driver for GNAT (patch by Juergen
          Pfeifer).

981017
        + ensure ./man exists in configure script, needed when configuring
          with --srcdir option.
        + modify infocmp "-r" option to remove limit on formatted termcap
          output, which makes it more like Solaris' version.
        + modify captoinfo to treat no-argument case more like Solaris'
          version, which uses the contents of $TERMCAP as the entry to format.
        + modify mk-2nd.awk to handle subdirectories, e.g., ncurses/tty
          (patch by Alexander V Lukyanov).

981010
        + modify --with-terminfo-dirs option so that the default value is the
          ${datadir} value, unless $TERMINFO_DIRS is already set.  This gets
          rid of a hardcoded list of candidate directories in the configure
          script.
        + add some error-checking to _nc_read_file_entry() to ensure that
          strings are properly terminated (Todd C Miller).
        + rename manpage file curs_scr_dmp.3x to curs_scr_dump.3x, to
          correspond with contents (reported by Neil Zanella
          <nzanella@cs.mun.ca>).
        + remove redundant configure check for C++ which did not work when $CXX
          was specified with a full pathname (reported by Andreas Jaeger).
        + corrected bcopy/memmove check; the macro was not standalone.

981003
        + remove unnecessary portion of OS/2 EMX mouse change from
          check_pending() (reported by Alexander V Lukyanov).

980926
        + implement mouse support for OS/2 EMX (adapted from patch against
          4.2(?) by Ilya Zakharevich).
        + add configure-check for bcopy/memmove, for 980919 changes to hashmap.
        + merge Data General terminfo from Hasufin <hasufin@vidnet.net> - TD
        + merge AIX 3.2.5 terminfo descriptions for IBM terminals, replaces
          some older entries - TD
        + modify tic to compile into %'char' form in preference to %{number},
          since that is a little more efficient.
        + minor correction to infocmp to avoid displaying "difference" between
          two capabilities that are rendered in equivalent forms.
        + add -g option to tic/infocmp to force character constants to be
          displayed in quoted form.  Otherwise their decimal values are shown.
        + modify setupterm so that cancelled strings are treated the same as
          absent strings, cancelled and absent booleans false (does not affect
          tic, infocmp).
        + modify tic, infocmp to discard redundant i3, r3 strings when output
          to termcap format.
        > patch by Alexander V Lukyanov:
        + improve performance of tparm, now it takes 19% instead of 25% when
          profiling worm.
        + rename maxlen/minlen to prec/width for better readability.
        + use format string for printing strings.
        + use len argument correctly in save_text, and pass it to save_number.

980919
        + make test_progs compile (but hashmap does not function).
        + correct NC_BUFFERED macro, used in lib_mvcur test-driver, modify
          associated logic to avoid freeing the SP->_setbuf data.
        + add modules home_terminfo and getenv_num to libtinfo.
        + move write_entry to libtinfo, to work with termcap caching.
        + minor fixes to blue.c to build with atac.
        + remove softscroll.c module; no longer needed for testing.
        > patches by Todd C Miller:
        + use strtol(3) instead of atoi(3) when parsing env variables so we can
          detect a bogus (non-numeric) value.
        + check for terminal names > MAX_NAME_SIZE in a few more places when
          dealing with env variables again.
        + fix a MAX_NAME_SIZE that should be MAX_NAME_SIZE+1
        + use sizeof instead of strlen(3) on PRIVATE_INFO since it is a fixed
          string #define (compile time vs runtime).
        + when setting errno to ENOMEM, set it right before the return, not
          before code that could, possibly, set errno to a different value.
        > patches by Alexander V Lukyanov:
        + use default background in update_cost_from_blank()
        + disable scroll-hints when hashmap is configured.
        + improve integration of hashmap scrolling code, by adding oldhash and
          newhash data to SP struct.
        + invoke del_curterm from delscreen.
        + modify del_curterm to set cur_term to null if it matches the
          function's parameter which is deleted.
        + modify lib_doupdate to prefer parm_ich to the enter_insert_mode and
          exit_insert_mode combination, adjusting InsCharCost to check
          enter_insert_mode, exit_insert_mode and insert_padding.  Add
          insert_padding in insert mode after each char.  This adds new costs
          to the SP struct.

980912
        + modify test-driver in lib_mvcur.s to use _nc_setbuffer, for
          consistent treatment.
        + modify ncurses to restore output to unbuffered on endwin, and resume
          buffering in refresh (see lib_set_term.c and NC_BUFFERED macro).
        + corrected HTML version numbers (according to the W3C validator, they
          never were HTML 2.0-compliant, but are acceptable 3.0).

980905
        + modify MKterminfo.sh to generate terminfo.5 with tables sorted by
          capability name, as in SVr4.
        + modified term.h, termcap.h headers to avoid redundant declarations.
        + change 'u_int' type in tset.c to unsigned, making this compile on
          Sequent PRX 4.1 (reported by Michael Sterrett <msterret@coat.com>).

980829
        + corrections to mailing addresses, and moving the magic line that
          causes the man program to invoke tbl to the first line of each
          manpage (patch by Rick Ohnemus <rick@ecompcon.com>).
        + add Makefile.os2 and supporting scripts to generate dll's on OS/2 EMX
          (from J.J.G.Ripoll, with further integration by TD).
        + correct a typo in icl6404 terminfo entry.
        + add xtermm and xtermc terminfo entries.
        > from esr's terminfo version:
        + Added Francesco Potorti's tuned Wyse 99 entries.
        + dtterm enacs correction from Alexander V Lukyanov.
        + Add ncsa-ns, ncsa-m-ns and ncsa-m entries from esr version.

980822
        + document AT&T acs characters in terminfo.5 manpage.
        + use EMX _scrsize() function if terminfo and environment do not
          declare the screen size (reported by Ilya Zakharevich
          <ilya@math.ohio-state.edu>).
        + remove spurious '\' characters from eterm and osborne terminfo
          entries (prompted by an old Debian bug report).
        + correct reversed malloc/realloc calls in _nc_doalloc (reported by
          Hans-Joachim Widmaier <hjwidmai@foxboro.com>).
        + correct misplaced parenthesis which caused file-descriptor from
          opening termcap to be lost, from 980725 changes (reported by Andreas
          Jaeger).

980815
        + modify lib_setup.c to eliminate unneeded include of <sys/ioctl.h>
          when termios is not used (patch by Todd C Miller).
        + add function _nc_doalloc, to ensure that failed realloc calls do not
          leak memory (reported by Todd C Miller).
        + improved ncsa-telnet terminfo entry.

980809
        + correct missing braces around a trace statement in read_entry.c,
          from 980808 (reported by Kim DeVaughn <kimdv@best.com> and Liviu
          Daia).

980808
        + fix missing include <errno.h> in ditto.c (reported by Bernhard
          Rosenkraenzer <bero@k5.sucks.eu.org>)
        + add NCSA telnet terminfo entries from Francesco Potorti
          <F.Potorti@cnuce.cnr.it>, from Debian bug reports.
        + make handling of $LINES and $COLUMNS variables more compatible with
          Solaris by allowing them to individually override the window size
          as obtained via ioctl.

980801
        + modify lib_vidattr.c to allow for terminal types (e.g., xterm-color)
          which may reset all attributes in the 'op' capability, so that colors
          are set before turning on bold and other attributes, but still after
          turning attributes off.
        + add 'ditto.c' to test directory to illustrate use of newterm for
          initializing multiple screens.
        + modify _nc_write_entry() to recover from failed attempt to link alias
          for a terminfo on a filesystem which does not preserve character case
          (reported by Peter L Jordan <PJordan@chla.usc.edu>).

980725
        + updated versions of config.guess and config.sub based on automake 1.3
        + change name-comparisons in lib_termcap to compare no more than 2
          characters (gleaned from Debian distribution of 1.9.9g-8.8, verified
          with Solaris curses).
        + fix typo in curs_insstr.3x (patch by Todd C Miller)
        + use 'access()' to check if ncurses library should be permitted to
          open or modify files with fopen/open/link/unlink/remove calls, in
          case the calling application is running in setuid mode (request by
          Cristian Gafton <gafton@redhat.com>, responding to Duncan Simpson
          <dps@io.stargate.co.uk>).
        + arm100 terminfo entries from Dave Millen <dmill@globalnet.co.uk>).
        + qnxt2 and minitel terminfo entries from esr's version.

980718
        + use -R option with ldconfig on FreeBSD because otherwise it resets
          the search path to /usr/lib (reported by Dan Nelson).
        + add -soname option when building shared libraries on OpenBSD 2.x
          (request by QingLong).
        + add configure options --with-manpage-format and
          --with-manpage-renames (request by QingLong).
        + correct conversion of CANCELLED_NUMERIC in write_object(), which was
          omitting the high-order byte, producing a 254 in the compiled
          terminfo.
        + modify return-values of tgetflag, tgetnum, tgetstr, tigetflag,
          tigetnum and tigetstr to be compatible with Solaris (gleaned from
          Debian distribution of 1.9.9g-8.8).
        + modify _nc_syserr_abort to abort only when compiled for debugging,
          otherwise simply exit with an error.

980711
        + modify Ada95 'gen' program to use appropriate library suffix (e.g.,
          "_g" for a debug build).
        + update Ada95 'make clean' rule to include generics .ali files
        + add a configure test to ensure that if GNAT is found, that it can
          compile/link working Ada95 program.
        + flush output in beep and flash functions, fixing a problem with
          getstr (patch by Alexander V Lukyanov)
        + fix egcs 1.0.2 warning for etip.h (patch by Chris Johns).
        + correct ifdef/brace nesting in lib_sprintf.c (patch by Bernhard
          Rosenkraenzer <bero@Pool.Informatik.RWTH-Aachen.DE>).
        + correct typo in wattr_get macro from 980509 fixes (patch by Dan
          Nelson).

980704
        + merge changes from current XFree86 xterm terminfo descriptions.
        + add configure option '--without-ada'.
        + add a smart-default for termcap 'ac' to terminfo 'acs_chars' which
          corresponds to vt100.
        + change translation for termcap 'rs' to terminfo 'rs2', which is
          the documented equivalent, rather than 'rs1'.

980627
        + slow 'worm' down a little, for very fast machines.
        + corrected firstchar/lastchar computation in lib_hline.c
        + simplify some expressions with CHANGED_CELL, CHANGED_RANGE and
          CHANGED_TO_EOL macros.
        + modify init_pair so that if a color-pair is reinitialized, we will
          repaint the areas of the screen whose color changes, like SVr4 curses
          (reported by Christian Maurer <maurer@inf.fu-berlin.de>).
        + modify getsyx/setsyx macros to comply with SVr4 man-page which
          says that leaveok() affects their behavior (report by Darryl Miles,
          patch by Alexander V Lukyanov).

980620
        + review terminfo.5 against Solaris 2.6 curses version, corrected
          several minor errors/omissions.
        + implement tparm %l format.
        + implement tparm printf-style width and precision for %s, %d, %x, %o
          as per XSI.
        + implement tparm dynamic variables (reported by Xiaodan Tang).

980613
        + update man-page for for wattr_set, wattr_get (cf:  980509)
        + correct limits in hashtest, which would cause nonprinting characters
          to be written to large screens.
        + correct configure script, when --without-cxx was specified:  the
          wrong variable was used for cf_cv_type_of_bool.  Compilers up to gcc
          2.8 tolerated the missing 'int'.
        + remove the hardcoded name "gcc" for the GNU Ada compiler.  The
          compiler's name might be something like "egcs" (patch by Juergen
          Pfeifer).
        + correct curs_addch.3x, which implied that echochar could directly
          display control characters (patch by Alexander V Lukyanov).
        + fix typos in ncurses-intro.html (patch by Sidik Isani
          <isani@cfht.hawaii.edu>)

980606
        + add configure test for conflicting use of exception in math.h and
          other headers.
        + minor optimization to 'hash()' function in hashmap.c, reduces its
          time by 10%.
        + correct form of LD_SHARED_OPTS for HP-UX 10.x (patch by Tim Mooney).
        + fix missing quotes for 'print' in MKunctrl.awk script (reported by
          Mihai Budiu <mihaib@gs41.sp.cs.cmu.edu>).
        > patch by Alexander V Lukyanov:
        + correct problem on Solaris (with poll() function) where getch could
          hang indefinitely even if timeout(x) was called.  This turned out to
          be because milliseconds was not updated before 'goto retry' in
          _nc_timed_wait.
        + simplified the function _nc_timed_wait and fixed another bug, which
          was the assumption of !GOOD_SELECT && HAVE_GETTIMEOFDAY in *timeleft
          assignment.
        + removed the cycle on EINTR, as it seems to be useless.

980530
        + add makefile-rule for test/keynames
        + modify run_tic.sh and shlib to ensure that user's .profile does not
          override the $PATH used to run tic (patch by Tim Mooney).
        + restore LD_SHARED_OPTS to $(LD_SHARED_FLAGS) when linking programs,
          needed for HP-UX shared-library path (recommended by Tim Mooney).
        + remove special case of HP-UX -L options, use +b options to embed
          $(libdir) in the shared libraries (recommended by Tim Mooney).
        + add checks for some possible buffer overflows and unchecked
          malloc/realloc/calloc/strdup return values (patch by Todd C Miller
          <Todd.Miller@courtesan.com>)

980523
        + correct maxx/maxy expression for num_columns/num_lines in derwin
          (patch by Alexander V Lukyanov).
        + add /usr/share/lib/terminfo and /usr/lib/terminfo as compatibilty
          fallbacks to _nc_read_entry(), along with --with-terminfo-dirs
          configure option (suggested by Mike Hopkirk).
        + modify config.guess to recognize Unixware 2.1 and 7 (patch by Mike
          Hopkirk <hops@sco.com>).
        + suppress definition of CC_SHARED_OPTS in LDFLAGS_SHARED in c++
          Makefile.in, since this conflicts when g++ is used with HP-UX
          compiler (reported by Tim Mooney).
        + parenthesize 'strcpy' calls in c++ binding to workaround redefinition
          in some C++ implementations (reported by several people running
          egcs with glibc 2.0.93, analysis by Andreas Jaeger.

980516
        + modify write_entry.c so that it will not attempt to link aliases
          with embedded '/', but give only a warning.
        + put -L$(libdir) first when linking programs, except for HP-UX.
        + modify comp_scan.c to handle SVr4 terminfo description for att477,
          which contains a colon in the description field.
        + modify configure script to support SCO osr5.0.5 shared libraries
          (from comp.unix.sco.programmer newsgroup item by Mike Hopkirk
          <hops@sco.com>).
        + eliminate extra GoTo call in lib_doupdate.c (patch by Alexander V.
          Lukyanov).
        + minor adjustments of const/NCURSES_CONST from IRIX compile.
        + add updates based on esr's 980509 version of terminfo.src.

980509
        + correct macros for wattr_set, wattr_get, separate wattrset macro from
          these to preserve behavior that allows attributes to be combined with
          color pair numbers.
        + add configure option --enable-no-padding, to allow environment
          variable $NCURSES_NO_PADDING to eliminate non-mandatory padding,
          thereby making terminal emulators (e.g., for vt100) a little more
          efficient (request by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
        + modify configure script to embed ABI in shared libraries for HP-UX
          10.x (detailed request by Tim Mooney).
        + add test/example of the 'filter()' function.
        + add nxterm and xterm-color terminfo description (request by Cristian
          Gafton <gafton@redhat.com>).
        + modify rxvt terminfo description to clear alternate screen before
          switching back to normal screen, for compatibility with applications
          which use xterm (reported by Manoj Kasichainula <manojk@io.com>).
        + modify linux terminfo description to reset color palette (reported
          by Telford Tendys <telford@eng.uts.edu.au>).
        + correction to doupdate, for case where terminal does not support
          insert/delete character.  The logic did not check that there was a
          difference in alignment of changes to old/new screens before
          repainting the whole non-blank portion of the line.  Modified to fall
          through into logic that reduces by the portion which does not differ
          (reported by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
        + minor performance improvement to wnoutrefresh by moving some
          comparisons out of inner loop.

980425
        + modify configure script to substitute NCURSES_CONST in curses.h
        + updated terminfo entries for xterm-xf86-v40, xterm-16color,
          xterm-8bit to correspond to XFree86 3.9Ag.
        + remove restriction that forces ncurses to use setaf/setab if the
          number of colors is greater than 8.  (see 970524 for xterm-16color).
        + change order of -L options (so that $(libdir) is searched first) when
          linking tic and other programs, to workaround HP's linker.
          Otherwise, the -L../lib is embedded when linking against shared
          libraries and the installed program does not run (reported by Ralf
          Hildebrandt).
        + modify configuration of shared libraries on Digital Unix so that
          versioning is embedded in the library, rather than implied by
          links (patch by Tim Mooney).

980418
        + modify etip.h to avoid conflict with math.h on HP-UX 9.03 with gcc
          2.8.1 which redefines 'exception' (reported by Ralf Hildebrandt
          <R.Hildebrandt@tu-bs.de>).
        + correct configure tests in CF_SHARED_OPTS which used $CC value to
          check for gcc, rather than autoconf's $GCC value.  This did not
          work properly if the full pathname of the compiler were given
          (reported by Michael Yount <yount@csf.Colorado.edu>).
        + revise check for compiler options to force ANSI mode since repeating
          an option such as -Aa causes HP's compiler to fail on its own headers
          (reported by Clint Olsen <olsenc@ichips.intel.com>).

980411
        + ifdef'd has_key() and mcprint() as extended functions.
        + modified several prototypes to correspond with 1997 version of
          X/Open Curses (affects ABI since developers have used attr_get).
        + remove spurious trailing blanks in glibc addon-scripts (patch by
          H.J.Lu).
        + insert a few braces at locations where gcc-2.8.x asks to use them to
          avoid ambigous else's, use -fpic rather than -fPIC for Linux (patch
          by Juergen Pfeifer).

980404
        + split SHLIB_LIST into SHLIB_DIRS/SHLIB_LIST to keep -L options
          before -l to accommodate Solaris' linker (reported by Larry Virden).

980328
        + modify lib_color.c to eliminate dependency on orig_colors and
          orig_pair, since SVr4 curses does not require these either, but
          uses them when they are available.
        + add detailed usage-message to infocmp.
        + correct a typo in att6386 entry (a "%?" which was "?").
        + add -f option to infocmp and tic, which formats the terminfo
          if/then/else/endif so that they are readable (with newlines and
          tabs).
        + fixes for glibc addon scripts (patch by H.J.Lu).

980321
        + revise configure macro CF_SPEED_TYPE so that termcap.h has speed_t
          declared (from Adam J. Richter <adam@yggdrasil.com>)
        + remove spurious curs_set() call from leaveok() (J.T.Conklin).
        + corrected handling leaveok() in doupdate() (patch by Alexander V.
          Lukyanov).
        + improved version of wredrawln (patch by Alexander V. Lukyanov).
        + correct c++/Makefile.in so install target do not have embedded ../lib
          to confuse it (patch by Thomas Graf <graf@essi.fr>).
        + add warning to preinstall rule which checks if the installer would
          overwrite a curses.h or termcap.h that is not derived from ncurses.
          (The recommended configuration for developers who need both is to
          use --disable-overwrite).
        + modify preinstall rule in top-level Makefile to avoid implicit
          use of 'sh', to accommodate Ultrix 4.4 (reported by Joao Palhoto
          Matos <jmatos@math.ist.utl.pt>, patch by Thomas Esser
          <te@informatik.uni-hannover.de>)
        + refine ifdef's for TRACE so that libncurses has fewer dependencies
          on libtinfo when TRACE is disabled.
        + modify configure script so that if the --with-termlib option is used
          to generate a separate terminfo library, we chain it to the ncurses
          library with a "-l" option (reported by Darryl Miles and Ian T.
          Zimmerman).

980314
        + correct limits and window in wredrawln function (reported/analysis by
          Alexander V. Lukyanov).
        + correct sed expression in configure script for --with-fallback
          option (patch by Jesse Thilo).
        + correct some places in configure script where $enableval was used
          rather than $withval (patch by Darryl Miles <dlm@g7led.demon.co.uk>).
        + modify some man-pages so no '.' or '..' falls between TH and SH
          macros, to accommodate man_db program (reported by Ian T. Zimmerman
          <itz@rahul.net>).
        + terminfo.src 10.2.1 from Eric's webpage.
        > several changes by Juergen Pfeifer:
        + add copyright notices (and rcs id's) on remaining man-pages.
        + corrected prototypes for slk_* functions, using chtype rather than
          attr_t.
        + implemented the wcolor_set() and slk_color() functions
        + the slk_attr_{set,off,on} functions need an additional void*
          parameter according to XSI.
        + fix the C++ and Ada95 binding as well as the man pages to
          reflect above enhancements.

980307
        + use 'stat()' rather than 'access()' in toe.c to check for the
          existence of $HOME/.terminfo, since it may be a file.
        + suppress configure CF_CXX_LIBRARY check if we are not using g++
          2.7.x, since this is not needed with g++ 2.8 or egcs (patch by
          Juergen Pfeifer).
        + turn on hashmap scrolling code by default, intend to remedy defects
          by 4.3 release.
        + minor corrections to terminfo.src changelog.

980302  4.2 release for upload to prep.ai.mit.edu
        + correct Florian's email address in ncurses-intro.html
        + terminfo.src 10.2.0 from Eric.

980228  pre-release
        + add linux-koi8r replace linux-koi8, which is not KOI8 (patch by
          QingLong <qinglong@Bolizm.ihep.su>).
        + minor documentation fixes (patch by Juergen Pfeifer).
        + add setlocale() call to ncurses.c (reported by Claes G. Lindblad
          <claesg@algonet.se>).
        + correct sign-extension in lib_insstr.c (reported by Sotiris
          Vassilopoulos <svas@leon.nrcps.ariadne-t.gr>)

980221  pre-release
        + regenerated some documentation overlooked in 980214 patch
          (ncurses-intro.doc, curs_outopts.3x.html)
        + minor ifdef change to C++ binding to work with gcc 2.8.0 (patch by
          Juergen Pfeifer).
        + change maintainer's mailing address to florian@gnu.org, change
          tentative mailing list address to bug-ncurses-request@gnu.org (patch
          by Florian La Roche).
        + add definition of $(REL_VERSION) to c++/Makefile.in (reported by Gran
          Hasse <gh@raditex.se>).
        + restore version numbers to Ada95 binding, accidentally deleted by
          copyright patch (patch by Juergen Pfeifer).

980214  pre-release
        + remove ncurses.lsm from MANIFEST so that it won't be used in FSF
          distributions, though it is retained in development.
        + correct scaling of milliseconds to nanoseconds in lib_napms.c (patch
          by Jeremy Buhler).
        + update mailing-list information (bug-ncurses@gnu.org).
        + update announcement for upcoming 4.2 release.
        + modify -lm test to check for 'sin()' rather than 'floor()'
        + remove spurious commas from terminfo.src descriptions.
        + change copyright notices to Free Software Foundation

980207
        + minor fixes for autoconf macros CF_ERRNO, CF_HELP_MESSAGE and
          CF_SIZECHANGE
        + modify Makefile.glibc so that $(objpfx) is defined (H.J.Lu).
        + ifdef-out true-return from _nc_mouse_inline() which depends on
          merge of QNX patch (pending 4.2 release).
        > patch by J.T.Conklin, to split off seldom-used modules in ncurses
          (reduces size by up to 2.6kb):
        + move functionality of _nc_usleep into napms, add configuration case
          for nanosleep().
        + moved wchgat() from lib_addch.c to lib_chgat.c
        + moved clearok(), immedok(), leaveok(), and scrollok() from
          lib_options.c to lib_clearok.c, lib_immedok.c, lib_leaveok.c and
          lib_scrollok.c.
        + moved napms() from lib_kernel.c to lib_napms.c
        + moved echo() and noecho() from lib_raw.c to lib_echo.c
        + moved nl() and nonl() from lib_raw.c to lib_nl.c

980131
        + corrected conversion in tclock.c (cf: 971018).
        + updates to Makefile.glibc and associated Linux configure script
          (patch by H.J.Lu).
        + workaround a quoting problem on SunOS with tar-copy.sh
        + correct init_pair() calls in worm.c to work when use_default_colors()
          is not available.
        + include <sys/types.h> in CF_SYS_TIME_SELECT to work with FreeBSD
          2.1.5
        + add ncv capability to FreeBSD console (cons25w), making reverse
          work with color.
        + correct sense of configure-test for sys/time.h inclusion with
          sys/select.h
        + fixes for Ada95/ada_include/Makefile.in to work with --srcdir option.
        + remove unused/obsolete test-program rules from progs/Makefile.in
          (the rules in ncurses/Makefile.in work).
        + remove shared-library loader flags from test/Makefile.in, etc.
        + simplify test/configure.in using new version of autoconf to create
          test/ncurses_cfg.h
        + suppress suffix rules in test/Makefile.in, provide explicit
          dependency to work with --srcdir option and less capable 'make'
          programs.
        > adapted from patch for QNX by Xiaodan Tang:
        + initialize %P and %g variables set/used in tparm, and also ensure
          that empty strings don't return a null result from tparam_internal
        + add QNX-specific prototype for vsscanf()
        + move initialization of SP->_keytry from init_keytry() to newterm() to
          avoid resetting it via a keyok() call by mouse_activate().
        + reorganized some functions in lib_mouse() to use case-statements.
        + remove sgr string from qnx terminfo entry since it is reported to
          turn off attributes inconsistently.

980124
        + add f/F/b/B commands to ncurses 'b' test to toggle colors, providing
          test for no_color_video.
        + adjusted emx.src to use no_color_video, now works with ncurses 'b'
          and 'k' tests.
        + implement no_color_video attribute, and as a special case, reverse
          colors when the reverse attribute cannot be combined with color.
        + check for empty string in $TERM variable (reported by Brett Michaels
          <brett@xylan.com>).
        > from reports by Fred Fish:
        + add configure-test for isascii
        + add configure-test for -lm library.
        + modify CF_BOOL_SIZE to check if C++ bool types are unsigned.
        > patches by J.J.G.Ripoll
        + add configure/makefile variables to support .exe extension on
          OS/2 EMX (requires additional autoconf patches).
        + explicitly initialize variables in lib_data.c to appease OS/2 linker
        > patches by Fred Fish <fnf@ninemoons.com>
        + misc/Makefile.in (install.data):  Avoid trying to install the CVS
          directory.
        + aclocal.m4 (install.includes):  Remove files in the include directory
          where we are going to install new ones, not the original source
          files.
        + misc/terminfo.src:  Add entry for "beterm", derived from termcap
          distributed with BeOS PR2 using captoinfo.
        + aclocal.m4: Wrap $cf_cv_type_of_bool with quotes (contains space)
        + aclocal.m4: Assume bool types are unsigned.
        + progs/infocmp.c: workaround mwcc 32k function data limit

980117
        + correct initialization of color-pair (from 970524) in xmas.c, which
          was using only one color-pair for all colors (reported by
          J.J.G.Ripoll).
        + add multithread options for objects build on EMX, for compatibility
          with XFree86.
        + split up an expression in MKlib_gen.sh to work around a problem on
          OS/2 EMX, with 'ash' (patch by J.J.G.Ripoll).
        + change terminfo entries xterm (xterm-xf86-v40), xterm-8bit rs1 to use
          hard reset.
        + rename terminfo entry xterm-xf86-v39t to xterm-xf86-v40
        + remove bold/underline from sun console entries since they're not
          implemented.
        + correct _tracef calls in _tracedump(), which did not separate format
          from parameters.
        + correct getopt string for tic "-o" option, and add it to man-page
          synopsis (reported by Darren Hiebert <darren@hmi.com>).
        + correct typo in panel/Makefile.in, reversed if-statement in scrolling
          optimization (Alexander V.  Lukyanov).
        + test for 'remove()', use 'unlink() if not found (patch by Philippe De
          Muyter <phdm@macqel.be>).
        > patches by Juergen Pfeifer:
        + Improve a feature of the forms driver.  For invisible fields
          (O_VISIBLE off) only the contents but not the attributes are cleared.
          We now clear both.  (Reported by Javier Kohan
          <jkohan@adan.fceia.unr.edu.ar>)
        + The man page form_field_opts.3x makes now clear, that invisible
          fields are also always inactive.
        + adjust ifdef's to compile the C++ binding with the just released
          gcc-2.8.0 c++ and the corresponding new C++ libraries.

980110
        + correct "?" command in ncurses.c; it was performing non-screen writes
          while the program was in screen mode.  (It "worked" in 1.9.9e because
          that version sets OPOST and OCRNL incorrectly).
        + return error from functions in lib_kernel, lib_raw and lib_ti if
          cur_term is null, or if underlying I/O fails.
        + amend change to tputs() so that it does not return an error if
          cur_term is null, since some applications depend on being able to use
          tputs without initializing the terminal (reported by Christian J.
          Robinson <infynity@cyberhighway.net>).

980103
        + add a copy of emx.src from J.J.G.Ripoll's OS/2 EMX version of ncurses
          1.9.9e, together with fixes/additions for the "ansi" terminal type.
        + add tic check for save/restore cursor if change_scroll_region is
          defined (from O'Reilly book).
        + modify read_termcap.c to handle EMX-style pathnames (reported by
          J.J.G.Ripoll).
        + modify lib_raw.c to use EMX's setmode (from J.J.G.Ripoll, who says
          EMX's curses does this).
        + modify _nc_tic_expand() to generate \0 rather than \200.
        + move/revise 'expand()' from dump_entry.c to ncurses library as
          _nc_tic_expand(), for use by tack.
        + decode \a as \007 for terminfo, as per XSI.
        + correct translation of terminfo "^@", to \200, like \0.
        + modify next_char() to treat <cr><lf> the same as <newline>, for
          cross-platform compatibility.
        + use new version of autoconf (971230) to work around limited
          environment on CLIX, due to the way autoconf builds --help message.
        > patch by Juergen Pfeifer:
        + check that the Ada95 binding runs against the correct version of
          ncurses.
        + insert constants about the library version into the main spec-file of
          the Ada95 binding.

        + modify open/fopen calls to use binary mode, needed for EMX.
        + modify configure script to work with autoconf 2.10 mods for OS/2
          EMX from J.J.G.Ripoll.
        + generated ncurses_cfg.h with patch (971222) to autoconf 2.12 which
          bypasses limited sed buffer length.
        > several changes from Juan Jose Garcia Ripoll <worm@arrakis.es>
          (J.J.G.Ripoll) to support OS/2 EMX:
        + add a _scrolling flag to SP, to set when we encounter a terminal
          that simply cannot scroll.
        + corrected logic in _nc_add_to_try(), by ensuring that strings with
          embedded \200 characters are matched.
        + don't assume the host has 'link()' function, for linking terminfo
          entries.

971220
        + if there's no ioctl's to support sigwinch handler, disable it.
        + add configure option --disable-ext-funcs to remove the extended
          functions from the build.
        + add configure option --with-termlib to generate the terminfo
          functions as a separate library.
        + add 'sources' rule to facilitate cross-compiling.
        + review/fix order of mostlyclean/clean/distclean rules.
        + modify install-rule for headers to first remove old header, in
          case there was a symbolic link that confuses the install script.
        + corrected substitution for NCURSES_CONST in term.h (cf: 971108)
        + add null pointer checks in wnoutrefresh(), overlap() (patch by
          Xiaodan Tang <xtang@qnx.com>)
        + correct tputs(), which could dereference a null cur_term if invoked
          before terminal is initialized (patch by Christopher Seawood
          <cls@seawood.org>)
        > patch by Juergen Pfeifer:
        + makes better use of "pragma Inline" in the Ada95 binding
        + resynchronizes the generated html manpages

971213
        + additional fixes for man-pages section-references
        + add (for debugging) a check for ich/ich1 conflict with smir/rmir
          to tic, etc.
        + remove hpa/vpa from rxvt terminal description because they are not
          implemented correctly, added sgr0.
        + change ncurses 's' to use raw mode, so ^Q works (reported by Rudolf
          Leitgeb <leitgeb@leland.stanford.edu>)

971206
        + modify protection when installing libraries to (normally) not
          executable.  HP-UX shared libraries are an exception.
        + add configure check for 'tack'.
        + implement script for renaming section-references in man-page install,
          for Debian configuration.
        + add validity-check for SP in trace code in baudrate() (reported by
          Daniel Weaver).
        > patch by Alexander V. Lukyanov (fixes to match sol25 curses)
        + modify 'overlay()' so that copy applies target window background to
          characters.
        + correct 'mvwin()' so that it does not clear the previous locations.
        + correct lib_acs.c so that 8-bit character is not sign expanded in
          case of wide characters in chtype.
        + correct control-char test in lib_addch.c for use with wide chars
        + use attribute in the chtype when adding a control character in
          lib_addch.c control char was added with current attribute

971129
        + save/restore errno in _tracef() function
        + change treatment of initialize_color to use a range of 0..1000
          (recommended by Daniel Weaver).
        + set umask in mkinstalldirs, fixing problems reported by users who
          have set root's umask to 077.
        + correct bug in tic that caused capabilities to be reprinted at the
          end of output when they had embedded comments.
        + rewrote wredrawln to correspond to XSI, and split-out since it is
          not often used (from report by Alexander V. Lukyanov, 970825)
        + rewrote Dan Nelson's change to make it portable, as well as to
          correct logic for handling backslashes.
        + add code to _nc_tgetent() to make it work more like a real tgetent().
          It removes all empty fields, and removes all but the first in a group
          of duplicate caps.  The code was pulled from the BSD libtermcap code
          in termcap.c (patch by Dan Nelson <dnelson@emsphone.com>
        + don't include --enable-widec in the --with-develop configure option,
          since it is not binary-compatible with 4.1 (noted by Alexander V.
          Lukyanov)
        > patch by Juergen Pfeifer:
        + further improvements of the usage of elaboration pragmas in the Ada95
          binding
        + enhanced Ada95 sample to use the user_data mechanism for panels.
        + a fix for the configuration script to make gnat-3.10 the required
          version.
        + resync of the html version of the manpages

971122
        > fixes/updates for terminfo.src:
        + add vt220-js, pilot, rbcomm, datapoint entries from esr's 27-jun-97
          version.
        + add hds200 description (Walter Skorski)
        + add EMX 0.9b descriptions
        + correct rmso/smso capabilities in wy30-mc and wy50-mc (Daniel Weaver)
        + rename xhpterm back to hpterm.
        > patch by Juergen Pfeifer:
        + Improves the usage of elaboration pragmas for the Ada95 binding.
        + Adds a translation of the test/rain.c into Ada95 to the samples.
          This has been contributed to the project by Laurent Pautet
          (pautet@gnat.com)

971115
        + increase MAX_NAME_SIZE to 512 to handle extremely long alias list
          in HP-UX terminfo.
        + correction & simplification of delay computation in tputs, based on
          comments from Daniel Weaver.
        + replace test for SCO with more precise header tests.
        + add configure test for unsigned literals, use in NCURSES_BITS macro.
        + comment-out the -PIC, etc., flags from c++, progs and test makefiles
          since they probably are not needed, and are less efficient (noted by.
          Ju"rgen Fluk)
        + add -L$(libdir) to loader options, after -L../lib so that loaders
          that record this information will tend to do the right thing if
          the programs are moved around after installing them (suggested by.
          Ju"rgen Fluk).
        + add -R option to loader options for programs for Solaris if the
          --enable-rpath option is specified for the libraries.

971112
        + correct installed filename for shared libraries on *BSD (reported by
          Ju"rgen Fluk).

971108
        + cleanup logic for deciding when tputs() should call delay_output(),
          based on comments from Daniel Weaver.
        + modified tputs() to avoid use of float.
        + correct use of trailpad in tputs(), which used the wrong variable
          in call to delay_output().
        + correct inverted expression for null-count in delay_output()
          (analysis by Daniel Weaver).
        + apply --enable-rpath option to Solaris (requested by Larry Virden).
        + correct substitution of EXTRA_CFLAGS for gcc 2.6.3
        + correct check for error-return by _nc_tgetent(), which returns 0
          for success.
        + add configure test for BSD 4.4 cgetent() function, modify
          read_termcap.c to use the host's version of that if found, using the
          terminal database on FreeBSD (reported by Peter Wemm).
        + add u8, u9 strings to sun-il description for Daniel Weaver.
        + use NCURSES_CONST in panel's user-pointer.
        + modify edit_cfg.sh and MKterm.h.awk.in to substitute NCURSES_CONST
          so that will work on NeXT.
        + use _nc_set_screen() rather than assignments to SP to fix port to
          NeXT (reported by Francisco A. Tomei Torres).

971101
        + force mandatory padding in bell and flash_screen, as specified in
          XSI.
        + don't allow padding_baud_rate to override mandatory delays (reported
          by Daniel Weaver).
        + modify delay_output() to use _nc_timed_wait() if no baudrate has been
          defined, or if the cur_term pointer is not initialized.  XSI treats
          this as unspecified.  (requested by Daniel Weaver).
        + change getcap-cache ifdef's to eliminate unnecessary chdir/mkdir
          when that feature is not configured.
        + remove _nc_err_abort() calls when write_entry.c finds a directory but
          cannot write to it, e.g., when translating part/all of /etc/termcap
          (reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>).
          (this dates back to 951102, in 1.9.7a).
        + minor ifdef fixes to compile with atac and glibc 2.0.5c
        + add check for -lgen when configuring regexpr.h
        + modify Solaris shared-library option "-d y" to "-dy" to workaround
          incompatibility of gcc 2.7.2 vs vendor's tools.

971026
        + correct ifdef's for struct winsize vs struct ttysize in lib_setup.c
          to compile on SCO.
        + remove dangling backslash in panel/Makefile.in
        + modify MKkeyname.awk to work with SCO's nawk, which dumps core in the
          length() function.
        + correct length of allocation in _nc_add_to_try(), to allow for
          trailing null.
        + correct logic in _nc_remove_key(), which was discarding too many
          nodes (patch by Alexander V. Lukyanov)

971025
        + add definition for $(REL_VERSION) to test/Makefile.in, so *BSD
          shared libraries link properly (see 970524).
        + modify Linux shared-library generation to include library
          dependencies (e.g., -lncurses and -lgpm) in the forms, menu and
          panel libraries (suggested by Juergen Pfeifer).
        + modify configure script to use config.guess and config.sub rather
          than uname, which is unreliable on some systems.
        + updated Makefile.glibc, test-built with glibc 2.0.5c
        + modify keyname() to return values consistent with SVr4 curses (patch
          by Ju"rgen Fluk).
        > changes requested by Daniel Weaver:
        + modify delay_output() so that it uses the same output function as
          tputs() if called from that function.
        + move _baudrate from SCREEN to TERMINAL so that low-level use of
          tputs works when SP is not set.
        > patch by Juergen Pfeifer:
        + factor lib_menu and lib_form into smaller modules
        + clean up the interface between panel and SCREEN
        + minor changes to the Ada95 mouse support implemenation
        + minor bugfix in C++ binding to ripoff windows
        + fix a few Ada95 html documentation pages

971018
        + split-out lib_ungetch.c, make runtime link to resizeterm() to
          decouple those modules from lib_restart.c
        + add xterm-xf86-v39t description to terminfo.src
        + reset SP->_endwin in lib_tstp.c cleanup() function after calling
          endwin() to avoid unnecessary repainting if the application has
          established an atexit function, etc.  Encountered this problem in
          the c++ demo, whose destructors repaint the screen.
        + combine _nc_get_screensize() and resizeterm() calls as new function
          _nc_update_screensize().
        + minor fixes to allow compile with g++ (suggested by Nelson H. F.
          Beebe).
        + implement install-rules for Ada95 makefiles.
        + use screen_lines or MAXLINES as needed where LINES was coded,
          as well as screen_columns for COLS, in the ncurses library.
        > patch by Alexander V. Lukyanov:
        + modify logic for ripped-off lines to handle several SCREENs.
        > patch by Juergen Pfeifer:
        + factors lib_slk.c into some smaller modules
        + factors panel.c into some smaller modules
        + puts the static information about the current panel stack into the
          SCREEN structure to allow different panel stacks on different
          screens.
        + preliminary fix for an error adjusting LINES to account for
          ripped-off lines.

971011
        + move _nc_max_click_interval and other mouse interface items to SCREEN
          struct so that they are associated with a single terminal, and also
          save memory when the application does not need a mouse (roughly 3k vs
          0.5k on Linux).
        + modify mouseinterval() so that a negative parameter queries the
          click-interval without modifying it.
        + modify ncurses 'i' test to work with ncurses' apparent extension from
          SVr4, i.e., allows nocbreak+noecho (analysis by Alexander V.
          Lukyanov).
        + add configure options --with-ada-includes and --with-ada-objects,
          to drive Ada95 binding install (not yet implemented).
        + install C++ binding as -lncurses++ and associated headers with the
          other ncurses headers.
        + fix header uninstall if configure --srcdir is used.
        > minor interface changes (request by Daniel Weaver <danw@znyx.com>,
          to support 'tack' program):
        + export functions _nc_trans_string() and _nc_msec_cost().
        + add variable _nc_nulls_sent, to record the number of padding
          characters output in delay_output().
        + move tests for generic_type and hard_copy terminals in setupterm()
          to the end of that function so that the library will still be
          initialized, though not generally useful for curses programs.
        > patches by Alexander V. Lukyanov:
        + modify ClrBottom() to avoid using clr_eos if there is only one line
          to erase.
        + typo in configure --help.
        > patch by J.T.Conklin (with minor resync against Juergen's changes)
        + split-out lib_flash.c from lib_beep.c
        + split-out lib_hline.c and lib_vline.c from lib_box.c
        + split-out lib_wattron.c, lib_wattroff.c from lib_addch.c

971005
        > patch by Juergen Pfeifer:
        + correct source/target of c++/edit_cfg.sh

971004
        + add color, mouse support to kterm terminfo entry.
        + modify lib_mouse.c to recognize rxvt, kterm, color_xterm also as
          providing "xterm"-style mouse.
        + updated rxvt's terminfo description to correspond to 2.21b, with
          fixes for the acsc (the box1 capability is incorrect, ech1 does not
          work).
        + fix logic in parse_entry.c that discarded acsc when 'synthesizing'
          an entry from equivalents in XENIX or AIX.  This lets ncurses handle
          the distribution copy of rxvt's terminfo.
        + modify acsc capability for linux and linux-koi8 terminfo descriptions
          (from Pavel Roskin <pavel@absolute.spb.su>).
        + corrected definition in curses.h for ACS_LANTERN, which was 'I'
          rather than 'i' (see 970802).
        + updated terminfo.src with reformatted acsc entries, and repaired the
          trashed entries with spurious '\' characters that this exposed.
        + add logic to dump_entry.c to reformat acsc entries into canonical
          form (sorted, unique mapping).
        + add configure script to generate c++/etip.h
        + add configure --with-develop option, to enable by default most of the
          experimental options (requested by Alexander V. Lukyanov).
        + rename 'deinstall' to 'uninstall', following GNU convention
          (suggested by Alexander V. Lukyanov).
        > patches by Alexander V. Lukyanov:
        + modify tactics 2 and 5 in onscreen_mvcur(), to allow them on the last
          line of the screen, since carriage return will not cause a newline.
        + remove clause from PutCharLR() that would try to use
          eat_newline_glitch since that apparently does not work on some
          terminals (e.g., M$ telnet).
        + correct a limit check in scroll_csr_backward()
        > patches by Juergen Pfeifer:
        + adds dummy implementations of methods above() and below() to the
          NCursesPanel class.
        + fixes missing returncode in NCursesWindow::ripoffline()
        + fixes missing returncode in TestApplication::run() in demo.cc
        + We should at least give a comment in etip.h why it is currently a
          problem to install the C++ binding somewhere
        + makes the WINDOW* argument of wenclose() a const.
        + modifies several of the routines in lib_adabind.c to use a const
          WINDOW* argument.

970927
        + add 'deinstall' rules.
        + use explicit assignments in configure --without-progs option to
          work around autoconf bug which doesn't always set $withval.
        + check for ldconfig, don't try to run it if not found.
        + implement simple/unoptimized case in lib_doupdate.c to handle
          display with magic cookie glitch, tested with ncurses.c program.
        + correct missing _tracef in getmouse(), to balance the returnCode
          macro.
        + simplify show_attr() in ncurses.c using termattrs().
        > patches by Juergen Pfeifer:
        + provides missing inlines for mvw[hv]line in cursesw.h of the C++
          binding
        + fixes a typo in a comment of frm_driver.c
        + Enhances Ada95 Makefiles to fulfill the requirement of GNAT-3.10 that
          generics should be compiled.  Proper fixes to the configuration
          scripts are also provided.

970920
        + several modifications to the configure script (requested by Ward
          Horner):
          + add configure options --without-progs, to suppress the build of the
            utility programs, e.g., for cross-compiling.
          + add $(HOSTCCFLAGS) and $(HOSTLDFLAGS) symbols to ncurses
            Makefile.in, to simplify setup for cross compiling.
          + add logic in configure script to recognize "--target=vxworks", and
            generate load/install actions for VxWorks objects.
        + move typedef for sigaction_t into SigAction.h to work around problem
          generating lint library.
        + modify fty_regex.c to reflect renaming of ifdef's for regular
          expressions.
        + simplify ifdef in lib_setup.c for TIOCGWINSZ since that symbol may
          reside in <sys/ioctl.h>.
        + merge testcurs.c with version from PDCurses 2.3, clarifying some of
          the more obscure tests, which rely upon color.
        + use macros getbegyx() and getmaxyx() in newdemo.c and testcurs.c
        + modify ncurses.c to use getbegyx() and getmaxyx() macros to cover up
          implementation difference wrt SVr4 curses, allow 's' test to work.
        + add missing endwin() to testscanw.c program (reported by Fausto
          Saporito <fausap@itb.it>).
        + fixes/updates for Makefile.glibc and related files under sysdeps
          (patch by H.J.Lu).
        > patches by Juergen Pfeifer:
        + add checks for null pointers, especially WINDOW's throughout the
          ncurses library.
        + solve a problem with wrong calculation of panel overlapping (reported
          by Ward Horner):
          + make sure that a panel's window isn't a pad.
          + do more error checking in module lib_touch.c
        + missing files for Ada95 binding from the last patch
        + synch. of generated html pages (RCS-Id's were wrong in html files)
        + support for Key_Resize in Ada binding
        + changed documentation style in ./c++/cursesm.h
        > patches by Alexander V. Lukyanov:
        + undo attempt to do recursive inlining for PutChar(), noting that it
          did not improve timing measurably, but inflated the size of
          lib_doupdate.o

970913
        + modify rain.c to use color.
        + correct scroll_csr_backward() to match scroll_csr_forward().
        + minor adjustment to llib-lncurses, to work with Solaris 2.5.1
        + minor fixes to sysdeps/unix/sysv/linux/configure to reflect renaming
          of configure cache variables in 970906.
        + correct logic involving changes to O_VISIBLE option in
          Synchronize_Options function in frm_driver.c (Tony Hoffmann
          <Tony.Hoffmann@hia.nrc.ca>)
        + add $(HOSTCC) symbol to ncurses Makefile.in, to simplify setup for
          cross compiling (suggested by Chris Johns).
        + modify ifdef in lib_setup.c to only include <sys/ioctl.h> if we can
          use it to support screen-size calculation (reported by Chris Johns).
        + #undef unctrl to avoid symbol conflict in port to RTEMS (reported by
          Chris Johns <cjohns@plessey.com.au>)
        > patches by Juergen Pfeifer:
        + simplified, made minor corrections to Ada95 binding to form
          fieldtype.
        + The C++ binding has been enhanced:
          + Improve NCursesWindow class:  added additional methods to cover
            more ncurses functionality.  Make refresh() and noutrefresh()
            virtual members to allow different implementation in the
            NCursesPanel class.
