ncurses-5.4

	  pathname of libtool (report by Chris Zubrzycki).  We note that
	  libtool 1.5 has more than one bug in its C++ support, so it is not
	  able to install libncurses++, for instance, if $DESTDIR or the option
	  --with-install-prefix is used.

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

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

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

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

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

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

20030712
	+ update config.guess, config.sub
	+ add triples for configuring shared libraries with the Debian
	  GNU/FreeBSD packages (patch by Robert Millan <[e-mail]>).

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

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

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

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

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

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

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

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

20030510
	+ make typography for program options in manpages consistent (report
	  by Miloslav Trmac <[e-mail]>).
	+ correct dependencies in Ada95/src/Makefile.in, so the builds with
	  "--srcdir" work (report by Warren L Dodge).
	+ correct missing definition of $(CC) in Ada95/gen/Makefile.in
	  (reported by Warren L Dodge <[e-mail]>).
	+ fix typos and whitespace in manpages (patch by jmc
	  <[e-mail]>).

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

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

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

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

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

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

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

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

20030301
	+ restructured test/configure script, make it work for libncursesw.
	+ add description of link_fieldtype() to manpage (report by
	  L Dee Holtsclaw <[e-mail]>).

20030222
	+ corrected ifdef's relating to configure check for wchar_t, etc.
	+ if the output is a socket or other non-tty device, use 1 millisecond
	  for the cost in mvcur; previously it was 9 milliseconds because the
	  baudrate was not known.
	+ in _nc_get_tty_mode(), initialize the TTY buffer on error, since
	  glibc copies uninitialized data in that case, as noted by valgrind.
	+ modify tput to use the same parameter analysis as tparm() does, to
	  provide for user-defined strings, e.g., for xterm title, a
