> New features
> 
>- There are a few new features:
>- * A new (experimental) driver, for the Windows Terminal
>- configuration is provided.
>- * A script is provided which enables OpenBSD users to upgrade their
>- system to use ncurses 6.3 (OpenBSD developers are also invited to
>- do this).
>-
>- Additionally, to improve performance other changes (and extensions)
>- are provided in this release:
>- * modify lib_mouse.c to check for out-of-range button numbers,
>- convert those to position reports.
>- * add sp-funcs for erasewchar, killwchar.
>+ There are no new features in this release.
> 
> Other improvements
> 
>- These are revised features:
>- * modify wgetnstr, wgetn_wstr to improve compatibility with SVr4
>- curses in its treatment of interrupt and quit characters
>-
>- These were done to limit or ultimately deprecate features:
>- * mark wgetch-events feature as deprecated.
>- + prevent KEY_EVENT from appearing in curses.h unless the
>- configure option --enable-wgetch-events is used.
>- + modify MKkey_defs.sh to hide ncurses' definition of
>- KEY_EVENTS to reduce Visual Studio C++ redefinition warnings.
>- * reduce build-warnings by excluding ncurses-internals from
>- deprecation warnings.
>-
> These are improvements to existing features:
>- * drop symbols GCC_PRINTF and GCC_SCANF from <curses.h>, to simplify
>- use.
>- * apply gcc format attribute to prototypes which use a va_list
>- parameter rather than a "..." variable-length parameter list.
>- * modify <term.h> so that it is not necessary to include <curses.h>
>- before <term.h>.
>- * provide for wide-characters as background character in wbkgrnd
>- * improve parameter-checking for tparm, adding function _nc_tiparm()
>- to handle the most-used case, which accepts only numeric
>- parameters.
>- * use return-value from vsnprintf to reallocate as needed to allow
>- for buffers larger than the screen size.
>- * add another fflush(stdout) in _nc_flush to handle time-delays in
>- the middle of strings such as flash when the application uses
>- low-level calls rather than curses.
>+ * modify delscreen to more effectively delete all windows on the
>+ given screen.
>+ * modify wnoutrefresh to call pnoutrefresh if its parameter is a
>+ pad, rather than treating it as an error, and modify new_panel to
>+ permit its window-parameter to be a pad
>+ * modify curses_trace() to show the trace-mask as symbols, e.g.,
>+ TRACE_ORDINARY, DEBUG_LEVEL(3).
>+ * improve checks for valid mouse events when an intermediate mouse
>+ state is not part of the mousemask specified by the caller
>+ * allow extended-color number in opts parameter of wattr_on.
>+ * improve _tracecchar_t2 formatting of base+combining character.
>+ * trim out some unwanted linker options from ncurses*config and .pc
>+ files seen in Fedora 36+.
>+ * improve shell-scripts with shellcheck
>+ * improve use of "trap" in shell scripts, using a script.
>+ * modify make-tar.sh scripts to make timestamps more predictable.
> 
> These are corrections to existing features:
>- * add a check to guard against repeat_char emitting digits which
>- could be interpreted as BSD-style padding when --enable-bsdpad is
>- configured.
>- * check for screen size-change in scr_init and scr_restore, in case
>- a screen dump does not match the current screen dimensions
>+ * modify misc/gen-pkgconfig.in to allow for the case where the
>+ library directory does not yet exist, since this is processed
>+ before doing an install
>+ * set trailing null on string passed from winsnstr to wins_nwstr.
>+ * modify waddch_literal to allow for double-width base character
>+ when merging a combining character
> 
> Program improvements
> 
> Several improvements were made to the utility programs:
> 
>- tabs
>+ infocmp
> 
>- + implement "+m" option
>+ + rewrite canonical_name function of infocmp to ensure buffer
>+ size
>+ + improve readability of long parameterized expressions with
>+ the infocmp "-f" option by allowing split before a "%p"
>+ marker.
>+ + modify verbose-option of infocmp, tic, toe to enable
>+ debug-tracing if that is configured.
> 
>- tic
>+ tabs
>+ limit tab-stop values to max-columns

>- compatible XT flag.
>- + improve checks for number of parameters of smglp, smgrp,
>- smgtp, and smgbp.
>- + improve "-c" option to validate the number and type of
>- parameters and compare against expected number/type before
>- deciding which set of parameter-lists to use in tparm calls.
>- + improve check for errors detected in tparm.
>- + improve format of output, to ensure that the messages contain

> Examples
> 
> Along with the library and utilities, improvements were made to the
> ncurses-examples. Most of this activity aimed at improving the
>- test-packages. A few changes are more generally useful, e.g., for the
>- main ncurses test-program, and for analyzing traces using the
>- tracemunch script:
>- * add "-r" option to the dots test-programs, to help with scripting
>- a performance comparison.
>- * build-fix for test_opaque, for configurations without opaque
>- curses structs, e.g., ncurses 5.7.
>- * improve tracemunch logic for "RUN" compaction.
>- * improve tracemunch's coverage of form/menu/panel libraries.
>- * improve tracemunch's checking/reporting the type for the first
>- parameter, e.g., "WINDOW*" rather than "#1".
>- * modify tracemunch and the panel library to show readable traces
>- for panel- and user-pointers.
>+ test-packages:
>+ * add minimal -h (usage) and -V (version) getopt logic to all
>+ ncurses-examples programs.
>+ * fix an error in "@" command in test/ncurses.c F-menu
>+ * add curses_trace to ifdef's for START_TRACE in test/test.priv.h
>+ * improve pthread-configuration for test/worm.c
>+ * add setlocale call to several test-programs.
>+ * workaround in test/picsmap.c for use of floating point for rgb
>+ values by ImageMagick 6.9.11, which appears to use the wrong upper
>+ limit.
>+ * use static libraries for AdaCurses test-package for Mageia, since
>+ no gprbuild package is available.
>+ * install Ada95 sample programs in libexecdir, adding a wrapper
>+ script to invoke those.
>+ * install ncurses-examples programs in libexecdir, adding a wrapper
>+ script to invoke those.

>+ While there were many bugs fixed during development of ncurses 6.4,
> only a few (the reason for this release) were both important and
> interesting. Most of the bug-fixes were for local issues which did not
> affect compatibility across releases. Since those are detailed in the
> NEWS file no elaboration is needed here.
> 
>- The interesting bugs were:
>- * modify wbkgd and wbkgrnd to avoid storing a null in the background
>- character, because it may be used in cases where the corresponding
>- 0x80 is not treated as a null.
>- This was a regression introduced in ncurses 6.2 (reported on the
>- mailing list), for which the workaround was to specify a blank for
>- the background character.
>- * remove output-related checks for nl/nonl (also reported on the
>- mailing list).
>- * improve tparm implementation of %P and %g, more closely matching
>- SVr4 terminfo. Those denote static and dynamic variables in
>- terminfo expressions.
>- Exactly what those terms meant was never documented before in any
>- implementation of curses, aside from source code. Unlike the other
>- two fixes, the problem was discovered while studying OpenBSD's
>- version of tset.
>+ The interesting bugs were those dealing with memory leaks and buffer
>+ overflows. Although the utilities are designed for text files (which
>+ they do properly), some choose to test them with non-text files.
>+ * Text files contain no embedded nulls. Also, they end with a
>+ newline. Feeding tic non-text files exposed a few cases where the
>+ program did not check for those issues. As a result, further
>+ processing of the input found limit-checks whose assumptions were
>+ invalid.
>+ * Fixing the limit-checks (first) found a problem with tic managing
>+ the list of strings in a terminal description. In merging two
>+ terminal descriptions (i.e., the "use=" feature), tic was not
>+ allocating a complete copy. A quick repair for that introduced a
>+ memory leak.
>+ * The checks for non-text files are improved (i.e., embedded nulls
>+ in the input file will cause tic to reject it rather than
>+ attempting to process it).
>+ * The string allocations in tic are likewise improved.
> 
> Configuration changes

>- integration of packages with systems using different versions of GNAT
>- and ncurses. Also, improvements were made to configure checks.

> Portability
> 
> Many of the portability changes are implemented via the configure
> script:
>- * add a special case in the configure script to work around one of
>- the build-time breakages reported for OpenBSD 6 here:
>-
>- https://www.mail-archive.com/bugs@openbsd.org/msg13200.html
>- * modify configure check for libtool to prevent accidental use of an
>- OpenBSD program which uses the same name.
>- * modify configuration checks for build-time tic/infocmp to use
>- AC_CHECK_TOOL. That can still be overridden by --with-tic-path and
>- --with-infocmp-path when fallbacks are used, but even if not using
>- fallbacks, the improved check may help with cross-compiling.
>- * relax modification-time comparison in CF_LINK_FUNCS to allow it to
>- accept link() function with NFS filesystems which change the mtime
>- on the link target, e.g., several BSD systems.
>- * modify configure check for c89/c99 aliases of clang to use its
>- -std option instead, because some platforms, in particular macOS,
>- do not provide workable c89/c99 aliases.
>- * modify CF_NCURSES_CONFIG to work around Xcode's c99 "-W" option,
>- which conflicts with conventional use for passing linker options.
>- * modify configure scripts to filter out redefinitions of
>- _XOPEN_SOURCE, e.g., for NetBSD which generally supports 500, but
>- 600 is needed for ncursesw.
>+ * amend configure option's auto-search to account for systems where
>+ none of the directories known to pkg-config exist
>+ * corrected regex needed for older pkg-config used in Solaris 10
>+ * improve handling of --with-pkg-config-libdir option, allowing for
>+ the case where either $PKG_CONFIG_LIBDIR or the option value has a
>+ colon-separated list of directories
>+ * if the --with-pkg-config-libdir option is not given, use
>+ ${libdir}/pkgconfig as a default
>+ * improve search-path check for pkg-config, e.g., for Debian testing
>+ which installs pkg-config with architecture-prefixes.
>+ * build-fix for cross-compiling to MingW, conditionally add -lssp
>+ * improve configure check for getttynam
>+ * fixes to build with dietlibc:
>+ + add configure check for fpathconf
>+ + add configure check for math sine/cosine, needed in
>+ test/tclock, and eliminate pow() from test/hanoi
>+ + use wcsnlen as an alternative to wmemchr if it is not found
>+ * modify configure macro CF_BUILD_CC to check if the build-compiler
>+ works, rather than that it is different from the cross-compiler,
>+ e.g., to accommodate a compiler which can be used for either
>+ purpose with different flags
>+ * modify configure/scripts to work around interference by GNU grep
>+ 3.8
> 
> Here are some of the other portability fixes:
>- * change configure-check and source-code for gcc's noreturn
>- attribute to assume it is a prefix rather than suffix, matching
>- c11's _Noreturn convention.
>- * modify mk-1st.awk to account for extra-suffix configure option.
>- * build-fix for termsort module when configured with termcap.
>- * modify configure script and makefiles to support ".PHONY" make
>- program feature.
>- * amend libtool configuration to add dependency for install.tic,
>- etc., in ncurses/Makefile on the lower-level libraries.
>- * modify Ada95 source-generation utility to write to a file given as
>- parameter rather than to the standard output, allowing builds with
>- MinGW.
>- * amend tic/infocmp check to allow for the respective tool's
>- absence.
>- * build-fixes for gnat 10.1.1, whose gnatmake drops integration with
>- gprbuild.
>- * correct configure version-check/warning for g++ to allow for 10.x
>+ * change man_db.renames to template, to handle ncurses*-config
>+ script with the --extra-suffix configure option.
>+ * update CF_XOPEN_SOURCE macro, adding variants "gnueabi" and
>+ "gnueabihf" to get _DEFAULT_SOURCE special case, as well as adding
>+ GNU libc suffixes for "abi64", "abin32", "x32" to distinguish it
>+ from other libc flavors.
>+ * work around musl's nonstandard use of feature test macros by
>+ adding a definition for NCURSES_WIDECHAR to the generated ".pc"
>+ and *-config files.
>+ * use "command -v" rather than "type" in Ada95/gen/Makefile.in to
>+ fix a portability issue.

   Library improvements
 
     New features
 
-   There are a few new features:
-     * A   new   (experimental)   driver,   for   the   Windows  Terminal
-       configuration is provided.
-     * A  script is provided which enables OpenBSD users to upgrade their
-       system  to use ncurses 6.3 (OpenBSD developers are also invited to
-       do this).
-
-   Additionally,  to  improve  performance other changes (and extensions)
-   are provided in this release:
-     * modify  lib_mouse.c  to  check  for  out-of-range  button numbers,
-       convert those to position reports.
-     * add sp-funcs for erasewchar, killwchar.
+   There are no new features in this release.
 
     Other improvements
 
-   These are revised features:
-     * modify  wgetnstr,  wgetn_wstr  to  improve compatibility with SVr4
-       curses in its treatment of interrupt and quit characters
-
-   These were done to limit or ultimately deprecate features:
-     * mark wgetch-events feature as deprecated.
-          + prevent  KEY_EVENT  from  appearing  in  curses.h  unless the
-            configure option --enable-wgetch-events is used.
-          + modify   MKkey_defs.sh   to   hide   ncurses'  definition  of
-            KEY_EVENTS to reduce Visual Studio C++ redefinition warnings.
-     * reduce   build-warnings   by   excluding   ncurses-internals  from
-       deprecation warnings.
-
    These are improvements to existing features:
-     * drop symbols GCC_PRINTF and GCC_SCANF from <curses.h>, to simplify
-       use.
-     * apply  gcc  format  attribute  to  prototypes  which use a va_list
-       parameter rather than a "..." variable-length parameter list.
-     * modify  <term.h> so that it is not necessary to include <curses.h>
-       before <term.h>.
-     * provide for wide-characters as background character in wbkgrnd
-     * improve parameter-checking for tparm, adding function _nc_tiparm()
-       to   handle   the  most-used  case,  which  accepts  only  numeric
-       parameters.
-     * use  return-value  from vsnprintf to reallocate as needed to allow
-       for buffers larger than the screen size.
-     * add  another  fflush(stdout) in _nc_flush to handle time-delays in
-       the  middle  of  strings  such  as flash when the application uses
-       low-level calls rather than curses.
+     * modify  delscreen  to  more  effectively delete all windows on the
+       given screen.
+     * modify  wnoutrefresh  to  call  pnoutrefresh if its parameter is a
+       pad,  rather than treating it as an error, and modify new_panel to
+       permit its window-parameter to be a pad
+     * modify  curses_trace()  to  show  the trace-mask as symbols, e.g.,
+       TRACE_ORDINARY, DEBUG_LEVEL(3).
+     * improve  checks  for valid mouse events when an intermediate mouse
+       state is not part of the mousemask specified by the caller
+     * allow extended-color number in opts parameter of wattr_on.
+     * improve _tracecchar_t2 formatting of base+combining character.
+     * trim  out some unwanted linker options from ncurses*config and .pc
+       files seen in Fedora 36+.
+     * improve shell-scripts with shellcheck
+     * improve use of "trap" in shell scripts, using a script.
+     * modify make-tar.sh scripts to make timestamps more predictable.
 
    These are corrections to existing features:
-     * add  a  check  to  guard against repeat_char emitting digits which
-       could  be interpreted as BSD-style padding when --enable-bsdpad is
-       configured.
-     * check  for screen size-change in scr_init and scr_restore, in case
-       a screen dump does not match the current screen dimensions
+     * modify  misc/gen-pkgconfig.in  to  allow  for  the  case where the
+       library  directory  does  not  yet  exist, since this is processed
+       before doing an install
+     * set trailing null on string passed from winsnstr to wins_nwstr.
+     * modify  waddch_literal  to  allow  for double-width base character
+       when merging a combining character
 
   Program improvements
 
    Several improvements were made to the utility programs:
 
-   tabs
+   infocmp
 
-          + implement "+m" option
+          + rewrite  canonical_name  function of infocmp to ensure buffer
+            size
+          + improve  readability  of  long parameterized expressions with
+            the  infocmp  "-f"  option  by  allowing  split before a "%p"
+            marker.
+          + modify   verbose-option   of  infocmp,  tic,  toe  to  enable
+            debug-tracing if that is configured.
 
-   tic
+   tabs
+          limit tab-stop values to max-columns
 
-          + add check for duplicate "use=" clauses.
-          + add  check  to  report  instances where tparm would detect an
-            error in an expression.
-          + add  user-defined  capabilities  from mintty to Caps-ncurses,
-            for checking consistency.
-          + improve warning when oc/op do not mention SGR 39/49 for xterm
-            compatible XT flag.
-          + improve  checks  for  number  of  parameters of smglp, smgrp,
-            smgtp, and smgbp.
-          + improve  "-c"  option  to  validate  the  number  and type of
-            parameters  and  compare  against expected number/type before
-            deciding which set of parameter-lists to use in tparm calls.
-          + improve check for errors detected in tparm.
-          + improve format of output, to ensure that the messages contain
-            only printable text.
-          + modify to eliminate unnecessary "\" to escape ":" in terminfo
-            format.
-          + remove check that assumes that none or both parameterized and
-            non-parameterized margin-setting capabilities are present.
-
-   toe
-
-          + modify  output  of  "toe -as" to show first description found
-            rather than the last.
-          + add  a  check  to ensure that a "termcap file" is text rather
-            than binary.
+   tic
+          add   consistency   check   in   tic  for  u6/u7/u8/u9  and  NQ
+          capabilities.
 
    tput
-
-          + modify to allow multiple commands per line.
-          + improve  parameter-checking  by analyzing all extended string
-            capabilities,  e.g., as used in the Cs and Ms capabilities of
-            the tmux description.
-          + make  warning  messages  consistently  using alias names when
-            those are used, rather than the underlying program's name.
-          + improve   usage   message  for  aliases  such  as  clear,  by
-            eliminating tput-specific portions.
-          + modify  initialization  to  avoid  opening /dev/tty for cases
-            other than reset/init, e.g., for clear.
+          corrected use of original tty-modes in init/reset subcommands
 
     Examples
 
    Along  with  the  library and utilities, improvements were made to the
    ncurses-examples.  Most  of  this  activity  aimed  at  improving  the
-   test-packages.  A few changes are more generally useful, e.g., for the
-   main   ncurses  test-program,  and  for  analyzing  traces  using  the
-   tracemunch script:
-     * add  "-r" option to the dots test-programs, to help with scripting
-       a performance comparison.
-     * build-fix  for  test_opaque,  for  configurations  without  opaque
-       curses structs, e.g., ncurses 5.7.
-     * improve tracemunch logic for "RUN" compaction.
-     * improve tracemunch's coverage of form/menu/panel libraries.
-     * improve  tracemunch's  checking/reporting  the  type for the first
-       parameter, e.g., "WINDOW*" rather than "#1".
-     * modify  tracemunch  and  the panel library to show readable traces
-       for panel- and user-pointers.
+   test-packages:
+     * add  minimal  -h  (usage)  and  -V  (version)  getopt logic to all
+       ncurses-examples programs.
+     * fix an error in "@" command in test/ncurses.c F-menu
+     * add curses_trace to ifdef's for START_TRACE in test/test.priv.h
+     * improve pthread-configuration for test/worm.c
+     * add setlocale call to several test-programs.
+     * workaround  in  test/picsmap.c  for  use of floating point for rgb
+       values by ImageMagick 6.9.11, which appears to use the wrong upper
+       limit.
+     * use  static libraries for AdaCurses test-package for Mageia, since
+       no gprbuild package is available.
+     * install  Ada95  sample  programs  in  libexecdir, adding a wrapper
+       script to invoke those.
+     * install  ncurses-examples programs in libexecdir, adding a wrapper
+       script to invoke those.
 
    There are other new demo/test programs and reusable examples:
 
-   back_ground
-          to exercise the wide-character background functions.
+   test/combine
+          demonstrate combining characters

-          of dup_field.
+   test/test_delwin
+          demonstrate deleting a window
 
-   test_tparm
-          for checking tparm changes.
+   test/test_mouse
+          observe  mouse  events  in  the  raw terminal or parsed ncurses
+          modes
+
+   test/test_unget_wch
+          demonstrate the unget_wch and unget functions

   Interesting bug-fixes
 
-   While  there  were  many bugs fixed during development of ncurses 6.3,
+   While  there  were  many bugs fixed during development of ncurses 6.4,
    only  a  few  (the  reason  for  this release) were both important and
    interesting. Most of the bug-fixes were for local issues which did not
    affect  compatibility across releases. Since those are detailed in the
    NEWS file no elaboration is needed here.
 
-   The interesting bugs were:
-     * modify wbkgd and wbkgrnd to avoid storing a null in the background
-       character, because it may be used in cases where the corresponding
-       0x80 is not treated as a null.
-       This  was  a regression introduced in ncurses 6.2 (reported on the
-       mailing list), for which the workaround was to specify a blank for
-       the background character.
-     * remove  output-related  checks  for  nl/nonl (also reported on the
-       mailing list).
-     * improve  tparm  implementation of %P and %g, more closely matching
-       SVr4  terminfo.  Those  denote  static  and  dynamic  variables in
-       terminfo expressions.
-       Exactly  what those terms meant was never documented before in any
-       implementation of curses, aside from source code. Unlike the other
-       two  fixes,  the  problem  was discovered while studying OpenBSD's
-       version of tset.
+   The  interesting  bugs were those dealing with memory leaks and buffer
+   overflows.  Although  the utilities are designed for text files (which
+   they do properly), some choose to test them with non-text files.
+     * Text  files  contain  no  embedded  nulls.  Also,  they end with a
+       newline.  Feeding tic non-text files exposed a few cases where the
+       program  did  not  check  for  those  issues. As a result, further
+       processing  of the input found limit-checks whose assumptions were
+       invalid.
+     * Fixing  the limit-checks (first) found a problem with tic managing
+       the  list  of  strings  in  a terminal description. In merging two
+       terminal  descriptions  (i.e.,  the  "use="  feature), tic was not
+       allocating  a  complete copy. A quick repair for that introduced a
+       memory leak.
+     * The  checks  for non-text files are improved (i.e., embedded nulls
+       in  the  input  file  will  cause  tic  to  reject  it rather than
+       attempting to process it).
+     * The string allocations in tic are likewise improved.
 
   Configuration changes
 
     Major changes
 
-   There  are  no  major  changes. Several new options were added to ease
-   integration  of packages with systems using different versions of GNAT
-   and ncurses. Also, improvements were made to configure checks.
+   There  are  no  major  changes.  No  new  options  were added. Several
+   improvements were made to configure checks.
 
     Configuration options
 
    There are a few new/modified configure options:
 
-   --enable-fvisibility
-          new  configure  option  and  check  for gcc -fvisibility=hidden
-          feature
-
-   --enable-leaks
-          corrected  to allow turning leak-checking off later in a set of
-          options.
-
-   --enable-stdnoreturn
-          new  configure  option  makes the _Noreturn keyword optional to
-          ease transition.
-
-   --disable-pkg-ldflags
-          revised option also controls whether $LDFLAGS from the build is
-          provided in "-config" and ".pc" files.
-
-   --disable-root-access
-          add  configure  option  which  tells  ncurses  to disallow most
-          file-opens by setuid processes.
-
-   --disable-wattr-macros
-          changed  default  to  help  packagers  who  reuse wide ncursesw
-          header file with non-wide ncurses library.
-
-   --with-pkg-config-libdir
-          revised  option  uses the actual search path from pkg-config or
-          pkgconf using the output from --debug.
-
-   --with-ada-libname
-          --with-form-libname
-          --with-menu-libname
-          --with-panel-libname
-          new several --with-xxx-libname options, to help with pkgsrc
+   --with-abi-version
+          add ABI 7 defaults to configure script.
+
+   --with-caps
+          add   warning   in  configure  script  if  file  specified  for
+          "--with-caps" does not exist.
+
+   --with-manpage-format
+          bzip2 and xz compression are now supported
+
+   --with-xterm-kbs
+          add    check/warning    in    configure    script   if   option
+          "--with-xterm-kbs" is missing or inconsistent
 
   Portability
 
    Many  of  the  portability  changes  are implemented via the configure
    script:
-     * add  a  special case in the configure script to work around one of
-       the build-time breakages reported for OpenBSD 6 here:
-
-     https://www.mail-archive.com/bugs@openbsd.org/msg13200.html
-     * modify configure check for libtool to prevent accidental use of an
-       OpenBSD program which uses the same name.
-     * modify  configuration  checks  for  build-time  tic/infocmp to use
-       AC_CHECK_TOOL. That can still be overridden by --with-tic-path and
-       --with-infocmp-path when fallbacks are used, but even if not using
-       fallbacks, the improved check may help with cross-compiling.
-     * relax modification-time comparison in CF_LINK_FUNCS to allow it to
-       accept link() function with NFS filesystems which change the mtime
-       on the link target, e.g., several BSD systems.
-     * modify  configure  check  for  c89/c99 aliases of clang to use its
-       -std  option instead, because some platforms, in particular macOS,
-       do not provide workable c89/c99 aliases.
-     * modify  CF_NCURSES_CONFIG  to work around Xcode's c99 "-W" option,
-       which conflicts with conventional use for passing linker options.
-     * modify   configure   scripts   to   filter  out  redefinitions  of
-       _XOPEN_SOURCE,  e.g., for NetBSD which generally supports 500, but
-       600 is needed for ncursesw.
+     * amend  configure option's auto-search to account for systems where
+       none of the directories known to pkg-config exist
+     * corrected regex needed for older pkg-config used in Solaris 10
+     * improve  handling of --with-pkg-config-libdir option, allowing for
+       the case where either $PKG_CONFIG_LIBDIR or the option value has a
+       colon-separated list of directories
+     * if   the   --with-pkg-config-libdir   option  is  not  given,  use
+       ${libdir}/pkgconfig as a default
+     * improve search-path check for pkg-config, e.g., for Debian testing
+       which installs pkg-config with architecture-prefixes.
+     * build-fix for cross-compiling to MingW, conditionally add -lssp
+     * improve configure check for getttynam
+     * fixes to build with dietlibc:
+          + add configure check for fpathconf
+          + add   configure   check   for  math  sine/cosine,  needed  in
+            test/tclock, and eliminate pow() from test/hanoi
+          + use wcsnlen as an alternative to wmemchr if it is not found
+     * modify  configure macro CF_BUILD_CC to check if the build-compiler
+       works,  rather  than that it is different from the cross-compiler,
+       e.g.,  to  accommodate  a  compiler  which  can be used for either
+       purpose with different flags
+     * modify  configure/scripts  to work around interference by GNU grep
+       3.8
 
    Here are some of the other portability fixes:
-     * change   configure-check   and   source-code  for  gcc's  noreturn
-       attribute  to  assume  it is a prefix rather than suffix, matching
-       c11's _Noreturn convention.
-     * modify mk-1st.awk to account for extra-suffix configure option.
-     * build-fix for termsort module when configured with termcap.
-     * modify  configure  script  and  makefiles to support ".PHONY" make
-       program feature.
-     * amend  libtool  configuration  to  add dependency for install.tic,
-       etc., in ncurses/Makefile on the lower-level libraries.
-     * modify Ada95 source-generation utility to write to a file given as
-       parameter rather than to the standard output, allowing builds with
-       MinGW.
-     * amend  tic/infocmp  check  to  allow  for  the  respective  tool's
-       absence.
-     * build-fixes for gnat 10.1.1, whose gnatmake drops integration with
-       gprbuild.
-     * correct configure version-check/warning for g++ to allow for 10.x
+     * change  man_db.renames  to  template,  to  handle  ncurses*-config
+       script with the --extra-suffix configure option.
+     * update   CF_XOPEN_SOURCE  macro,  adding  variants  "gnueabi"  and
+       "gnueabihf" to get _DEFAULT_SOURCE special case, as well as adding
+       GNU  libc  suffixes for "abi64", "abin32", "x32" to distinguish it
+       from other libc flavors.
+     * work  around  musl's  nonstandard  use  of  feature test macros by
+       adding  a  definition  for NCURSES_WIDECHAR to the generated ".pc"
+       and *-config files.
+     * use  "command  -v"  rather than "type" in Ada95/gen/Makefile.in to
+       fix a portability issue.

-      character, because it may be used in cases where the

-
-      <p>This was a regression introduced in ncurses 6.2 (<a href=
-      "https://lists.gnu.org/archive/html/bug-ncurses/2020-03/msg00000.html">reported</a>
-      on the mailing list), for which the workaround was to specify
-      a blank for the background character.</p>
+      <p>Text files contain no embedded nulls. Also, they end with
+      a newline. Feeding <strong>tic</strong> non-text files
+      exposed a few cases where the program did not check for those

+      <p>Fixing the limit-checks (first) found a problem with

+      terminal description. In merging two terminal descriptions
+      (i.e., the &ldquo;use=&rdquo; feature), <strong>tic</strong>

-
-      <p>Exactly what those terms meant was never documented before

-      <p>modify configure check for c89/c99 aliases of
-      <em>clang</em> to use its <tt>-std</tt> option instead,
-      because some platforms, in particular macOS, do not provide
