Log message:
gettext*: update to 0.22

Version 0.22 - June 2023

* PO file format:
  - When a #: line contains references to file names that contain spaces,
    these file names are surrounded by Unicode characters U+2068 and U+2069.
    This makes it possible to parse such references correctly.

* Improvements for maintainers:
  - The AM_GNU_GETTEXT macro now defines two variables localedir_c and
    localedir_c_make, that can be used in C code or in Makefiles,
    respectively, for representing the value of the --localedir configure
    option.

* Programming languages support:
  - C, C++:
    o xgettext now supports gettext-like functions that take wide strings
      (of type 'const wchar_t *', 'const char16_t *', or 'const char32_t *')
      as arguments.
    o xgettext now recognizes numbers with digit separators, as defined by
      ISO C 23, as tokens.
    o xgettext and msgfmt now recognize the format string directive %b
      (for binary integer output, as defined by ISO C 23) in format strings.
    o xgettext and msgfmt now recognize the argument size specifiers
      w8, w16, w32, w64, wf8, wf16, wf32, wf64 (as defined by ISO C 23)
      in format strings.
    o xgettext and msgfmt now recognize C++ format strings, as defined by
      ISO C++ 20.  They are marked as 'c++-format' in POT and PO files.
      A new example has been added, 'hello-c++20', that illustrates how
      to use these format strings with gettext.
  - Java:
    o The build system and tools now also support Java versions newer than
      Java 11. This is known to work up to Java 20, at least. On the other
      hand, support for old versions of Java (Java 1.5 and GCJ) has been
      dropped.
  - Tcl: xgettext now supports the \x, \u, and \U escapes as defined in
    Tcl 8.6.

* Portability:
  - On systems with musl libc, the *gettext() functions in libc now work
    with MO files generated from PO files with an encoding other than UTF-8.
    To this effect, the msgfmt program now converts the messages to UTF-8
    encoding before storing them in a MO file.  You can prevent this by
    using the msgfmt --no-convert option.
  - On systems with musl libc, the *gettext() functions in libc now work
    with MO files generated from PO files with ISO C 99 <inttypes.h> format
    string directive macros.  To this effect, the msgfmt program pre-expands
    strings with such macros.  You can prevent this by using the msgfmt
    --no-redundancy option.

* xgettext:
  - The xgettext option '--sorted-output' is now deprecated.
  - xgettext input files of type PO that are not all ASCII and not UTF-8
    encoded are now handled correctly.

* The base Unicode standard is now updated to 15.0.0.

* Emacs PO mode:
  Fix an incompatibility with Emacs version 29 or newer.

Log message:
gettext*: update to 0.21.1

Version 0.21.1 - October 2022

* Runtime behaviour:
  - On AIX, locale names with a script or with an uppercase language are now
    supported.
    For example, sr_Cyrl_RS.UTF-8 is treated like sr_RS.UTF-8@cyrillic, and
    EN_US.UTF-8 is treated like en_US.UTF-8.

* The base Unicode standard is now updated to 14.0.0.

* Portability:
  - Building on macOS 11/arm64 is now supported.
  - Building on Linux/powerpc64le with glibc ≥ 2.35 is now supported.

Log message:
gettext*: update to 0.21.

Version 0.21 - July 2020

* Programming languages support:
  - Shell:
    o xgettext now recognizes and ignores 'env' invocations and environment
      variable assignments in front of commands.
  - Java:
    o xgettext now recognizes format strings in the Formatter syntax.  They
      are marked as 'java-printf-format' in POT and PO files.
    o xgettext now recognizes text blocks as string literals.
  - JavaScript:
    xgettext parses JSX expressions more reliably.
  - Ruby:
    o xgettext now supports Ruby.
    o 'msgfmt -c' now verifies the syntax of translations of Ruby format
      strings.

* Runtime behaviour:
  - On native Windows platforms, the directory that contains the message
    catalogs may now contain arbitrary Unicode characters. To make use of
    this feature, use the new function 'wbindtextdomain' instead of
    'bindtextdomain'. It allows to pass a directory name in wchar_t[] encoding.
    Note: 'wbindtextdomain' exists only on native Windows platforms.

* Improvements for translators:
  - When msgfmt writes a MO file, it now does so in such a way that processes
    that are currently using an older copy of the MO file will not crash.

* Libtextstyle:
  - Added support for emitting hyperlinks.
  - New API for doing formatted output.
  - The example programs support the NO_COLOR environment variable.

Log message:
gettext*: update to 0.20.2

Version 0.20.2 - April 2020

* Improvements for maintainers:
  - A dependency bug in po/Makefile.in.in has been fixed.

* Programming languages support:
  - Shell:
    o The programs 'gettext', 'ngettext', when invoked with option -e, now
      expand '\\' and octal escape sequences, instead of swallowing them.
      (Bug present since the beginning.)
    o xgettext now recognizes 'gettext' program invocations with the '-e'
      option, such as
        gettext -e 'some\nstring\n'
  - Python:
    xgettext now assumes a Python source file is in UTF-8 encoding by default,
    as stated in PEP 3120.
  - Desktop Entry:
    The value of the 'Icon' property is no longer extracted into the POT file
    by xgettext.  The documentation explains how to localize icons.

* Runtime behaviour:
  - The interpretation of the language preferences on macOS has been improved,
    especially in the case where a system locale does not exist for the
    combination of the selected primary language and the selected territory.
  - Fixed a multithread-safety bug on Cygwin and native Windows.

Log message:
Also install host-cpu-c-abi.m4 from gettext-tools/gnulib-m4

This fixes errors about gl_HOST_CPU_C_ABI_32BIT not being defined when
running autoreconf, and errors about such a command not being found when
the generated configure script is run.

configure.ac:20: warning: gl_HOST_CPU_C_ABI_32BIT is m4_require'd but not m4_defun'd

Based on only a cursory understanding of autoconf, it seems like all
the files in share/aclocal are always included. Therefore it should be
possible to detect errors like this by running autoconf or autoreconf,
before committing to pkgsrc.

No manual corrections.

Log message:
Update to 0.20.1

Changelog:
Version 0.20.1 - May 2019

* Important bug fix:
  - Fixed a wrong shared library versioning of libintl.so.

Version 0.20 - May 2019

* Support for reproducible builds:
  - msgfmt now eliminates the POT-Creation-Date header field from .mo files.

* Improvements for translators:
  - update-po target in Makefile.in.in now uses msgmerge --previous.

* Improvements for maintainers:
  - msgmerge now has an option --for-msgfmt, that produces a PO file meant
    for use by msgfmt only.  This option saves processing time, in particular
    by omitting fuzzy matching that is not useful in this situation.
  - The .pot file in a 'po' directory is now erased by "make \ 
maintainer-clean".
  - It is now possible to override xgettext options from the po/Makefile.in.in
    through options in XGETTEXT_OPTIONS (declared in po/Makevars).
  - The --intl option of the gettextize program (deprecated since 2010) is
    no longer available. Instead of including the intl sources in your package,
    we suggest making the libintl library an optional prerequisite of your
    package. This will simplify the build system of your package.
  - Accordingly, the Autoconf macro AM_GNU_GETTEXT_INTL_SUBDIR is gone as well.

* Programming languages support:
  - C, C++:
    xgettext now supports strings in u8"..." syntax, as specified in C11
    and C++11.
  - C, C++:
    xgettext now supports 'p'/'P' exponent markers in number tokens, as
    specified in C99 and C++17.
  - C++:
    xgettext now supports underscores in number tokens.
  - C++:
    xgettext now supports single-quotes in number tokens, as specified in
    C++14.
  - Shell:
    o The programs 'gettext', 'ngettext' now support a --context argument.
    o gettext.sh contains new function eval_pgettext and eval_npgettext
      for producing translations of messages with context.
  - Java:
    o xgettext now supports UTF-8 encoded .properties files (a new feature
      of Java 9).
    o The build system and tools now support Java 9, 10, and 11. On the
      other hand, support for old versions of Java (Java 5 and older,
      GCJ 4.2.x and older) has been dropped.
  - Perl:
    o Native support for context functions (pgettext, dpgettext, dcpgettext,
      npgettext, dnpgettext, dcnpgettext).
    o better detection of question mark and slash as operators (as opposed
      to regular expression delimiters).
  - Scheme:
    xgettext now parses the syntax for specialized byte vectors (#u8(...),
    #vu8(...), etc.) correctly.
  - Pascal:
    xgettext can now extract strings from .rsj files, produced by the
    Free Pascal compiler version 3.0.0 or newer.
  - Vala:
    xgettext now parses escape sequences in strings more accurately.
  - JavaScript:
    xgettext now parses template literals correctly.

* Runtime behaviour:
  - The interpretation of the language preferences on macOS has been fixed.
  - Per-thread locales are now also supported on Solaris 11.4.
  - The replacements for the printf()/fprintf()/... functions that are
    provided through <libintl.h> on native Windows and NetBSD are now POSIX
    compliant.  There is no conflict any more between these replacements
    and other possible replacements provided by gnulib or mingw.

* Libtextstyle:
  - This package installs a new library 'libtextstyle', together with a new
    header file <textstyle.h>.  It is a library for styling text output sent
    to a console or terminal emulator.
    Packagers: please see the suggested packaging hints in the file PACKAGING.

Log message:
Do not require _nl_expand_alias to exist, it's a pointless reference to
internals of the GNU libintl implementation. Bump gettext-m4.
