contrib/ChangeLog:

	* download_prerequisites
	<arg parse>: Parse --only-gettext.
	(echo_archives): Check only_gettext and stop early if true.
	(helptext): Document --only-gettext.

This patch updates gettext.m4 and related .m4 files and adds
gettext-runtime as a gmp/mpfr/... style host library, allowing newer
libintl to be used.

This patch /does not/ add build-time tools required for
internationalizing (msgfmt et al), instead, it just updates the runtime
library.  The result should be a distribution that acts exactly the same
when a copy of gettext is present, and disables internationalization
otherwise.

There should be no changes in behavior when gettext is included in-tree.
When gettext is not included in tree, nor available on the system, the
programs will be built without localization.

ChangeLog:

	PR bootstrap/12596
	* .gitignore: Add '/gettext*'.
	* configure.ac (host_libs): Replace intl with gettext.
	(hbaseargs, bbaseargs, baseargs): Split baseargs into
	{h,b}baseargs.
	(skip_barg): New flag.  Skips appending current flag to
	bbaseargs.
	<library exemptions>: Exempt --with-libintl-{type,prefix} from
	target and build machine argument passing.
	* configure: Regenerate.
	* Makefile.def (host_modules): Replace intl module with gettext
	module.
	(configure-ld): Depend on configure-gettext.
	* Makefile.in: Regenerate.

config/ChangeLog:

	* intlmacosx.m4: Import from gettext-0.22 (serial 8).
	* gettext.m4: Sync with gettext-0.22 (serial 77).
	* gettext-sister.m4 (ZW_GNU_GETTEXT_SISTER_DIR): Load gettext's
	uninstalled-config.sh, or call AM_GNU_GETTEXT if missing.
	* iconv.m4: Sync with gettext-0.22 (serial 26).

contrib/ChangeLog:

	* prerequisites.sha512: Add gettext.
	* prerequisites.md5: Add gettext.
	* download_prerequisites: Add gettext.

gcc/ChangeLog:

	* configure: Regenerate.
	* aclocal.m4: Regenerate.
	* Makefile.in (LIBDEPS): Remove (potential) ./ prefix from
	LIBINTL_DEP.
	* doc/install.texi: Document new (notable) flags added by the
	optional gettext tree and by AM_GNU_GETTEXT.  Document libintl/libc
	with gettext dependency.

libcpp/ChangeLog:

	* configure: Regenerate.
	* aclocal.m4: Regenerate.

	* configure: Regenerate.

contrib/
	* download_prerequisites: Update to gmp-6.2.1, mpfr-4.1.0,
	mpc-1.2.1 and isl-0.24.
	* prerequisites.md5: Update hash.
	* prerequisites.sha512: Likewise.

Since == is not portable, it is better to use = in contrib/
download_prerequisites.  The only place == was used is inside
the function md5_check which is used only on Mac OS X.

Tested on Mac OS X as:
./contrib/download_prerequisites --md5
Both with all files having the correct checksum and one with a broken one.

contrib/ChangeLog:

	* download_prerequisites (md5_check): Replace == inside
	test with = to be more portable.

There are a few problems with download_prerequisites are
described in PR 82704.  The first is on busy-box version of
shasum and md5sum the extended option --check don't exist
so just use -c.  The second issue is the code for which
shasum program to use is included twice and is different.
So move which program to use for the checksum after argument
parsing.  The last issue is --md5 option has been broken for
sometime now as the program is named md5sum and not just md5.
Nobody updated switch table to be correct.

contrib/ChangeLog:

	PR other/82704
	* download_prerequisites: Fix issues with --md5 and
	--sha512 options.

This updates the mpfr version to 3.1.6 which is the last bugfix
release from the 3.1.x series and avoids printing the version
is buggy but acceptable from our configury.
