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.
libstdc++-v3/ChangeLog:
* configure: Regenerate.
(The previous iconv-related commit missed the config/iconv.m4 change.)
Original description:
This is the second in a series of patches to make a build with an
in-tree GNU libiconv work as designed.
Currently GDB is the only toolchain component which actually uses an
in-tree libiconv. This patch modifies the common AM_ICONV to use an
in-tree libiconv when present and not already provided by libc.
(GDB's workaround uses an in-tree libiconv even when libc provides
iconv(3); I'm not sure when or why that would be desirable.)
config/ChangeLog:
2015-08-24 Yaakov Selkowitz <yselkowi@redhat.com>
* iconv.m4 (AM_ICONV_LINK): Use in-tree libiconv when present.
