top:
* intl: New directory; see intl/ChangeLog for details.
* ABOUT-NLS, config.rpath: Import from gettext 0.12.1.
* Makefile.tpl: all-gcc depends on maybe-all-intl.
* Makefile.in: Regenerate.
config:
* gettext.m4: New file - copy of gettext.m4 from binutils
CVS, with added AC_ISC_POSIX macro from gcc/aclocal.m4.
gcc:
* ABOUT-NLS: Delete.
* intl: Delete entire directory.
* aclocal.m4: Include ../config/gettext.m4. Delete
AC_ISC_POSIX, AM_LANGINFO_CODESET, jm_GLIBC21, AM_LC_MESSAGES,
AM_PATH_PROG_WITH_TEST, AM_WITH_NLS, and AM_GNU_GETTEXT.
* configure.in: Use CY_GNU_GETTEXT, not AM_GNU_GETTEXT.
Remove intl/Makefile from all_outputs.
* configure, config.in: Regenerate.
* Makefile.in: Expunge all references to intl subdirectory.
Add -I../intl to INCLUDES.
* intl.h: Include libintl.h if and only if ENABLE_NLS is defined.
intl:
* Makefile.in: Remove unnecessary capabilities for
installation, build of shared libraries, generation of
distribution tarballs, etc. Fix all the places that rely on
the parent directory. Don't generate libgnuintl.h from
anything; do generate $(objdir)/libintl.h from libgnuintl.h if
necessary. Adjust DEFS for use of config.h.
* libgnuintl.h.in: Rename libgnuintl.h.
* README: New file.
* config.charset, ref-add.sin, ref-del.sin: Delete (unused).
* COPYING.LIB-2.0, COPYING.LIB-2.1: Delete (redundant).
* aclocal.m4: New; generated per instructions in gettext manual.
* configure.in: New; written from scratch for this configuration.
* configure, config.h.in: Generated.
contrib:
* gcc_update: Remove gcc/intl/plural.c from list.
Add new generated files intl/plural.c, intl/configure,
intl/config.h.in.
