intl: New directory; see intl/ChangeLog for details.

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.
