aclocal.m4 (AM_WITH_NLS): AC_DEFINE HAVE_LIBINTL_H and USE_INCLUDED_LIBINTL when appropriate.

	* aclocal.m4 (AM_WITH_NLS): AC_DEFINE HAVE_LIBINTL_H and
	USE_INCLUDED_LIBINTL when appropriate.
	* configure, config.in: Regenerate.
	* Makefile.in (datadir): Set to @datadir@.
	(intl.o): Also depend on $(CONFIG_H) and system.h.

	* intl.c: Factor out common gettext initialization sequence.
	(gcc_init_libintl):  New function.
	* intl.h: Include intl/libgnuintl.h if USE_INCLUDED_LIBINTL;
	otherwise include libintl.h if HAVE_LIBINTL_H; otherwise turn
	off NLS.  Add multiple include guard.  No need to #ifdef-guard
	an #undef.  Prototype gcc_init_libintl here.

	* collect2.c (main), cppmain.c (general_init), gcc.c (main),
	gcov.c (main), protoize.c (main), toplev.c (toplev_main):
	Use gcc_init_libintl.

intl:
	* Makefile.in: Don't copy libgnuintl.h anywhere.
