Add gettext support.

Mon Jan 15 21:12:49 2001  Owen Taylor  <otaylor@redhat.com>

        * configure.in acconfig.h glibintl.h gutils.c
	po/{Makefile.in.in,POTFILES.in,po2tbl.in}: Add gettext
	support.

	* glib-gettext.m4 acinclude.m4: Clean up the GTK+ gettext macros
	some more and put them in this file, though they also need
	to be included in acinclude.m4 due to the brokeness of
	aclocal.

	* gspawn.c gspawn-win32.c gutf8.c gconvert.c gfileutils.c
	gshell.c: Remove dummy _() #defines, include glibintl.m4.
