Allow GCC use new gettexts macros [2/3]

[Kelley Cook <kcook at gcc dot gnu dot org>]

Here is the first followup patch to the importation of the macros.

Having the new macros allows some cleanup to gcc's handcrafted aclocal.m4.
Whilst there I noticed that GCC_PATH_PROG hasn't been used since Zack 
added libintl, so that was excised too.

Bootstrapped i686-pc-cygwin

OK?
2004-09-03  Kelley Cook  <kcook@gcc.gnu.org>

	* aclocal.m4: Add in gettext's m4 includes.
	(AC_ICONV, AC_LCMESSAGES, GCC_PATH_PROG): Remove.
	* configure.ac: Add in check for iconv.m4
	* configure: Regenerate.
