[PATCH] libgfortran/Makefile.am -- Use M4 environmental variable

Subject: [PATCH] libgfortran/Makefile.am -- Use M4 environmental variable

The attached patch has been bootstrapped in maintainer-mode
and regression tested on amd64-*-freebsd.

Briefly, the problem is that Makefile.am has m4 hardcoded 
in several places.  On FreeBSD, m4 is not GNU m4, and so 
the processing of the files in libgfortran/m4 results in
corrupted files in libgfortran/generated.

The fix is to use $(M4) in place of m4.  The toplevel 
configure correctly finds gm4 (ie, GNU m4) on my system,
and the toplevel Makefile properly sets and exports
M4=gm4.

Note, the testing including the deletion of all files in
libgfortran/generated.  The new generated files under
maintainer-mode are identical to those in svn.

	* Makefile.am: Use $(M4) instead of m4.
	* Makefile.in: Regenerated.

OK for trunk and 4.1?
