[PATCH, Fortran] Re-fix PR 31292


The attached patch was built and regression tested
on x86_64-*-freebsd.  This patch partially un-fixes
the patch applied to fix PR fortran/31292.  I've
re-open that PR to track this change.


2009-08-28  Steven G. Kargl <kargl@gcc.gnu.org>

	* gfortran.dg/module_procedure_1.f90: New test.

2009-08-28  Steven G. Kargl <kargl@gcc.gnu.org>

	* fortran/decl.c: Module procedure can appear in PROGRAM and
	subprogram scope.
