From f8bfe1cb01fb7079b5307892b004a2c4f5c5ae09 Mon Sep 17 00:00:00 2001
From: Bill Wendling <wendling@ncsa.uiuc.edu>

Subject: [svn-r5112] Purpose: 	Bug Fix Description: 	Parallel Fortran
 wasn't working on Modi4. The tests for parallel 	MPI Fortran were
 failing to find MPI files. Solution: 	Changed the AC_TRY_FLINK() macro so
 that libraries are included 	at the end of the link line so that unresolved
 symbols can be 	found... Platforms tested: 	Modi4
