From 7f5b00c2152033b07f5f1ab99863235cbce8048f Mon Sep 17 00:00:00 2001
From: Bill Wendling <wendling@ncsa.uiuc.edu>
Date: Mon, 9 Jul 2001 12:50:12 -0500
Subject: [svn-r4156] Purpose:     Fix Description:     I didn't put the zlib
 fix into the 1.4 branch. Solution:     Put the fix into the configure to
 clear the cache so that configure     always checks for zlib in the fortran/
 directory so that it'll be put     in the LFlags macro.
