From e5d5634456062b7a55700534fe7985d3ec3bd4fc Mon Sep 17 00:00:00 2001
From: Bill Wendling <wendling@ncsa.uiuc.edu>
Date: Mon, 9 Sep 2002 16:51:35 -0500
Subject: [svn-r5916] Purpose:     Bug Fix Description:     Sometimes, we
 needed to pick up a header file in the current build     directory. Solution:
     Added a test to see if the compiler can handle the "-I." option so    
 that it will get that header file. Platforms tested:     Modi4
