From a66c8bf293d573276250ea4910509a57891c384b Mon Sep 17 00:00:00 2001
From: Scot Breitenfeld <brtnfld@hdfgroup.org>
Date: Mon, 1 Sep 2008 10:25:02 -0500
Subject: [svn-r15570] Description:

Added a test for the availability of intrinsic Fortran function SIZEOF. Sets the global variable FORTRAN_HAVE_SIZEOF depending if SIZEOF is available.
