From 0004361cc73d835300d38d65cf3b17d69404083a Mon Sep 17 00:00:00 2001
From: Albert Cheng <acheng@hdfgroup.org>
Date: Tue, 28 Feb 2006 19:27:20 -0500
Subject: [svn-r11991] Purpose: Porting.

Description:
Red Storm's lustre used srand and rand to initialize their user mode
of lustre.  HDF5 also uses srand and that messes up Lustre.

Solution:
Use -DRED_STORM to block out the HDF5 code that calls srand.
This is a temporary fix since Lustre has fixed its code from
calling srand and rand but the fix is not deployed at Red_storm
yet.

Platforms tested:
Tested at Red-Storm.
