[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.
