[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.
