hdf5/testpar/t_fphdf5.c
Bill Wendling 918b657ddd [svn-r7701] Purpose: 
Update

Description:
    Added test for FPHDF5 to the testpar/ directory. If you specify
    --enable-fphdf5 during configuration, it'll run this test during a
    "make check".

Platforms tested:
    Linux (FPHDF5 specific).

Misc. update:
