hdf5/testpar/testphdf5.c
Albert Cheng d76dfb1985 [svn-r6755] Purpose: 
feature

Description:
added test_fapl_mpiposix_dup to verify the MPIPOSIX is making
duplicates of Communicator correctly.

Platforms tested:
Did not h5committested because these are all MPI code and well protected
by HAVE_PARALLEL.
Tested in eirene and modi4, both parallel mode.

Misc. update:
