Check that MPI_xxxx_c2f, applied to the same object several times,
yields the same handle. We do this because when MPI handles in
C are a different length than those in Fortran, care needs to
be exercised to ensure that the mapping from one to another is unique.
(Test added to test a potential problem in ROMIO for handling MPI_File
on 64-bit systems)
