Really? I always thought that this flag discussed how to convert F77
MPI handles to C handles (some MPI implementations use integers for
MPI handles in C, so there's no conversion necessary, but LAM and
Open MPI use pointers, so using the MPI_*_f2c() functions are
necessary). Hence, it's not specific to a given fortran compiler.
But I could be completely misunderstanding this value...
UTK: can you confirm/deny both of these values? (I do not claim to
be a BLACS expert...)
