BIND(C) doesn't let us have LOGICAL parameters, so we have to be
creative in how we invoke back-end ompi_*_f() C functions.
Additionally, the mpi_f08 type for MPI_Status presented some
difficulties, too.
See the large comment in
ompi/mpi/fortran/use-mpi-f08/mpi-f-interfaces-bind.h that explains
this in much more detail.
This commit was SVN r29384.
