[MPI3 Fortran] MPI_INIT issues

As fas as I see,
the MPI routines guarantee to work on all MPI processes,
whereas the Fortran routines are guaranteed only in a 
sequential program.

If you are doing slides, then please show the Fortran routine
functionality (e.g., the INOUT quality of  a length argument)
and compare it to the proposed MPI routine.
They should be identical (i.e. least surprise).
This would help the audience to see that the interface is okay.

Best regards
Rolf
