I thought that NEC provided functions written in C that are callable
directly via Fortran. The code in the C MPI_Send and the "Fortran"
MPI_SEND was essentially the same C code -- the point of the design
was the avoid a second function call from the Fortran API functions.
Do we really need to worry about [real] native Fortran MPI
