A fair point.

Heh, but you could look at this as your MPI implementation gently prodding you to stop using ancient Fortran dialects.  ;-)  (yes, I know, I know... it's just a joke)

However, keep in mind that OMPI (and MPICH) only have mpif77 and mpif90 -- not mpif95, mpif03, or mpif08.  

Just to be clear: are you saying that, for example, on IBM platforms, MPICH's mpif77 and mpif90 enforce F77 and F90 language compliance?
