Error: Generic subroutine 'mpi_waitall' at (1) is not consistent with
a specific subroutine interface
Issue, 3rd argument of MPI_WAITALL expects an integer array normally,
but this constant is permitted by the standard.
This is with OpenMPI 1.2a1r10186, I can check the details of the
scripts and generated files next week for whatever is the latest
version. But odds are this has not been spotted.
