Granted, an error, not a clarification. Does any implementation do this now (define Type_status in mpif.h/mpi module)? If not, it is easier to consider this an error.

Open MPI does not -- this issue came up a few months ago in the Open MPI project and just re-surfaced again. It led me to a deeper read of MPI-3.1 about the definition of these functions. I don't immediately see it in MPICH, either. -- Jeff Squyres [email protected]
