   NEW_POINTERS enables using ints for the MPI objects instead of addresses.
   This is required by MPI 1.1, particularly for Fortran (also for C, 
   since you can now have "constant" values for things like MPI_INT, and
   they are stronger than "constant between MPI_INIT and MPI_FINALIZE".
   For example, we might want to allow MPI_INT as a case label.

   NEW_POINTERS is the default; I'm purging all code that doesn't use
   NEW_POINTERS from the source.
