These routines are not implemented in MPICH releases before MPICH2.
Obviously, this is a problem for those of us for whom MPICH2 is not yet
a viable option performance-wise.  Attached is a patch which makes
Parallel NetCDF more friendly to MPICH1 and also fixes some warnings on
malloc()'s of arrays of MPI_Request's.
