error in nonblocking.c?

[Jim Edwards]

So this program illustrates the problem:

#include <mpi.h>
#include <stdio.h>
#include <pnetcdf.h>

int main()
{
  printf("%d %d\n",MPI_REQUEST_NULL,NC_REQ_NULL);
}


On Cray systems using pgi compiler:

./a.out
738197504 -1

I can try using NC_REQ_NULL instead of MPI_REQUEST_NULL in my program, but
I'm afraid that's just going to cause this problem to manifest in a
different way.
