Hello,

I have a problem: NetCDF 4.0.1 adds the following lines to netcdf.h
(HDF5 is, in fact, built without parallel I/O support.):

===
/* These defs added by netCDF configure because parallel HDF5 is not
present. */
#define MPI_Comm int
#define MPI_Info int
#define MPI_COMM_WORLD 0
#define MPI_INFO_NULL 0
===

This sounds familiar.  Are you having the same problem as I was a few
years back?

I think I am.

I was trying to compile with MPICH2, not OpenMPI, but I was getting
stuck on redefining MPI_Comm and MPI_Info as well.

Thanks for pointing this out.
