This is a bug in mpinetcdf.c .  The MPI standard allows the MPI handles to 
be pointers (in fact, they need not be defined until after MPI_Init 
returns).  Most implementations prefer to use compile-time constants (MPICH 
switched from pointers to constants some time ago), but LAM's choice is 
within the standard.  In this case, the chain-of-ifs is probably the best 
solution.  For the x_putn_xxx routines, we should consider passing the 
NC_<type> name instead of the MPI datatype, since the NC_<type> is 
guaranteed to be a compile-time constant suitable for a switch statemetn.
