[mpich-discuss] 'nonblocking' test needs revision

I'm using the MPICH BVT tests to test a build of OpenMPI. While doing 
that, I find that 'nonblocking.c' needs to be revised as follows
//    int *types = NULL;
    MPI_Datatype *types = NULL;

//    types = malloc(size * sizeof(int));
    types = malloc(size * sizeof(MPI_Datatype));

Presumably it works as-is for mpich because MPI_Datatype is an 'int'; but 
this isn't the case for other MPI implementations. Would one of the mpich 
developers care to make these changes to the source code ?
