It sounds like this one needs a special case for the current MPICH bug. That isn’t hard and I can do that, Jeff, if you don’t want to. Let me know. It will need a configure test for the suspect cases.

MPICH decided to follow the same convention as MPI_Type_create_struct with the const additions. Open MPI decided to keep the old prototypes as is.

We'll figure out what to do about that internally, but that's not going to be a quick change because of ABI and other such stuff.
