I've got to raise a concern here. If we start defining MPI datatypes to be C++ types then how will an implementation support that with only a C compiler? I thought the point of 281 was to eradicate C++ from the standard (and start over later if C++ was to be defined in the standard).

There are a few C++-specific datatypes for which it would be worth introducing new C datatypes (e.g., MPI_CXX_COMPLEX).  It's too bad that no one realized this until now, because this won't make the MPI-3 deadline.  But it could be part of MPI-3.1 or errata, or some such.
