We looked into this matter in substantial detail back in the times of ABI WG (pre-MPI-2.1, I think). Details can be found in https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/AbiWikiPage#no1 .

Is there much technical content beyond the spreadsheet enumerating differences, a lot of which don't matter (init-time constants)? There also seem to be a lot of items labeled as compile-time constants, for which I cannot find the place in the standard where that is required.
