There are MPI_VERSION and MPI_SUBVERSION, but those are in 2.0 and above
only as well. You can probably use their being undefined to mean that the
implementation does not comply to 2.0. I don't know how many 1.1-only MPI
implementations are around anymore, though; there may not be any still in
use (MPI 2.0 was released in 1997).
