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).
