I did a google search of MPI_FUNDAMENTAL on www.mpi-forum.org and I didn't
see it mentioned in the standard except on couple archived emails. So
I don't think MPI_FUNDAMENTAL is in the standard.  (BTW, I couldn't 
find MPI_FUNDAMENTAL defined in the mpi.h in the latest MPICH2, MPICH1 and 
OpenMPI)

Could you use MPI_COMMBINER_NAMED instead MPI_FUNDAMENTAL ? see
