As one of the lesser gods who voted the other way, the current draft
of MPI has the function MPI_TYPE_INDEXED_BLOCK where the blocklengths
are assumed to be 1.  The call for this function was heard and is
answered (by a close vote!).  Keep in mind that the MPI document is
still under development so things can change.
