In MPI-1, the Fortran interface for MPI_Type_hvector did not use an address-size argument for stride, whereas the C interface did. This was fixed in MPI-2 by defining a new function MPI_Type_create_vector and deprecating the old one. Only the "h" version and type_struct needed to be fixed this way. Rajeev

Some of the MPI type creators were deprecated, such as MPI_Type_hvector, replaced with MPI_Type_create_xxx. Why weren't others like MPI_Type_vector similarly updated to MPI_Type_create_vector?

Should we clean house a bit and get some consistency in the MPI 3 standard API naming?
