[Mpi-22] MPI-2.1 ambiguity?

[Jeff Squyres]

I will file a proposal about this if there is a problem, but I wanted  
to ask the group before I did so.  In the changelog for MPI-2.1:

2. Section 3.2.2 on page 27, Section 16.1.6 on page 453, and Annex A.1  
on page 491.
MPI_LONG_LONG_INT, MPI_LONG_LONG (as synonym), MPI_UNSIGNED_LONG_LONG,
MPI_SIGNED_CHAR, and MPI_WCHAR are moved from optional to official and  
they
are therefore defined for all three language bindings.

Note that it says that these C datatype names must be in all three  
language bindings.

Are C MPI datatypes supposed to be available in Fortran?  I looked in  
mpif.h for Open MPI, MPICH2, HP MPI, and Intel MPI, and I didn't see C  
MPI datatypes in there (e.g., MPI_INT and MPI_FLOAT).

So:

- is there language somewhere in MPI that says that C datatypes are  
not supposed to be in mpif.h? (and therefore the MPI-2.1 changelog is  
wrong)

or

- are all 4 of the above MPI's wrong for not including the C datatypes  
in mpif.h?
