well, to contradict my own position from previously, this function was

Thanks

I assume you meant "Not sure what this means for f77 applications".
This is why I didn't attempt a patch - the solution to this was
not immediately obvious to me due to the Fortran 77 compatibility
issue.
The functions that have the MPI_Fint casts are C functions, so
at the very least, if MPI_Offset is a 64 bit int, then these functions
should not be casting them to 32-bit ints, otherwise we have
two broken interfaces (F77 and F90) instead of one (F77).

There is a hint for F77 users at the bottom of the page. It suggests
to use INTEGER*MPI_OFFSET_KIND as type for the SIZE. I guess if we
cast it correctly, and the users follow the MPI specification, this
should work.
Please tell me you are joking?
No, that will NOT work, in general. Firstly, the xxx in INTEGER*xxx was
introduced in Fortran IV as a digit string and not a constant, and all
of the compilers I know of still do that. Secondly, it is NOT always
aligned with the KIND values, and there is no implication in any document
I know of that it should be.
