3) The C implementation allows for certain routines to be implemented as macros (2.6.4, pages 19-20). In particular, the type conversion routines. In that case, there is no external PMPI version. It would be reasonable to allow the same exemption in the case that these routines are implemented by Fortran module procedures (which, from the end result of compilation, would have an effect much like a C macro). I assume that the tools people would not be harmed if these could not be intercepted, as that is already the case for C anyway.

The functions in 17.2.4 do not have Fortran interfaces. They exist only in C.

The macro-allowance for MPI_Wtime and Wtick is only for C.

For MPI_Wtime and MPI_Wtick in Fortran, the usual rules apply. No macro exception.

My answer was 50% a mistake. For the fortran written wrappers, we need these functions also in Fortran and especially the constants MPI_C_COMM_KIND, etc. for the size of the C handles to be able to store them in Fortran integers. I expect that we add this later - it is a minor part.
