That may all be true, but I think it is a different thing, and is not what I am proposing.

To be clear: WTICK/WTIME were explicitly allowed to be macros *in C* ever since MPI-2.0.  I am not changing that in my proposal (now ticket #428).  #428 only fixes MPI_SIZEOF and the status-conversion functions.

Someone else is free to propose the ability of WTICK/WTIME to be inlined in Fortran, but that requires a little more spelunking in history to know why that was done in MPI-2... which I do not have time for at the moment.
