/* These functions solely exist so that the F90 bindings can call a C
   function from Fortran, so we provide all 4 variants.  Specifically,
   the F90 bindings for MPI_WTICK and MPI_WTIME need to call the
   back-end C functions to effect the functionality -- they cannot
   call the back-end F77 functions because there is an overload of
   names and types.  So we create these new functions with different
   names (MPI_WTICK_F90 and MPI_WTIME_F90 vs. MPI_WTICK and MPI_WTIME)
   so that the F90 bindings can call these functions directly.

   Rather than try to be clever with weak symbols, especially since
   the function implementations are 1 line long, it just seemed
   simpler to provide 4 copies of each [1 line] function. */
