[mpich-discuss] How can we generate source files corresponding to f77 binding

[Rajeev Thakur]

All the @MPI_F77_LONG@ like things are filled in by configure. That's what GNU autoconf does.

There are options to buildiface to generate variations on the interfaces; though it is not yet in the distribution, I'm working on a version to handle the case where Fortran INTEGERs are different in size than C ints (which some applications still want).
