Perhaps there should.  But note that a Fortran compiler might use an
entirely different run-time environment (e.g., perhaps no stack at all)
than a C compiler, even on the same machine.

It is clear that no one language standard can constrain any *other*
language, and that therefore no one standard (for Fortran, C, PL/I,
APL, Lisp, DDL, rog-o-matic, or whatever) can require inter-language
calls.  It requires an inter-language standard to do this.

Good luck on getting together an inter-language standard ... you will
certainly need it.
