Does a tool exist to generate Fortran callable C routines from C source
code.  The likely compilers would be f77 or gf77 (Greenhills) for 680x0.
I've begun writing an awk[1] program but suspect there may be painful
intricacies down the line.  A very simple example of what I need:

	int foobar (x)
	int x;
	{
	/* whatever */
	}

becomes (I think):

	int foobar_ (x)
	int *x;
	{
	external int foobar ();

	return (foobar (*x));
	}

Any advice/leads/source would be greatly appreciated.  Any tips
about calling Fortran routines from C would also be useful. THANKS!

[1] Hmmm, why isn't there a comp.lang.awk?
