On some systems, the global structure works (Berkeley).

On at least SILICON GRAPHICS, a structure has to be defined in C
and the common block in Fortran and a subroutine accepting a pointer
to the first type in the common area has to be written in Fortran
and called by C with the pointer to the structure.  In addition,
a bridge routine has to be created in order to call Fortran from C.

Good Luck.
