In our case, all of our Fortran is 77 so we always invoke the Fortran 
compiler to preprocess the Fortran source with the C preprocessor 
(cpp).  This allows use to use #define and #include in our Fortran 
source.  Naturally this won't work in all cases.

I'll give this a try and let you know how it goes.
