Thanks to everyone who replied to this message of mine.  The main
suggestions were: use f2c or use emx (for which there's a port of
g77).

I'm not sure that f2c is what I need.  The thing is that I'm
writing a numerics program in Ada, and compiling using the DJGPP
(MSDOS) version of GNAT, the GNu Ada Translator.  I would like to
use routines from the LAPACK linear algebra library (written in
fortran).  It is possible to access fortran routines from Ada, and
an interface has been written to allow you to use LAPACK routines
from within Ada (its available on the web). I would like to use
this interface, so I need the fortran version of LAPACK.  If I used
f2c then I would have to change the interface package, which I would
rather not do, though it is a possible solution.  The simplest thing
would be to compile LAPACK using g77, and then all the rest will
work.  I can say this with some confidence, since I have done this
using the emx version of GNAT under OS2, and with the emx port of
g77.

Normally emx compiled programs will run under MSDOS as well, but
this is not true for all emx GNAT compiled Ada programs.  My program
is an example.  Otherwise I could have and would have used emx for
everything... (I will probably be shot for saying this on the
DJGPP newsgroup!).

Thanks again for all your help,

Duncan.
