:-( Is it a commercial program, or something you developed internally?

Unfortunately, I don't. I use cfortran.h to mix C and Fortran, and I
write the header files necessary by hand.

It is a header file that allows a portable mixing between Fortran-77
and C (C++).

It needs that you write for every Fortran function which should be
callable by C something like

#define MYFUNC(A,B,C) CCALLSFFUN3(MYFUNC, myfunc, INT, STRING, PINT, A, B, C)

when the F77 function is like

     FUNCTION MYFUNC(A, B, C)
     INTEGER A
     CHARACTER*(*) B
     INTEGER C
C    ...

As far as I know, there is no tool available that is able to create
the C header file automatically. 

Is there anything I could use for documentation in such an
environment? How difficult is it to add Fortran to doxygen?
