I don't think you even need the c wrapper. I havedone this in the past using
wrappers in fortran similar to the one below, which works on Lahey Fortran.
This work on IVF and CVF too, only the DLL_EXPORT statement varies between
the compilers. Don't forget to tell youe fortran compiler to create a dll
insted of lib.

Cheers, Haje.

REAL*4 FUNCTION SUM_ARRAY(ARGC, ARGV)

DLL_EXPORT SUM_ARRAY

INTEGER*4 ARGC, ARGV(*)

J=LOC(ARGC)

CALL SUM_ARRAY1(%VAL(ARGV(1)),%VAL(ARGV(2)),%VAL(ARGV(3)))

SUM_ARRAY=9.9

RETURN

END
