The syntax for that has got to be hairy... what I would do is make typedefs
for both types, and then cast one to the other.  So...

    typedef void (*stdio_func)(FILE *file1, FILE *file2);
    typedef void (*voidp_func)(void *pointer1, void *pointer2);

    voidp_func uncasted = /* get this however you get it */;
    stdio_func casted = (stdio_func)uncasted;

    casted((FILE *)argument1, (FILE *)argument2);

I may have gotten that slightly wrong, but hey.  Now if the compiler doesn't
let you do that, you'll have to do something more nasty but I think that
should work.
