Huh?
I've never done that... The "full" form of Fl::args(...) returns an int
value that basically points at the first "non-option" parameter, then I
just parse the filename (or whatever) directly by counting up through
any remaining args...
Dodgy pseudo-code:
int used = Fl::args(...stuff...);
if (used < argc) {
// process reamining switches "by hand"
for(int x = used; x < argc; x++)....
}
That kind of thing.
Always *seems* to have worked OK for me, anyway.
