Yes, 1 or 2.
I really don't like uppercase because it is usually "reserved" for 
(preprocessor) macros.

OK, I don't mind it was just an idea to move from the original simple enum 
prefixes.

OK, I'll check it if I have a little time.

Last when I was dealing with gengetopt's source refactoring I had a feeling 
that using type-specific callbacks may be a good approach. I mean different 
callbacks for options of type integer, floats and string. But now I don't know 
how far you have got in refactoring.
