Hi all. I'm using getopt_long_only() in a project and I'd like to able to use it in a case insensitive manner. I've done a fair bit of googling on the subject but I can't find a thing. As a hack I could just lower the case of the command line string prior to processing, but if I could manage it in a more graceful way that would be preferable. A portable stand-alone command line parser (preferably similar to getopt) that permits this would also be good. Any help is appreciated. Thanks, Ehtyar.
