Hello,

I would like to find a way to allow_unregistered program_options, as well as specify cls::unix_style ^ cls::allow_short, where cls is po::command_line_style.

The code I've got here doesn't seem to like unrecognized ones:

//vis_ are my visible options, vars_ is my variable map.

    po::store(parse_command_line(argc, argv, vis_,
            cls::unix_style ^ cls::allow_short), vars_);
    po::notify(vars_);

And then a slight variation with apparently a way to do this (untested), how to specify that cls?

    po::parsed_options parsed_ = po::command_line_parser(argc, argv)
        .options(vis_).allow_unregistered().run();
