Hi John

It looks like getopt_long uses ? for its own purposes, see the man page:

If getopt() does not recognize  an  option  character,  it
        prints an error message to stderr, stores the character in
        optopt, and returns `?'.  The calling program may  prevent
        the error message by setting opterr to 0.

so probably, I don't know whether it is possible to do this...

any clue anyone?
