-- on its own might indicate the end of arguments, but that's quite
different from --foo=bar. Guideline 10 of the above surely only refers
to -- as an entire argument, not to -- as the first two characters of an
argument. If your getopt treats *any* -- as the end of options then I
think it is broken (complain to your vendor ;-) ). And the answer is
known - use the one we have in src/port.
