Should we switch from using getopt() to using getopt_long()? It's
available in most Linux distributions (as it's in glibc), newer versions
of most if not all *BSDs as well as Mac OS X, and newer versions of
Solaris, and we could supply the glibc version on platforms that lack it
(we're already supplying the glibc version of getopt() on Windows, which
is probably the only platform we run on that lacks getopt()).
That would let us have multi-character strings for options, and still
support single-character aliases for the options we already support (and
add single-character aliases for options we think would be frequently used).
Or, alternatively, now that we've dropped support for GLib 1.2[.x], we
could just use the GOptions command-line parser in GLib, although that
would also require that we drop support for GLib 2.x prior to GLib 2.6.
For Wireshark, that *might* let us use gtk_init_with_args() rather
than gtk_init(), if we do the main argument parsing at the time we're
calling gtk_init(), although we still have to do the "pre-parse" before
calling gtk_init_with_args().
