Ok, then getopt need to be fixed.

But it seems bad style to replace a system getopt unless there is
something wrong with it?  In the POSIX sense, I mean.

(Below I'm assuming the code Alex posted only exploited GNU specific
features.  If the code only relied on POSIX semantics, it seems that a
smaller fix to getopt.m4 is sufficient.)

Perhaps we can create two modules: getopt and getopt-gnu.  This is
similar to getpass and getpass-gnu.  The getopt module would only be
enabled if POSIX compliant getopt and getopt_long_only are missing.
The getopt-gnu would be enabled when the system provided functions
don't implement the GNU interface of getopt*.

Thoughts?
