Thanks for reporting.  I just fixed it in the CVS.

That is the usual way of doing thing.  Some options are to be passed
to the GUI and the usual way to handle this is by letting the GUI init
fucntion remove the args from the array and then continue with the
application's option parsing.  The advantage is that the GUI lib may
add new GUI options to all applications without the need to change the
applications proper.

Adding an extra hook to parse "--help" is theoretically possible but
not good style.  Anyway the Xlibn error stuff should go to stderr and
--help and ---version go to stdout.

Thanks,
