Okay, I *must* have been tired -- yes that's it... :)

I missed entirely that with POPT_ARG_NONE you could still put a pointer in for *arg to capture a value.

Thanks.

You are trying to use a getopt-style while() loop to process the arguments 
that have already been 100% processed by gnome_init_with_popt_table.

If you pass the -d option, immediately after the
gnome_init_with_popt_table() call the debugFlags variable will set. If you
were to stick the address of an int variable in the entry for the simulate
option, popt would set it to 1 if that option was passed. And so it
goes...

If you need to do more involved processing of arguments, you can get popt
to call callbacks and such for each argument. The gnome1 popt setup
doesn't support the getopt-style loop, but there are plenty of other ways
to accomplish the same thing if you investigate popt enough.
