Hi Tong

actually this feature has always been present; the keywords were
"yes"/"no" which were quite obscure and so I changed them (yes and no
are still available though deprecated).

options have always been mandatory by default in gengetopt and changing
this would break previous code.

What I could do is to add a command line argument that permits
specifying that options are optional by default, what do you think?
