I agree.

I think the hack is NOT quick nor adhoc. I believe that it is
very good/sophisticated approach to describe a data structure
which is derived from generic structure. Some C++ compiler do 
this internally to implement class inheritance mechanism. 
In case above, it tells that 'wsdisplay_softc' is a subclass 
of 'device'. Don't you think it is "right" ?
