Thus the structure will still use the space of an int and only use the number of bits specified in that int.  Also the RCI IE has spare bits that could conceivably and conveniently be passed in the same int if it made sense.  Therefore, it would be better to simply make it an int and not place any restrictions on the value passed from libpri.

Makes sense to me.  Done.
