I thought it did -- oh well

One reason for not using Unreferenced is that you (now) get problems
with nested generics; in the BCs,

   generic
      type Item is private;
      with function "=" (L, R : Item) return Boolean is <>;
   package BC.Containers is

ends up complaining about the "=" which happens not to be referenced
at this level.

If you use Unreferenced, you get warnings when it is in fact used in
child packages. Hmph. (this is 5.02a1 behaviour, may not be in public
releases)
