[gtkada] Gtk.Containers and derived types

[Fraser Wilson]

I guess you're using

   Gtk.Container.Remove (Box, Item);

In Ada 95, this should be

   Gtk.Box.Remove (Box, Item);

In Ada 2005, just use
   Box.Remove (Item);

(The box Remove procedure is implicitly declared in Gtk.Box, which is why
you get this correct, but unhelpful, error message).

cheers,
Fraser.
