On Darwin10 it's possible to make a 32b PPC build using the

Darwin9 crts (for exes, dylibs and bundles). This adds the

* sem_res.adb (Resolve): IF an entity reference is overloaded
because its type has an Implicit_Dereference aspect, we must

handle uses of the aspect in container handling and iteration,
but not more generally.
