Hi Michael!

Module me not being a lawyer by a LOOONG shot - I think the answer is
something like this:

1. Squeak 1.1: Apache 2  (and SqueakL and APSL but so what)
2. Modifications since then and signed: MIT
3. Modifications since then and not signed: SqueakL

Imagining #3 above does not exist - then all code under #2 can trivially
be relicensed by you under Apache 2 - since MIT allows that. Tada - full
Apache 2.

But the crux is #3 (as for example - Disney code). Anyone: correct me if
I am wrong.
