Some more data from HOL-IMP and HOL-MicroJava: the former was trivial to fix (patch in main repository already). MJ after removing an unused lemma only seems to require a working Library/More_Set.thy to get through (haven't done anything about that one).

At least for applications in that style, I don't think we need to expect much pain for going back to a separate set type.
