This is (pedantically speaking) a bug in the new throw_exception (it doesn't allow throwing non-class types) that exposes a bug in the serialization library (it throws the invalid_class_name enum value directly instead of constructing an archive_exception from it). It might be a good idea to retain the throw_exception "bug" as a feature to catch similar mistakes. Throwing a non-class is rarely intentional. I've applied the obvious fix to the xml_(w)iarchive_impl.ipp that allows me to build the serialization library. I'm sure that Robert will correct me if I've done something wrong. :-)
