This code compiles with current gcc (2.96) configured with --enable-libstdcxx-v3,
because in the new c++ library, the following assignement operator was added to 
the auto_ptr class

    auto_ptr& operator=(auto_ptr_ref<X> r) throw();

This is not in the current standard, but is in accordance with proposed resolution to
the library defect report #127 
(see http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/lwg-active.html#127).

Best regards,
Artem.
