--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> 2010-11-01 12:36:45 UTC --- Attributes were still in the FCD, and are still in the current draft, but might be removed. Override control may not be done by attributes, but will be present in C++0x in some form, see http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3151.html and http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3163.pdf for the latest proposals.
