using a boost.intrusive header with c++0x support, gcc-4.6 stops with the
following error. the same code compiles fine with gcc-4.5 and without c++0x
support


/usr/include/boost/intrusive/list.hpp: In static member function âstatic
boost::intrusive::list_impl<Config>&
boost::intrusive::list_impl<Config>::priv_container_from_end_iterator(const
