To my knowledge, these are the platforms it fails on: #if BOOST_WORKAROUND(__GNUC__, == 2 && __GNUC_MINOR__ == 95) \ || BOOST_WORKAROUND(__MWERKS__, <= 0x2407) \ || BOOST_WORKAROUND(__BORLANDC__, BOOST_TESTED_AT(0x551)) no has_xxx support #endif -- Dave Abrahams Boost Consulting www.boost-consulting.com _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
