Hi, I would like to propose the addition of a new config macro to Boost.Config: BOOST_USING_OLD_STYLE_IOSTREAMS
A (possibly incomplete) implementation is: #if defined(__GNUC__) && (__GNUC__ < 3) && !defined(__STL_USE_NEW_IOSTREAMS) || defined(_MSC_VER) && (_MSC_VER < 1300) #define BOOST_USING_OLD_STYLE_IOSTREAMS #endif Regards Gustavo Guerra _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
