Thanks very much! I wouldn't have dreamt that convincing 7.0 to compile it will be soooo easy! Best Regards, Andreas P.S. Is it a good idea to use mpl::aux::msvc_eti_base on all platforms (on conforming compilers I'd expect it to "call" mpl::identity) or should I #ifdef my way around it? _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
