when the compiler has already seen a template class named "value" (it tries
to keep track of class templates in order to not require typename).
You can work around the problem by replacing the above with
enum
    {
        msvc71_wknd_ = ( BOOST_MPL_AUX_VALUE_WKND(T2)::value
                        > BOOST_MPL_AUX_VALUE_WKND(T1)::value )
    };
Another workaround is to replace it with

     enum
     {
         msvc71_wknd_ =  BOOST_MPL_AUX_VALUE_WKND(T1)::value
                         < BOOST_MPL_AUX_VALUE_WKND(T2)::value
     };

Somehow the parenthesis make the difference... weird.
I submitted a bug report last night.
