Well, I would not call myself an expert either and I don't know if this post 
should affect your update plans.
Anyway: since you seem to have that new compiler installed I would find it 
interesting to know whether the "tuple testers" in the detail directory of 
Boost.Preprocessor work as expected now (they did not work with older versions of 
the Borland preprocessor):

     #include <boost/preprocessor/detail/is_nullary.hpp>
     #include <boost/preprocessor/detail/is_unary.hpp>
     #include <boost/preprocessor/detail/is_binary.hpp>

     BOOST_PP_IS_NULLARY(foo)      // should expand to 0
     BOOST_PP_IS_UNARY(foo)        // should expand to 0
     BOOST_PP_IS_BINARY(foo)       // should expand to 0

     BOOST_PP_IS_NULLARY(())       // should expand to 1
     BOOST_PP_IS_UNARY((foo))      // should expand to 1
     BOOST_PP_IS_BINARY((foo,bar)) // should expand to 1
