Hmm. Well, if it's non-conforming we probably shouldn't use it. If
it's just a vc bug, we could do something like

     #ifndef BOOST_STRICT_CONFIG
     # ifdef BOOST_MSVC
     #  define BOOST_WORKAROUND(symbol, test) BOOST_DEFINED_##symbol && symbol test
     #  define BOOST_DEFINED_BOOST_MSVC BOOST_MSVC
     #  define BOOST_DEFINED_BOOST_DINKUMWARE_STDLIB BOOST_DINKUMWARE_STDLIB
        ...
     # else
     #  define BOOST_WORKAROUND(symbol, test) (defined(symbol) && symbol test)
     #else
     # define BOOST_WORKAROUND(symbol, test) 0
     #endif
