   // Microsoft Visual C++
   #if !defined (_MSC_FULL_VER)
   #    define BOOST_CXX_MSVC_BUILD 0
   #else
     // how many digits does the build number have?

   #    define BOOST_CXX_MSVC_BUILD (_MSC_FULL_VER % 100000) // five digits
   # else
   #   error "Cannot determine build number from _MSC_FULL_VER"
   # endif
   #endif
   #define BOOST_CXX_MSVC BOOST_VERSION_NUMBER( \
       _MSC_VER/100-6,                          \
       _MSC_VER%100,                            \
       BOOST_CXX_MSVC_BUILD)

One should be able to use the _MSC_FULL_VER value.
