(The story is that _CPPLIB_VER is a Dinkumware macro, and Microsoft doesn't promise that we'll always keep it, or remember to update it for each major version. _MSC_VER is the compiler major version macro, which for customers outside Microsoft always corresponds 1:1 to the STL implementation.)

 From memory, there were some folks using MSVC with updated Dinkumware
libraries, in which case Boost.Config broke if we checked _MSC_VER.
