I see.. Different story then :-)

Indeed that is a problem with the current version number. And indeed right
now there's no way to get the real version number of the compiler as
detected by b2. Although for msvc the version number are fixed and you
can't alter them like you can for gcc toolset. I.e. it's always going to be
"msvc-7.1". So I created an issue for adding that <>.
