Microsoft has defined _MSC_VER as follows:

Visual Studio 6:           _MSC_VER=1200
Visual Studio .NET 2002:   _MSC_VER=1300
Visual Studio .NET 2003:   _MSC_VER=1310
Visual Studio 2005:        _MSC_VER=1400
Visual Studio 2008:        _MSC_VER=1500
Visual Studio 2010:        _MSC_VER=1600

So if you had checks in your code to specialize things for specific MS
compiler versions, you already had to know this "internal" version
number anyway. :)

That said, it should be easy enough to accept multiple forms on the
clang command line, as long as they are not ambiguous, e.g:

-fmsc-ver=1200    -fmsc-ver=vs6
-fmsc-ver=1300    -fmsc-ver=vs7    -fmsc-ver=vs2002
-fmsc-ver=1310    -fmsc-ver=vs71   -fmsc-ver=vs2003
-fmsc-ver=1400    -fmsc-ver=vs8    -fmsc-ver=vs2005
-fmsc-ver=1500    -fmsc-ver=vs9    -fmsc-ver=vs2008
-fmsc-ver=1600    -fmsc-ver=vs10   -fmsc-ver=vs2010
