I think its _MSC_VER instead of _MSC_VER_ actually.  I've started to  
chip away at MSW and NT, many externals and some parts of Pd are  
already using _MSC_VER and _WIN32 since I was porting things to MinGW.

To anyone who is listening!  ;) Don't use NT, MSW, MACOSX, UNIX!  There  
are automatic versions of these:

NT == _WIN32
MSW == _WIN32
MSVC-specific things = _MSC_VER
MACOSX == __APPLE__

and __linux__ or __gnu_linux__ are also good.
