I haven't tested it so I can't be sure but I believe that if /Za is turned
on, you can't include any windows.h without many errors occurring. I believe
the windows.h header file has always failed when one is in C++ standard mode
( /Za ). There has been talk by MS of changing it to be C++ standard
compliant but I don't think that has been done in VC7.1.
