Don't use Win32 directly. Use a threading lib instead. The threading lib
itself of course needs to include windows.h and is therefore compiled
without /Za. But that does not mean that the client code cannot use /Za
because all it sees is (for example) thread.h and thread.lib. No windows.h
anywhere.
