1. There is use of `WIN32` instead of `_WIN32`.
2. There are comments referencing `Win32` which we need to rename to `Windows` 
to avoid confusion.
3. There is `class os::win32` in `os_windows.hpp` which is batter to rename to 
avoid confusion. Could be done in separate RFE.
4. "Note that, oddly enough, _WIN32 is still defined on 64-bit Windows". If it 
is really true, I would still suggest to use our variable `_WINDOWS` for that.
