    Detecting the 'native' architecture of Windows is not a trivial task. We

    people sometimes install 32-bit Python on 64-bit Windows.

    We also can't rely on the architecture of the OS itself, since it's
    perfectly normal to compile and run 32-bit applications on Windows as if
    they were native applications. It's a terrible experience to require the
    user to supply a cross-info file to compile 32-bit applications on 64-bit
    Windows. Thankfully, the only way to compile things with Visual Studio on
    Windows is by entering the 'msvc toolchain' environment, which can be
    easily detected.

    In the end, the sanest method is as follows:
    1. Check environment variables that are set by Windows and WOW64 to find out
       if this is x86 (possibly in WOW64), if so use that as our 'native'
