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

|
cannot trust that the architecture that Python is built for is the 'native'

|
|
one because you can run 32-bit apps on 64-bit Windows using WOW64 and

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

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.

MSVC toolchain architecture as our 'native' architecture.

2. If not, check environment variables that are set by Windows and WOW64 to
|
|

find out the architecture that Windows is built for, and use that as our

'native' architecture.
