[Distutils] distutils.util.get_platform() - Linux vs Windows

[samuel.ferencik at barclays.com]

Hi,

It seems distutils.util.get_platform() semantically differs on Windows and Linux.

Windows: the return value is derived from the architecture of the *interpreter*, hence for 32-bit Python running on 64-bit Windows get_platform() = 'win32' (32-bit).

Linux: the return value is derived from the architecture of the *OS*, hence for 32-bit Python running on 64-bit Linux get_platform() = 'linux-x86_64' (64-bit).

Is this intentional?

My context (where this hit me): I was trying to install the 32-bit version of the Perforce API (compiled module) on 64-bit Windows and on 64-bit Linux. My command-line was

  python3.3-32 setup.py install --root FOO --install-platlib=lib.$PLAT

(note the '-32' and the '$PLAT')

On Windows, this installed the 32-bit version of the API into "FOO\lib.win32". On Linux, this installed the 64-bit version of the API into "FOO/lib.linux-x86_64". I'm not sure which is more correct behavior but the asymmetry seems suspicious.
