[issue3748] [py3k] platform.architecture() prints vogus messege on windows

[Hirokazu Yamamoto]

Hirokazu Yamamoto <ocean-city at m2.ccsnet.ne.jp> added the comment:

This difference between trunk and py3k would go down to this.

import os
os.popen(r'file e:\python-dev\py3k\PC\VC6\python_d.exe 2> /dev/null')

trunk prints nothing, but py3k prints that message.

I don't know which is popen's correct behavior, we can supress this
message by using subprocess.Popen instead.
