Yep, from python 2.4 on, os.environ changes only work within python and
no longer apply to low level c stuff on win32. Luckily, it's still
possible to force environment variables through the
kernel32.SetEnvironmentVariableW and msvcrt._putenv functions.

Put the attached locale module in a libi18n package and use like this:
#!/usr/bin/env python
from libi18n import locale
locale.fix_locale()
del locale
