Old FreeBSD's libc has a bug relate to utf-8 locale and Python have
patch for it: http://svn.python.org/view/python/trunk/Include/pyport.h?
view=diff&pathrev=43219&r1=36792&r2=36793

This bug appears in Mac OS X again. This test fails:
>>> s = '\xa0'
>>> assert s.strip() == s
>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
'en_US.UTF-8'
>>> assert s.strip() == s

So above patch should be enabled for Mac OS X.

I've attached a patch that fixes the issue and enables all test_locale tests on OSX 10.6.

(I will test if the tests can also be enabled on 10.5 when applying the patch).
