Before we get old waiting for the windows buildbots, here how test_format
fails now (on XP SP2 x86, trunk rev 65072:
c:\svn\trunk\PCbuild>.\\python_d -E -tt ../lib/test/regrtest.py test_format
test_format
test test_format produced unexpected output:
**********************************************************************
'%F' % (1.0,) == '' != '1.000000'
u'%F' % (1.0,) == u'' != '1.000000'
'%f' % (nan,) == '-1.#IND00' != 'nan'
u'%f' % (nan,) == u'-1.#IND00' != 'nan'
'%F' % (nan,) == '' != 'NAN'
u'%F' % (nan,) == u'' != 'NAN'
'%f' % (inf,) == '1.#INF' != 'inf'
u'%f' % (inf,) == u'1.#INF' != 'inf'
'%F' % (inf,) == '1.#INF' != 'INF'
u'%F' % (inf,) == u'1.#INF' != 'INF'

Windows vsnprintf does not support '%F' at all, and '%f' does not
behave as expected with nan and inf.
