New Revision: 46263

Modified:
   pypy/branch/pypy-more-rtti-inprogress/rpython/module/ll_os_stat.py
   pypy/branch/pypy-more-rtti-inprogress/translator/c/test/test_extfunc.py
Log:
os.stat() returns bogus times on Windows.
Skip the tests for now.  This check-in contains the start
of the "correct" implementation and the reason why I stopped
working on it for now.
