Verify that the sconsign script works when using a .sconsign file in

# Windows.  If we didn't do this, then running this script with
# suitable prileveges would create a .sconsign file in the directory
# where the Python executable lives.  This can happen out of the
# box on Mac OS X, with the result that the .sconsign statefulness
# can mess up other tests.
