test_urllib's test_geturl fails with following messege.

test_urllib
test test_urllib failed -- Traceback (most recent call last):
  File "/home/WhiteRabbit/python-dev/trunk/Lib/test/test_urllib.py",
line 84, in
 test_geturl
    self.assertEqual(self.returned_obj.geturl(), self.pathname)
AssertionError: 'file:///tmp/@test' != '/tmp/@test'

test_support.TESTFN is /tmp/@test on cygwin, and Lib/urllib.py(484,485)
specially cares about leading slash. 

            if file[:1] == '/':
                urlfile = 'file://' + file

If this is geturl()'s design, probably test should be changed like
attached patch.
