I have run the 'test_install_lib' on cpython3.3(windows version), the 'test_install_error' failed.

The detail is:

FAIL: test_install_error (__main__.InstallLibTestCase)

Traceback (most recent call last):
  File "D:\add-develop-command\Lib\distutils\tests\test_install_lib.py", line 112, in test_install_error
    cmd.run()
AssertionError: DistutilsFileError not raised


The corresponding lines are:
