[issue20129] 3.4 on windows 7 can't import IntEnum

[Mark Lawrence]

New submission from Mark Lawrence:

c:\Users\Mark\CrossCode>py -3.4 -c "from enum import IntEnum"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name 'IntEnum'

I had earlier tried to install the complete 3.4 setup on Windows 7 but, for the first time that I'd ever seen, the installation rolled back.  So I installed without pip and then ran this command "py -3.4 -m ensurepip" which gave me this:-

  File "C:\Python34\lib\socket.py", line 51, in <module>
    from enum import IntEnum
ImportError: cannot import name 'IntEnum' 

I suspect my installation is corrupt somehow but thought it safer to flag this just in case.
