3.4 on Windows ImportError: cannot import name 'IntEnum'

I first saw this when tring to run the command "py -3.4 -m ensurepip" 
which gave me this lot.

Traceback (most recent call last):

ImportError: cannot import name 'IntEnum'

Before I raise an issue on the bug tracker can another Windows user or 
two please confirm that this is a genuine problem and not my 
installation being corrupt or whatever.
