A PEP on 2.7 seems questionable - if this would really need a PEP,
it would be right out (IMO). A PEP would ask for community input,
weighing possibly different design choices.

Instead, I think this needs explicit RM approval, such as any other
borderline bugfix patch. I'd personally support it, including any
distutils change (assuming the changes "look" backwards-compatible) -
but it still would be for Benjamin to rule about it.

Perhaps. However, Python 3.4 is likely being replaced before VS 2010
ends its life, and people will be more quick to forward-port to 3.5.

There used to be an MSDN article about it, but I think it was
incomplete. It mentioned (IIRC) a) locale, b) malloc, c) struct FILE.
Not sure whether it mentioned CRT file handles, and I'm fairly
sure that it didn't mention errno. I also don't think that timezone
issues were mentioned (although there used to be a separate article
about CRT timezones).

So if you can get somebody to compile a complete list, publishing it
as a KB article would certainly be appreciated beyond the Python
project.

You are not a Python committer yet, are you? If you are, go to
hg.python.org/cpython, and invoke the server-side clone. If you
are not - does your company agree if you would become one?

In any case, patches or a clone on bitbucket would work just
as well.
