[Python-Dev] Is Py_WIN_WIDE_FILENAMES still alive?

I believe the macro should be removed, as Python currently assumes Unicode
APIs are available in a number of places.  This consistent with the versions
of Windows Python currently supports.  It is possible that patches would be
accepted which enable Python to be built without this functionality - in
which case the next-best behavior would probably be to convert Unicode to
MBCS encoded strings and call the *A versions of the API.  Looking at the
history for posixmodule.c etc will offer some clues as to how this could
best be done.
