Yes it does.

The fix makes sure build_ext.get_ext_filename still works as it is supposed
(just returning the extension of a filename depending on the
environment) under all versions,

*and* continues to do extra work for the Setuptools internal needs when
it is called by Setuptools itself on various places.

It's two lines in Setuptools.

But beware that a new Setuptools release might take a few months and
maybe will never happen.
That is why a suggested solution was to install Distribute, because it
addresses among other
bug fixes, this one.
