I’ve made more edits than the bug report suggested to make sure the
generated setup script is compatible with many Python versions; a
comment in the source explains that in detail.

The cfg_to_args function uses old 2.x idioms like codecs.open and
RawConfigParser.readfp because I want the setup.py generated by packaging and
distutils2 to be the same.  Most users won’t see the deprecation warning and I
ignore it in the test suite.

Thanks to David Barnett for the report and original patch.

- Use a skip instead of hiding a method with an underscore
- Address pyflakes warnings

I need this for some tests, and it makes code clearer.  This commit also
changes some assertEqual calls to use (actual, expected) order and fix
some pyflakes warnings.

The code is still ugly, but at least it works better now.  Patches to
make it easier to read are welcome, as well as support in #12915.

Cool! Decoding b'\x81\x00abc' from cp932 with replace error handler is now
giving the same result on all Windows versions.

error handlers, instead of only replace to encode and ignore to decode.

sysconfig faster and reduces Python startup time by 20%.

used on Windows.
