Hi Jason,

currently we are not using any patch on SetupTools
Last I packaged is 59.5.0 for python 3.6 to 3.9

https://cygwin.com/packages/summary/python-setuptools-src.html

there are several patches on Python source that include the distutil port=
ion

I just updated the patches used on last binaries on :

http://cygwin.com/git/cygwin-packages/python39.git
http://cygwin.com/git/cygwin-packages/python39.git

they are almost identical

General information on our python packages are also on:

https://cygwin.com/packages/summary/python38-src.html
https://cygwin.com/packages/summary/python39-src.html
