bdist_wininst only works on Windows: see bpo-10945 and commit 72cd653c4ed7a4f8f8fb06ac364b08a97085a2b5. So $PREFIX/lib/python3.9/distutils/command/wininst-*.exe are useless on Linux (for example).

Attached PR modify "make install" to not longer install wininst-*.exe files.

I propose to only modify Python 3.9. Even if bdist_wininst only works on Windows on Python 3.*, I don't feel the need to modify other branches.

I also started a "Deprecate bdist_wininst" discussion on the Packaging list:
https://discuss.python.org/t/deprecate-bdist-wininst/1929

Currently, I get these .exe files:

$ find /opt/py39dbg/ -name "*.exe"
/opt/py39dbg/lib/python3.9/site-packages/setuptools/gui.exe
/opt/py39dbg/lib/python3.9/site-packages/setuptools/gui-64.exe
/opt/py39dbg/lib/python3.9/site-packages/setuptools/gui-32.exe
/opt/py39dbg/lib/python3.9/site-packages/setuptools/cli.exe

/opt/py39dbg/lib/python3.9/distutils/command/wininst-9.0-amd64.exe
/opt/py39dbg/lib/python3.9/distutils/command/wininst-9.0.exe

site-packages/setuptools/ and site-packages/pip/ are out of the scope of this issue.


With my PR:

/opt/py39dbg/lib/python3.9/distutils/command/wininst-*.exe files are gone.

wininst-*.exe files are created from PC/bdist_wininst/ program.

October 2018, there was a discussion about the license of these files:
https://mail.python.org/pipermail/python-dev/2018-October/155507.html

The Fedora package of Python 3.7 already explicitly removes these .exe files:
