Description
In pypa/distutils#259, I'm tracking down an emergent regression in the import logic that breaks the test suite on pytest 8.1 and 8.2.
It looks like it's successfully discovering distutils/cygwincompiler.py, but then when a relative import from there imports .version, it's getting $prefix/lib/distutils/version.py.
I haven't yet root caused it, and it may be related to https://github.com/pytest-dev/pytest/issues/12044 or other open issues.
I'll continue to investigate until I have a better reproducer.

Research direction
Start by reproducing the test-suite regression with pytest 8.1 and 8.2, then trace imports from distutils/cygwincompiler.py through the relative import of .version. Compare the discovered module with $prefix/lib/distutils/version.py and establish a smaller reproducer. Done means the intended distutils module is selected and the affected tests pass.
