Since bpo-36302 was implemented, extension sources are now sorted for reproducibility. This is causing an issue in pywin32 as the *.mc files must be processed first to ensure the *.h files are generated before trying to compile the actual sources. I'm not very familiar with Windows but there are more details in: mhammond/pywin32#1590

As suggested in the issue, the solution is probably to modify msvccompiler.py to process the .rc and .mc files before any C/C++ sources.

Distutils is now deprecated (see PEP-632) and all tagged issues are being closed. From now until removal, only release blocking issues will be considered for distutils.

If this issue does not relate to distutils, please remove the component and reopen it. If you believe it still requires a fix, most likely the issue should be re-reported at https://github.com/pypa/setuptools
