Python mingw and cygwin compiler classes tests for outdated features. Also python code set some flags like zero optimization level and etc. that prevent users to build optimized python or even worse build to fail.

This issue is part of split of bpo-3871 with clean-up and enhancements:

• archive contain set of 10 patches - remove of outdated (15 years old !!!!) features one by one.
• enhance unix compiler customization with mingw and cygwin compilers

[rpetrov]

Proposed customization allow users to build extension module for windows with GNU compiler in all environments:

• native with installed official build of python for windows
• native either MSYS or CYGWIN enviroment and python build with GCC
• cross-build in cygwin using official build of python for windows
• cross-build in cygwin or linux with use of preset configuration from distribution
• cross-build in linux and cross build python with GCC

In addition patch allow user to build (native or cross) core modules with recent gnu compilers.

Ping? Roumen has been updaing the patch for one year and no reaction. Is there something which can be done?

[bitdancer]

Find someone from the packaging sig willing to review it, maybe? As in, get on that mailing list and ask.

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
