Changing the compiler to GCC solves the problem for me (export CC=$(which gcc-11)), but then there are problems with __builtin_available which is exclusive to clang. So you can set CC back to clang after running configure by modifying the generated Makefile in build/macOS/Python-3.10.0-macOS. I'm not sure how to really fix it but I think it's a problem with Python, not only this project. https://bugs.python.org/issue44065

Yes, incompatible comes from apple clang with standard gcc. Thanks for the solution.
