pip install failure on homebrew Python 3.11 with clang error

Problem description

Tried to install gensim on macOS with Python 3.11 from homebrew, but it failed due to compilation error.

pip3.11 install --upgrade gensim runs into

Python 3.10 and pip3.10 install gensim: work.

I see other projects have hit similar with Python 3.11. It might be an issue requiring a cython upgrade before our .c files are compiled (if I'm reading aio-libs/aiohttp#6600 right) – perhaps to cython-0.29.25 or higher? Or, perhaps it's fixable with some extra CFLAGS under Python 3.11, if comment at termux/termux-packages#13327 (comment) applies – though conversation there also implies that maybe this header file shouldn't be referenced at all by external code?

Hello, any updates on this issue? Thanks!

It should be fixed by #3430. Waiting for a review/merge.
