I'm not sure if Cython can generate code compatible with PEP 703, we are dependent on that generating the correct C code needed here to compile in this mode. I think cython/cython#6162 might be the overarching issue covering that but I could be wrong.

I had exactly the same errors about __pyx_vectorcallfunc building PyYAML's libyaml extension under 3.13t- defining CYTHON_VECTORCALL (which just aliases to the builtin vectorcallfunc) worked for me via CFLAGS='-DCYTHON_VECTORCALL' or extra_compile_args or whatever- dealer's choice.
