Bug report

Bug description:

Includes/internal/pycore_code.h uses static_assert() but does not inlcude pymacro.h, should it?

AFAIU pymacro.h makes sure that static_assert() is correctly defined for all supported compilers and platforms. Not including it in Includes/internal/pycore_code.h implicitly relies on pymacro.h being included before or via transitive includes.

I've found this while investigating a Cython extension module build failure. Cython includes the private header and thus requires static_macro() to be defined.

CPython versions tested on:

3.13, CPython main branch
