| ``<Python.h>`` no longer includes the header files ``<stdlib.h>``, | |
| ``<stdio.h>``, ``<errno.h>`` and ``<string.h>`` when the ``Py_LIMITED_API`` | |
| macro is set to ``0x030b0000`` (Python 3.11) or higher. C extensions should | |
| explicitly include the header files after ``#include <Python.h>``. | |
| Patch by Victor Stinner. |
