gh-121617: Include <string.h> for Py_CLEAR() macro by vstinner · Pull Request #144666 · python/cpython

bedevere-app

If the _Py_TYPEOF macro is not available, include <string.h> to get
memcpy() for the Py_CLEAR() macro. The limited C API version 3.11 and
newer doesn't include <string.h> anymore.

Add a Py_CLEAR() test in test_cext.

Modify also _Py_TYPEOF to use C23 typeof() if available.
