/* Due to removal of old Buffer Protocol in python-3.13 and the new Buffer Protocol only being added to the Stable ABI in python-3.11, this test can be run only if:
 *
 * 1. Py_LIMITED_API is not set
 *
 * or
 *
 * 2. Py_LIMITED_API is set
 * and
 * 2a. python >= 3.13 and Py_LIMITED_API >= 3.11
 * or
 * 2a. python < 3.13 and Py_LIMITED_API < 3.13 (actually any value for Py_LIMITED_API, but any Py_LIMITED_API greater than the version of python is treated as if it is set to the python version)
