Subject: [PATCH] python: enum: fix build for Python 3.11

Python 3.9 introduced Py_SET_SIZE function to set size instead of
|
|
relying on Py_SIZE() as a macro [3.9].
|
|
|
|
Python 3.10 started to encourage to use Py_SET_SIZE instead of
|
|
assigning into return value of Py_SIZE [3.10].
|
|
|
|
Python 3.11 flips the switch, turn Py_SIZE into a function [3.11],
|
|
thus Py_SIZE(obj) will be a rvalue. We need to use Py_SET_SIZE
|
|
to set size now.
