+Subject: [PATCH] Fix enum_type_object type on Python 3.11
+
+The enum_type_object type inherits from PyLong_Type which is not tracked
+by the GC. Instances doesn't have to be tracked by the GC: remove the
+Py_TPFLAGS_HAVE_GC flag.
+
+The Python C API documentation says:
+
+    "To create a container type, the tp_flags field of the type object
+    must include the Py_TPFLAGS_HAVE_GC and provide an implementation of
+    the tp_traverse handler."
+
+https://docs.python.org/dev/c-api/gcsupport.html
+
+The new exception was introduced in Python 3.11 by:
+https://github.com/python/cpython/issues/88429

+open(), io.open(), codecs.open() and fileinput.FileInput no
+longer accept 'U' (“universal newline”) in the file mode.
+
+In Python 3, “universal newline” mode is used by default
+whenever a file is opened in text mode, and the 'U' flag
+has been deprecated since Python 3.3. The newline parameter
+to these functions controls how universal newlines work.
