commit f89ce35d83c705cfb9ae0564d1999f39c4e8fa83
Author: Matt Joyce <matthew.joyce@embedded-brains.de>
Date: Thu Feb 3 10:18:53 2022 +0100
Add _REENT_CLEANUP(ptr)
Add a _REENT_CLEANUP() macro to encapsulate access to the
__cleanup member of struct reent. This will help to replace the
struct member with a thread-local storage object in a follow up
patch.
