Barring objections or additional feedback, I think I'm inclined to press forward with this one and commit it in the next week or two. I'm currently planning to keep the inline assembly, but I'm considering removing the configuration checks for __atomic_exchange_n() if the availability of __atomic_compare_exchange_n() seems like a reliable indicator of its presence.
