Any further comments?

A couple, I'm afraid ;)

Richard, you are very helpful with this work. Thank you.

I also changed the built-in function descriptions to match the style
used elsewhere.

Finally, I adjusted the patch so that it applies on top of the
built-in-table patch I sent yesterday in the [3/5] thread.

Are you sure you posted the built-in-table patch? I couldn't find it neither in gcc-patches@ archive nor in mailbox. The hunks below do not apply to current trunk, supposedly because of this.
