I agree that we should document the process.  Maybe also include
freebsd-numerics@ on these discussions, as that is why it was created.

But I'm really glad these changes were committed.  I have found the
people tend to drag their feet a lot on numerics issues.

Has anyone done an analysis of the OpenBSD powl functions from an
accuracy point of view?  That is, to test how many ULP of error these
functions have?  If not, I could give it a go, although not for several
months because life is very busy.
