Should they be turned into compat symbols *because* they won't be
installed headers (and we don't want new user code linking against them)?
Or is there something else to it?
As for binary128 compatibility wrappers for them, I agree (I haven't
created these on my branch, so this should already be in sync with your
suggestions).

That would help a lot! :)
