--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Yes this does not seem like a good idea.
Unlike the other places where we open code things; this one place will
basically go back to the open coded version for most hosts (as mentioned by
Jakub).
So this might actually be slower at compiling gcc (ever so slightly).
