I think maybe I should not have put const there. It means the
pointer shouldn't be modified and I think there is code that
does that, or cast to some other pointer which is not const:ed
and then use things like ++ on the resulting type.

If you run into compile warnings you can just delete the const,
or I can send a follow-up patch.
