--- Comment #18 from Jakub Jelinek <jakub at gcc dot gnu.org> --- i386 is an overloaded term, sometimes it means just i386 CPUs and not i486 and later, at other times it means the all CPUs capable of running i386 32-bit code, sometimes it means ia32. I don't think it would be a good idea to change the defaults, that would do more harm than good and all users can pick their own defaults if they don't like the defaults.
