--- Comment #118 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-09-28 12:21:31 UTC --- (In reply to comment #117) > Any chance of this being backported to older branches? Seems quite useful for > the future. I don't think this (very good, but quite major) change qualifies for stable release branches. If someone is (perhaps foolishly) relying on __cplusplus==1 in 4.5.3 we should not break their code if they upgrade to 4.5.4, they should reasonably expect only bug fixes in that upgrade
