--- Comment #12 from Harald van Dijk <harald at gigawatt dot nl> --- (In reply to Harald van Dijk from comment #11) > The programs in my comment here are accepted by G++ 4.5.4 (with -std=c++0x), > and rejected by 4.6.4 and later. But as G++ 4.5 recognises but simply ignores the constexpr keyword, it's not really a regression. 4.6 is the first that actually implements constexpr functions, and it was broken in that version already.
