--- Comment #3 from Daniel Krügler <daniel.kruegler at googlemail dot com> --- (In reply to Jonathan Wakely from comment #2) > It does for G++, it's been accepted as an extension in C++03 mode for years. What I actually meant to say with my comment is that for a proper bug report the category should be C++11, because the argumentation of the bug report was based on standard wording and not based on a gcc extension statement. Therefore my own validation (e.g. when referring to gcc 4.9) did all happen with using std=c++11.
