--- Comment #16 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2011-10-23 21:43:27 UTC --- (In reply to comment #14) > Patch needs preliminary clean-ups in gcc/config, etc. It seems to me that enabling -Wc++0x-compat with -Wall is not a good idea anyway. I guess many people would not care about upgrading to C++0x for a while, and they will be pissed off when their builds break. Maybe you should do it for the release just before -std=c++0x is the default, if such thing is even planned, but not for 4.7. (I personally do not understand why this is an obligatory warning in C++0x, it seems something that many people will consider a nuisance, but that is beyond the point here).
