• Subject: [C++ PATCH] Two trivial tweaks to -Wc++0x-compat

Hello all,These are two completely trivial patches to tweak the behavior of -Wc+ +0x-compat. The first one turns off -Wc++0x-compat when the C++0x mode is enabled (e.g., via -std=c++0x). The second one makes -Werror=c ++0x-compat work.Tested i386-apple-darwin8.8.1, no regressions.Okay for mainline?

Cheers,
Doug
