I briefly considered whether we want to think about some kind of version check (e.g., warn if GCC-compatibility-version < 4.6), but going in that direction will drive us insane. So...
Your patch looks good, but could you submit it again as an attachment instead of inline? It doesn't cleanly apply for me this way (http://llvm.org/docs/DeveloperPolicy.html#patches)
