C++11 (-std=c++11) does, but -std=c++0x probably doesn't.
That occurred to me too, so I tried -std=c++11 and got the same warnings spew.
Definitely a clang bug then. It should not enable C99 warnings by default in C++11 mode. The fix is to disable the warning in the Jamfile. I thought that the clang toolset already did that as we've discussed this issue with Edward Diener in the past, but I can't find -Wno-c99-extensions anywhere.
Is someone working on a fix? I'd be willing to take a patch that suppresses the warning from the Jamfile(s). That's obviously unsatisfactory since it doesn't help people who build in other ways. \e
