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.
