Clang now follows GCC's behavior with regard to that specific example, which makes sense, as Clang more or less explicitly aims to correctly compile the GNU dialect of C. I think it's reasonable (and even important) for Linus to emphasize that the kernel is coded in GNU C, not strictly standards-compliant C.

> Clang more or less explicitly aims to correctly compile the GNU dialect of C That was super important as the compiler was first starting out, because (A) Apple's existing code was built with GCC, so it relied on GCC flags & extensions, and (B) for it to be a viable open source compiler, it needed to build large existing codebases which were already using GCC. However, that doesn't mean that Clang will always continue to support every thing GCC does. Whether they by design or by accident, incompatibilities will arise. Of course, projects as tightly coupled to GCC as the Linux kernel might not care.
