From a quick look at the bug, the llvm/clang devs are quoting the C11 spec, yet we're not building with -std=c11 so I'm not sure that applies.

Can you give them a bit of TLS and send them to the list, please ? This also stands for the other patches in FreeBSD's repo :-) Thanks Emil _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
