Commit aea447141c7e ("powerpc: Disable -Wbuiltin-requires-header when setjmp is used") disabled -Wbuiltin-requires-header because of a warning about the setjmp and longjmp declarations. r367387 in clang added another diagnostic around this, complaining that there is no jmp_buf declaration.[...]quoted

Hi Christophe, It looks like all of those will be using the system's setjmp header, which won't cause these warnings. Cheers, Nathan
