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.

What about scripts/recordmcount.c and scripts/sortextable.c which contains calls to setjmp() and longjmp() ?
And arch/um/ ?

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