You're right that's cleaner.

I'll fix that.

I missed the bracket indeed (mistakenly removed the mangle initially).
As for LABEL_MANGLE vs. MANGLE I can change it back. LABEL_MANGLE is
only different from MANGLE in case of ARCH_X86_64 && defined(PIC) (which
equals BROKEN_RELOCATIONS) hence it doesn't really matter, I don't know
which one is "more correct" but I'll change it back.
