My GCC seems to be GCC (don't remember why - I guess I installed it for something). I can also make it build using "--std=c99" (but that makes the undefined behavior mentioned in issue #2 show up, which is why I went with clang).

  gcc: warning: couldn't understand kern.osversion '14.3.0
  gcc (GCC) 4.8.2
