I reference the symbol environ(7) but the linker is choking on it:

What doesn't libc export that symbol? What am I doing wrong?
Are you building a shared library? If so, that symbol gets filled in
at process startup time, so it is only defined in executables. You
need to do something like:
#include <crt_externs.h>
#define environ (*_NSGetEnviron())
