Works for me, and for other developers, and for assorted buildfarm

That is bizarre. Can you show the segment of config.log
that corresponds to this? The exact error message that
the compiler is reporting would be useful.
Also, I wonder if you are using Apple's gcc (yeah, that's
really clang), or a gcc from MacPorts or Brew or the like.
