   Apple simply doesn't support __thread.

We could circumvent the top-level makefile entirely, but that would lock us into a permanent battle with doing the same with every metis release. Or I could just patch the top-level makefile to take a "cflags='-blah'" argument and hope that George accepts the patch. I'm leaning towards the patch. I've implemented both but will see how I feel about it tomorrow before I push any changes.

  I think you should "patch the top-level  makefile to take a "cflags='-blah'" argument and hope that George accepts the patch."
