The MACOSX platform is broken because no matter what you do it seems to
include files from [[/usr/include/sys]] ahead of [[/usr/include]]. On linux
systems these files include themselves which causes an infinite regression
of includes that fails. GCC gracefully steps over that problem but the
build fails anyway. On MACOSX the [[/usr/include/sys]] versions 
of files are badly broken with respect to the [[/usr/include]] versions.
