 > See comment #3 for why this is invalid.  This is a system header, and if
 you're missing it, you either deleted it or never installed it.

 As for david.w.watson's machine above, Availability.h was always sitting
 in my /usr/include, but MacPorts (or the clang build process) couldn't
 find it. What environment variable(s) should it be using to look there? Is
 it possible that this particular release of clang is relying on an
 environment variable previous versions didn't look at?
