I'd have to convert it to cmake, and the code fragment I posted in the the 
original message suggests they are already (attempting to) deal with Mac OS 
X so I'll just wrap the call in #ifdef _POSIX_THREAD_PROCESS_SHARED.  I'm 
pretty sure the execution never gets near this bit of code in the non 
shared case.
