I can shed some light on these warnings.
sem_init() and sem_destroy() are POSIX-defined interfaces for UNNAMED
semaphores.
There are also POSX interfaces, sem_{open,close,unlink}(), that operate on
NAMED semaphores.
See for more info:
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/semaphore.h.html
According to the following link Mac OSX only implements the NAMED
semaphores and I would guess they are now deprecating the ones that just
return -1 and set errno=ENOSYS:
