Could anybody enlighten me, please?

1) What is current status of POSIX semaphores? Are they at the production
quality? Are they better implemented than SYSV ones?
2) What is kernel option to turn them on? Why I don't find it in NOTES or

The reason why I ever ask is that some ports try to sense POSIX semaphores
at configure stage (looking for sem_init()) and then compiled program
fails with "Unknown system call" diagnostic.
