Actually, I build custom kernels, and I must have deleted the option
P1003_1B_SEMAPHORES by accident.

FreeBSD 7.3-RELEASE Release Notes says that "FreeBSD now supports POSIX
semaphores (P1003_1B_SEMAPHORES kernel option) by default" - I should
assume then that the option P1003_1B_SEMAPHORES has been included by
default in all 8.x versions, correct?
