Re: [Bug-apl] *** Spam *** Error compiling on Mac OS X 10.13.6

According to stackoverflow, Darwin doesn't support unnamed semaphores, so sem_init is deprecated and always returns failure, and you should use named semaphores (sem_open) instead.

Hi Louis,

I vaguely remember that we had that problem on MacOS earlier, but I don't remember
anymore what the solution was. Any proposals?
