You have already forked the semaphore code. You need to fork the
cancellation and thread code to fix the infamous MacOS decoder bug. Now you
are forking the clock code, and consequently you need to fork the condition
variable code too.
So only the mutex code is left common, or about 10% of the code. Now sorry
but by definition of "most of code" means more than 50% thereof.

No, I am referring to clock selection, not to monotonic clock.

It compiles because of that but it most certainly does not work.
