Nope. We should just not rely *in the library* on anything requiring pthread_mutex_timedlock if the macros is not defined > 0. Or, in case it's defined as == 0 we should check at run time. But the gthr-posih.h is ok as is.

For now, for darwin, I'm going to add _POSIX_TIMERS > 0 in the macros protecting the headers, but we need something more fine grained, around specific functions in the implementation requiring pthread_mutex_timedlock.
