pointer subtraction within the allocated object, where results might
overflow the ptrdiff_t type.
+* Add new POSIX-proposed pthread_cond_clockwait, pthread_mutex_clocklock,
+ pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and sem_clockwait
+ functions. These behave similarly to their "timed" equivalents, but also
+ accept a clockid_t parameter to determine which clock their timeout should
+ be measured against. All functions allow waiting against CLOCK_MONOTONIC
+ and CLOCK_REALTIME. The decision of which clock to be used is made at the
+ time of the wait (unlike with pthread_condattr_setclock, which requires
+ the clock choice at initialization time).

Deprecated and removed features, and other changes affecting compatibility:
