Log:
2008-10-02  Farid Zaripov  <faridz@apache.org>

	* include/rw/_atomic-sync.h: New header file with definitions
	of inline functions for atomic operations using __sync_xxx()
	built-in functions set.
	* include/rw/_atomic.h: #include <rw/_atomic-sync.h> with
	gcc >= 4.1 on x86, x86_64, ia64 platforms and icc on ia64 platform.
