I presume you've read the long thread starting at 
<http://gcc.gnu.org/ml/gcc/2009-08/msg00199.html> regarding the issues 
involved in implementing the atomics (involving compiler and libc 
cooperation to provide stdatomic.h), and in particular ensuring that code 
built for one CPU remains safe on later CPU variants that may have more 
native atomic operations.
