Maybe someone now can start to push the gcc patch upstream?

Although I don't have anything specific, this is a subtle area and I have had to fix bugs in this code before. I would like to see that this code actually works in the real world in code that uses the GCC atomic support (e.g., glib2.0). I'm still not sure we have correct types in our code (arm revamped some of the types used in their implementation).

We have some time before gcc-5.0 is released. As a new feature, it normally would
not be back ported without strong justification.
