You'd have to use C++0x and the -std=gnu++0x compile flag to get this
to work, and the lack of this is what I'm assuming is the cause of your
compilation fail.

How would you bridge parallel/compatability.h constructs to
C++0x cstdatomic?

I think this would be an interesting experiment, although I can
understand your reluctance to require C++0x flags for compilation.
