It is not a straightforward backport.
atomic has changed a lot in gcc-4.7. is_lock_free() body is entirely
different between gcc-4.6 and r183875. In gcc-4.6, is_lock_free()
simply returns false or true. Notice that gcc-4.6 defines two
namesapce __atomic0, __atomic2 in separate files (atomic_0.h,
atomic_2.h), which disappear in gcc-4.7.
Even though, the idea behind the bug is the same. The new unit tests
will fail without this patch.

is_look_free() in r183875 necessary? If not why?
