This recently broke for me on OS X (with clang 3.1) as well. Casting 'ptrOld' to (void*) works and this is also done for the other implementations (WIN32_INTERLOCKED and BSD_ATOMIC) as well. No ideal, both 'ptrOld' and 'ptrNew' are only read and could actually both be const but aren't for some reason.
