Fixes OSAtomic link errors when using 10.9 SDK

clang doesn't like the change made to the OSAtomicIncrement/Decrement64 function declarations in the 10.9 SDK.  They now have "inline __attribute__" which combined with the ternary statement (see code)  yields linking errors, so we have to expand it as a workaround. Possible compiler bug, filed as radar 15066446.
