The build failure is due to the fact that on 32-bit, uintptr_t and unsigned might be the same type.  Well, they're always compatible in type in the sense that unsigned and uintptr_t will both be 32-bit but there's an open question as to whether uintptr_t is "unsigned int" or "unsigned long".

The most robust solution is to rename the two weakCompareAndSwaps to:

weakCompareAndSwapUnsigned(...)

and:

weakCompareAndSwapPointer(...)

Then there won't be problems.
