You cannot interchange pointers to uint64_t and pointers to unsigned 
long long, you must select one or the other, pretend that long long is 
128 bits, and uint64_t is 64 bits, and conceptually, you won't go 
wrong.  That is the only thing you did wrong, and no fix that doesn't 
address this fundamental problem will _fix_ it.  No casting, no -w, no 
ignoring it.
