This was legal in CW8.3, but I get a warning in Xcode 2.1

UInt64          startTime, deltaTime;
AbsoluteTime    absDelta;

absDelta.hi = (deltaTime & 0xFFFFFFFF00000000) >> 32;

Can Xcode not handle a 64bit bitwise AND with bitshift?


Numeric constants are of type "int" by default.

Try  "0xFFFFFFFF00000000ULL" instead.

It is by caffeine alone I set my mind in motion.
It is by the beans of Java that thoughts acquire speed,
the hands acquire shaking, the shaking becomes a warning.
