short is 16 bits, long _can_ be 64 bit (for example it is 32 bit on
x86-linux) . In general, don't worry about all this stuff, don't use 
64 bit wide types and use Q_*16/32 where possible. The Qt typedefs 
are guaranteed to have the specified size, on all Qt supported
platforms (which is what matters here) .

Don't use the Q_(U)INT64 in Qt2 (as you can see it has been removed
in Qt3, because it doesn't deliver what the name promises, and it
isn't easy to get right (if at all)) .
