(GetVersion() & 0x80000000)==0) construct is very inefficient. It forces
compiler generate both a bit mask test and a comparison operation. While
many modern processors have very effective bit test instructions, and
we have to tell to the compiler that we want only a bit test.

Simple !(GetVersion() & 0x80000000) is much better IMO.
