Hello,

I compiled a program on windows XP with MinGW and the the Qt libs statically linked.
This works nice.

The executable runs as well on Vista and windows 7.
However, is there any difference in speed/performance when I compile it on Vista/windows 7?
Does, for example, QPainter gains performance when I compile it on windows 7?

In other words, is there any reason to compile/build different executables for windows XP, Vista and 7?
