As XP is our default version, I'd say stick with XP+ behavior. If apps 
depend on something else (due to running on a different Windows version 
as set in winecfg) we can always look into making it more version 
dependent. In general we should not be depending on the Windows version 
for our implementation, but you will find some places in the code where 
we are.
