[Bf-committers] MSVC compiler optimize flags

[Ton Roosendaal]

Hi,

I think Brecht has found the offending unused variables. So it's no  
MSVC optimize bug after all. :)

Related to this; I also heard the Windows version renders slightly  
brighter than Linux/OSX versions. Would anyone with both OSes available  
be able to test it? Maybe that's really related to optimize flags?
