Making it possible to run scons on vista using VS2008 without having to install an additional MS SDK. VS2008 does come with SDK version 6.0, it's just that the registry entries for it are slightly different than in XP. This change takes care of Vista but I'm not sure what the registry looks like in Windows XP when you install VS 2008.
