Windows (and vs) version numbers are a pain in the ass though. Constantly need to check that the version you need to put in some config file actually corresponds to the version you really mean.
I haven't seen anyone do a good job of it, but it seems to me that if you wanted to try, the way to do it would be to make the marketing versions and compatibility versions so different that they can't be confused (like Windows 95 or better yet XP, not Windows 7) - and then make sure that your configuration files can accept marketing versions and silently transform them to compatibility versions.
