I think what we want is basically the UNION ALL of all the different active
versions. If we just use the definitions from Win10, we will map
incorrectly on Win7. As long as they are not *conflicting*, we should just
add them all.

The UTC->GMT switch is mostly just annoying as it only hits the comments,
right? I think we just accept that change and do a once-over patch that
changes all those things.
