It most definitely is a new platform in a *lot* more ways than a new
version of gcc. It's the whole PlatformSDK. Why else did it require
patches to the code?
And it is a new feature *to the msvc build system*.

Well, it's perfectly possible to have more tha none version of MSVC on
the machine.
And we're not going to be changing the version that's actually used
for the official binary builds, so all you'll accomplish then is to
have the buildfarm test something different form what we're shipping.
