Continuous integration on Windows?

Hi hackers,

I don't use Windows myself, but I'd rather avoid submitting patches
that fail to build, build with horrible warnings or blow up on that
fine operating system. I think it would be neat to be able to have
experimental branches of PostgreSQL built and tested on Windows
automatically just by pushing them to a watched public git repo. Just
like Travis CI and several others do for the major GNU/Linux distros,
it seems there is at least one Windows-based CI company that
generously offers free testing to open source projects:
https://www.appveyor.com (hat tip to Ilmari for the pointer). I
wonder... has anyone here with Microsoft know-how ever tried to
produce an appveyor.yml file that would do a MSVC build and
check-world?
