I think it's very hard to be LP64/LLP64-clean without actual testing on

I'm sure patches would be accepted to clean things up. We imported a
private version of the xen headers into the winpv tree hg so maybe we
should just go ahead and modify that, and then we can pull out a diff to
submit against xen-unstable when we know all the issues are cleaned up?

Most of the 700+ warnings on x64 Windows winpv build is probably because
of this :)
