We don't currently use the frozen C++03 headers quite yet (AFAIK?), but once we do, I guess this would crop up whenever trying to run tests in C++03 mode on Windows. (We don't test all standards modes on all OSes currently though.) So I guess we would need to do this kind of maintainance on those otherwise supposedly frozen headers?

Yes, this is one place where we'd probably have to change the C++03 headers. They should be frozen as much as that's maintainable, so I don't think that goes against the idea.
