It'd certainly be possible for a buildbot to run libcxx's tests against VC 2015 Update 2 (or newer; I'll be checking in fixes for overloaded-comma that libcxx found). I don't know how to set up such infrastructure (it took me a while just to figure out how our internal Perl scripts were running libcxx's tests, and I'm still mystified as to how they're accidentally deleting a dozen algorithm tests when they run). But I'll be happy to contribute the additional chunks I've written (e.g. the force-included header that's defining various macros; although test_macros.h may be the proper place for that stuff to live in the future).
