Msvc 2013 seems to get it right, and i can gladly argue that we
shouldn't support any older Msvc's just for the sake of it.
How many do actually build subsurface for windows? You, Dirk and maybe 1
2 other dev's, but thats probably it. Dirk uses mingw, and you would
know to use msvc 2013, so it doesn't feel like a show stopper for me =)
But, if we as always, if we know that things break with older msvc's we
should document it.
