The _xgetbv requires Visual Studio 2010 SP1 or greater, not VS 2012.

MSDN's documentation wasn't updated until 2012 though, so it's a bit confusing.

That being said, it should still compile in a non-SP1 VS 2010, but I
believe the original code does that because 160040219 is the
identifier for 2010 SP1
