NB that you probably don't need to exclude these (I think _win.{h,cc} are
auto-excluded on other platforms).

The stuff below seems to indicate that you are right to add this, but I wonder
if (a) I'm wrong or (b) someone else also unnecessarily added these.

Since we're make this non-specific to window, this is removed regardless.
