title: Including <Windows.h> causes (unknown attribute"no_init_all") error
body: <p>Title says it all, started a new project in VS2017, included <code>&lt;iostream&gt;</code>, then when I went to include <code>&lt;Windows.h&gt;</code> (This is my first attempt at working with this header by the way), I got the error saying: <code>unknown attribute&quot;no_init_all&quot;</code>
  Any idea what might be causing this?</p>
