That forward-fix was just a test change, doing a #include in our tests isn't 
something we can do, as it makes them fail with "file not found".  As far as 
your errors, it shouldn't be because of those, but could definitely be a 
problem wiht the originnal patch, hopefully @mahtohappy can get a chance to 
look at this.
