If you rename the .i file as a .cpp you can then add it to your project 
and right-click-Compile it individually.  If it still shows the original 
line numbers then generate the .i file again but turn on the "Preprocess 
Suppress Line Numbers" setting as well.

Well, it doesn't look like there's anything weird going on in there. 
Though if you do the above to locate exactly which line it's objecting 
to, it might help.

Since this is C++11 code, let's go back to basics for a moment.  Exactly 
*which* version of Visual Studio are you using?  (Both the main version 
and which Update you've installed.  You can check that in the About window.)
