Comment (by Volker Schöch <vschoech@…>):

 Thank you for looking into this. I have no issue with the code as it is.
 However, I do have an issue with the warning being triggered. If you know
 that the warning is triggered even though the code is fine, why not
 locally suppress the warning with `#pragma warning(disable:4189)`?

 Compiling with /W3 is not an option for me; I will continue to suppress
 this warning specifically for boost::geometry. That's not a practical
 problem, I just think suppressing it locally in your code, with an
 appropriate comment, would be a better solution.
