I see the problem, when building for windows without iphlpapi.h, mentioned function has no code within.
Will account for such case.

Problem here is that "+=" operator is a bashism, probably causing the previous error by not including iphlpapi properly.

Some questions I have:
Should I send another patch within this thread to address these comments, or should I create a V2 of the patch?
Also, if creating a V2, should the patch be sent within this thread, or should a new thread be opened?

Thank you for your time!
