Ticket details:
Clang analyze gives a div by zero warning about sdl2-client popup_goto_airlift_dialog() line "if (!((i + 1) % col)) {"
Seems to me that it could only happen when number of players allied to the client player (including oneself) is zero. That could happen if the function would ever be called by a global observer, but I don't think it ever happens. So no real bug there - just silencing the warning (and becoming more robust for any future changes where global observer could call the function)
