compile warnings on Ubuntu

[Stefan Beller]

First time compiling Caesaria (master branch) :) using gcc (Ubuntu 5.3.1-14ubuntu2) 5.3.1 20160413 (On Ubuntu 16.04) and I get these warnings during compile as found at http://pastebin.com/raw/pfR8PUBL

I'm not sure on your stance on warnings (I tend to make them go away usually, so I report it here)
