Oh, I didn't know. That's probably why I got the bugs in turn.c. Now 
that I think about it, there are probably bugs that you can see in the 
other files... Oh, I see you just sent an email that proves my 
hypothesis, heh.

Not really. Not in over a year, anyway. In fact the only reason I 
undertook this warning-fixing project was to hone my newly-found coding 
skills.

So in summary:

-Those returns were supposed to be there and it was something else the 
compiler was whining about
-Cast to int to fix the array warnings
-Edit the makefile for Ewan. :P
