K&R -> ANSI cleanup status

[Sascha Wildner <saw@xxxxxxxxx>]

Just FYI:

I'll continue committing Alexey Slynko's remaining patches next weekend. 
I have also patches or my own for everything except sys/ which I'll also 
commit. So if anyone wants to help, I'd suggest contacting me by email 
so we can avoid duplicating work.

The plan is to set -Wold-style-definition when all definitions are 
changed to ANSI style. Next we can take care of missing prototypes.

P.S. I'm currently away from home during the week without commit access.
