Well strncpy has performance issues on large buffers since it pads the
remainder with null bytes. I agree that it would be better to use
something else, though I don't like your util.c strlcpy solution
because that's calling strncpy as well and does some superflous
double-termination that seems to be unnecessary to me.

I applied both sic.c and util.c temporarily to sic/kris/, I need to
sort out what I'm going to re-use and what not. The state when you
patched sic.c seems to be quite old though... or your patch was quite
big ;)

Well apparently they push the line count to 296, but nevermind I agree
these ugly (void) casts have been removed in hg tip.
I was too quick when I applied the last patch provided by Martin.
