Hi Akim,

I've turned off -Wcast-qual warning for coreutils, grep, diffutils, etc.
For us, that seems to be the best route, since we try hard not to
add new casts (so there's little risk of introducing new violations),
and since the few code sites that provoke warnings have already been
carefully examined.
