Thanks for the feedback, Bruno, but I agree wrt -W.
At least in the coreutils, there are just too many places
where -W produces false-positive and hard/messy-to-remove warnings.
I've tried, periodically, to enable that option, but the cost in
readability/maintainability (e.g., due to added casts) has always been
prohibitively high.
