On the Savannah coreutils project page: https://savannah.gnu.org/bugs/?func=additem&group=coreutils
The "Bugs" link points to: http://debbugs.gnu.org/coreutils/ But that location produces an HTTP 404 Not Found error. The working link location is: http://debbugs.gnu.org/coreutils I don't know if enhancing debbugs.gnu.org to accept that URL is a better solution than fixing the linking url. Bob
