* doc/coreutils.texi (Block size): IEC 60027-2 has been superseded by ISO/IEC 80000-13, so prefer the newer standard but also mention the old. The new standard specifies Zi and Yi, so they are no longer GNU extensions. Fix stale URL to BIPM. 2011-11-14 Paul Eggert <eggert@cs.ucla.edu> id: handle (uid_t) -1 more portably * src/id.c (GETID_MAY_FAIL): Remove. (main): Check for negative return values, not for -1. The old code was incorrect if uid_t was narrower than int, regardless of whether we were on a GNU or a POSIX platform. The new code is simpler and doesn't need GETID_MAY_FAIL. (print_full_info): Remove unnecessary cast to -1.
