From 06ca3797ac89c7c16a80ae8276bd23ef5b6f6a6f Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Tue, 15 Nov 2011 08:20:59 -0800 Subject: doc: update for ISO/IEC 80000-13 * doc/coreutils.texi (Block size): IEC 60027-2 has been superseded by ISO/IEC 80000-13, so prefer the newer standard but also mention the old.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 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. --- doc/coreutils.texi | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) (limited to 'doc/coreutils.texi') diff --git a/doc/coreutils.texi b/doc/coreutils.texi index 453144046..fa82a3107 100644 --- a/doc/coreutils.texi +++ b/doc/coreutils.texi @@ -901,10 +901,10 @@ A block size specification can be a positive integer specifying the number of bytes per block, or it can be @code{human-readable} or @code{si} to select a human-readable format.
