Subject: (UID_T_MAX): Use `(unsigned long)1' rather than
X-Git-Tag: FILEUTILS-3_12s~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5885cbf0d2d33802bed40c251addc92299eccc0c;p=platform%2Fupstream%2Fcoreutils.git

(UID_T_MAX): Use `(unsigned long)1' rather than
`(uid_t)1' to avoid problems on systems where uid_t is signed.
(GID_T_MAX): Likewise for gid_t.
