Subject: (change_file_owner): Save errno from a possibly failed chown,
X-Git-Tag: TEXTUTILS-2_0g~108
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d86f9d40a52e37e060427dfbcf35b85185ecc066;p=platform%2Fupstream%2Fcoreutils.git

(change_file_owner): Save errno from a possibly failed chown,
and use that later.  Otherwise, errno itself could be clobbered before used.
