Subject: (touch): Extend the change of 2001-09-15 to work on
X-Git-Tag: FILEUTILS-4_1_3~9
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7afc9d18292231719e569fbc89582e3d53d2293a;p=thirdparty%2Fcoreutils.git

(touch): Extend the change of 2001-09-15 to work on
systems for which errno is set to EPERM in that case.  Thus, e.g.,
`touch /' by non-root gives a better diagnostic on systems like SunOS4.
