From e3b88685f93b51ca2752fd47ef38e5a75de1f395 Mon Sep 17 00:00:00 2001
From: Eli Zaretskii <eliz@gnu.org>
Date: Sat, 5 Apr 2008 14:32:28 +0000
Subject: [PATCH] (sys_chown, stat, fstat): Use S_* constants instead of _S_*
 ones, since we now use our own sys/stat.h. (stat, fstat): Don't mangle the
 inode number.
