The fix for permission() that makes it compliant with POSIX.1-2001
apparently was lost.  Here is the patch I sent before.  (The relevant lines
from the standard text are cited in
http://www.ussg.iu.edu/hypermail/linux/kernel/0310.2/0286.html.  The fix
proposed in that posting did not handle directories without execute
permissions correctly.)


Make permission check conform to POSIX.1-2001

The access(2) function does not conform to POSIX.1-2001: For root
and a file with no permissions, access(file, MAY_READ|MAY_EXEC)
returns 0 (it should return -1).
