121 NOTE: Your system does not have /dev/fd mounted. If you want to
122 be able to use set-uid scripts you must ask your system administrator

163 NOTE: Your PATH points to GNU make, and your GNU make has the set-group-id
164 bit set. You must either rearrange your PATH to put /usr/ccs/bin before the
165 GNU utilities or you must ask your system administrator to disable the
166 set-group-id bit on GNU make.
