Alternatively, one could remove the {set-{UID,GID},sticky} bit with "chmod
0755" if one liked numbers better than letters. (This works under SunOS

[[ Yes but things changed under 4.0. Near as I can tell via
experimentation, "chmod" now treats directories as a special case. The
only way to turn off the setgid bit on a directory is via "chmod g-s ...".
I tried "chmod 0755" and it got the sticky bit but not the setgid bit,
although it works as expected for a plain file. --wnl ]]
