I tried it on a 3B2/400 running S5R3.1 and the access time *is* updated when
you run a program; it should be, since I consider running a program to count as
an "access".  Maybe the releases you were running were broken, or maybe older
versions of UNIX didn't do this but somebody thought better of it later?
