It gives ... 4.10-STABLE FreeBSD 4.10-STABLE #0: Sun Jun 20 23:30:46
CEST 2004...

There is no difference in output for root and ordinary users.  Maybe the
simplest is to just do another make world cycle and see if that helps.
I have checked and the w program on the other machines are exactly the
same.  I even copied one over and ran that, but same problem.  An md5
message digest gives: 

$ md5 /usr/bin/w
MD5 (/usr/bin/w) = 4896e7d129e3d5c4eb26000ab9be68aa
