Got rid of the setuid, thanks. I'm not sure why the 21.2 emacs is so
small or the suid was there, so I checked on another Tiger machine. I
can't be entirely sure emacs wasn't there from 10.3 (Panther), can't
remember. If it's a virus, it still worked as emacs :)

This is mine (now)

-r-xr-xr-x 1 root wheel 30008 Aug 19 2006 emacs
-rwxr-xr-x 1 root wheel 21227988 Jul 2 11:00 emacs-i386

-rwxr-xr-x 1 root wheel 50944 Aug 19 2006 emacsclient

This is the other OSX Tiger 10.4

-rwxr-xr-x 1 root wheel 22640 Mar 26 2005 /usr/bin/emacsclient

compared to my /usr/local/bin emacs 22.2
