Notice the filesize. I bet this was a shell script that didn't
pass arguments to the real gsi (or may be this gsi was doing
something completely different). If this file is still around
Steve can `cat -v' it to see what's in it. cat -v just in
case it contains some binary data.

Notice the different modify date of each gsi. My guess is
/usr/bin/gsi was locally created and left over from something
earlier. [And there is an admin bug: -rwxrwxrwx implies root
is likely using a umask of 0! Root should use `umask 022']

The one in /usr/bin was a bash file which changed the directory to /usr/local/gambit/gsi and executed ./gsi

Maybe some of this came from Mint Linux' package manager.
