I dunno. The early versions of UNIX had a back door in the login program put in by the designer. The compiler also watched for the login source code to be recompiled and added the back door. The compiler also watched for the compiler source code to be recompiled and inserted the login code modification code _and the compiler modification code. You can never be to careful.
I've let a lot of stupid comments go by, but I have to respond to this one. It is true that Dennis Ritchie (I believe, if not him, one of the other original UNIX authors) proposed such a login/compiler virus. But it wasn't in any early version of UNIX. Marc
