Welcome to Clozure Common Lisp Version 1.4-dev-r13018M-trunk   
(DarwinX8664)!
? (defun foo (x)
     (* x 3))
FOO
?

i.e., I get no warning. All the warnings you've shown us so far are  
because you're invoking unspecified behavior by setfing an undeclared  
variable. Most implementations will obligingly do the equivalent of  
defvar if you setf an undeclared variable, but the standard does not  
require them to.

Just get in the habit of doing:

? (defparameter a 3)
A

and you'll get no warnings:

? (the number a)
3
?

Ralph
