#34: get-dispatch-macro-character doesn't signal errors in compiled code

 This example is from the clisp mailing list

 {{{
 * (defun dispatch-macro-char-p (char rt)
   (handler-case (prog1 t
                   (get-dispatch-macro-character char #\x rt))
     (error () nil)))
 DISPATCH-MACRO-CHAR-P
 * (dispatch-macro-char-p #\$ (copy-readtable nil))
 NIL
 * (compile 'dispatch-macro-char-p)
 DISPATCH-MACRO-CHAR-P
 NIL
 NIL
 * (dispatch-macro-char-p #\$ (copy-readtable nil))
 T
 }}}

 I think this is because {{{get-dispatch-macro-character}}} is declared
 to be flushable.  I think that's wrong since
 {{{get-dispatch-macro-character}}} is supposed to signal errors.
