I suspect the following might be related; now `defclass' is opaque to
the byte-compiler. Compiling this:

(require 'eieio)

(defclass foo-class ()
  (())
  "blah.")

(defun foo-func ()
 (if foo-class
  (foo-class 'blah)))

warns:
  
  In foo-func:
  foo.el:8:7:Warning: reference to free variable `foo-class'
  
  In end of data:
  foo.el:9:1:Warning: the function `foo-class' is not known to be defined.

which is a bit annoying. It didn't use to do this. A total guess, maybe
the removal of `eval-and-compile' from defclass?
