Yes, to the extent that the syntax (locate-library "cc-mode.el")
*used* to work up to the point that the *.el's were compressed. Here
are two cases I can think of:

1. My fingers sometimes add the .el extension without my asking. I
   often load .el's, as they are easier to debug. That's what prompted
   this original bug-report.

2. If someone has legacy ~/.emacs code like the following
   example, but without the optional 2nd arg of nil, a move from
   Emacs-21.3 -> Emacs-22 would unexpected not load/execute their code
   fragment:

   (when (locate-library "specman-mode" nil)
       (progn
         (autoload 'specman-mode "specman-mode" "Specman code editing mode" t)
         (add-to-list 'auto-mode-alist '("\\.e\\'"      . specman-mode))
         (add-to-list 'auto-mode-alist '("\\.e3\\'"     . specman-mode))
         (add-to-list 'auto-mode-alist '("\\.load\\'"   . specman-mode))
         (add-to-list 'auto-mode-alist '("\\.ecom\\'"   . specman-mode))
         (add-to-list 'auto-mode-alist '("\\.etst\\'"   . specman-mode))
           ))

Thanks,
