Subject: 25.1.50; REGRESSION: Emacs 24.3 breaks loading cl-macs to get macro
 `case'
Date: Fri, 1 Jan 2016 19:23:03 -0800 (PST)

This regression was introduced in Emacs 24.3.  Prior to that, code could
use (require 'cl-macs) to have macros such as `case' provided at
runtime.

(eval-when-compile (require 'cl)) still works, of course.  But neither
(eval-when-compile (require 'cl-macs)) nor (require 'cl-macs) defines
macro `case', starting with Emacs 24.3.

This gratuitously breaks any existing code that loads cl-macs expecting
to get the definition of `case'.  This breakage should not be necessary.
