Package:  emacs

	As of 20eb3d6e5262 [1], Emacs fails to build from a clean
	directory with the output like:

Loading /home/private/users/ivan/devel/emacs-2014-04-20-build/lisp/emacs-lisp/nadvice.el (source)...
Loading /home/private/users/ivan/devel/emacs-2014-04-20-build/lisp/minibuffer.el (source)...
Eager macro-expansion failure: (void-function defsetf)
Symbol's function definition is void: defsetf
make[1]: *** [bootstrap-emacs] Error 1
make[1]: Leaving directory `/home/private/users/ivan/devel/emacs-2014-04-20-build/src'

	Apparently, the “defstruct introspection” commit [2] is to
	blame, as it introduced to cl-macs.el:

	• the use of the ‘defsetf’ macro, defined in cl.el (not
	  currently required by cl-macs.el, and possibly leading to a
	  circular dependency);

	• two invocations of the ‘cl-define-compiler-macro’ in the
	  “Structures.” section /prior/ to its definition in “Compiler
	  macros.” later in the same file.

	The first issue could be solved by simply replacing defsetf by
	gv-define-simple-setter.  The solution for the second is to move
	these two invocations below the definition of the macro.

PS.  And since when using periods in ‘;;; ’-headings within the code
	became a convention, BTW?
