From: Paul Eggert <[email-masked]>

Starting with trunk rev 110952:

	revno: 110952
	committer: Stefan Monnier <[email-masked]>
	timestamp: Mon 2012-11-19 16:30:55 -0500
	message:
	  * lisp/emacs-lisp/byte-run.el (defun-declarations-alist):
	  Allow compiler-macros to be lambda expressions.
	  * lisp/progmodes/python.el: Use cl-lib.  Move var declarations outside of
	  eval-when-compile.
	  (python-syntax-context): Add compiler-macro.
	  (python-font-lock-keywords): Simplify with De Morgan.

"make bootstrap" fails for me (Fedora 17, x86-64, GCC 4.7.2) with
the following "make" output.  The failure is still there in trunk
rev 110959, the current rev as of this writing.

if test "no" = "yes"; then \
  rm -f bootstrap-emacs; \
  ln temacs bootstrap-emacs; \
else \
  `/bin/pwd`/temacs --batch --load loadup bootstrap || exit 1; \
  test "X" = X ||  -zex emacs; \
  mv -f emacs bootstrap-emacs; \
fi
