It seems tha rev 110951 builds fine and rev. 110952 fails...

Attached is the differences... it looks that here is the "bug",

2012-11-19  Stefan Monnier  <>

+	* emacs-lisp/byte-run.el (defun-declarations-alist):
+	Allow a compiler-macro to be a lambda expression.
+
+	* 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.
+
  	* vc/diff-mode.el (diff-hunk): Don't make useless timers.
