+
+	* x-misc.el (device-x-display):
+	Provide this function, documented in the Lispref for years, but
+	not existing previously.  Thank you Julian Bradfield, thank you
+	Jeff Mincy.
+
+2010-12-30  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* simple.el (assoc-ignore-case): Remove a duplicate definition of
+	this function (it's already in subr.el).
+	* iso8859-1.el (char-width):
+	On non-Mule, make this function equivalent to that produced by
+	(constantly 1), but preserve its docstring.
+	* subr.el (subst-char-in-string): Define this in terms of
+	#'substitute, #'nsubstitute.
+	(string-width): Define this using #'reduce and #'char-width.
+	(char-width): Give this a simpler definition, it makes far more
+	sense to check for mule at load time and redefine, as we do in
+	iso8859-1.el. 
+	(store-substring): Implement this in terms of #'replace, now
+	#'replace is cheap.

+
+	* update-elc.el (lisp-files-needed-for-byte-compilation)
+	(lisp-files-needing-early-byte-compilation):
+	cl-macs belongs in the former, not the latter, it is as
+	fundamental as bytecomp.el.
+
+2010-12-30  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* cl.el:
+	Provde the Common Lisp program-error, type-error as error
+	symbols. This doesn't nearly go far enough for anyone using the
+	Common Lisp errors.
+
+2010-12-29  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* cl-macs.el (delete-duplicates):
+	If the form has an incorrect number of arguments, don't attempt a
+	compiler macroexpansion.
+
+2010-12-29  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* cl-macs.el (cl-safe-expr-p):
+	Forms that start with the symbol lambda are also safe.
+
+2010-12-29  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* cl-macs.el (= < > <= >=):
+	For these functions' compiler macros, the optimisation is safe
+	even if the first and the last arguments have side effects, since
+	they're only used the once.
+
+2010-12-29  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* cl-macs.el (inline-side-effect-free-compiler-macros):
+	Unroll a loop here at macro-expansion time, so these compiler
+	macros are compiled.  Use #'eql instead of #'eq in a couple of
+	places for better style.
+
+2010-12-29  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* cl-extra.el (notany, notevery): Avoid some dynamic scope
+	stupidity with local variable names in these functions, when they
+	weren't prefixed with cl-; go into some more detail in the doc
+	strings.
+
+2010-12-29  Aidan Kehoe  <kehoea@parhasard.net>
+
+	* byte-optimize.el (side-effect-free-fns): #'remove, #'remq are
+	free of side-effects.
+	(side-effect-and-error-free-fns):
+	Drop dot, dot-marker from the list.
