+	Factor out common code in generate-{c-,}file-autoloads-1 into new
+	function generate-autoload-ish-1.  \(I was originally going to use
+	this for custom as well but ended up thinking better of it.)
+	
 	* cus-dep.el:
 	* cus-dep.el (cusload-hash-table-marker): New.
 	* cus-dep.el (Custom-make-dependencies-1):
+	Cache the old computed values in custom-load.el and reuse them as
+	necessary, to speed up running cus-dep (which would take 25-30
+	seconds to do all files in lisp/*, lisp/*/* on my Pentium III
+	700).  Use `message' not `princ' to get correct newline behavior.
+	Output messages showing each file we do actually process.

+	Rewrite algorithm to be much faster -- cache calls to

+	Autoload early and only when update-elc has told us to.

-	* byte-optimize.el (byte-optimize-lapcode):
+	If no files need byte compilation, signal to update-elc-2 to do
+	any necessary autoload updating (using the file REBUILD_AUTOLOADS)
+	rather than doing it ourselves, which would be way slow.  Ignore
+	updates to custom-load.el and auto-autoloads.el when checking to
+	see whether autoloads need updating.  Optimize out many
+	unnecessary calls to file-exists-p to speed it up somewhat. (####
+	The remaining time is 50% or more in locate-file; this is
+	presumably because, even though it has a cache, it's still
+	statting each file to determine it's actually there.  By calling
+	directory-files ourselves, building a tree, and then looking in
+	that tree, we could drastically shorten the time needed to do the
+	locate operation.)
