It's a bug in Emacs-23 that is not present in the current trunk.
To reproduce in emacs-23 branch:

cd lisp
make autoloads
touch cedet/semantic/decorate/mode.el
make autoloads

Now there is a duplicate entry for mode.el in cedet/semantic/loaddefs.el.
I guess it is a bug in autoload-find-destination or
autoload-file-load-name that has since been fixed.

The timestamps in 23.3b are indeed messed up. I was going to suggest
some kind of fix involving touching various files, but frankly it is
probably a whole lot simpler to simply start from the 23.3a tarfile, and
just patch the etc/grammars directory with that from 23.3b, if you care
about having those files. Or distribute a separate package
emacs23-something that just adds them to an existing installation. Then
zero extra build time! :)
