Hello Eli,

Just to clarify the point that -Q should or not prevent the shadowing:
it *should* prevent shadowing.

What I do in the init.el is that I remove from load-path the path to the
eieio bundled with Emacs, and I replace it with another one on some
cedet anonymous checkout.

So, if I have -Q this hacking of load-path does not occur, and shadowing
bundled module won't occur.

FYI, attached is load-path-to-cedet-svn.el which is loaded from my init file
to do the shadowing.

  Vincent.
