21.5-b26: autoloads already loaded errors?

[Raymond Toy]

I've noticed that 21.5-b26 complains a lot about autoloads already
loaded.  This didn't happen before with earlier versions.

I think this happens because I have in .xemacs/xemacs-packages/lisp
modified versions of packages that xemacs already supplies.  For
example, I have a personal, modified version of pcl-cvs.

Is this expected behavior.  It doesn't seem to affect operation, but
it's a bit annoying and disconcerting to get a Lisp backtrace
everytime I invoke an autoloaded function for some package which I've
intentially shadowed.
