The problem was always that CEDET provides a bunch of different
features. If you activate them all, people would complain that it is
'too much', and if you just activate the bare minimum, people would
wonder why certain stuff just doesn't work.

That's why in upstream there's semantic-load.el, which has several
functions to set up CEDET in various different ways, from the bare
minimum to absolutely everything. I guess we would have to find a
compromise for which features should be activated by default. Eric has
surely some ideas regarding this issue.

I guess a

(eval-when-compile (require 'semantic/find))

in semantic/analyze/fcn.el should do the trick?

I also noticed another error due to removed autoloads:
'semantic-tag-write-list-slot-value' isn't defined when the database is
saved upon exiting Emacs. An eval-when-compile won't work here, since
this is actually a slot value which is called from eieio. So I guess it
either needs an autoload, or 'semantic/tag-write' is required in
semantic/db-file.el ?
