Doesn't whether that's "right" or not depend on whether you are loading
the compiled or uncompiled versions? cc-mode was certainly not
_supposed_ to be loading cl (or cc-langs) at runtime when run compiled,
though for a time it did:


I can't say I understand all this cc-mode stuff, but I made the change
from cl to cl-lib in emacs-24, so if something needs fixing it
probably needs fixing there too.
