   I don't think this is bogus. setf is a macro and is not needed at runtime
   because it has been expanded and compiled into winner.elc (I think you might
   mean defsetf but that is also a macro, so the same applies). gensym, on the
   other hand, is a function, so Emacs will need to know where to find it
   when it is called.

I do not believe so.  The only purpose of defsetf is to tell setf what
to do.  The expansion of the defsetf macro will only be called if setf
is called first, which requires cl to be loaded.  _No_ cl function
used inside the defsetf expansion will ever load cl, when called from
there.

Sincerely,

Luc.
