Hm... it's also defined in subr.el by the looks of it:

  (defmacro declare (&rest specs)
    "Do not evaluate any arguments and return nil.
  Treated as a declaration when used at the right place in a
  `defmacro' form.  \(See Info anchor `(elisp)Definition of declare'.)"
    nil)

It seems that the actual declare form shouldn't ever get evaluated
because defmacro plucks it out when it encounters it.  Something strange
happening here, perhaps?
