This causes a strange compilation error:

  Loading lisp/mouse.el (source)...
  Eager macro-expansion failure: (void-function easy-menu-define)
  Eager macro-expansion failure: (void-function easy-menu-define)

  Error: void-function (easy-menu-define)
    debug-early(error (void-function easy-menu-define))
    (easy-menu-define help-mode-menu help-mode-map "Menu for Help mode." ...)
    require(help-mode)
    require(cl-extra)
    require(comp)
    advice--add-function(:around ... rectangle--region-beginning nil)
    advice-add(region-beginning :around rectangle--region-beginning)
    require(rect)
    load("mouse")
    load("loadup.el")

  Symbol's function definition is void: easy-menu-define
