True. But I accidently bumped into one of the following
definitions, in which the parameters still defined as having type 'int'
(the definitions below are corrected already):

(define-func gtk_aspect_frame_new
  GtkWidget
  ((string label)
   (float xalign)
   (float yalign)
   (float ratio)
   (bool obey_child)))

(define-func gtk_aspect_frame_set
  none
  ((GtkAspectFrame aspect_frame)
   (float xalign)
   (float yalign)
   (float ratio)
   (bool obey_child)))

(define-func gtk_progress_set_show_text
  none
  ((GtkProgress progress)
   (bool show_text)))

(define-func gtk_progress_set_activity_mode
  none
  ((GtkProgress progress)
   (bool activity_mode)))

(define-object GtkPlug (GtkWindow)
 (fields
  (GdkWindow socket_window)
  (bool same_app)))
