It means though that we have to do some non-standard surgery in the
frame parameters area.  Note that x_report_frame_params inserts the
zero value automatically via

  store_in_alist (alistptr, Qscroll_bar_width,
		  (! FRAME_HAS_VERTICAL_SCROLL_BARS (f)
		   ? make_fixnum (0)
		   : FRAME_CONFIG_SCROLL_BAR_WIDTH (f) > 0
		   ? make_fixnum (FRAME_CONFIG_SCROLL_BAR_WIDTH (f))
		   /* nil means "use default width"
		      for non-toolkit scroll bar.
		      ruler-mode.el depends on this.  */
		   : Qnil));

What should we use instead?
