I wanted to know which value to assign when a frame does not have
vertical scroll bars.  We could try with

  store_in_alist (alistptr, Qscroll_bar_width,
		  (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));

but I'm not sure whether that's what you meant.
