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.
