It's the best I came up with so far.  I can't use the width of the menu
bar: Try doing

(set-frame-parameter nil 'internal-border-width 36)

and you'll see what I mean.

BTW the Lucid and Motif builds _do_ report the same width for menu and
tool bar which is wrong with a non-zero internal border width.
