Martin, I've fixed #1032 with a variant of the patch you sent.

The other issue, about tooltip-show modifying
tooltip-frame-parameters, seems deliberate. tooltip.el defines a
function tooltip-set-param with the explicit intent of modifying its
argument alist, and `tooltip-show' copies `tooltip-frame-parameters'
with copy-sequence, instead of copy-alist, and then uses
`tooltip-set-param' on it.

I can only imagine the idea was that `tooltip-frame-parameters' should
not contain misleading (fore|back)ground-color entries that weren't
really applied while creating the tooltip. Still, it seems weird to
modify under-the-hood a customizable variable.

Package: emacs,w32
Version: 23.0.60

default-frame-alist affects tooltips on Windows, but the background of
the tooltip window is not affected.

With

(setq default-frame-alist
      '((background-mode  . dark)
	(background-color . "black")
	(foreground-color . "white")))

the tooltip text foreground is white, but the background is still the
default lightyellow, so the text is not visible.
