x-parse-geometry (non-NS variant) calls XParseGeometry.  This may not be 
available.  But the W32-prt has an implementation.

It seems as ns-parse-geometry expects "top left with height", i.e.:

(x-parse-geometry "10 5 80 40")
((top . 10) (left . 5) (height . 80) (width . 40))

I don't know where this type of geometry is specified, but we could support 
both (if there is a space in the string, it is NS-style, if there is a +, -, x 
orX, it is X-style).

We could move the W32-version of XParseGeometry somewhere common (where?) and 
use that.
Or we can rewrite x-parse-geometry in lisp.

Suggestions?
