A 25 x 50 pixels window might look a bit small but 500.0 x 250.0 work
here.  With X things get more complicated but they should work there
too.  The major problem is and will remain NS: If with emacs -Q, you
evaluate

(progn
  (setq frame-resize-pixelwise t)
  (setq frame-inhibit-implied-resize t)
  (make-frame '((width . 1200.0) (height . 600.0)
		(font . "-*-Courier-normal-normal-normal-*-17-*-*-*-m-0-iso10646-1"))))

what does

(cons (frame-text-width) (frame-text-height))

return?

You should acquire that knowledge.  If there are any problems, Eli will
help (I won't because I'm misconfiguring).  The more people build on
Windows, the sooner we will be able to catch errors there.  As things
stand, too many people wait for the next release of ...

... and if Dani picked up a bad moment, we might get floods of errors
for something that was broken (and maybe even fixed) some time ago.

And I forgot to mention one aspect: You might then even be the first to
regularly build Emacs on both Windows and NS.  While this probably won't
give you any bonus points in this community, it still might be
interesting to get first hand experience with comparing the behavior of
Emacs on the two major proprietary systems.
