Hmm, what about the following one?
And could someone who is familiar with the W32 (or NS) port help us
make these functions consistent with the X11 version? Otherwise elisp
programs that use these common functions (unconsciously) relying on
platform-specific behavior will not work as intended on other
platforms.
(Actually, some users have sent me "bug reports" that the behavior of
display-pixel-width/height on the Mac port is "wrong" for the reason
that they do not return the same values as the NS port, whereas those
in the Mac port behave consistently with those in X11.)
