The binary works without any noticeable problem.

Well, it has a glitch: when the window is maximized, clicking on the
help menu item "about Emacs" brings out an alternative version of this
buffer which doesn't have the Emacs logotype, has a slightly different
phrasing and its links are no longer coloured.

But I have checked that this glitch also happens in the version of
Emacs built with libunicows, and it still appears in the trunk
version.  And it already appeared in Emacs-22.3 but I hadn't noticed
until now.  In any case, only under windows 98.

Observations:
- AppendMenuW is called through a function pointer and is a stub
(error 120), but this is handled by subsequent code.
- ExtTextOutW doesn't produce an error so, apparently, this function
is not a stub in windows 98.
- Again, the breakpoints I have set for the calls to the other unicode
functions are never reached before the Emacs window is opened and is
operative and then, after a while, I simply quit.

In a second build, I have tried using the unicows implementation of
AppendMenuW and I have noticed that the menu items tooltips no longer
show.

I have built an updated trunk version of Emacs with the same changes
applied and it works equally well.

Greetings,
