I have a similar problem with Multi_key. I've defined "keycode 115 =
Multi_key" using xmodmap and it works everywhere, except in emacs as
its own X11 window. emacs in a text terminal is fine.

emacs as X application says:
<Multi_key> is undefined
when I press the key.

That's on NetBSD-current/amd64 also with current pkgsrc, in case it
matters, but I have this issue for a long time.
