I’ve just committed:

  https://bitbucket.org/xemacs/xemacs/changeset/2c20bc575989

which addresses the problem you reported. I’ve also committed:

  https://bitbucket.org/xemacs/xemacs/changeset/a944c124b2d3

which addresses a separate problem that I need to fix in order to get
emacs-w3m to compile (fair enough, glad to have the opportunity to fix it). 
I, however, also need the following change to W3M to get it to compile, I’m
surprised you’re not seeing it (the problem was an interaction of
lexical-let and compile-time defsetf expansion).
