The byte-compiler is not that smart and doesn't fully recognize defuns
that are not at top-level. This one is "hidden" inside an if.
You could eval-and-compile the whole thing (defun and all) to make the
warning go away. But lisp-imenu-generic-expression is defined in every
Emacs since at least 21.1, so I don't see the point of the if, unless
it's an XEmacs thing, in which case featurep 'xemacs can be cleaner.
