It seems that arguments passed to `mapc' contain the symbol
`w3m-session', however I don't see the code that uses such one.
Could you try debugging to get the Lisp backtrace?  To do that,
load the w3m-session.el file (not the w3m-session.elc file) by
`M-x load-file RET', perform `M-x toggle-debug-on-error RET',
type `M-s', and then,  send the contents of the "*Backtrace*"
buffer to the list.  It will help us to investigate the problem.

`jao-w3m-go-to-linknum' seems to need to load w3m-lnum.elc by
itself since the `w3m-link-numbering-mode' variable that is first
used in the function is not autoloaded.  For example:

(defun jao-w3m-go-to-linknum ()
  "Turn on link numbers and ask for one to go to."
  (interactive)
  (require 'w3m-lnum)
  (let ((active w3m-link-numbering-mode))
  ...

Otherwise, simply add this line in your ~/.emacs-w3m.el file:

(require 'w3m-lnum)

Looks good, except for `jao-w3m-go-to-linknum'.
