Ok.  I added:

I made it work when performing not only the clean install but
also package-reinstall or similar (i.e., updating the exsisting
emacs-w3m melpa installation) even in the condition where an old
w3m.elc is already loaded.  So, if Emacs says[1]

	You may want to update the emacs-w3m installation

when loading w3m.el(c), one could do it at ease (hopefully ;-).

[1] It will take place if `package-refresh-contents' runs and
archives the information about a new emacs-w3m package beforehand.
