I knew that, but I thought that

--8<---------------cut here---------------start------------->8---
;; Org-mode
(require 'org)
--8<---------------cut here---------------end--------------->8---

would add the association `.org' in `auto-mode-alist' on its own.

Anyway, adding the above `add-to-list' line (just after the `require org')
solved the problem of my colleague. Thanks.

Like you, I would not be in favor of such a solution. My goal is having a kind
of minimal `.emacs' file (this is the goal of Org2HTML.el) that can be used by
anybody using my Makefile.
