`make' runs Emacs without loading user's customization, auxiliary
program, or third-party program.  Though no error or no warning
doesn't necessarily guarantee a code is complete, it sometimes
offers useful informations.  For instance:

,---- (Emacs 24.3.50)
| In end of data:
| w3m-form.el:2001:1:Warning: the function `show-all' is not known to be
|     defined.
| Wrote /Work/emacs-w3m/w3m-form.elc
`----

I guess the `show-all' function is that of outline.el, but Org-mode
doesn't seem to load it explicitly.  So, we may want to add autoload
or other for it (even if it is only for silencing the byte compiler).

`----

The first one (view-mode) is due to my fault, has already been
fixed.  (I wonder why the old code was working...)

According to Emacs' ChangeLog files, `split-window-sensibly' was
introduced in 2009-05-07, so it will be available in only Emacs
23 (July, 2009) and up.  But not in XEmacsen.  It means that we
have to put the lid on it for people who use such old (X)Emacsen
if `split-window-sensibly' is essential.  Is it allowed to do
like this?

(if (and w3m-form-textarea-use-org-mode-p
         (foundp 'split-window-sensibly))
    (split-window-sensibly cur-win)
  (split-window cur-win (if (> size 0) size window-min-height)))
