Thank you.
About downcase and upcase, what you say and your code are correct.
So I installed your code to emacs's CVS repository.
Soon cc-mode maintainer will also install it to cc-mode's CVS repository.
2007-04-09 Paul Curry <dashteacup@gmail.com> (tiny change)
* progmodes/cc-subword.el (c-downcase-subword, c-upcase-subword):
Don't move point if ARG is netagive.
About capitalize, I've written my own code based on your code; and
installed it.
First of all, in subword, I cannot find expected behavior of capitalize,
which all of people can agree with. As you wrote my old is wrong because
point moves with netagive argument. This is obvious. However, I wonder
which character should be upcase when a netagive argument is given.
I'd like to explain why I modify your code here:
Consider doing "-3 M-c" at xxx.
^ point is here.
[With your original code] efg bceFghi xxx => Efg BceFghi Xxx
[With my modified code] efg bceFghi xxx => efg BceFghi Xxx
[With real capitalize-word] efg bce Fghi xxx => efg Bce Fghi Xxx
I think my modified code is rather similar to the real `capitalize-word'
than your original code. If you have strong objection, please, tell me.

* progmodes/cc-subword.el (c-capitalize-subword): Implement
better mimic the behavior of `capitalize-word'. They no longer
move point with a negative argument.
Based on code by Paul Curry.
(defun c-capitalize-subword (arg)
"Do the same as `capitalize-word' but on subwords.
See the command `c-subword-mode' for a description of subwords.
Optional argument ARG is the same as for `capitalize-word'."
(interactive "p")
(let ((count (abs arg))
(start (point))
(advance (if (< arg 0) nil t)))
(dotimes (i count)
(if advance
(progn (re-search-forward
(concat "[" c-alpha "]")
nil t)
(goto-char (match-beginning 0)))
(c-backward-subword))
(let* ((p (point))
(pp (1+ p))
(np (c-forward-subword)))
(upcase-region p pp)
(downcase-region pp np)
(goto-char (if advance np p))))
(unless advance
(goto-char start))))
