Imenu does not work with C/C++ mode in recent trunk

["angelo.graziosi@alice.it" <angelo.graziosi@alice.it>]

In my init file I have:

;; c-mode
(add-hook 'c-mode-hook
	  '(lambda()
	     
;; RET with automatic indent
	     (local-set-key [13] 'c-return)

	     ;; 3 
spaces for indentations
	     ;(setq c-basic-offset 3)

	     ;; No indent for 
open bracket
	     (c-set-offset 'substatement-open 0)

	     ;; Add index of 
func. to menu bar
	     (imenu-add-to-menubar "Functions")
	     )
	  )

[...]


(setq imenu-auto-rescan t)


and so on for C++, F90, Fortran, SH... modes.

But 
with recent trunk, clicking on "Functions" item on menu bar has not effects. 

The last trunk I can test with which Imenu works is rev. 104859.

With other 
modes Imenu works.


Ciao,
