face font in c-mode when adding new keyword

[Rami A]

Hi,
I am trying to customize some added words to be colored differently from the 
default face-font colors.

This is what I am doing:

(defconst lconfig-font-lock-faces  
  (list 

   '(font-lock-function-name-face
     ((((class color)) (:foreground "DarkBlue"  :bold t)))) 

   '(font-lock-constant-face
     ((((class color)) (:foreground "Black"     :bold t)))) 


   '(font-lock-builtin-face 
     ((((class color)) (:foreground nil))))

   '(font-lock-preprocessor-face
     ((((class color)) (:foreground nil))))

   )
  )
(autoload 'custom-set-faces "font-lock" "Set the color scheme" t)
(autoload 'font-lock-fontify-buffer "font-lock" "Fontify Buffer" t)
(progn (apply 'custom-set-faces lconfig-font-lock-faces)
       (add-hook 'c-mode-common-hook 'font-lock-fontify-buffer)
       (add-hook 'emacs-lisp-mode-hook 'font-lock-fontify-buffer)
       )
(global-font-lock-mode t)

(font-lock-add-keywords
 'c-mode
 '(
   ("^#[ \t]*\\(ifdef\\|else\\|ifndef\\|if 
!?defined\\|if\\|elif\\|endif\\|ident\\).*$" 1 font-lock-constant-face)         
         ;#defines 
   ("\\(^#[ \t]*define\\|^#[ \t]*include\\|^#[ \t]*undef\\).*$" 1 
font-lock-function-name-face)                                     ;other #s 
 )
)


unfortunately when opening a c file I see  #include and #define being black 
colored. Although they should match the regular expressions and turn to dark 
blue.
Also #ifdef and #endif is in light dark color and not bold.

Any help is appreciated.
