I don't know why there is a lclint.el file because the current emacs
environment (version 20 and probably 19.34) seems to work just fine.  You
just have to add an additional regex to make it fully understand the lclint
error messages.  The emacs folks (RMS) will probably update the sources to
automatically support lclint.  In the meantime, add the following into your
.emacs file.  In version 20, font-lock highlighting will work as well.

(eval-after-load
 "compile"
 '(let (
        ;; similar to the first regexp in compile.el (v20), but also looks
        ;; for a comma
	(lclint
	 "\\([a-zA-Z]?:?[^:( \t\n]+\\)[:(][ \t]*\\([0-9]+\\)\\([) \t]\\|\
:\\|,\\([^0-9\n]\\|\\([0-9]+:\\)\\)\\)")
	)
      
    (setq compilation-error-regexp-alist
	  `((,lclint 1 2 5)
	    ,@compilation-error-regexp-alist
	    ))
    ))
