It will significantly improve S/N ratio in the make log.  I think it's
worth doing.

One note: if we care only the warnings at "make", similar result will be
obtained by adding these lines in lpath.el:
(autoload 'font-latex-add-keywords "font-latex")
(autoload 'font-latex-update-font-lock "font-latex")

(It seems that `declare-function' and `defvar' in lpath.el are not
effective in this way, unfortunately.)
Of course this is just a makeshift and not a proper solution.

Bye,
