I use an entirely different approach.  I declare a fake malloc:

	void *my_malloc(size)
	unsigned int	size;
	{
	extern	char	*malloc();

		return((void *)malloc(size));
	}

and then whenever I use it I say something like:

	....
	extern	void	*my_malloc()
	ZAP		*zap_pntr = (ZAP *)my_malloc((U_INT)sizeof(ZAP));	

This shuts up lint except for the line in my_malloc where I cast from
char * to void *.  I figure that 1 ignorable complaint is better than
hundreds of them.
