suppressing warnings seems to be a problem few programmers (present on
this list company excluded) manage to tackle successfuly:

	home% cd src/links-ape/
	home% sed -n 223,228p gif.c
	accept_code(struct gif_decoder *deco,int c)
	{
	 int k;

	 k=k; /* To suppress warning */
	 if (c>4096||c<0) return; /* Erroneous code word will be ignored */
	home%

Plan 9 has USED().  Interestingly enough, in the lunix version of Plan
9's libraries USED() works on a single argument only :)
