Replaced POP() with STACKADJ(-1) on lines where the result wasn't used. The two are semantically equivalent, but the first triggered a compiler warning about an unused variable. Note, the preceding steps had already accessed and decreffed the variable so the reference counts were fine.

/* hypot() replacement */

	double yx;

		y = temp;

	if (x == 0.)

	else {
		yx = y/x;
		return x*sqrt(1.+yx*yx);
