/me looks at the code

	/*
	 * Step 4: if |p - p0| < TOL then terminate successfully
	 */
	delta = fabs(p - p0);
	if (delta == 0.0)
		break;

Ok, I'll admit that the code does look broken, especially with regard to
the comment *in* the code.  

Is anyone from Caldera still maintaining this code or shall I create a
CVS module as part of LTP?
