One other thing that we've found over the years is that pointer arithmetic on the RC processor is extremely costly. You may want to look at the .lst file that is generated when you build to see how much assembly is generated for pointer operations that you wouldn't bat an eye at on a desktop computer.

You may be better off storing an array of points as opposed to a linked list. If your points are sequential, there's no need to keep anything other than a simple index variable. If you're going to jump around inside the array, you'll need at least a second variable to index to your next point.
