Q.  Since your code is really not implementing the linear time algorithm, is
there a significant advantage to using your code over the Lengauer/Tarjan
algorithm?

prefer basing GCC on algorithsm that are widely used/understood than those
which are relatively obscure.

The algorithm you're implementing is, err, highly complex -- after a half
dozen or so attempts, I still don't have a handle on it, which is a source
of concern.

Typically we put variable names in all-caps.
