So, new information.  The approach of using ST_SnapToGrid to avoid these
problems won't work on the the ST_LineToCurve function tests, because it
doesn't yet support curved geometries.  My naive solution is to remove
the tests until ST_SnapToGrid can be updated.  What I haven't seen are
the results of a failed regress_ogc test.  Could someone post these?
