Using r1049 with this patch, quick-distance V2 and parallel V10 I had no
problems compiling great_britain.osm. Either the commits and patches
completely workaround the problems or the consecutive identical points
warnings have been suppressed as I had no warnings at all

A *very* brief check of the map shows no problems but I'll get chance to
test it over the next few days as I'm away for a short break
