It is the point of view to say "the OSM data is OK".
I ran r1475, r1502 and r1507 against exactly the same input files (the Geofabrik extract split into two tiles by splitter). r1475 produced no error messages at all. I admit I don't know whether r1475 might have done less error checking, but r1475 rendered the vineyards around Pinet correctly. I have seen plenty of bad quality data in OSM. For example, one of the multipolygon relationships which provoked an error message in r1502 and r1507, contained two outer ways, both with the same landuse tag. One way was closed, the other way was open and duplicated about half of the closed way. There is an ongoing debate about how much mkgmap should do in the way of cleaning-up the OSM data.
