[mkgmap-dev] Roundabout checks

Hi, I wonder whether we could add a check that any highways joining onto a roundabout only do so at the end of way, and that no more than one way joins the roundabout at any given node? This would highlight roundabouts that do not adhere to the rule of having a separate node for each entrance and exit - I believe these cause the GPS to display the incorrect exit number when routing. I suspect this check would too complex to be done in a style file. Regards, Mike
