Version 1273 was commited by markb on 2009-10-10 14:37:05 +0100 (Sat, 10 Oct 2009) Issue warning if a roundabout is also tagged as reverse oneway. Given that the roundabout's direction is determined by the order of its points, the oneway tag should be considered superfluous. However, if it has been tagged as reverse oneway, it probably means that the roundabout has been drawn backwards. To help identify those backward roundabouts, we now issue a warning if a roundabout has been tagged reverse oneway.
