[mkgmap-dev] multipolygon label

Hi Gerd, Please find attached a small patch that fixes a problem with the use of the label role in multi-polygon relations. Currently, if a node has the role of label but has no name or a different name from the polygon, a message is output saying the node will not be used. However, it is used anyway. The patch stops the override and does not display a warning for a node with no name. Cheers, Mike
