[mkgmap-dev] Commit: r1058: Add means to flag node as being discarded.

Version 1058 was commited by markb on 2009-06-03 17:34:04 +0100 (Wed, 03 Jun 2009) Add means to flag node as being discarded. The goal here is to be able to call getOffsetNod1() without bombing even though the routing will be broken because the node has been discarded.
