[mkgmap-dev] mkgmap r3665 complie error, removing road_class and road_speed made a non-routable line?

Thank you Gerd, that makes sense.

I was using routable linetype 0x01 because PINNS website stated that 0x01
(normally used to motorways) does not get over drawn by any other linetype
and I was adding a special BRIDGE linetype=0x01 because I wanted it to be
drawn on top of all other lines.

Since 0x01 is routable and I removed the road_class and road_speed, I made
it non-routable and hence the error occurred.

To fix this, I will have to use another non-routable linetype and make it
look like my 'other' rout-able BRIDGES linetype, and then my railroads
bridges will look similar to my routable road bridges.
