Hi Gerd & Carlos

I've found the problem and attach a patch which reduces the Subdivision
line limit to 254.

Subdivisions/areas have a set of limits, one of which was <= 255 lines.
These lines can be of any type including roads. When --route, a
reference to each line/road part is created, but these are numbered
from 1, so the 255th line in a SubDivision is numbered 256 as a road
segment and this can't be represented as a byte in the NET structures.

It looks like this problem has always been there, but is most likely to
manifest itself in areas with mostly roads.
