I generated the same map with the only difference being this patch. The
file was a little smaller:
-rw-r--r-- 1 marko marko 36888576 22.9. 09:01 gmapsuppa.img
-rw-r--r-- 1 marko marko 36510720 23.9. 14:06 gmapsupp.img

Routing seems to be unaffected. I tested the same route, both bicycle
(253 km) and car (204 km).

There are a few differences between the generated gmapsupp.img if I enable
assertions. The files are of the same size, though. Come to think of it,
the differences could be attributed to --max-jobs. But the diff of hexdump
is only 64 lines, or 16 differing 16-byte blocks.
