I did 2 comparisons with the output from 2 runs:

With mkgmap/trunk r2916
With mkgmap/branches/high-prec-coord r2930 and your patch

First, I compared the output of trunk to the output of branch, using the 
finland.osm.pbf from Geofabrik dated today, 02:16 UTC.

There were 2 differences:

(a) Variation of the coordinates in the 13 old-style messages
(b) Addition of 10 new-style messages

This was to be expected.

What was not expected was the difference 13 vs. 10. To diagnose it,
I performed another comparison within the output of the patched branch.  
Many of the "old" messages had direct counterparts in the "new" 
messages, but some "new" messages for "old" messages were missing, and 
some were extra (only "new" message for the way, no "old" one).

In my previous message, I listed the OSM way IDs for both cases. I fixed 
one error (for one extra "new" message) in the OSM database, but I left 
the others intact, so that we will have some errors in the next 
finland.osm.pbf to check against.
