[mkgmap-dev] additional arcs patch

From Gerd Petermann gpetermann_muenchen at hotmail.com on Wed Feb 26 07:16:38 GMT 2014

Hi Andrzej,

thanks again for testing. I am pretty sure that the patch has an influence 
on routing, but the results are probably not always better.
I found a few errors in it until now and I am working on an improved version.
