[mkgmap-dev] [Patch v1] avoid wrong bearing results

Fri Nov 1 09:58:02 GMT 2013

Hi Gerd,

well done!
I like the way that the higher precision can be used step by step and we 
don't have to change the whole source code at once!

Does the change require more memory? I have seen two new byte fields in 
the Coord class.
