[mkgmap-dev] Bogus warnings about intersected ways in multipolygons

Hi Marko

OK the directory overflows for that file because there are more than
64k blocks.  You can either reduce the size of the file or use the 
--block-size=1024 parameter to make the blocks bigger and so reduce the 
number.

The bug is that it doesn't trigger the error message when the directory 
overflows as it normally does.  It should give the message:

  "Too many blocks. Use a larger block size with an option such as 
--block-size=1024 or ..."

It should be possible to make mkgmap adjust the block size automatically 
- it does for the gmapsupp.img for example, which almost always needs a 
block size greater than 512 if there is more than one .img in it.
