From Felix Hartmann extremecarver at googlemail.com on Mon Dec 7 22:30:52 GMT 2009

Nope, also against clean trunk the patch does not compile for me:

     [mkdir] Created dir: d:\Garmin\mkgmap_svn_trunk\build\classes

     [javac] Compiling 317 source files to 
illegal start of expression
     [javac]             if(way.isBoolTag("unpaved") || 
     [javac] 1 error

d:\Garmin\mkgmap_svn_trunk\build.xml:71: Compile failed; see the 
compiler error output for details.
