I am compiling mkgmap with Sun javac with -Xlint:unchecked by commenting out the compilerarg definition in build.xml, and I get some warnings for unchecked calls and type conversions. I do not know Java well enough to fix these (I learned it before the generics were introduced and have not written much Java lately). I guess that some <classname> qualifiers would have to be added. Could someone please look at these? Marko
