what you are describing in 3) - Ant compares the dates of the files and
passes all sources which are newer than the corresponding class files to
javac (or whatever compiler you use)

jikes is reported to be better when it comes to dependency-handling. But I
can't tell you, I'm currently only doing "full" builds with ant (clean all
class files before compilation).

Ant does that - but I don't know what javac does after it get's passed some
arguments...
