Make does still work with java, sort of.

Each x.java file will produce at least an x.class file, which can be used as
a target for make

e.g.

x.class : x.java
	javac x.java

But the problem is that javac is java, so there is a large runup time
 - javac *.java is a lot quicker than for x in *.java;do javac $x;done.

This is the problem ant tries to remedy, I believe.

We have a complicated build process here, which consists of various makefiles,
some of which call ant to do java stuff - probably not the most efficient
way to do stuff, but it works.
