Ok, first I should say, I'm a sometime GCJ hacker. I'm not heavily
involved with it, but I am heavily involved with GNU and so I use it a
lot.

So I have an interest here.

The next thing is: GCJ doesn't have a concept of JAVA_HOME. I don't
think jikes or kaffe or kopi has any such concept either.

So that means that JAVAC detection should be either via a normal
autoconf tool or something simpler, like the attached patch.

But that doesn't solve the issue of version selection. I think this
is a fundamental build issue: how do you choose which version of the
driver to build?

As I say, my view is that we should test the target java's version,
and not the version that is being used to run ant.

Would you (or anyone else) have any objection in principle to that?
