Attached is the Eclipse Java compiler I wrote for Ant.
Tom - I have vague memories of you having done the same thing at one
point.
ecj has been in rhug for some time now. Running it in-process as the
default java compiler makes for a wicked fast build system.
This requires the Ant patch that I recently sent to the list in order to
point the bootclasspath at the right libgcj.jar file.
I'd like to commit these changes (once I fluorinate ecj), but thought
I'd check to see how people feel about this...
Thanks,
AG

I'm currently looking into the whole ant + ecj thing, so I'll probably
end up committing these changes if it's alright with you.

Jesus, you weren't kidding! It's so fast compared to RHUG builds that
I didn't think it had done anything until I checked!

I've benchmarked it against jikes in the past as a stand alone compiler,
and this is faster.
So I think it's fair to say that for ant based builds, we'll compare
even more favorably against ant+jikes since we won't spawn processes.
