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
