Crap. I looked that up, but it didn't seem to exist; so I didn't use it. 
Either I screw that up or it just wasn't there with GCJ 3.x.
Thanks, I'll add that.

Really? I have different experience. As higher the optimisation, as 
bigger the executables... Depends on the strengh of the optimisation.
Anyway, it doesn't make big changes :-) What we really need is the 
ability to remove AWT/Swing and XML from the binaries when not needed. 
That would drastically reduce the binary size...

Yes, -O2 should really have been there...
