Thanks. (but the javac from doesn't need this, so I was not sure)

Hmm, learning here as well.

I'm not sure if it is the above thing with namespaces but I had
something similar when I built DDD. Here I had to pass a flag to the
linker which is not part of the mainline gcc. 
I tried to build a gcj that understands this flat too, but I only
succeeded in the gcc.

Maybe I'll find out more.
