Problem building OpenJDK on a set-top box

[Jonathan Springer]

That's good progress, being able to build itself.  I should take a look 
at it.  It's still going to be interpreter-only (without porting), 
right?  Would it still be possible to add a compiler port (c1, opto) on 
top of it?

Thanks,

-Jonathan
