Hi Leonid!
Can you take an eye?  My next steps will be to add switch to jcod/jasm so they will use the original dual stream logging or not. Then I will add the stdout capability to jasm/jcod and will turn the dual stream logger off by default.
Last step may be to remove the dual stream logging. And that is the question on you. If you wish to keep the dual stream logging for compilers as optional, then - by current impl, the nasty prints/printe methods will remain. If you will be rather happy to remove dual stream logging completely, then the nasty prints/printe wil lbe gone. Actually whole unhappy DualStreamLogger will be gone, which sounds tempting.

I'm in favour of dropping it and log to stderr only, but it may break older consummers... so Most likley lets keep it optional, and remove in some far future?
