AW: [omniORB] Port allocation problem on windows (incl. patch)

Our system is a bit different in that it is (also) meant to run on user machines
and waits to be accessed by some client side. So now if the user accidentally
starts two instances things are bad (and we can't detect it which is more bad).

OK, I see that point.

That'll be sufficient for our system since we already inject some options via
argc/argv. I'm trying to provide such a patch and mail again.

Btw: The omniORBpy has the same problem so it'll also need such a parameter.
