The sizes looks ok. They're inline with the ones that I saw
a long time ago. Around 80% larger than ones for OmniORB.

The only strange thing is that these are ACE only. You need 
to add TAO, and the executable size most likely will double.

I do not think so. You are removing RTTI that takes some space,
and is hardly used.

This is good.
