Well, as small as possible, of course. That is what i get now:

That is cross-compiled for PowerPC and -O2. For my embedded target
i want to get much lower than that. I just have interfaces that are
known at compile-time; so - in my understanding - no need for DII.

Basically i want to achive a minimum CORBA environment
(http://www.omg.org/cgi-bin/doc?formal/02-08-01), however with
Event- and Naming-Service.

MinimumCORBA basically strips away DII, DSI and DynAny. Regarding
the Event-Service in this environment: Does Any really require
DynAny also?

omni3, compiled for x86 with -Os is

Which is better; however i'm striving for ca. 3 MB...
