Will do.

BTW Steve contributed back a patch which fixed a cross-development
problem in OmniOrb3's build system, but never got a response to his post,
http://marc.theaimsgroup.com/?l=omniorb-list&m=100872863312025&w=2
Can you comment on whether that patch can be accepted into the main tree?

Thanks!  He's updated his page with the result; in short, it says
    / # ./eg2_impl  -ORBtraceLevel 40 
    omniORB: strand Ripper: start.
    omniORB: scavenger : start.
    omniORB: gateKeeper is tcpwrapGK 1.0 - based on tcp_wrappers_7.6 
    omniORB configuration file: /etc/omniORB.cfg either does not exist or is not a file.
    omniORB: The omniDynamic library is not linked.
    omniORB: Initialising incoming rope factories.
    omniORB: throw INITIALIZE from objectAdapter.cc:182
    Caught CORBA::SystemException.

Hmm, does that mean I have to set the OMNIORB_USEHOSTNAME_VAR environment variable,
or something?
Suggestions welcome (I *do* plan to get the debugger working
sometime on this platform, honest!)
