Sorry, I've only just had a chance to look at this.

As far as I can see, as well as being reported in July 2005, it was
fixed then as well. omniORB 4.0.7 changes the #ifdef you mention:

The #ifdef now says 

#if defined(__GNUG__) && (__GNUG__ < 4) || defined(__DECCXX) && (__DECCXX_VER < 60000000)

I'm also bemused by the fact that you say the issue affects omniORB
4.1.0. That doesn't even have a friend declaration there at all, because
it no longer has the tcParser helper functions.

Can you post some IDL that definitely exhibits a problem, the version of
omniORB it's a problem with, and gcc's output?

Cheers,

Duncan.
