I was upgrading and ran in to this, I need to get the server back up so any help would be GREAT.
I was also trying to deleate the ircd.conf that make config make so i could use the default but for the life of me i can't find it.
Not sure if this is causeing the error or not.
Thanks inadvance

can this be a gcc prob?
