That patch does the "correct" option negotiation for AIX. RS6k's are kinda
werid in that respect. Below is a patch to fix the "stty raw" problem,
which I derived from my modifications to the beta4 code, which we
are still using in a production mode here at the U of I. If there is
interest, I can post the diffs to the telnetd from the beta4 source.
Also if someone could tell me what defines I can put in the code that
gnu autoconfigure will find for AIX 4.x I would be most appreciative :)
