ZModem compile on A3000UX?

[Wendell Dingus]

I seem to remember a Commodore software person explaining how to do this
recently, but misplaced the message. In essence, how can I compile RZ and
SZ under Amiga Unix 1.1? I get all sorts of wierd compiler error messages.
Something about an implied change in Ansi C, etc... 
I've gotten two different versions of Zmodem source from various places to
no avail. The latest one was an updated release with Bix Zmodem extensions.
Using Kermit is becoming a pain, I want ZModem! :)
Thanks.
