HELP!!! Can't Compile Netnews Code

[guest account]

I am having problems getting the Netnews software up and running
on my system.  I am using a Zilog System 8000.  The problem
code appears to be located in 'readr.c', 'visual.c' and 'expire.c'
this prevents me from being able to compile the critical
program 'readnews'.  Apparently, there aren't very many
people out their running System III, and my newsfeed group,
'philabs' hasn't been able to help me.  They've never seen
the problems I'm having before.

There is an include file 'setjmp.h' which my system doesn't
have.  Following is a typical error.

I cannot find setjmp and longjmp defined anywhere.  

Thanks in advance for any help.
