  Henry Spencer posted a suggested fix for the Cnews problem on Uport SysV/AT.
  Basically, the offsetof() macro breaks PCC compilers. On microport you
  can simplify the expression by removing the first cast and the subtraction
  since the program will be compiled in the small memory model. Klugey but
  it works.

  Cnews works *GREAT* on microport 286-2.4!

  You have to fix spacefor however. The SysV.2 df does not take arbitrary
directories for arguments. It is relatively trivial to fix it up, but
it is site specific because you need to know about how you set up your file
systems. I'm including spacefor off my system at the end of this posting.
It is a slightly trimmed down version od the original. 
  On my system /usr/spool is a separate disk drive, so to change this to
work on your system you should make the argument to df be whatever filesystem
you spool stuff on. (Typically /usr on uPort setups) 
  If you spool news and uucp stuff on different filesystems, you would be
better off starting with the stock spacefor and modifying it.
  The only other caveat is that I put my news stuff in /usr/local/lib, so
if you put things in /usr/lib (blech...) you'll have to change the line
that looks for the config file. 
  
  Spacefor follows signature...
