Installation of CNews on 3B1 (LONG)

[Ralph Russo]

In response to a couple of postings regarding installation of
CNews on 3B1:

I successfully installed CNews on 3B1 about 4 weeks ago.  It's running
now with no problems...

Attached to the end of this posting is a record of my answers to the
build script.  (My responses may be stupid in cases BUT,
they DO work :-)

BUT FIRST: There is one thing I might have done better: I responded
Yes to the question about "does my system have an ldiv() like the ANSI
one?" and the REAL answer is that the 3B1 doesn't.  The 3B1 version
returns a different value than the one cnews is expecting.

WHAT I DID TO FIX THE LDIV PROBLEM: I went into the file
cnews/libfake/ldiv.c and changed the name of the function from ldiv to
xldiv, built ldiv.o, Then, used the ar command to install the new
object (ldiv.o) into cnews/libcnews.a NEXT: Changed the call in
libcnews/ltoza.c from ldiv to xldiv. then rebuilt relaynews.

I THINK THE PRECEEDING DESCRIPTION IS CORRECT.  I DIDN'T TAKE
NOTES!!!!

ALSO - I'M NOT SURE I HAVE FOUND ALL CASES WHERE LDIV IS USED !!!!!

ALSO - I made no attempt to use shared libraries or to strip to
executables.

ALSO - I accidentally used the GNU GCC preprocessor (but, this
__SHOULD__ have no effect on the outcome HA HA)

ONE MORE ALSO - I did have to tweak a shell script or two and change a
couple of permissions here and there...

I'd be happy to provide anybody help in their porting effort!

C News by default assumes that all normal Unix programs can be found
in /bin or /usr/bin.  This is naive, especially on Berkeley-derived
systems where some standard programs inexplicably moved to /usr/ucb.
It would appear that /usr/ucb does not exist or is not needed
for normal operation on your system.  Is that right [yes]? 
Is there any other directory which should be searched to find
standard programs on your system [no]? yes
