I got the following letter from Eric Goldman and appreciate with his comments.
Using curses is like wearing a "KICK ME" sign. No two versions are the same.
This will NOT go into my normal distribution because folks should be
encouraged to fix <curses.h>
sc compiled and ran fine on a VAX running 4.3 BSD at my site. However,
it compiled, but screwed up the nl()/nonl() stuff, when run on my MicroVAX II
running Ultrix 1.2; the same problem occurred on a VAX running vanilla 4.2 BSD.
I traced it to a bug in the nl()/nonl() definitions in /usr/include/curses.h
that appears to exist only in the 4.2 BSD and Ultrix 1.X versions of that file.
I suspect that someone had fixed those definitions on the 4.2 BSD system you
tested it on. (In fact, on a Sun 2 at my site running Sun UNIX 3.0 [basically
4.2 BSD with Sun enhancements], the nl()/nonl() stuff in /usr/include/curses.h
has been fixed [by Sun]. I haven't tried compiling sc on it yet, however.)
The following patch to sc.c is necessary for vanilla 4.2 BSD machines and
Ultrix 1.2 (and presumably Ultrix 1.0 and 1.1) machines:
*** sc.c Tue Jan 27 15:54:31 1987
--- sc.c.new Tue Jan 27 15:55:06 1987

Perhaps you should post it to comp.sources.d. Thanks.
