Enclosed are the few changes I made to gnu diff V1.07 to get it working on our
sgi iris 4d machines. Gnu diff works like bsd 4.3's, except it's missing the
"-D" command line option. I found gnu diff was required to get RCS V4
working.
You will also need a copy of the "alloca.c" file. Since I've posted that twice
in the recent few weeks (in the diffs for GNU Make and GNU Tar), I saw no
reason to consume any more network bandwidth.
The patches are short, and are to be made to the files "Makefile", "diff.h",
"diff3.c", and "util.c". Be sure to save any original versions before
installing any patches.
GNU software can be ftp'd anonymously from prep.ai.mit.edu. It can also be
anonymously uucp'd from tut.cis.ohio-state.edu. I believe you can find
detailed information in comp.sources.{bugs,d} or comp.archives on setting up
a UUCP link to them.
