- Subject: patch 1 for diff.c
- Date: 13 Mar 88 11:41:50 GMT
- Organization: Swedish Institute of Computer Science, Kista
-
-
- Here are some (relatively minor) fixes for the diff program that was recently
- posted in comp.sources.amiga.
-
- They fix:
- strange behaviour if you do not invoke diff with
-
- diff -c
-
- I consider this to be a minor bug as a non context diff is next to
- useless.
-
- More imortant: if you do a diff between an empty file and a non
- empty file, then the old version will output the diff but it will
- also output an error message, saying that it can't find the first line
- in the empty file.

- [ Added the above fixes to diff.c - KED 03/24.88 ]
- [ Compiled using Lattice v4.01 by just saying "lc -L diff". ]
- [ Get a fair number of compiler warnings about function type ]
- [ mismatches (probably voids) ... ]
