FreeBSD diff direcotry is /usr/src/gnu/usr.bin/diff . It refers to /usr/src/contrib/diff for diff sources. It seems FreeBSD apply a patch to GNU diff to get an option 'o' to get a old-style output. Applying a patch on a GNU app does not become BSD unless you write it from scratch. In my past experience, the GNU ncurses and Flex (http://flex.sourceforge.net/) are simple not compatible with FreeBSD even though Flex is licensed under BSD. I wanted to know whether the GNU cmp is also the same fate other than the license because all these GNU tools comes in one package, Diffutils. I was wondering why FreeBSD wrote their own version of cmp. If it just the license, then that's fine. I prefer the BSD versions of diff, etc. when available.
