- Subject: removing USG tests from diff
- Message-ID: <9211110722.AA09333@cygnus.com>
- Sender: gnulists@ai.mit.edu

- In a never ending crusade for cleaner code, I have removed all tests for
- USG from the code for GNU diff 2.0. This is done since unequivocably
- testing for USG isn't really possible, and generally not the right thing to
- do anyway. But you already knew that....
-
- Unidiffs to diff 2.0 follow....

- david d 'zoo' zuhn | There is great disorder under the heavens,
- cygnus support | and the situation is excellent.

- + * system.h: get rid of tests for USG, change to the correct feature test
