PJ over at Groklaw is calling for anyone who has access to the Unix SysV r.4.2 MP errno.h file. She wants to see a comparison with the post USL v. UCB Unix/BSD litigation. so that would be BSD 4.4 or better. Anyone have access to such a version? She's trying to pick apart someone's outrageous claim. Why? I don't know. He's on third. Thanks, Jack
