Provenance of Linux errno.h
Warren Toomey has a great groklaw article on the origins of errno.h in Linux.
You might think that since both the names and values of Unix errors
are fairly standardized it would be hard to distinguish whether a
similarity was coincidental or infringing copying. So SCO's claims
are, at first glance, hard to dismiss. But it turns out that it can
be proved beyond (I think) reasonable doubt that Linux did not copy
errno.h from SysV. Yet another SCO claim bites the dust.
