I need to write an "errno.h" with constant values used by the FreeBSD kernel. My project uses exclusively the 2 clause BSD license. I expected to copy those values from FreeBSD errno.h. However, FreeBSD errno.h has 3 clauses. I'm a total newbie in licensing procedures so, it's not clear what to do. - Relicense the code as a 2 license BSD, because it's a derived work (prefered choice) - If the above is not allowed, ask the original authors of errno.h to provide an alternative 2 clause BSD license. Which choice is legally correct ? -- Henrique Dante de Almeida hdante@gmail.com
