i don't want to change the licence/copyright, I just wanterd to know if the
2 licences are compatible and if i can modify the source, while keeping the
copyright ,notice. I added Paul Vixie (ISC) and you as authors (I use a
structure and some define from c-ares code), I added the fact that the file
comes from c-ares.
