I successfully compiled unison v2.13.16 on HPUX 11i. Since this was a real pain in the ass, I thought it might be a good idea to make the binary available to others as well; it can be downloaded from http://stud3.tuwien.ac.at/~e9802701/unison-2.13.16-hpux.gz . It would be nice, if someone added a link to the download section. cheers, philipp
