Horrible, I know, but I remember getting bit by it.
Must be because it was a Microsoft product. Luckily it is very difficult to find a Xenix system now.
Unless you are writing very important software that everyone needs in order to get anything done, I wouldn't worry about portability to Xenix or any other relic OS.
