I don't remember the last time I wrote anything that worked on HP-UX; it's certainly not a platform I have any interest in supporting. I mean, geez, next you'll be complaining that it doesn't work on VMS.
If you're going to deal with freakish systems like this, then yes, you're going to have to go to the lowest-common-denominator. But that's no reason why those of us not stuck in the 1980s should care.
For any feature you care to consider, ABSOLUTELY ANY FEATURE YOU HAVE EVER USED, there exists a platform on which it does not work. That does not mean you should not write any code.
While I agree that from certain programming standpoints HP-UX leaves much to be desired it also happens to be one of the current dominant OSs of choice for big-iron Unix systems, and is therefore not an obscure "freakish" system.
My software works fine under HP-UX. You software should work under HP-UX as well.
