Yes, it'd make sense put a cross-reference there, or perhaps it's time 
to reorganize tz-link.htm (but that's a bigger project).  Might as well 
mention HP-UX while we're at it.  Further patch attached.

I think I'd rather leave that one out.  We don't have support links for 
anybody else (Android, Apple, Oracle, Red Hat, etc., etc.), and adding 
support links for everybody would be a maintenance burden for us and 
overkill for readers.

These days time zone support is all automated anyway, no?  (Here's where 
I duck to avoid tomatoes being thrown....).
