OK, we can wait awhile to see what happens on that.

Yeah. FTR, I'm out of the HP-UX game: due to a hardware failure,
I can no longer boot that installation. I would have preferred to
keep pademelon, with its pre-C99 compiler, going until v11 is EOL,
but that ain't happening. I see that EDB are still running a couple
of HP-UX/IA64 animals, but I wonder if they're prepared to do anything
to support those animals --- like, say, fix platform-specific bugs.
Robert has definitely indicated displeasure with doing so, but
I don't know if he makes the decisions on that.
I would not stand in the way of dropping HP-UX and IA64 support as of
v16. (I do still feel that HPPA is of interest, to keep us honest
about spinlock support --- but that dual-stack arrangement that IA64
uses is surely not part of anyone's future.)
I have no opinion either way about Solaris.
