Should be possible for me, thank you!

Exactly, it is a 32bit ia64 ELF ABI, not x86 (would have different byte
order, and would suggest HP-UX runs on x86 ;) ). It is the default
compiler output (both aCC and gcc) for backwards compatibility.
Did have a discussion with Steve Ellcey (gcc-dev at HP) to add
'ia64w-hp-hpux*' for 64bit default, and leave 'ia64-hp-hpux*' for 32bit
(both multilib-able).

AFAICS, it is the only exception to "*64*" being 64bit.
But ok, seems I'll have to mask gcc-4.3 even for hppa-hpux anyway.
