I doubt anybody has any good ideas here. An alternative mailing list
for this question would be config-patches@xxxxxxxx It would also be
reasonable to bring this question up on the gcc developer's list,
gcc@xxxxxxxxxxxx

As far as I can tell, ia64*-hp-hpux* is the only target which supports
32-bit ia64 code at all.
I have no idea whether the default should change. For that you should
probably ask the union of the ia64 and HP/UX maintainers. According
to gcc's MAINTAINER files the ia64 maintainer is Jim Wilson and the
HP/UX maintainers are Dave Anglin and Steve Ellcey. They are all
responsive.
My tentative vote would be to flip the default for ia64*-hp-hpux* to
be 64-bit to match the other ia64 targets, to give it 32-bit libraries
as multilibs, and to add a configure option --with-model={ilp32,lp64}
to set the default model. But I don't know very much about either
ia64 or HP/UX.
