I haven't been able to build the ia64 libunwind either, IIRC. I did
send some patches at the time that fixed some of the problems (that
got checked in), but there was one problem I didn't know how to fix
(it involved writing the implementation of a hook, or something like
that).

Just for the record, we use 0.98.5 for our production builds at AdaCore.
Not sure which version Tristan used, however.

Honestly, I do not know. I relied on code that was already written,
and I just plugged libunwind instead of using the system-provided
libunwind library.

If you can make it work, and it makes things simpler, why not (Jan
is the maintainer, so his decision, though). I think it might have
a nice side-effect, because we'd embed the code in GDB, rather than
require a libunwind library to be available on the host system.
