Done in the updated patch below. Given that the other two are ia64 only
and not documented in md.texi, I don't think they need to be poisoned.
Otherwise, the patch is unchanged from the original submission:
[build] Move unwinder to toplevel libgcc
http://gcc.gnu.org/ml/gcc-patches/2011-06/msg01452.html
Unfortunately, it hasn't seen much comment. I'm now looking for testers
especially on platforms with more change and approval of those parts:
* Several IA-64 targets:
ia64*-*-linux*
ia64*-*-hpux*
ia64-hp-*vms*
* AIX:
rs6000-ibm-aix*
Thanks.
Rainer
