Re: libunwind changes

[Jan Kratochvil <jan.kratochvil@redhat.com>]

Andrew,

so far I did not try to push anything upstream.

I believe one should try to sync all the changes including the Alexandre
Oliva's ones etc.

Assuming this as a request I should start the patches separation and try to get
it all accepted upstream.  Except the PPC port so far, though, as this port is
still not in a healthy enough shape.


Regards,
Jan
