Re: libunwind changes

[Andrew Cagney <cagney at redhat dot com>]

Jan,

Yes, when working on local branch of up-stream code we also always work 
on getting those same changes committed up-stream.  For libunwind, I 
believe the earlier changes were submitted (or removed), and I see now 
that DMT, thanks to a gentle ping, is looking over them.  Can we get the 
changes you made commited upstream?  If you've the time, you could help 
DMT with the old changes he is examining.
