I also think you should add a comment about the specific ordering of
this unwinder.  It has to come before the dwarf2 unwinder because GCC
doesn't provide proper CFI for the epilogue, right?


Right - I would like to have a way to suppress this unwinder, maybe
based on the producer string like other recognized dwarf2-frame
quirks, but we can worry about that later.  I hope it will be
unnecessary with GCC 4.5.

I would like that too -- maybe you can point me at an example?

I'm thinking that even if GCC 4.5 fixes the issue, people will
continue to use older GCCs for a while.
