- Allow running `/usr/bin/gcore' with provided but inaccessible tty (BZ

229517).
- Fix testcase for watchpoints in threads (for BZ 237096).
- BuildRequires now `libunwind-devel' instead of the former `libunwind'.
- Use the runtime libunwind .so.7, it requires now >=
    0.99-0.1.frysk20070405cvs.
- Resolves: rhbz#229517
- Related: rhbz#237096
