libunwind build failed on Red Hat RawHide: autoconf-2.60-4.noarch It is due to a change: * Major changes in Autoconf 2.59c ** @top_builddir@ is now a dir name: it is always nonempty and doesn't have a trailing slash. Similar change will be made to ac_top_builddir in a future release; the old style value, which matches (../)*, is (and will continue to be) available as ac_top_build_prefix.

Jan, fyi, upstream is: https://savannah.nongnu.org/projects/libunwind/ and mailing list https://savannah.nongnu.org/mail/?group=libunwind I wonder if pushing as an upstream bug would be a better way of tracking this? Anyway feel free to commit here. Tks for this!
Committed, pushing upstream was now offered on #accu by mcvet.
