A lot of this code, judging from the report, is not working. Open source code is expected to work on new architectures and with new C compilers but clearly a lot of this code does not. Upstream does not "do a port" because Debian is or Fedora is doing a port. And if a new version of gcc breaks your code because it assumed old behaviour that "ain't broke" then it is broke. Binary versions might work, but source is what matters here.
