With the removal of libgcj, the only user of libffi in GCC is libgo, however there is now no maintainer listed anymore for libffi in the MAINTAINERS file, and the libffi subdir is a bit outdated compared to the libffi upstream repository (got aware of this by libffi issue #197). Who would be responsible now to update / review libffi patches, just the global reviewers, or should libffi be maintained by the libgo maintainers?
