I guess std::errc::state_not_recoverable is missing because
ENOTRECOVERABLE is missing from errno.h. So NetBSD-9 itself is too old
and a newer GCC is unlikely to fix it. But this code has not been
touched by upstream for some time so I wonder why it is suddenly
failing? Probably a pkgsrc patch like this would fix it:
