We have similar checks without the FIXMEs in the same source file. If we really want a FIXME here that should probably for the case when IPV6_PKTINFO is not found for whatever reason, but we also don't have any FIXMEs on failures resulting in ICMP over dgram not working at all (e. g., not allowed, that also can be not permitted). So if we want to start with that I think it would make sense to start from earlier failing fallback.
In fact, what I surely missed here is that if IPV6_PKTINFO is not defined then struct in6_pktinfo also should not be defined, I will resend with that changed.
