Not sure how I feel about that.

I also have just noticed that while POSIX says "[EAI_SYSTEM] A system
error occurred; the error code can be found in errno.", which IMHO
clearly says errno must be != 0,
https://man7.org/linux/man-pages/man3/getaddrinfo.3.html says
"EAI_SYSTEM Other system error, check errno for details.". I guess the
later could accept errno == 0, meaning "no details".
