This kills the output from the case where "sockfd < 0" evaluates to
true for the last entry in ai, no (just above your second hunk), no?
In that case errno gets copied to saved_errno, and the old output
would do strerror(old_errno), but now you just print the log you've
gathered, and don't even look at saved_errno.
If this is intentional then you should probably kill the saved_errno
variable also, it's rendered pointless by this patch.
