it turns out that "s_addr", the name of the variable, is a macro under
Solaris that expands to "S_un.S_addr", resulting in these syntax errors.
This problem was fixed in commit 0c1b6ab in the collectd-4.10 branch and
will be merged to 5.0, 5.1 and master in a bit.

It looks like Solaris is missing this struct. Since all extension
headers are being ignored, we should be able to fall back to a
self-defined struct like this one:

  struct ip6_ext
  {
    uint8_t ip6e_nxt;
    uint8_t ip6e_len;
  };

Best regards,
