Subject: Revert #20301, apparently the _SOCKADDR_LEN #define is
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=8cfab5ff7c21540622402ad6821ff3565a6c7ff5;p=p5sagit%2Fp5-mst-13.2.git

Revert #20301, apparently the _SOCKADDR_LEN #define is
important for IPv6 (Spider).  Since there is no way to
otherwise detect 3.X, use the hints.
