From a061e592f5be6deb9bd609a060f006836ce07b72 Mon Sep 17 00:00:00 2001 From: divverent Date: Mon, 3 Aug 2015 16:25:36 +0000 Subject: [PATCH] Compile with IPv6 support by default Invert logic of SUPPORTIPV6 define by changing to NOSUPPORTIPV6. Include commented-out entry in makefile to allow for disabling IPv6 support should the user be burdened by their operating system.
