Hi All, OpenVPN 2.3.4 will currently throw a warning of "NOTE: setsockopt TCP_NODELAY=1 failed (No kernel support)” when attempting to use the TCP_NODELAY socket option on Mac OS X/Darwin. Kernel support is there, however the required header file where TCP_NODELAY is defined is not being included. This patch simply alters syshead.h to include <netinet/tcp.h> on Darwin platforms.

"Socket flags: TCP_NODELAY=1 succeeded” when running with debug enabled. In addition the latest beta version of Viscosity is using a copy of OpenVPN with this patch applied: no issues have been reported from testers thus far.
