The missing #include <netinet/tcp.h> causes a defined(TCP_NODELAY) to
fail.  I have added the patch to the FreeBSD ports OpenVPN 2.2.2 and
2.3.0, and confirmed (with strings ... | grep) that the TCP_NODELAY code
is now part of the executable on amd64, and results in this log output:

Sat Jan 12 13:39:18 2013 Listening for incoming TCP connection on [undef]
Sat Jan 12 13:39:18 2013 Socket flags: TCP_NODELAY=1 succeeded
