#include <winsock2.h> on Windows.
MinGW complained about it not being included.
commit c0af4c37d2046ffb3e07dd62f266a4fb99ea5614

Small fixes in proxy code.
commit 42a8158b1dca6ee4ec1707176199cc36c26da7af
Author: Michael Tokarev <mjt@tls.msk.ru>
Date: Fri May 4 16:41:47 2012 +0400
add (errnum) in front of windows error messages
On localized, non-English versions of windows, it is
common to have two active charsets -- for console applications
and for GUI applications, together with localized error messages
returned by windows. But two charsets are rarely compatible,
so sending the same byte sequence to console and to windows
event log makes one or another to be unreadable. So at least
include the error number, this way it will be possible to
lookup the actual error test using external ways.

commit 5c0dd104f94519c3cb50e9ca44227656c5adc7ae
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Thu Apr 19 15:56:08 2012 +0200
Document new proxy types.
commit 5ae19cb0bb8dd6be1e9bcd560bb051f496a373ec
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Thu Apr 19 15:18:31 2012 +0200
Add support for proxying through an external command.
Proxy type "exec" can be used to have an external script or binary set
up an outgoing connection. Standard input and output will be used to
exchange data with the external command. The variables REMOTEADDRESS and
REMOTEPORT are set to the intended destination address and port.
commit fb5588856fa4dd6f140c72f7360302fe85b20c75
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Thu Apr 19 14:10:54 2012 +0200
Add support for SOCKS 5 proxies.
This only covers outgoing TCP connections, and supports only
username/password authentication or no authentication.
commit b58d95eb29662bce4388f95dbc5762b9e2999806
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Wed Apr 18 23:19:40 2012 +0200
Add basic support for SOCKS 4 and HTTP CONNECT proxies.
When the Proxy option is used, outgoing connections will be made via the
specified proxy. There is no support for authentication methods or for having
the proxy forward incoming connections, and there is no attempt to proxy UDP.
commit 84531fb6e621959e06519fdbb7f2a8f7578f66bd
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Mon Apr 16 01:57:25 2012 +0200
Allow broadcast packets to be sent directly instead of via the MST.
When the "Broadcast = direct" option is used, broadcast packets are not sent
and forwarded via the Minimum Spanning Tree to all nodes, but are sent directly
to all nodes that can be reached in one hop.
One use for this is to allow running ad-hoc routing protocols, such as OLSR, on
top of tinc.
commit 535a55100bb77f107c85361e9f72a194e92bc8bc
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Thu Mar 29 16:45:25 2012 +0100
Allow environment variables to be used for Name.
When the Name starts with a $, the rest will be interpreted as the name of an
environment variable containing the real Name. When Name is $HOST, but this
environment variable does not exist, gethostname() will be used to set the
Name. In both cases, illegal characters will be converted to underscores.
commit 89f4574e0b1553c8e5dcbfc275e829a759b697f6
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Mon Mar 26 14:46:09 2012 +0100
Add support for systemd style socket activation.
If the LISTEN_FDS environment variable is set and tinc is run in the
foreground, tinc will use filedescriptors 3 to 3 + LISTEN_FDS for its listening
TCP sockets. For now, tinc will create matching listening UDP sockets itself.
There is no dependency on systemd or on libsystemd-daemon.
commit cc6aee784659bfbd21eb8d414e00a8f1a801cac4
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Mon Mar 26 14:45:20 2012 +0100
Remove newline from log message.
commit 16e6769feef21a5bf58f6022d990452987bb5efb
Author: Anthony G. Basile <basile@opensource.dyc.edu>
Date: Mon Mar 26 06:29:40 2012 -0400
configure.in: fix AC_ARG_ENABLE and AC_ARG_WITH
The current configure.in file does not correctly make use of these
macros. The resulting configure file will therefore enable an item
even if --disable-FEATURE is given. This patch restores the intended
behavior.

@cindex Broadcast @cindex Broadcast
@item Broadcast = <yes | no> (yes) [experimental] @item Broadcast = <no | mst | direct> (mst) [experimental]
When disabled, tinc will drop all broadcast and multicast packets, in both router and switch mode. This option selects the way broadcast packets are sent to other daemons.
@emph{NOTE: all nodes in a VPN must use the same Broadcast mode, otherwise routing loops can form.}
@table @asis
@item no
Broadcast packets are never sent to other nodes.
@item mst
Broadcast packets are sent and forwarded via the VPN's Minimum Spanning Tree.
This ensures broadcast packets reach all nodes.
@item direct
Broadcast packets are sent directly to all nodes that can be reached directly.
Broadcast packets received from other nodes are never forwarded.
If the IndirectData option is also set, broadcast packets will only be sent to nodes which we have a meta connection to.

The following proxy types are currently supported:

@cindex socks5
@item socks4 <@var{address}> <@var{port}> [<@var{username}> <@var{password}>]
Connect to the proxy using the SOCKS version 5 protocol.
If a @var{username} and @var{password} are given, basic username/password authentication will be used,
otherwise no authentication will be used.
@cindex http
