C++ Sockets

Hi,

I can't compile.
under Seven 64Bits/ Cygwin lastest, no support windows.
(I can compile big lib, Boost, Mysql, Apache etc)
normally no problem on my installation.

I have this error. (Compiler GCC 4.3.4)
compile with "linux-x86-32"

g++ -Wall -g -I/usr/include/libxml2 -MD -D_VERSION='"2.3.9.6"' -O2 -DLINUX -c -o Socket.o Socket.cpp
Socket.cpp: In member function 'bool Socket::IpAddMembership(ip_mreqn&)':

Socket.cpp: In member function 'bool Socket::IpDropMembership(ip_mreqn&)':
Socket.cpp:1282: error: invalid application of 'sizeof' to incomplete type 'ip_mreqn'
make: *** [Socket.o] Error 1

Why not use a public svn/git repository?

The following patch allows it to build with DETACH and RECONNECT unconfigured.

Disabling DETACH or RECONNECT breaks the build in v2.3.9.3:
I turned off both of these in my config-sockets.h file and when I make:

I use this library in my assignment. It is a chatting program, C++ Sockets as low level, QT as GUI, works well.

Just curious how robust is this lib.
I have found another similar library Boost:asio.
What's the advantage and disadvantage of this C++ Sockets.
