[ns] nse compiling

[Ricciato Fabio <Fabio.Ricciato@TILAB.COM>]

Hi,
I tried to compile nse for emulation support but I received the following
errors

emulate/net-ip.cc: In method `int UDPIPNetwork::recv(unsigned char *, int,
sockaddr &, double &)':
emulate/net-ip.cc:284: `socklen_t' undeclared (first use this function)
emulate/net-ip.cc:284: (Each undeclared identifier is reported only once
emulate/net-ip.cc:284: for each function it appears in.)

emulate/net-ip.cc:885: passing `unsigned char *' as argument 4 of

make: *** [emulate/net-ip.o] Error 1

where can I find the right source code for net-ip.cc ?
Thanks
