[Dev-C++] undefined reference

[MiGa <MiG...@gm...>]

Hi,
got the following compiler error when trying to compile this:
	WSAIoctl(s, SIO_RCVALL, &val, sizeof(val), NULL, 0, &len, NULL, NULL);

undefined reference to `WSAIoctl@36'. I looked into the FAQ and linked
the -lwsock32 but this error still appears. Any hint?
