WinCE + Lnk2019 + WinSocket

Hej!

Jeg har følgende mærkelige fejl, hvorfor får jeg dem i denne kode

#include <Winsock2.h>
#include <WS2TCPIP.H>

error LNK2019: unresolved external symbol getaddrinfo referenced in function "struct addrinfo * __cdecl TCPIP_ResolveAddress(char *,char *,int,int,int)" (?TCPIP_ResolveAddress@@YAPAUaddrinfo@@PAD0HHH@Z)


----------------------------------------------------------------
struct addrinfo* TCPIP_ResolveAddress( CHAR *addr, CHAR *port, int af, int type, int proto ){
    struct addrinfo hints, *aiResolved = NULL;
    int rc;
    ZeroMemory( &hints, sizeof( hints ) );
    hints.ai_flags = ((addr)?0:AI_PASSIVE );
    hints.ai_family = af;
