that's done:
#ifdef WIN32
#include <winsock2.h>
#include <io.h>
#else

... going to gnubg.c later.
still trying to get external.c compiled

that's done

setsockopt in winsock[2].h looks like:

SOCKET PASCAL accept(SOCKET,struct sockaddr*,int*);
int PASCAL bind(SOCKET,const struct sockaddr*,int);
int PASCAL closesocket(SOCKET);
int PASCAL connect(SOCKET,const struct sockaddr*,int);
int PASCAL ioctlsocket(SOCKET,long,u_long *);
int PASCAL getpeername(SOCKET,struct sockaddr*,int*);
int PASCAL getsockname(SOCKET,struct sockaddr*,int*);
int PASCAL getsockopt(SOCKET,int,int,char*,int*);
unsigned long PASCAL inet_addr(const char*);
DECLARE_STDCALL_P(char *) inet_ntoa(struct in_addr);
int PASCAL listen(SOCKET,int);
int PASCAL recv(SOCKET,char*,int,int);
int PASCAL recvfrom(SOCKET,char*,int,int,struct sockaddr*,int*);
int PASCAL send(SOCKET,const char*,int,int);
int PASCAL sendto(SOCKET,const char*,int,int,const struct sockaddr*,int);
int PASCAL setsockopt(SOCKET,int,int,const char*,int);
int PASCAL shutdown(SOCKET,int);
SOCKET PASCAL socket(int,int,int);

and no SIGPIPE in signal.h (mingw 2)   :-(
