 * On Win32, we map three kinds of error codes:
 * - GetLastError(): for Win32 functions
 * - WSAGetLastError(): for Winsock functions
 * - errno: for standard C library functions
 *
 * We do not check for WSAEINPROGRESS and WSAEINTR because we do not
 * use blocking Winsock 1.1 calls.
 *
 * Except for the 'socket' call, we do not check for WSAEINITIALISED.
 * It is assumed that if Winsock is not initialized, that fact will
 * be detected at the time we create new sockets.
