win32 client receive data function 'socket_read_blob()' (declared in "http.c") call 'recv()' and test return value is negative or else. but if peer unexpected shutdown 'recv()' returns zero. so this functon enters infinite-loop. to fix it, return value is negative or equal to zero as error.

  while ( i<nToRead ){
      read = recv(pSockId, rbuf, 50, 0);
      i += read;
-     if( read<0 ){
+     if( read<=0 ){
        return 0;
      }
      blob_append(pBlob, rbuf, read);
  }

Thank you for fix problems

By the way, on many OSes, recv(2) (or read(2)) returns zero if peer unexpected or expected shutdown is normal behavior. It meanings no more data or end of stream. This behavior is not win32 quirks.
