[Computer-go] Pachi on cygwin

[Don Dailey]

I think you need to set up the stdin and stdout file handles to flush
automatically.

I think this code does that for gcc,

  setvbuf(stdout, NULL, _IONBF, 0 );
  setvbuf(stdin, NULL,  _IONBF, 0 );

or maybe just

  setbuf(stdout, NULL);
  setbuf(stdin, NULL);

If you set this up correctly you do not need to flush after every print of
a line,  i.e.  fflush(stdout);
