Description:
------------
under Windows 2000 Pro DOS mode
I use c:\php\php.exe -f c:\php\test.php
to 'echo' one word for every second
but nothing shown until the end of the execution

I tested it in PHP 4.3.4 & 4.2.3 (Windows version)

however, it works fine in PHP 4.1.2 (Windows version)

ps: I didn't use any output control function

Reproduce code:
---------------
<?php
  //I didn't use output control like ob_start()
  //in PHP 4.3.4 & 4.2.3, I can't see each line for every second (doesn't happen in PHP 4.1.2)
  for($i=0;$i<5;$i++)
  {
    echo $i."\n";
    flush();  //doesn't make any difference with or without this line
    sleep(1);
  }
  //all outputs are shown together at the end of the execution
?>

Expected result:
----------------
it is expected to see each word every one second

Actual result:
--------------
nothing shown during the execution
all results are shown together at the end of the execution
