Bug description: Filesize of downloaded file larger then the original file size

Description:
------------
while downloading a file with the header function, the size of the
downloaded file is between 100 and 1000 bytes larger, than the original
file on the server.
PHP version is 4.3.3 and Webserver is IIS 5.0 (OS: WinXP). The same
problem occured with PHP 4.3.2 on an Apache 1.3.28 and was fixed by
updating PHP to version 4.3.3

There are no blank lines after the last line and there are no include
files or auto_prepend files.

Reproduce code:
---------------
<?PHP
$name="E:/ftpx/test/20031013_standards_proe.tgz";
$save_as_name = basename($name);

header("Cache-control: private");
header("Content-Type: application/octet-stream");
header("Content-Disposition: filename=$save_as_name");
header("Content-Transfer-Encoding: binary");
header("Content-length: " . filesize($name));
header("Pragma: public");
echo readfile($name);
?>

Expected result:
----------------
the original size is 158.994.464 Bytes, the downloaded file has
158.994.600 Bytes.
