I noticed that in 4.0.2 that __FILE__ loses it's value after a file is included.  This is having an impact on a lot of my legacy code that was written before include_once() was added because I use __FILE__ to make a unique variable to mark that a file has been included already.

Here's some code that demonstrates the problem:

<?
	$x++;
	
	if($x > 10)
	{
		return(FALSE);
	}
	
	print("$x: " . __FILE__ . "<br>\n");

	include("testinclude.php");

?>

It's producing:

1: /usr/local/apache/htdocs/testinclude.php
2: 
3: 
4: 
5: 
6: 
7: 
8: 
9: 
10: 

Related to this is that if I switch to include_once, __FILE__ now holds the value of just "testinclude.php".
It loses it's path.

I'm not seeing this behavior in 4.0.1pl2.  I apologize for not having the time to dig into the source right now to figure out what's going on.  Hopefully someone remembers making the change that broke __FILE__.
