note 80110 added to function.delete

I have founda that trying to delete a file using relative path like the example below does not work.

	$do = unlink("../pics/$fileToDel");
	if($do=="1"){
	    echo "The file was deleted successfully.";
	} else { echo "There was an error trying to delete the file."; } 

I did not work at all, instead what I had to do was: 

	chdir('../pics/');
	$do = unlink($fileToDel);
	if($do=="1"){
	    echo "The file was deleted successfully.";
	} else { echo "There was an error trying to delete the file."; }

Then it worked !
