Description:
------------
When testing if a variable variable, which is not set, is set the
result is different between 4.x and 5.x.
PHP 5.x should behave as PHP 4.x.
We didn't find any bug related to this description.
Best regards.

Reproduce code:
---------------
unset($var_tmp);
$var = "var_tmp";
if(isset($$var))
	echo "var_tmp is set.";
else
	echo "var_tmp is not set.";

Expected result:
----------------
var_tmp is not set.

Actual result:
--------------
var_tmp is set.
