Description:
------------
When extended info is enabled (to generate EXT_* opcodes for debuggers), the namespace decl. on the first line check is not correct (zend_compile.c:5049)

Reproduce code:
---------------
Just any file with a namespace decl, for example: Zend/tests/ns_010.php

Run as:
php -n -e /home/derick/dev/php/php-6.0dev/Zend/tests/ns_010.php

Expected result:
----------------
class ok
class ok
class ok
class ok
method ok
method ok
method ok
method ok
const ok
const ok
const ok
const ok
var ok
var ok
var ok
var ok


Actual result:
--------------
Fatal error: Namespace declaration statement has to be the very first statement in the script in /home/derick/dev/php/php-6.0dev/Zend/tests/ns_010.php on line 2
