We should add internal constructors for accessing these variables.

Today I tried to run PHP-GTK with ZE2 changes against current CVS and it
segfaulted. I traced it to the fact that
PG(http_globals)[TRACK_SERVER_VARS] is no longer available if $_SERVER
is not present in the PHP code, due to the changes Zeev (I think) made
in order to improve efficiency. I don't quite agree with the way it
works right now. My extension needs access to the $_SERVER['argv'] and
$_SERVER['argc'] variables internally, even if the user code doesn't.
How am I supposed to retrieve those variable if they aren't even
registered?

Just out of curiosity (I don't think it's a long term fix) but does 
eval_string()'ing a string with $_SERVER['argv'] solve the problem?

Well, it works well though :)  All you have to do is hint PHP that you're 
going to touch it, and it will be available for you immediately.  To do 
that, simply call:

zend_is_auto_global("_SERVER", sizeof("_SERVER")-1 TSRMLS_CC);

and you're done.  ext/standard/info.c already makes use of this.

Thanks, that worked.
