Description:
------------
I am using apc_load_constants() and apc_define_constants() within CLI code. It appears that these functions behave differently in the CLI SAPI than they do in the Apache 2 SAPI, in that apc_load_constants() throws notices about constants already being defined. This does not occur in the Apache 2 SAPI.

Reproduce code:
---------------
<?php
if( ! apc_load_constants( 'general' ) ) {

	$constants = array(
		'HTTP_OK' =>		200,
		'HTTP_CREATED' =>	201,
		'HTTP_ACCEPTED' =>	202,
	);

	apc_define_constants( 'general', $constants );
	apc_load_constants( 'general' );

}
?>

Expected result:
----------------
The constants get defined and cached (this is what happens under Apache 2).

Actual result:
--------------
Notice: Constant HTTP_OK already defined in ...
Notice: Constant HTTP_CREATED already defined in ...
Notice: Constant HTTP_ACCEPTED already defined in ...

These errors refer to the second apc_load_constants() line, last function call in the snippet above.
