Description:
------------
when running php4-cgi via fastcgi using a bash script that
exec's the php4-cgi binary the -d (define) argument is not respected.


Reproduce code:
---------------
-- start script --
exec /usr/bin/php4-cgi -d include_path='.:/tmp/:/usr/share/php'


Expected result:
----------------
include_path to be changed for the php4-cgi process


Actual result:
--------------
include_path not changed, and is still the same as the php.ini file used
-- other tests --
when running the same binary on the commandline (ie not via fastcgi) include_path is changed
when running php5-cgi in above configuration include_path is changed
