Local install using XAMPP - fn_classes_initializers.php errors

I am trying to install a local copy of my store to be able to upgrade to newer versions. With my modifications, the normal upgrades do not work.

When I installed the stor locally on a windows xp machine with XAMPP, I get several errors on the index.php page load.

Here are some of the first set of errors:

Deprecated: Assigning the return value of new by reference is deprecated in C:\xampp\htdocs\cscart\core\fn_classes_initializers.php on line 181

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\cscart\core\fn_classes_initializers.php:181) in C:\xampp\htdocs\cscart\core\sessions.php on line 40

Warning: Parameter 1 to array_multisort() expected to be a reference, value given in C:\xampp\htdocs\cscart\core\fn_common.php on line 1933

Any ideas on what is not configured correctly? 1.3.5-SP1 install
