Can't use php-soap in windows enviroment?

First of all, I'd like to thanks everybody in advance. Actually I've got a winlamp distribution of php 5 in a web server. My need is to use the php-soap functions to implement soap webservices (server) but in php-soap specification is shown I need php configured with -enable-soap to use any php-soap function. Im'not expert in configuring php, but at first glance I believe that modify php configuration adding --enable-soap can only be done recompiling php, isn't it? So, how can I overcome this kind of problem?
