Hi, As i ecperienced the Yahoo! and the msn handle this under different domains. If You have a google webmaster account You can specify the prefered domain. E.G. You want Your site listed under http://sitename.com After You've chosen this prefered domain, google will follow the links pointing to the http://www.sitename.com site as if they were pointing to the http://sitename.com
A recommended tip for this is to do a 301 redirect from one to the other. For example, if you decide that www.sitename.com is your preference, then do a 301 from sitename.com to www.sitename.com. This avoids any page rank diffusion due to canonical issues.
