 // http://msdn.microsoft.com/en-us/library/ms705945(VS.85).aspx. Windows XP
 // Service Pack 3 (and Windows XP Service Pack 2, if upgraded with a hot fix)
 // also support a limited version of the WLAN API. See
 // http://msdn.microsoft.com/en-us/library/bb204766.aspx. The WLAN API uses
 // wlanapi.h, which is not part of the SDK used by Gears, so is replicated
