// Definition of the platform ID.
//
// The platform ID is made up of portions:
// The most significant BYTE is used for identifying the OS platform which the
// client is running and the second most significant BYTE is used for identifying 
// the ISV that has provided the client image.  The last 2 bytes are used by 
// the ISV to specify the build of the client image.
//
// When supplying the platform ID for platform challenge, the client will use
// the logical OR value of the OS and IMAGE identifiers.  For example, a 
// Microsoft win32 build 356 client running on WINNT 4.0 will give the platform 
// value of:
// 
// CLIENT_OS_ID_WINNT_40 | CLIENT_IMAGE_ID_MICROSOFT | 0x00000164
