// Function:	int TestVersion(void)										//
//																			//
// Parameters:	None														//
//																			//
// Return:		0 indicates a failure - the processor does not match the    //
//				  version the software was built for                        //
//				1 indicates a pass - the processor and software versions    //
//				  both match                                                //
//																			//
// Description:	This function compares the version of the processor being   //
//              run on with the version that the software was built against //
//                                                                          //
// Purpose:		The reason for this test is because the build tools work-   //
//              around various silicon anomalies, by not checking to see    //
//              if the software is built for this particular processor      //
//              version, a risk that an anomaly will not be worked around   //
//              correctly.
