// Filename: Processor.cpp
// =======================
// Author: Benjamin Jurke
// File history: 27.02.2002  - File created. Support for Intel and AMD processors
//               05.03.2002  - Fixed the CPUID bug: On Pre-Pentium CPUs the CPUID
//                             command is not available
//                           - The CProcessor::WriteInfoTextFile function do not 
//                             longer use Win32 file functions (-> os independend)
//                           - Optional include of the windows.h header which is
//                             still need for CProcessor::GetCPUFrequency.
//               06.03.2002  - My birthday (18th :-))
//                           - Replaced the '\r\n' line endings in function 
//                             CProcessor::CPUInfoToText by '\n'
//                           - Replaced unsigned __int64 by signed __int64 for
//                             solving some compiler conversion problems
//                           - Fixed a bug at family=6, model=6 (Celeron -> P2)
