// 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)
