stdafx.h中定义

// 设备版

#define WINVER _WIN32_WCE

//Win32版

#ifndef WINVER // Allow use of features specific to Windows XP or later.
#define WINVER 0x0501 // Change this to the appropriate value to target other versions of Windows.
#endif

=================================

WINVER是Windows版本号

Windows Server 2003
WINVER>=0x0502
Windows XP
WINVER>=0x0501
Windows 2000

WINVER>=0x0500
Windows NT 4.0
WINVER>=0x0400
Windows Me
WINVER>=0x0500
Windows 98
WINVER>=0x0410
Windows 95
WINVER>=0x0400

================================

Compiler _MSC_VER value
-------------------- -----------------------
C Compiler version 6.0 600
C/C++ compiler version 7.0 700
Visual C++, Windows, version 1.0 800
Visual C++, 32-bit, version 1.0 800
Visual C++, Windows, version 2.0 900
Visual C++, 32-bit, version 2.x 900
Visual C++, 32-bit, version 4.0 1000
Visual C++, 32-bit, version 5.0 1100
Visual C++, 32-bit, version 6.0 1200
Visual C++, 32-bit, version 2002 1300
Visual C++, 32-bit, version 2003 1310
Visual C++, 32-bit, version 2005 1400
Embedded Visual C++, 32-bit,version 4.0 Cross 1200 - 1202
Visual C++, 32-bit, version 2008 1500

=====================================

3.实例解说
01) 根据_MSC_VER值判断当前的编译环境.
#if _MSC_VER >= 1400
// this is Visual C++ 2005
#elif _MSC_VER >= 1310
// this is Visual c++ .NET 2003
#elif _MSC_VER > 1300
// this is Visual C++ .NET 2002
#endif
02) #else if 和 #elif 的细微差别
#if _MSC_VER < 1202
//EVC 4.0 complier is cross 1200 - 1202
#else if _MSC_VER >= 1400
//Visual C++ 2005 complier is 1400
#else
//Visual C++ 2005 complier is 1400
#endif
这段预编译代码在Evc4.0和visual studio 2005中编译会出错,提示错误为"unexpected #else".此时只要将"#else if"置换成"#elif"即可:
#if _MSC_VER < 1202
//EVC 4.0 complier is cross 1200 - 1202
#elif _MSC_VER >= 1400
//Visual C++ 2005 complier is 1400
#else
//Visual C++ 2005 complier is 1400
#endif
===========================================================

判断当前CPU类型

#ifdef _X86_
//x86
#endif

#ifdef _MIPS_
//Mips
#endif

#ifdef _ARM_
//Arm
