答：可使用如下语句判断

//===============
//判断WinCE版本号
#if (_WIN32_WCE == 211)
//Your code;
#endif

#if (_WIN32_WCE >= 200)
//Your code;
#endif

#if (_WIN32_WCE < 300)
//Your code;
#endif

//=============
//判断WinCE与PC
#if defined(_WIN32_WCE)
//Your code;
#endif

//==============
判断Palm Size PC
#if defined(_WIN32_WCE_PSPC)
//Your code;
#endif

//=============
//判断Pocket PC
if defined(WIN32_PLATFORM_PSPC)
// Pocket PC or Palm Size PC
#if (WIN32_PLATFORM_PSPC == 1)
// Pocket PC 2000
#elif (WIN32_PLATFORM_PSPC == 310)
// Pocket PC 2002
#else
// Some other Pocket PC
#endif

//=============
//判断模拟器
#ifdef _WIN32_WCE_EMULATION
//Your code;
#endif

//=============
//判断HPC
