如何判断系统是98，还是 me/nt/2000/xp？

[Libran]

用API函数GetVersion()，根据返回值判断：
Platform High-order bit Next 7 bits Low-order byte
Windows NT 3.51 0 Build number 3
Windows NT 4.0 0 Build number 4
Windows 2000 or Windows XP 0 Build number 5
Windows 95, Windows 98, or Windows Me 1 Reserved 4
Win32s with Windows 3.1 1 Build number 3

例子：
dwVersion = GetVersion();
// Get the Windows version.
dwWindowsMajorVersion = (DWORD)(LOBYTE(LOWORD(dwVersion)));
dwWindowsMinorVersion = (DWORD)(HIBYTE(LOWORD(dwVersion)));
// Get the build number.
if (dwVersion < 0x80000000) // Windows NT/2000/XP
dwBuild = (DWORD)(HIWORD(dwVersion));
else if (dwWindowsMajorVersion < 4) // Win32s
dwBuild = (DWORD)(HIWORD(dwVersion) & ~0x8000);
else // Windows 95/98/Me
dwBuild = 0;
