I build GetSystemEnv for avs 64
no source change, just make c++ 6.0 project workspace by Microsoft Visual Studio 6.0 in winxp then open it in Visual c++ 2008 in win7 and update and convert project to c++ 2008, and last, open c++ 2008 project file in vs2012 and update the project and build it in x64 with avs 2.5 x64 header
