Statically linked DLL build by VC++ 8.0 still depends on VC++ runtime

I have build a InProc COM DLL via DLL, it is statically linked with ATL and C++ runtime, depends.exe also reported that it does not depends on VC++ dlls, but its manifest file still referred to VC++ 8.0 CRT and I have to copy some VC++ 8.0 redistributes to target machine in order to use it. I have defined #define _WIN32_WINNT 0x0500 in stdafx.h. For an application build by VC++ 8.0 with  _WIN32_WINNT defined, I don’t need to redistribute VC++ 8.0 files.
