If I release a "DLL version(not LIB)" of MFC app(such /D "NDEBUG" /D "_AFXDLL" /MD options), is it still run on every win9x platforms. Because it is smaller. And as I saw, it requires adding MFC42loc.dll, MFC42.dll for MFC specific. And I suppose those DLLs are exist on every win98 systems. Is it can be a problem?
