Compiling for ACAD 2004

We can crossing our apllication to support Autodesk2004 and we have still error in the include process. We have this error in file ATLCORE.H : d:\Programme\Vc7\atlmfc\include\atlcore.h(52): error C2447: '{' : Funktionskopf fehlt - Parameterliste im alten Stil?

#include <crtdbg.h>

I trought close this bracket, disable this bracket, make new bracket, add code in to, but neither of this variant were well.
