VC++ 6 linker errors when overloading operator new and operator delete

Hello,
I'm coding a MFC application in Visual C++ 6 and I need to overload
operator new and delete for controlling which functions allocs which
resources.
My solution is something in this lines.

// in new_debug.h
#include <new>
struct debug_new_t { };

#define New ::new(__FILE__, __LINE__, *(debug_new_t*)0)
#define DelPointer(_p) ::delete _p
#define DelArray(_p) ::delete[] _p

void* operator new(size_t const, char const*, size_t const,
debug_new_t const&);
void* operator new[](size_t const, char const*, size_t const,
debug_new_t const&);
void operator delete(void*, char const*, size_t const, debug_new_t
const&);
void operator delete[](void*, char const*, size_t const, debug_new_t
const&);

// I've defined the body of the previous functions inside
new_debug.cpp

// in test.cpp
....
int* const ptr = New int();
DelPointer(ptr);
int* const ptr2 = New int[256];
DelArray(ptr2);
....

On compile-time this gives an error:
xlocnum(45) : error C2660: 'delete[]' : function does not take 1
parameters
xlocnum(46) : error C2660: 'delete[]' : function does not take 1
parameters
xlocnum(47) : error C2660: 'delete[]' : function does not take 1
parameters

So I decided to declare "delete[](void*)" function

// at the end of new_debug.h
void operator delete[](void*);

Now more errors:
locale(218) : error C2660: 'new[]' : function does not take 1
parameters
xlocale(218) : error C2660: 'new[]' : function does not take 1
parameters

I tried further and declare "new[](void*)" too

// at the end of new_debug.h
void operator new[](size_t const);

test.obj : error LNK2001: unresolved external symbol "void __cdecl
operator delete[](void *)" (??_V@YAXPAX@Z)
test.obj : error LNK2001: unresolved external symbol "void * __cdecl
operator new[](unsigned int)" (??_U@YAPAXI@Z)

I don't know how to fix this linker errors. Didn't exist predefined
versions of those functions in the CRT for VC6.0?

Thanks in advance
