Answer 1

You've defined your new macro before your functions. Your code ends up looking like:

void *
  operator new(__FILE__, __LINE__)(unsigned int size, const char *file, int line)

Which is obviously wrong. Your should move the macro definitions underneath the functions (or better is to keep those functions in a .cpp file you link with.) For what it's worth, new is a keyword and cannot be an identifier, so your program is, strictly speaking, ill-formed.

I recently posted my global memory operators framework. It might help you a bit.

Answer 2

the signature don't match it sould be void* operator new (size_t size).

overriding single object new signature is static void * operator new(site_t size),
