Linking error LNK2005 with * __cdecl

Ilya81 (2)
I'm writing a program of array processing, but I've got a linking error and can't compile it. The message is
error LNK2005: "void * __cdecl operator new(unsigned int)" (??2@YAPAXI@Z) already defined in LIBCMTD.lib(new.obj)

The program uses no classes exepting the Form1, I've removed all the others. But the error still presents. The asteric is used for multiplication, for array paramters and for files using by fopen etc. functions. The types are only int, double and bool, and there is a FILE handle. One additional unit provides only some functions and has only
1

#include "StdAfx.h"
#include <math.h>

in impelemetation. I've tryed to comment various sections but the error doesn't disappear. Tell me please how can I cope with such linking error.

You're redefining a method that already exists in some static library. Post the code and I might be able to tell you what's causing it.

As I could guess about possbile redefinings may be it can be #include "StdAfx.h" and #include "afxdlgs.h". But both modules don't work without it. So how to define it to make the project linkable.
