Wrong value for WC_DIALOG

[steward-fu]

Here is the code about to create window

Method MyApp.Init, uses esi
    SetObject esi
    invoke CreateWindowEx, WS_EX_LEFT, WC_DIALOG, $OfsCStr("main"), 
        WS_OVERLAPPEDWINDOW or WS_VISIBLE, 0, 0, 300, 300, NULL, NULL, NULL, pSelf
    m2m [esi].hWnd, eax
MethodEnd

ObjAsm/Code/Inc/Windows/winuser.inc

WC_DIALOG equ (MAKEINTATOM(8002h))

ObjAsm/Code/Inc/Windows/winbase.inc

MAKEINTATOM macro i
  exitm <(LPTSTR) (((i)))>
endm 

But the value becomes as 8006h (the original one is 8002h) after compiling.
For workaround, I set as the following:

WC_DIALOG equ 8002h

Could please help fix this issue ?
