Is this usage now deprecated?

Global Const $WM_NCHITTEST = 0x0084
Global Const $HTCAPTION = 2, $HTCLIENT = 1
$hGui = GUICreate("Test", 300, 200, -1, -1)
GUIRegisterMsg($WM_NCHITTEST, "WM_NCHITTEST")
GUISetState()

Do

$msg = GUIGetMsg()

Until $msg = -3

Func WM_NCHITTEST($hWnd, $Msg, $wParam, $lParam)

If $hWnd = $hGUI And $Msg = $WM_NCHITTEST Then

Local $iProc = DllCall("user32.dll", "int", "DefWindowProc", _
"hwnd", $hWnd, "int", $Msg, "int", $wParam, "int", $lParam)
If @error Then Return SetError(@error, 0, 0)
$iProc = $iProc[0]
If $iProc = $HTCLIENT Then

Return $HTCAPTION

Else

Return $iProc

EndIf

EndIf

Return 'GUI_RUNDEFMSG'

EndFunc

; or
;Func WM_NCHITTEST($hWnd, $iMsg, $iwParam, $ilParam)

;If ($hWnd = $hGUI) And ($iMsg = $WM_NCHITTEST) Then Return $HTCAPTION

;EndFunc ;==>WM_NCHITTEST

Assuming that GUIRegisterMsg()'s return value is as broken as I think it is, then yes.
