I think that is not correct.

            hWnd = CreateWindow ("STATIC", "", WS_POPUP, 0, 0, 0, 0,NULL,NULL,NULL,NULL);
            ShowWindow (hWnd, SW_HIDE);
        wpOrigProc = (WNDPROC) SetWindowLong(hWnd, GWL_WNDPROC, (LONG) pg_WinProc);

LRESULT APIENTRY pg_WinProc(
    HWND hwnd,
    UINT uMsg,
    WPARAM wParam,
    LPARAM lParam)
{
    MSG rMsg;

    rMsg.message = uMsg;
    rMsg.wParam = wParam;
    rMsg.lParam = lParam;

        // printf ("got message %d\n", rMsg.message);
    switch (rMsg.message)
    {
        case PG_SIGNAL_KILL:
    ......
}
