C语言头文件是不是有问题

    while (1) {
        Render();
        Sleep(sp);

        DeleteObject(hbitmap);
    }
}

    ShowWindow(hWnd, nC);
    UpdateWindow(hWnd);
    tDC = GetDC(hWnd);
    cDC = CreateCompatibleDC(tDC);
    MSG M;
    bgra = calloc(4, (unsigned long long)1920 * 1080);
    CreateThread(0,0,WRender,0,0,0);
    while (GetMessage(&M, 0, 0, 0)) {
        if (M.message == WM_SIZE) {
            RECT Rect;
            GetWindowRect(hWnd,&Rect);
            MoveWindow(hWnd, Rect.left, Rect.top, Rect.right - Rect.left, (Rect.right - Rect.left) / 16 * 9, 1);
        }
    }
    return 0;
}

如上，一个简单的窗口，我用VS编译提示HWND找不到，用GCC编译提示WinUser.h存在语法错误，TCC编译则是提示WinUser.h其中一条typedef没加分号。上述三个编译器的头文件我没动过，VS还是今天才安装的，请问怎回事啊？

用vc编译试试
