Ambiguity between 'Rect' and '_fastcall Classes:Rect(int,int,int,int)'解决办法

Ambiguity between 'Rect' and '_fastcall Classes::Rect(int,int,int,int)'
BCB6.0 中编译出现：Ambiguity between 'Rect' and '_fastcall Classes::Rect(int,int,int,int)'；
代码如下：
  RECT rect=Rect(20,20,220,80);
  this->Canvas->Rectangle(20,20,220,80);
  DrawText(this->Canvas->Handle,"An example of DrawText.",1,&rect,DT_END_ELLIPSIS|DT_MODIFYSTRING);

怎么办啊。

[解决办法]
RECT rect=Rect(20,20,220,80);
换成：
RECT rect= { 20, 20, 220, 80 };

或者直接用TRect也行。
