E2010 Incompatible types: ‘Cardinal’ and ‘TSearchRec’

在编写一个非常简单的Delphi程序时，遇到一个奇怪的问题

[DCC Error] Project2.dpr(25): E2010 Incompatible types: ‘Cardinal’ and ‘TSearchRec’

var
  searchResult : TSearchRec;

begin
  // Try to find regular files matching Unit1.d* in the current dir
  if FindFirst('Unit1.d*', faAnyFile, searchResult) = 0 then
  begin
    repeat
      ShowMessage('File name = '+searchResult.Name);
      ShowMessage('File size = '+IntToStr(searchResult.Size));
    until FindNext(searchResult) <> 0;

    // Must free up resources used by these successful finds
    FindClose(searchResult);
  end;
end;

上述代码来自【参考1】

错误始终指向 FindClose(searchResult); 这一句，百思不得其解，后来搜索到了一个解释【参考2】，调换 uses 中的 windows和 sysutils 位置即解决……
