安装DXSOCK V2.0,出现下列错误,如何改？(50分)

如果选忽略,虽能安装,但不能编译例子.
[Warning] DXLPDServerCore.pas(316): Variable ''Queue'' might not have been initialized
[Warning] Unit ''DXCachedIMSLogging'' implicitly imported into package ''DXSockD5''
[Warning] Unit ''DXCachedWEBSITELogging'' implicitly imported into package ''DXSockD5''
[Warning] Unit ''DXCachedW3SVCv30Logging'' implicitly imported into package ''DXSockD5''
[Warning] Unit ''DXCachedNCSALogging'' implicitly imported into package ''DXSockD5''
[Warning] Unit ''DXCachedDebugLogging'' implicitly imported into package ''DXSockD5''
...

ignore
能安装就ok

可是编译samples目录下的例子chat时提示错误:
[Warning] DXSocket.pas(177): Constant expression violates subrange bounds
[Error] DXSocket.pas(279): Undeclared identifier: 'Linger'
[Error] DXSocket.pas(284): Missing operator or semicolon
