编译中遇到问题

[yap111]

我现在用DEV-C++写些简单程序，但是编译时总遇到这样的结果，请问这是什么意思啊
cc1plus.exe D:\自学\vc\cc1plus.exe unrecognized command line option "-fsave-memoized"

把make.conf中的CXXFLAGS+= -fmemoize-lookups -fsave-memoized行注释掉试试

我的简单测试程序：
#include<iostream.h>
main()
{ int a;
cin>>a;
cout<<a;
getchar();
getchar();
}
编译时警告，我不知还要在哪设置什么，把我气死了，请高手们指点
#warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <iostream> instead of the deprecated header <iostream.h>. To disable this warning use -Wnodeprecated.

用什么编译器
要是用DEV-C++的话
#include<iostream.h>
改成
#include <iostream>
using namespace std;
VC的话，不加也没关系~
