STL with gcc3

[Ji Li]

Hello,

	I am experiencing some problem with STL when compile with gcc3. I
have a little piece of c++ code like this:

	#include <iostream>
	#include <string>

	int main(){
	string aa = "Hello World !";

	cerr << aa << endl;
	}

	If I compile it with gcc-2.96, there is no problem. However, when
I compile it with gcc-3.0.4, the compiler does not recognize neither
'string' nor 'cerr'. But if I add 'using namespace std;', gcc-3.0.4 works
fine with it.

	I believe there must be a way to make gcc-3.0.4 backward
compatable but just could find it. Would you please point the way for me?
Thanks a lot.

Regards.
