I wrote a code thay contain a part like below :

struct Point
{
    double x;
    double y;
    void print();
};

and when I compiled it another file came out. the name of that file isstl_iterator_base_funcs.h,
it has something like these:

#ifndef _STL_ITERATOR_BASE_FUNCS_H
#define _STL_ITERATOR_BASE_FUNCS_H 1

#pragma GCC system_header

#include <bits/concept_check.h>
#include <debug/debug.h>

namespace std _GLIBCXX_VISIBILITY(default)

and it told me there were errors in that code, one is like[Note] 'template<class _InputIterator, class _Distance> void std::__advance(_InputIterator&, _Distance, int)' previously declared here

I use Dev-C++ 5.11, before I compiled the code I write struct within, there were no problems to compile and conduct the program. this is the first time I writestruct, so I am not sure if it’s this causes the problem.
