Using bitset class inside another

Hi everyone,
I'm working on a Red-Black Binary Tree project that's using (or trying to) the standard bitset class.

When I try to declare a bitset inside a struct that belongs to the RBTree class (or anyother place in the class) i get this message from the compiler (I'm using Dev-C++, newest version, in Windows)
ISO C++ forbids declaration of `bitset' with no type

First I though it was some syntax error, but I ran a code where the bitset isn't inside a class and it worked.
So I looked up for a sample that used bitset inside a class, and I got the same error message.
(this is the sample code)

Anyone knows if this is just a Dev-C++ thing or am I doing something wrong?


My code:

Code:

---

#include <iostream>
#include <exception>
#include <bitset>

#define cor 0
#define corp 1
#define Fdir 2
#define Fesq 3
#define Pdir 4
#define Pesq 5
#define folha 6
#define root 7

#ifndef _RBTree_
#define _RBTree_ 1

class TRBTreeError: public std::exception{
    public:
        TRBTreeError (char *msg){
            printf("[RBTreeError]: %s\n",msg);
        }
};


class TRBTree{
    enum TraversingDir {
        sdInOrder,
        sdPreOrder,
        sdPosOrder,
    };
    typedef struct node{
        void *Data;
        struct node *pRight, *pLeft, *pFather;
        bitset<8> Info;
    } RBNode;
    public:
        TRBTree(int(*fnComp)(void*, void*), void(*getLabel)(void*, char*));
        ~TRBTree();
        TraversingDir getTraversingDir();
        void setTraversingDir(TraversingDir value);
        void Insert(void *data);
        bool Delete(void *data);
        bool Destroy(void *data);
        void *Search(void *data);
        void Last();
        void First();
        void Prior();
        void Next();
        void *getCurrent();
        void DeleteAll();
        void DestroyAll();
        int getCount();
        bool GoToFather();
        bool GoToLeft();
        bool GoToRight();
        bool GoToRoot();
        bool Successor();
        bool Antecessor();
        void WriteGraphvizSource(FILE *f, bool blackwhite = true);
    private:
        void LeftRotate(RBNode *node);
        void RightRotate(RBNode *node);
        RBNode *pRoot, *pCurrent;
        int FCount;
        int (*pFnComp)(void*, void*);
        void (*pFnGetLabel)(void*, char*);
        TraversingDir FTraversingDir;
};

#endif

Bitset is of the namespace "std"

Code:

---

std::bitset<8> test;

---

Try this:

Code:

---

#include <iostream>
#include <bitset>

using namespace std;

class Blah
{
private:
        typedef struct node
        {
                int n;
                bitset<8> Info;
        }RBNode;

        RBNode rbn;
       
public:
        Blah(int num)
        {
                rbn.n = num;
                bitset<8> temp(num);
                rbn.Info = temp;
        }
        void show()
        {
                cout<<rbn.n<<endl;
                cout<<rbn.Info<<endl;
        }
};

int main()
{
        Blah b(10);
        b.show();

        return 0;
}

Worked perfectly

Thanks, really, a lot :D
