c++ weird struct and bitset error

Question

I have this inside my private class declarations

#include "stdafx.h"
using namespace std;
    template <typename Key, typename T>
    class A{
    //....
    private:
        static const unsigned int HSIZE = 32;
        struct Bucket {
            Key key;
            T value;
            bitset<HSIZE> jumpMap;
        };
    //....
    };

Gives the following errors:

Error   1   error C4430: missing type specifier - int assumed
Error   2   error C2059: syntax error : '<'
Error   3   error C2238: unexpected token(s) preceding ';'

And when i remove the bitset line, it gives me no errors. What am i doing wrong?

EDIT: Added more relevant lines

Is this the real code? Because I don't see what is `Key`, `T`, `HMAX` - are they defined? — Kiril Kirov, Sep 10 '11 at 18:18
No need to add the full class definition, especially if it's long. Just the things, I'm asking for :) Also, have you included the bitset header and included namespace std? — Kiril Kirov, Sep 10 '11 at 18:21
what you need is templates http://en.wikipedia.org/wiki/Template_%28programming%29 — fazo, Sep 10 '11 at 18:25
Now would you be so gentle to add the template instantiation that is triggering such error? — K-ballo, Sep 10 '11 at 18:26

Have you included the bitset header? I think you have missed it?

jesus wth? i included it on stdfax.h but it doesnt work. But if i include it in the header itself, it works. Can somebody explain why is this? – JavierIEH Sep 10 '11 at 18:31
Why you think, that `stdfax` will include all headers for you :) – Kiril Kirov Sep 10 '11 at 18:34

I thought the idea of stdfax is to include all your headers there, then just include stdfax to have all of them on one call – JavierIEH Sep 10 '11 at 18:46
Yep, I've got it, that's why I posted the link above :) No problems, I'm glad, that I helped :) – Kiril Kirov Sep 10 '11 at 18:51

Should HMAX be HSIZE instead? Otherwise make sure you include < bitset >, and that the name is in scope. You probably have a using namespace std in your code, since you don't qualify it with std::. But my bet goes to HMAX <-> HSIZE.
