[Dev-C++] std streams and enum?

[Maya <Esc...@ne...>]

Can someone please help me?
I am using an enum type that I want to store in a std::IOStream object, 
but the compiler [complainer] tells me that the format is not supported. 
enum types are the same as 'const int' right? So, there should not be a 
problem!

namespace jme{
enum account_t {Zero, One, Two};
class Account{
protected:
    account_t type;

    ....
public:
    friend std::istream&
       jme::operator>>(std::istream& is, jme::Account& obj){
           is >> obj.type;  // <<======== Here is the problem ****
           return is;
       }
};
}
This gives me an error that reads:
====================================================
account.H: In function `std::istream& jme::operator>>(std::istream&,
    jme::Account&)':
account.H:91: no match for `std::basic_istream<char, 
std::char_traits<char> >&
    >> jme::account_t&' operator <<<<<<<====== This is the problem *****
...: candidates are:

/* Gives me a list of other candidates */

====================================================

Thanks in advance
