static data member problem

[Mark E.]

The program below generates an "undefined reference to 
container<char>::null_str_c" when STATIC is defined with egcs 
1.1 for DJGPP. It seems perfectly legal to me, is the error correct 
or have I found a bug?

#define STATIC

template <class charT>
class container
{
public:
    typedef charT value_type;
#ifdef STATIC
    static
#endif
    value_type null_str_c;
    const value_type* data() ;
};


template <class charT>
inline
const container<charT>::value_type *
container<charT>::
data ()
{
  return &null_str_c;
}


#ifdef STATIC
template<class charT>
container<charT>::value_type
container<charT>::
null_str_c = static_cast<value_type>(0);
#endif

typedef  container<char> cstring;

int main()
{
  cstring v;
  v.data();
  return 0;
}
