>Description:
	If a template contains a static array, and the dimension
        of the array is defined by a const static member with initializer,
        and the dimension is used in the definition of the static array,
	g++ gives an error "conflicting types"; which probably means
	that the value of the dimension is lost.
>How-To-Repeat:
template <class T>
class X
{
  static const int a = 5;

  static T b[a];
};

template <class T> T X<T>::b[X::a];

>Fix:
	The dimension can be left out in the definition of the static member.
