>Description:
Pointer to member template constants are not properly resolved.  The compiler returns:

template.cpp:18: type/value mismatch at argument 2 in template parameter list for `template<_T, int _T::*<anonymous> > struct Number'
template.cpp:18:   expected a constant of type `int _T::*', got `int _T::*'
template.cpp:19: ISO C++ forbids declaration of `parameter' with no type
template.cpp: In function `int main()':
template.cpp:27: no matching function for call to `foo(Number<Type, &Type::i>)'
