It seems that somehow the first template argument is not recognized as
template, again. Sometimes it helps to say explicitly that this is a
type identifier by:

 template< std::size_t order, std::size_t dim, typename Data_T >
 WTensor< order, dim, Data_T >::WTensor()
    : WTensorFunc< typename WTensorBase, order, dim, Data_T >()
