How is it that this

template<int size, bool big_endian>
class Target_powerpc : public Sized_target<size, big_endian>
{
 public:
  typedef
    Output_data_reloc<elfcpp::SHT_RELA, true, size, big_endian> Reloc_section;
  typedef typename elfcpp::Elf_types<size>::Elf_Addr Address;
  typedef typename elfcpp::Elf_types<size>::Elf_Swxword Signed_address;
  static const Address invalid_address = static_cast<Address>(0) - 1;

gives no errors about "invalid_address" being undefined, while this

template<int size, bool big_endian>
class Stub_table : public Output_relaxed_input_section
{
 public:
  typedef typename elfcpp::Elf_types<size>::Elf_Addr Address;
  static const Address invalid_address = static_cast<Address>(0) - 1;

does?  As far as I can see, all of the references to
Stub_table::invalid_address occur after the class definition.
I see I also have a complaint about Output_data_glink::pltresolve_size.
