2012-07-11  Ian Lance Taylor  <iant@google.com>

	* arm.cc (Arm_relocate_functions::abs16): Remove unused typedef.
	(Arm_exidx_cantunwind::do_fixed_endian_write): Likewise.
	(Target_arm::scan_reloc_for_stub): Likewise.
	* common.cc (Symbol_table::do_allocate_commons_list): Likewise.
	* dwarf_reader.cc (Dwarf_die::skip_attributes): Likewise.
	* ehframe.cc (Eh_frame::do_add_ehframe_input_section): Likewise.
	* incremental.cc (Sized_incr_dynobj::do_add_symbols): Likewise.
	* powerpc.cc (Target_powerpc::relocate_tls): Likewise.
