	* dwarf2.c (comp_unit): Move it earlier in the source. Add
	addr_size.
	(read_address): Replace 'bdf*' argument with 'comp_unit*' argument.
        Use addr_size for address size, rather than sizeof(bfd_vma).
	(read_attribute): Replace bdf* argument with 'comp_unit*' argument.
	Fix call to read_address.
	(decode_line_info): Replace bdf* argument with 'comp_unit*' argument.
	Scrap other unneeded arguments.  Fix call to read_address.
	(scan_unit_for_functions): Fix call to read_attribute.
	(parse_comp_unit): We now handle more values for addr_size.
	Set addr_size in unit.  Fix call to read_attribute and
	decode_line_info.
