2002-06-18 H.J. Lu (hjl@gnu.org)

	* nm.c: Include "elf/common.h".
	(extended_symbol_info): Add elfinfo, a pointer to
	elf_symbol_type.
	(SYM_SIZE): Use elfinfo if it is not NULL.
	(get_symbol_type): New function.
	(display_archive): Set print_width for each archive member.
	(display_file): Likewise.
	(display_rel_file): Don't set print_width here.
	(print_object_filename_sysv): Handle print_width.
	(print_archive_member_sysv): Likewise.
	(print_symbols): Pass (bfd_vma) 0 to print_symbol.
	(print_symbol): Set the elfinfo field in extended_symbol_info
	for ELF.
	(print_object_filename_sysv): Fix the output format.
	(print_symbol_info_sysv): Print type and section for ELF.

2002-06-18  Elias Athanasopoulos  <eathan@otenet.gr>

	* nm.c (print_size_symbols): Remove assignment, which makes
	the symbol's size equal to its value when --size-sort is
	used.
