* aoutx.h (translate_from_native_sym_flags): Don't try to stuff
pointers into value field for warning and indirect symbols; just leave the value field alone. * linker.c (generic_link_add_symbol_list): Use next symbol for warning and indirect symbols, rather than looking in symbol value. * ecoff.c (ecoff_set_symbol_info): Remove indirect_ptr_ptr parameter. Change all callers. Remove support for indirect symbols; it didn't work anyhow. (_bfd_ecoff_slurp_symbol_table): Remove indirect_ptr variable. * syms.c: Change comments about BSF_WARNING and BSF_INDIRECT. * bfd-in2.h: Rebuild.
