+
+       Extend pdp11-aout symbol table format to accommodate .stab
+       symbols and implement correct handling of them.
+
+       * pdp11.c (pdp11_external_nlist): Repurposed e_unused to e_desc.
+       (N_STAB, is_stab): Needed new function is_stab to disambiguate
+       normal vs. .stab symbol table type values, replacing N_STAB mask.
+       (translate_from_native_sym_flags): Determine correct section for
+       different .stab types.
+       (translate_to_native_sym_flags): Leave .stab types intact.
+       (translate_symbol_table): Error if symbol indicates overlay;
+       store desc field from .stab symbols.
+       (write_syms): Output desc field with symbol.
+       (aout_link_check_ar_symbols): Skip .stab symbols.
+       (aout_link_add_symbols): Correctly distinguish .stab symbols.
+       (aout_link_write_other_symbol): Write 0 for desk and ovly fields.
+       (aout_link_write_symbols): Write 0 for desk and ovly fields;
+       correctly distinguish .stab symbols and select calculate their
+       section and value; and copy desc and ovly fields from input symbol
+       to output symbol.
