151 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

186 (coff_write_symbols): Initialize debug_string_size to 0. If
187 bfd_coff_symname_in_debug returns true, don't put symbol name in

212 * ecofflink.c (bfd_ecoff_debug_externals): If a small undefined
213 symbol has a value in the ECOFF symbol but not in the BFD symbol,
214 keep the value in the ECOFF symbol. This helps gas.
216 * linker.c (_bfd_generic_link_output_symbols,
217 _bfd_generic_link_write_global_symbol): Don't require that all
218 references to a common symbol be themselves common symbols.

263 (only testing for m68k and vax at the moment); do verify that the
264 preprocessor didn't trash the arch name inside the string version.

295 bfd_som_set_subsection_attributes): Change parameters from char
296 to int. Following a prototype with an old-style function definition
297 in the presence of widened parameters is a GCC-ism not supported

380 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
381 get the index of a common section, rather than always using

406 undefined, look it up in the linker hash table.
408 * aoutx.h (translate_symbol_table): The string index 0 has a
409 special meaning for normal symbols, but not for dynamic symbols.

433 The sparc (and possibly other?) NLM format requires a different
434 way to write exports, so add a write_export field to the backend
435 data (and set it to NULL for everything but the sparc).

439 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,
