572 * srec.c (srec_write_record): Put CONST keyword for "src" before
573 "unsigned", some compilers don't like it after "unsigned".
574 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
575 "val" in prototype declaration because some compilers don't like
576 arguments whose names are the same as types.

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

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

618 debug_string_size is not 0, check that it matches the size of the

642 symbol has a value in the ECOFF symbol but not in the BFD symbol,
643 keep the value in the ECOFF symbol. This helps gas.
645 * linker.c (_bfd_generic_link_output_symbols,
646 _bfd_generic_link_write_global_symbol): Don't require that all
647 references to a common symbol be themselves common symbols.

691 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
692 (only testing for m68k and vax at the moment); do verify that the
693 preprocessor didn't trash the arch name inside the string version.

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

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

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

862 The sparc (and possibly other?) NLM format requires a different
863 way to write exports, so add a write_export field to the backend
864 data (and set it to NULL for everything but the sparc).
866 Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
868 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,

914 read_dynamic_relocs fields.
915 * aout-target.h (MY(backend_data)): Initialize

926 * config/alphaosf.mh (HDEFINES): Don't define HOST_64_BIT here;
