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

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

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

710 (only testing for m68k and vax at the moment); do verify that the

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

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

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

932 read_dynamic_relocs fields.

1048 sym_filepos as well.
1049 (ecoff_get_extr): Use ifdmap instead of ifdbase.

1115 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
