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

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

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

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

613 symbol has a value in the ECOFF symbol but not in the BFD symbol,
614 keep the value in the ECOFF symbol. This helps gas.
616 * linker.c (_bfd_generic_link_output_symbols,
617 _bfd_generic_link_write_global_symbol): Don't require that all
618 references to a common symbol be themselves common symbols.

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

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

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

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

885 read_dynamic_relocs fields.
886 * aout-target.h (MY(backend_data)): Initialize

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