81 "unsigned", some compilers don't like it after "unsigned".
82 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
83 "val" in prototype declaration because some compilers don't like

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

124 bfd_coff_symname_in_debug returns true, don't put symbol name in

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

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

300 (ecoff_compute_section_file_positions): Save the size of the

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

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

422 read_dynamic_relocs fields.
423 * aout-target.h (MY(backend_data)): Initialize

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