40 "unsigned", some compilers don't like it after "unsigned".
41 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
42 "val" in prototype declaration because some compilers don't like
43 arguments whose names are the same as types.

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

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

191 bfd_som_set_subsection_attributes): Change parameters from char

259 (ecoff_compute_section_file_positions): Save the size of the

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

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

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

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

439 the DYNAMIC flag for the BFD.
440 (NAME(bfd_elf,write_object_contents)): Don't try to write out a
441 BFD with the DYNAMIC flag set, since we don't generate the program
