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

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

131 section has already been created with the right size.
132 (coff_write_symbols): Initialize debug_string_size to 0. If
133 bfd_coff_symname_in_debug returns true, don't put symbol name in
134 usual string table. After writing out all symbols, if
135 debug_string_size is not 0, check that it matches the size of the

158 * ecofflink.c (bfd_ecoff_debug_externals): If a small undefined
159 symbol has a value in the ECOFF symbol but not in the BFD symbol,
160 keep the value in the ECOFF symbol. This helps gas.
162 * linker.c (_bfd_generic_link_output_symbols,
163 _bfd_generic_link_write_global_symbol): Don't require that all
164 references to a common symbol be themselves common symbols.

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

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

309 (ecoff_compute_section_file_positions): Save the size of the

326 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
327 get the index of a common section, rather than always using
328 SHN_COMMON (MIPS has multiple common sections).
330 * elf32-hppa.c (hppa_elf_gen_reloc_type): Typo (== for =).
332 * bfd/aoutx.h (aout_link_input_section_std,

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

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

431 read_dynamic_relocs fields.
432 * aout-target.h (MY(backend_data)): Initialize

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