74 * srec.c (srec_write_record): Put CONST keyword for "src" before
75 "unsigned", some compilers don't like it after "unsigned".
76 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

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

118 bfd_coff_symname_in_debug returns true, don't put symbol name in
119 usual string table. After writing out all symbols, if

144 symbol has a value in the ECOFF symbol but not in the BFD symbol,
145 keep the value in the ECOFF symbol. This helps gas.
147 * linker.c (_bfd_generic_link_output_symbols,
148 _bfd_generic_link_write_global_symbol): Don't require that all
149 references to a common symbol be themselves common symbols.

193 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
194 (only testing for m68k and vax at the moment); do verify that the

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

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

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

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