* som.c, som.h (bfd_som_set_section_attributes,
bfd_som_set_subsection_attributes): Change parameters from char
to int. Following a prototype with an old-style function definition
in the presence of widened parameters is a GCC-ism not supported
by the HP compiler in ANSI mode.
Tue Jan 25 11:46:46 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* reloc.c (bfd_get_reloc_size): Size of type -2 is 4 bytes, not 2.
* hp300hpux.c (MY(write_object_contents)): Write out the symbols
before writing out the relocs, so that the right symbol indices
are used.
* archive.c (do_slurp_bsd_armap, bfd_slurp_bsd_armap_f2): Do not
try to overlay the internal carsyms on the external symdefs. That
can not work if the size of a host pointer is larger than 4 bytes.

bfd_xmalloc_by_size_t.
* opncls.c (_bfd_new_bfd): Avoid ANSI C prototype.

symbols.

undefined, look it up in the linker hash table.
* aoutx.h (translate_symbol_table): The string index 0 has a

* nlmcode.h, liblnm.h, nlm32-alpha.c nlm32-i386.c nlm32-sparc.c:
The sparc (and possibly other?) NLM format requires a different
way to write exports, so add a write_export field to the backend
data (and set it to NULL for everything but the sparc).
Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
