32-bit host values. * libbfd.c (bfd_xmalloc_by_size_t): New function. * opncls.c (bfd_cache_init, bfd_open_file): Add prototypes to declarations. (obstack_chunk_alloc): Use bfd_xmalloc_by_size_t. (new_bfd): Prototype-style definition, using DEFUN. (bfd_alloc_grow, bfd_alloc, bfd_zalloc, bfd_realloc): Size argument is type size_t, not bfd_size_type. * ieee.c (obstack_chunk_alloc): Use bfd_xmalloc_by_size_t. * bfd.c (bfd_default_error_trap, bfd_error_trap, bfd_error_nonrepresentabltrap): Prototypes. * libbfd-in.h (bfd_alloc, bfd_zalloc, bfd_realloc, bfd_alloc_grow): Adjusted prototypes for arg type change. * archive.c (get_elt_at_filepos, do_slurp_bsd_armap, normalize, do_slurp_coff_armap, bfd_construct_extended_name_table): Prototypes.
