* elfcode.h (elf_new_section_hook): Do nothing for now.
	(elf_write_object_contents): Output common symbols the way ELF
	wants them.

Wed Jun 23 16:20:07 1993  Ken Raeburn  (raeburn@poseidon.cygnus.com)

	* libelf.h (struct elf_obj_tdata and associated macros): Moved
	here from elfcode.h.  A couple of size-specific structure pointers
	were changed to PTR; uses fixed appropriately.
	(elf32_symbol_type, elf64_symbol_type): Separated definitions.
	(bfd_elf_mkobject): Renamed from bfd_elf32_mkobject.
	(bfd_elf32_mkobject, bfd_elf64_mkobject, elf_mkobject): New
	temporary macros to ease name change.
	* elf.c (elf_read, elf_mkobject, elf_get_str_section,
	elf_string_from_elf_section, bfd_elf_find_section): Moved here
	from elfcode.h.
	* doc/Makefile.in (libbfd.h): Process elf.c too.
	* Makefile.in (elf.o): Note new dependencies.

	* elfcode.h: Lots of stuff moved elsewhere.  Deleted some unused
	code, tweaked some debug hooks.
	(elf_slurp_reloca_table): Translate ELF section symbols into BFD
	section symbols.
