	* elf/dl-close.c: Include <string.h> for memcpy.
	* elf/dl-lookup.c: Same.

	* elf/elf.h: Add Elfxx_Symndx for symbol indices.
	* elf/dl-lookup.c (_dl_lookup_symbol): Use it.
	(_dl_setup_hash): Use it.
	* elf/link.h (struct link_map): Use it.

	* elf/rtld.c (_dl_start): Don't rely on pointer-to-first-arg hack
	for getting the argc/argv/envp block.  Instead, make it the argument.
	sysdeps/i386/dl-machine.h (RTLD_START): Do that.
	sysdeps/m68k/dl-machine.h (RTLD_START): Same.

	* shlib-versions: Add version numbers for alpha-linux.  To avoid
	user confusion, make them the same as i386-linux.

	* sysdeps/alpha/Makefile [subdir elf]: Add -mno-fp-regs to
	sysdep-CFLAGS so that _dl_runtime_resolve doesn't have to save them.
	Add -mbuild-constants to CFLAGS-rtld.c to that we can bootstrap
	without using literal data.

	* sysdeps/generic/dl-sysdep.c: Include <string.h> for memcpy.
	Finish Elf32 -> ElfW migration.
