	* elf/dl-lookup.c (_dl_lookup_symbol): If no value and *REF is
	null, consider it a strong reference and give the error.

Wed Jun 12 15:52:46 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* elf/dl-open.c (_dl_open): Correctly terminate relocating loop
 	after relocating NEW when it's the only new object.

	* elf/dl-init.c (_dl_init_next): When out of initializers, set
 	_r_debug.r_state to RT_CONSISTENT and call _dl_debug_state just
 	before return.

	* elf/rtld.c (dl_main): Move _dl_debug_initialize call after
 	relocation.  Call it unconditionally and only fill in DT_DEBUG
 	if it's present.  Then call _dl_debug_state with r_state RT_ADD
 	before running initializers.

	* elf/dl-open.c (_dl_open): Call _dl_debug_initialize and then call
 	_dl_debug_state with r_state RT_ADD before running initializers
	* elf/dl-close.c (_dl_close): Call _dl_debug_state with r_state
 	RT_DELETE before running finalizers and with RT_CONSISTENT just
 	before return.

	* elf/Makefile (dl-routines): Add dl-debug.
	* elf/dl-debug.c: New file.
	* elf/rtld.c (_dl_r_debug): Rename to _r_debug and move to dl-debug.c.
	(_dl_r_debug_state): Rename to _dl_debug_state and likewise move.
	(dl_main): Use _dl_debug_initialize.
	* elf/link.h: Fix name to _dl_debug_state in decl.
	(_dl_debug_initialize): Declare new function from dl-debug.c.
	(_r_debug): Declare it.

	* Makerules (distinfo-vars): Add install-{lib,data,bin,sbin,others}.
	In distinfo set $(subdir)-VAR and then set VAR to $($(subdir)-VAR).

	* Makeconfig (rpath-link): New variable; add $(elfobjdir).
	(default-rpath): Use it.
	(built-program-cmd): Use it in LD_LIBRARY_PATH.

	* Makeconfig (sysdep-configures): Prepend $(sysdep_dir) to names tried.

	* sysdeps/unix/Dist: Add make-syscalls.sh.

	* misc/Makefile (headers): Add sys/swap.h.
	* posix/unistd.h: Remove decls for swapon, swapoff.
	* sysdeps/generic/sys/swap.h: New file.
	* sysdeps/unix/sysv/linux/sys/swap.h: New file.

	* sysdeps/unix/sysv/linux/gnu/types.h: Remove temporary hack #define
	of __kernel_fsid_t.  It is correctly defines in <linux/types.h> now.
