Thu Nov 16 06:07:49 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>cvs/libc-951117

	* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start_cleanup): New
	function.
	(_dl_sysdep_start): Move cleanup code there.

	* Makeconfig (default-rpath): New variable.
	(link-libc): Use it.
	* elf/Makefile (ld.so): Pass -rpath=$(default-rpath).
	* elf/rtld.c (_dl_rpath): New variable.
	(_dl_start): Set it from rtld_map's DT_RPATH.
	Call _dl_setup_hash on rtld_map.
	(dl_main): Cache address of _exit in variable before relocating,
	and use that in later calls.  Call _dl_sysdep_start_cleanup before
	relocating.  Keep track of dependency order while loading; remove
	rtld_map from chain, and reinsert in proper order if there is a
	dependency on it.

	* sysdeps/generic/Makefile (make_siglist): Pass
	-DSIGNUM_H=... with config's signum.h location.
	* sysdeps/generic/make_siglist.c: Include SIGNUM_H to define
	signal numbers.
	(HAVE_STRSIGNAL, HAVE_PSIGNAL): Define these before including signame.c
	(main): Deansideclize output.

	* elf/dl-load.c (_dl_map_object): Use _dl_rpath variable in place
	of DEFAULT_RPATH macro.
	* elf/Makefile: Undo last change.

	* sysdeps/mach/hurd/dl-sysdep.c (free): Don't abort, just nop.
