Thu Jun 8 02:50:26 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>

	* elf/rtld.c [! NDEBUG] (__assert_perror_fail): New function.

	* hurd/hurdstartup.c (_hurd_startup): Fancier kludge to guess phdr
 	and user entry point addresses.

	* elf/dl-load.c (open_path): Don't do strlen on DIRPATH if it's null.
	(_dl_map_object): DT_RPATH value is relative to DT_STRTAB value.

	* Makerules (install-lib.so): Don't include libc.so.
	[$(build-shared)=yes] (install): Depend on the installed libc.so file.
	[$(build-shared)=yes] (install-no-libc.a): Make this, rather than
	install, depend on the installed $(install-lib.so) files.
	[$(build-shared)=yes] (install-lib.so): Append libc.so after that rule.

	* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): Add kludge to
 	allocate high addresses to avoid random mappings appearing there.
	(mmap): Comment out mask; always pass zero.

	* sysdeps/i386/dl-machine.h (ELF_MACHINE_USER_ADDRESS_MASK): New macro.
	* sysdeps/mach/hurd/dl-sysdep.c (mmap): Use it as mask in vm_map call.

	* elf/dl-error.c (_dl_catch_error): Clear *ERRSTRING and *OBJNAME
 	when successful.

	* sysdeps/mach/hurd/dl-sysdep.c (threadvars): New static variable.
	(__hurd_threadvar_max, __hurd_threadvar_stack_offset): Define these
	variables, using the `threadvars' buffer.

	* elf/dl-reloc.c: Don't dereference L->l_prev when it's null.
	* sysdeps/i386/dl-runtime.c: Likewise.

	* elf/rtld.c (dl_main): Add missing NULL terminating argument in
 	_dl_sysdep_fatal call.
	(__assert_fail): Likewise.

	* locale/Makefile (localedef-modules): Renamed ctype to
 	locale-ctype so as not to conflict with the object file for
 	ctype/ctype.c in the build directory.

	* sysdeps/i386/dl-machine.h (elf_machine_rel): If MAP->l_type is
 	lt_interpreter, first undo relocation done during bootstrapping.
