Update.

2000-06-09  Ulrich Drepper  <drepper@redhat.com>

	Rewrite error message handling.
	* elf/dl-deps.c (_dl_map_object_deps): Pass new parameter to
	_dl_catch_error.
	* elf/dl-error (struct catch): Add objname member.
	(_dl_signal_error): Take new parameter with object name.  When
	passing message on simply store object name and duplicate error
	message.
	(_dl_catch_error): Take new parameter.  Store object name in the
	place pointed to.
	* include/dlfcn.h: Adjust _dl_catch_error prototype.
	* sysdeps/generic/ldsodefs.h: Adjust _dl_signal_error prototype.
	* elf/dl-libc.c (dlerror_run): Pass new parameter to _dl_catch_error.
	* elf/dl-open.c (_dl_open): Likewise.
	* elf/rtld.c (dl_main): Likewise.
	* elf/dl-close.c: Mark error messages with N_().
	* elf/dl-deps.c: Likewise.
	* elf/dl-error.c: Likewise.
	* elf/dl-load.c: Likewise.
	* elf/dl-open.c: Likewise.
	* elf/dl-reloc.c: Likewise.
	* elf/dl-support.c: Likewise.
	* elf/dl-sym.c: Likewise.
	* elf/dl-version.c: Likewise.
	* elf/dl-lookup.c: Add comments about problems with error message
	translations.
	* elf/dl-reloc.c: Likewise.
	* elf/dl-version.c: Likewise.
