Update.

2000-08-19  Ulrich Drepper  <drepper@redhat.com>

	* elf/Versions [ld] (GLIBC_2.2): Export _dl_check_map_versions.
	* elf/dl-deps.c (_dl_map_object_deps): If object was dependency of
	a dynamically loaded object remove old l_initfini list.
	* elf/dl-libc.c (free_mem): Used as __libc_subfreeres callback to
	remove some dynamically allocated memory blocks in the dynamic
	loading data structures.
	* elf/dl-load.c (add_name_to_object): Initialize dont_free to 0.
	* elf/dl-open.c (dl_open_workder): Don't call _dl_check_all_versions.
	Instead call _dl_check_map_versions only for the dependencies.
	* elf/rtld.c: Avoid unneccessary initializations.  Mark l_libname
	information of initial objects as not free-able.
	* sysdeps/generic/ldsodefs.h (struct libname_list): Add dont_free
	element.

	* elf/filter.c: Call mtrace.
	* elf/restest1.c: Likewise.  Close the objects.
	* elf/loadtest.c: Call mtrace.  Check result of dlclose.  Print more
	debug information.

	* elf/constload1.c: Add comment explaining not freed memory.
