Update.
2003-08-07  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/generic/ldsodefs.h (_rtld_global): Add
	_dl_rtld_lock_recursive and _dl_rtld_unlock_recursive.
	* elf/rtld.c (rtld_lock_default_lock_recursive,
	rtld_lock_default_unlock_recursive): New functions.
	(dl_main): Initialize _dl_rtld_lock_recursive and
	_dl_rtld_unlock_recursive.

2003-08-05  Jakub Jelinek  <jakub@redhat.com>

	* elf/ldconfig.c (main): Append SLIBDIR and LIBDIR to
	config_file directories instead of prepending.
