Andreas Jaeger e25054c49c Update.
2000-05-17  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/generic/dl-cache.h (_DL_CACHE_DEFAULT_ID): Only define if
	not yet defined.
	(_dl_cache_check_flags): Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/dl-cache.h: include_next
	dl-cache.h.

	* manual/creature.texi (Feature Test Macros): Remove paragraph
	since the description is wrong.
	Closes PR libc/1691, reported by Geoff Clare <gwc@unisoft.com>.

2000-05-17  Andreas Jaeger  <aj@suse.de>

	* time/test_time.args: Removed.
	* time/Makefile (test_time-ARGS): Added contents here instead.

	* posix/tstgetopt.args: Removed.
	* posix/Makefile (tstgetopt-ARGS): Added contents here instead.

	* Rules: Allow arguments for test files to be specified in
	Makefile with testname-ARGS; remove rules with .args in it.

	* dirent/Makefile (opendir-tst1-ARGS): Use this for opendir-tst1,
	remove old bogus rule for opendir-tst1.args.

	* stdlib/test-canon.c: Rewrite to use test-skeleton.c.

	* stdlib/Makefile (test-canon-ARGS): New, supply argument to chdir
	into objdir.  This allows a readonly sourcetree.
	Reported by lrgallardo@yahoo.com, closes PR libc/1421.

2000-05-16  Andreas Jaeger  <aj@suse.de>,
            David Huggins-Daines <dhd@linuxcare.com>

	cache_data in case of only new cache format correctly.

	* sysdeps/generic/dl-cache.c (_dl_load_cache_lookup): Align struct
	cache_file_new.

	* sysdeps/generic/dl-cache.h (ALIGN_CACHE): New macro to align
	struct cache_file_new.

	* elf/cache.c (save_cache): Fix str_offset if only new cache is
	present.

	* elf/cache.c (save_cache): Align struct new_file_cache.
