* elf/rtld.c (dl_main): Take new option --verify when run directly.
	In verify mode, exit with status zero iff the argument object's
	PT_INTERP matches argv[0].
	* elf/ldd.sh.in: Use ${RTLD} --verify and only run the program if it
	exits with zero status.  This makes `ldd' secure again.

Fri Jul 26 22:49:58 1996  Ulrich Drepper  <drepper@cygnus.com>

	* elf/rtld.c (dl_main): Implement LD_TRACE_LOADED_OBJECTS
	environment variable handling.  This makes the dynamic linker
	only print loaded libraries and quit.

	* elf/ldd.sh.in: Don't use `rtld --list' but instead
	LD_TRACE_LOADED_OBJECTS environment variable to print needed
	objects.

Sat Jul 27 02:03:26 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* db/makedb.c (main): Print version on stdout, not stderr.  Don't exit
	after printing version until after doing usage for --help.
	(long_options, main, usage): Rename -l/--lowercase option to
	-f/--fold-case (-f matches sort).

Sat Jul 27 04:32:31 1996  Ulrich Drepper  <drepper@cygnus.com>

	* db/makedb.c: New file.  Implement program to create simple <db.h>
	database from textual input.  This will be used for nss_db.

Sat Jul 27 01:24:05 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* sunrpc/rpc/auth_unix.h: Fix misapplied patches in last changes.
	* sunrpc/rpc/pmap_clnt.h: Likewise.
	* sunrpc/rpc/auth.h: Likewise.
	* sunrpc/rpc/pmap_rmt.h: Likewise.
	* sunrpc/rpc/rpc_msg.h: Likewise.

Sat Jul 27 04:37:34 1996  Ulrich Drepper  <drepper@cygnus.com>

	* string/string.h (strndupa): Change to use return value of
	`memcpy' for more performance.
	* string/strndup.c: Likewise.

	* string/string.h (strdupa): Don't call __builtin_alloca in argument.
	This might lead to problems.
	(strndupa): Likewise.
