Ulrich Drepper 3081378bb2 Update.
1998-05-19 15:58  Ulrich Drepper  <drepper@cygnus.com>

	* elf/rtld.c (process_envvars): Fix typo.  Don't handle
	LD_PROFILE_OUTPUT in SUID binaries.
	* intl/dcgettext.c: In SUID binaries don't let language part of
	locale value contain path elements.
	* intl/explodename.h: Define new function _nl_find_language.
	* intl/loadinfo.h: Declare _nl_find_language.
	* locale/findlocale.c (_nl_find_locale): Use _nl_find_locale to get
	language part it drop the value is path element is contained.

	* locale/setlocale.c: Fix typo.

1998-05-18  Philip Blundell  <Philip.Blundell@pobox.com>

	* sysdeps/unix/sysv/linux/arm/socket.S: Correct handling of arguments.

	* sysdeps/arm/strlen.S: Support both big and little endian processors.

	* sysdeps/arm/sysdep.h (ALIGNARG): ELF .align directive uses a
	log, not a byte-count.

	* sysdeps/unix/arm/sysdep.S (syscall_error): Use C_SYMBOL_NAME for
	a.out compatibility.

1998-05-19  Andreas Jaeger  <aj@arthur.rhein-neckar.de>
