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> * sysdeps/unix/bsd/vax/vfork.S: Fix the "the the" problems. * sysdeps/unix/bsd/sun/m68k/vfork.S: Likewise. * sysdeps/unix/bsd/hp/m68k/vfork.S: Likewise. * posix/unistd.h: Likewise. * math/math.h: Likewise. * manual/users.texi (Manipulating the Database): Likewise. * manual/signal.texi (Job Control Signals): Likewise. * manual/message.texi (The gencat program): Likewise. * manual/filesys.texi (Hard Links): Likewise. * manual/math.texi (SVID Random): Likewise. * manual/llio.texi (Waiting for I/O): Likewise. * manual/io.texi (File Name Errors): Likewise. * manual/conf.texi (String Parameters): Likewise. * manual/arith.texi (Infinity): Likewise. * malloc/malloc.c: Likewise. * hurd/hurdsig.c (_hurd_internal_post_signal): Likewise. * csu/Makefile: Likewise.
