Update.
* iconv/iconv_prog.c (main): Handle input file name "-" correctly. Recognize option -s, -c, and -l. 2000-04-20 Thorsten Kukuk <kukuk@suse.de> * nscd/nscd.c: Start new session for nscd, drop privilegs to configured user if requested and no -S parameter are used. * nscd/nscd.conf: Add new option "server-user". * nscd/nscd_conf.c: Add support for new "server-user" option. * nscd/nscd.h: Add declaration for server_user variable. Based on patch by Chris Wing <wingc@engin.umich.edu> 2000-04-29 Mark Kettenis <kettenis@gnu.org> * sysdeps/unix/sysv/linux/i386/sigaction.c: Add comment explaining that changing the __restore and __restore_rt signal return code will break GDB. 2000-04-29 Mark Kettenis <kettenis@gnu.org> * sysdeps/unix/sysv/linux/i386/sys/ucontext.h: Do not include <sys/user.h>. 2000-04-29 Mark Kettenis <kettenis@gnu.org> * conform/data/ucontext.h-data: Allow ss_* instead of SS_*. 2000-04-29 Ulrich Drepper <drepper@redhat.com>
