1997-01-23 Paul Eggert <eggert@twinsun.com> * mktime.c (mktime): Invoke __tzset, not __tzset_internal, to set tz, so that tzname is set as POSIX requires. Fri Jan 24 02:49:18 1997 Ulrich Drepper <drepper@cygnus.com> * dirent/dirent.h: Declare readdir_r also when __USE_POSIX. * grp/grp.h: Declare *_r functions also when __USE_POSIX. * pwd/pwd.h: Likewise. * time/time.h: Likewise. * posix/unistd.h: Declare ttyname_r also when __USE_POSIX. * string/string.h: Declare strtok_r also when __USE_POSIX. * stdio-common/bug7.c: Use tmpnam to generate names for test files. * stdio-common/tmpnam.c: Update copyright. * stdio-common/tmpnam_r.c: Likewise. * sysdeps/unix/sysv/linux/alpha/sys/kernel_termios.h: Protect against multiple inclusion. Include <termbits.h>. * sysdeps/unix/sysv/linux/sys/kernel_termios.h: Likewise. * sysdeps/unix/sysv/linux/net/if.h: Update according to recent kernel headers. Patch by Philip Blundell <pjb27@cam.ac.uk>. Thu Jan 23 17:42:00 1997 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sparc/clone.S: Correct author attribution. * sysdeps/unix/sysv/linux/net/if_arp (MAX_ADDR_LEN): Add definition. Thu Jan 23 14:20:34 1997 Ulrich Drepper <drepper@cygnus.com> * time/tzfile.c (__tzfile_read): Don't allow arbitrary files to be read when running a setuid program.
