update from main archive 970122 cvs/libc-970124
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.
