Update.

1998-04-24  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* streams/Makefile (headers): Add sys/stropts.h.
	* streams/sys/stropts.h: New file.

1998-04-25  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/ttyname.c,
	sysdeps/unix/sysv/linux/ttyname_r.c: New files, like
	sysdeps/posix/ttyname*.c, but look in /dev/pts first.

1998-04-25  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/ptsname.c: Fix off-by-one bug in second
	argument of _itoa_word.

1998-04-24  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/syscalls.list (s_getcwd, s_getdents,
	s_pread64, s_pwrite64, s_reboot, s_sigpending, s_sigprocmask): Set
	caller to getcwd, getdents, pread64, pwrite64, reboot, sigpending,
	sigprocmask, resp., instead of EXTRA.

	* sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Remove
	s_pread64 and s_pwrite64.
