	Reported by a sun <asun@zoology.washington.edu>.

	* sysdepsunix/sysv/linux/i386/brk.c: Reformat copyright.

	* sysdeps/generic/errno-loc.c: New file.  Generic definition of
	__errno_location function.
	* sysdeps/unix/sysv/linux/i386/sysdep.S: Remove definition of
	__errno_location.
	* sysdeps/unix/sysv/linux/m68k/sysdep.S: Likewise.
	* sysdeps/unix/sysv/linux/Makefile [$(subdir)=csu]: Add errno-loc
	to sysdep-routines.

	* sysdeps/unix/sysv/linux/configure: Add test for linuxthreads

Wed Nov 27 23:09:37 1996  Ulrich Drepper  <drepper@cygnus.com>

	* po/ko.po: Update from Bang Jun-Young <bangjy@nownuri.nowcom.co.kr>.

	* sysdeps/unix/sysv/linux/syscalls.list: Remove _llseek.
	* sysdeps/unix/sysv/linux/Makefile [$(subdir)=misc] (routines): Add
	llseek.
	* sysdeps/unix/sysv/linux/llseek.c: New file.  Uses syscall.
	* sysdeps/unix/sysv/linux/i386/syscalls.list: Add __sys_llseek.
	* sysdeps/unix/sysv/linux/m68k/syscalls.list: Add __sys_llseek.
	Reported by HJ Lu <hjl@gnu.ai.mit.edu>.
	* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add llseek.
	* sysdeps/unix/sysv/linux/alpha/llseek.S: Remove.  Generic syscall
	is enough.
	Patch by Richard Henderson <rth@tamu.edu>.

	* sysdeps/unix/sysv/linux/alpha/sys/io.h: Add prototypes for
	pciconfig_read and pciconfig_write.
	* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add new syscalls
	pciconfig_read and pciconfig_write.

	* login/getutent_r.c: Fix several bugs in last change.
