update from main archive 961127 cvs/libc-961128
Thu Nov 28 03:11:11 1996 Ulrich Drepper <drepper@cygnus.com> * libio/fileops.c: Update from latest libg++. * sysdeps/unix/sysv/linux/init-first.c: Reformat copyright. * sysdeps/stub/libc-lock.h: Add __libc_lock_init_recursive. * libio/genops.c (_IO_init): Use __libc_lock_init_recursive instead of __libc_lock_init for streams. 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 [$(subdir)=csu]: Add errno-loc to sysdep-routines. * sysdeps/unix/sysv/linux/configure: Add test for linuxthreads and crypt add-on and warn if not available. Wed Nov 27 23:09:37 1996 Ulrich Drepper <drepper@cygnus.com> * po/ko.po: Update from Bang Jun-Young <bangjy@nownuri.nowcom.co.kr>. * sysdeps/unix/sysv/linux/syscalls.list: Remove _llseek. * sysdeps/unix/sysv/linux/Makefile [$(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.
