Ulrich Drepper f516442913 Update.
2004-06-30  Ulrich Drepper  <drepper@redhat.com>

	* include/net/if.h: Handle if_nameindex and if_freenameindex with
	libc_proto_hidden.
	* sysdeps/unix/sysv/linux/netlinkaccess.h: New file.
	* sysdeps/unix/sysv/linux/ifaddrs.c: Export netlink handling functions.
	* sysdeps/unix/sysv/linux/if_index.c (if_nameindex): Implement using
	netlink if possible.  Fall back on ioctl method if necessary.

	* include/unistd.h: Declare __truncate.
	* sysdeps/generic/truncate.c: Also define __truncate.
	* sysdeps/mach/hurd/truncate.c: Likewise.
	* sysdeps/unix/common/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/truncate64.c: Use __truncate, not truncate.
