2001-07-06  Paul Eggert  <eggert@twinsun.com>

	* manual/argp.texi: Remove ignored LGPL copyright notice; it's
	not appropriate for documentation anyway.
	* manual/libc-texinfo.sh: "Library General Public License" ->
	"Lesser General Public License".

2001-07-06  Andreas Jaeger  <aj@suse.de>

_POSIX_V6_ILP32_OFFBIG 32bit int, long, and pointers and larger off_t type

_XBS5_LPBIG_OFFBIG were used in previous versions of the Unix standard
and are available only for compatibility.
