update from main archive 961008 cvs/libc-961009

Wed Oct  9 00:30:33 1996  Ulrich Drepper  <drepper@cygnus.com>

	* inet/getnetgrent_r.c: Correct netgroup implementation.  A
	specification of a netgroup can also name another netgroup.
	* nss/nss_files/files-netgrp.c: Likewise.
	* inet/netgroup.h: Add fields to hold additional information.

Tue Oct  8 21:51:14 1996  Arnold D. Robbins  <arnold@skeeve.atl.ga.us>

	* posix/getopt.c: Implement POSIX -W option handling.  When the
	option string contains "W;" -W foo is handled like --foo.

Tue Oct  8 12:27:26 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/i386/clone.S: Define _ERRNO_H before
	inclusing <errnos.h> so we really get error symbols defined.
	* sysdeps/unix/sysv/linux/m68k/clone.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/clone.S: Likewise.

	* sunrpc/auth_unix.c (authunix_create_default): Don't use fixed
	size array for getgroups call.  Instead get maximal number via
	sysconf.  But discard list to NGRPS elements before calling XDR
	function since Sun's code cannot handle longer lists.
	Based on a patch by Thorsten Kukuk <kukuk@weber.uni-paderborn.de>.

	* sysdeps/stub/e_j0l.c: Define y0l as well.
	* sysdeps/stub/e_j1l.c: Define y1l as well.
	* sysdeps/stub/e_jnl.c: Define ynl as well.

	* posix/unistd.h: Correct prototype for execlp.

	* sysdeps/unix/sysv/linux/posix_opt.h: Define _POSIX_NO_TRUNC.

Mon Oct  7 22:18:03 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makeconfig (sysdep-library-path): New variable.
	(built-program-cmd): Use it here to properly build a colon
	separated library path.

Mon Oct  7 22:11:55 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* crypt/md5-crypt.c (md5_crypt_r): Add missing parens around &
	within comparison.  Fix comments.
	(md5_crypt): Fix comment.

Tue Oct  8 05:10:49 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/errnos.h: Only include <linux/errnos.h>
	when _ERRNO_H is defined.
	[!_ERRNO_H && __need_Emath]: Define value for EDOM and ERANGE.
	Should there ever be a Linux port where the numeric values are
	not 33 and 34 this file must change.

Mon Oct  7 13:54:04 1996  Ulrich Drepper  <drepper@cygnus.com>

	* libio/iofgets.c (_IO_fgets): Use _IO_flockfile instead of
	__flockfile.

Mon Oct  7 11:01:45 1996  Andreas Jaeger  <aj@arthur.pfalz.de>

	* string/tst-strlen.c (main): Provide prototype.
	* malloc/mallocbug.c: Likewise.
	* io/test-utime.c: Likewise.

	* sysdeps/generic/crypt-entry.c: Correct typo.

Mon Oct  7 13:42:20 1996  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-open.c (_dl_open): Check against _dl_sysdep_start to
	test for libc.a.  Checking _DYNAMIC is of no worth here.
	Suggested by Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>.

	* nss/nss_files/files-parse.c: Define LOOKUP_NAME even if
 	EXTERN_PARSER is defined.

Sat Oct  5 17:05:36 1996  Andreas Jaeger  <aj@arthur.pfalz.de>

	* Rules (dep-dummy-lib): Correct prototype for __dummy__.

	* crypt/md5-crypt.c: Fix typos in comments.

	* gmon/gmon.c: Provide prototypes.
	* db/makedb.c: Likewise.
	* locale/programs/xmalloc.c: Likewise.
	* stdio-common/bug11.c (main): Likewise.
	* stdio-common/bug7.c (main): Likewise.
	* stdio-common/bug8.c (main): Likewise.
	* stdio-common/bug9.c (main): Likewise.
	* stdio-common/scanf1.c (main): Likewise.
	* stdio-common/scanf2.c (main): Likewise.
	* stdio-common/scanf5.c (main): Likewise.
	* stdio-common/scanf6.c (main): Likewise.
	* stdio-common/scanf7.c (main): Likewise.
	* stdio-common/scanf8.c (main): Likewise.
	* stdio-common/temptest.c (main): Likewise.
	* stdio-common/test-fwrite.c (main): Likewise.
	* stdio-common/tst-printf.c: Likewise.
	* stdio-common/tstdiomisc.c: Likewise.
	* stdio-common/tstgetln.c (main): Likewise.
	* stdlib/testmb.c (main): Likewise.

	* stdio-common/scanf4.c (main): Correct prototype, remove unused
	variable n.

	* stdio-common/scanf3.c (main): Correct prototype, change
	declaration of s to reduce warnings.
	* stdio-common/bug10.c (main): Likewise.

	* stdio-common/tfformat.c: Provide prototype, remove unused
	reference to dump_stats, add braces in sprint_doubles.
	* stdio-common/tiformat.c: Likewise.

	* stdio-common/test_rdwr.c (main): Parameter `where' is long in
	printf call.

Mon Oct  7 14:04:26 1996  NIIBE Yutaka  <gniibe@mri.co.jp>

	* sysdeps/unix/sysv/linux/sys/soundcard.h: Fix typo.

	* shadow/putspent.c: Don't write colon after flag field.

	* sysdeps/unix/sysv/linux/net/if_ppp.h: New file.  Wrapper around
	kernel header.
	* sysdeps/unix/sysv/linux/net/ppp-comp.h: Likewise.
	* sysdeps/unix/sysv/linux/net/ppp_defs.h: Likewise.
	* sysdeps/unix/sysv/linux/Dist: Mention new files.

Mon Oct  7 00:58:19 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/i386/i586/strchr.S: Correct handling of first bytes to
	get pointer aligned.  Reported by Matthias Urlichs <smurf@noris.de>.

	* sysdeps/posix/euidaccess.c [_LIBC]: Avoid calling get?id functions
	by using __libc_enable_secure variable.

	* sysdeps/libm-i387/s_copysignl.S: Correct loading of return value.
