update from main archive 961109cvs/libc-961110

Sun Nov 10 02:37:15 1996  Ulrich Drepper  <drepper@cygnus.com>

	* inet/gethstent_r.c: Update copyright.
	* nss/getXXbyYY_r.c: Likewise.
	* nss/nsswitch.c: Likewise.
	* nss/getXXent_r.c: Likewise.
	* nss/nss_files/files-XXX.c: Likewise.
	* nss/nss_files/files-netgroup.c: Likewise.
	* nss/nss_files/files-parse.c: Likewise.

	* nss/getXXent_r.c: Change implementation.  It's not necessary to
	call all setXXent functions.  Just find first available and
	when necessary let getXXent_r call the others.

	* nss/nss_files/files-XXX.c: Make really reentrant.  Now calls
	of getXXent and getXXbyYY can be mixed.  The cursor for traversing
	the database with getXXent will be remembered.

	* stdlib/test-canon.c (cwd): Change size to PATH_MAX.

Sat Nov  9 15:34:48 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/Dist: Add sys/mtio.h.
	* sysdeps/unix/sysv/linux/sys/mtio.h: New file.

	* signal/signal.h [__USE_BSD]: Add prototype for siggetmask.

Fri Nov  8 13:29:30 1996  Ulrich Drepper  <drepper@cygnus.com>

	* ctype/ctype.h (__isascii): Don't test for seventh bit not to be
	set.  Instead for none beside the first seven bits to be set.
	X/Open allows the argument to be an `int' value.
	Reported by Alain Williams <addw@phcomp.co.uk>.
	(toascii, isascii): Define macro also when __USE_XOPEN.

	* sysdeps/posix/fpathconf.c: Use fstatfs to compute NAME_MAX, not
	PATH_MAX.

Thu Nov  7 03:04:29 1996  Ulrich Drepper  <drepper@cygnus.com>

	* nss/getXXXent_r.c (SETFUNC_NAME): Reset `nip' after loop to
	NULL so that GETFUNC will see first entry.
	(ENDFUNC_NAME): Likewise.

	Rewrite Netgroups implementation to avoid global data.
	* inet/netgroup.h: Add definition of name_list and struct
	__netgrent.
	Add prototypes for internal netgroup functions.
	* nss/nss_files/files-netgroup.c (_nss_files_setnetgrent): Take
	extra argument and use the included data instead of global vars.
	(_nss_files_endnetgrent): Likewise.
	(_nss_netgroup_parseline): Change to be static and use data
	included in the RESULT structure.
	* inet/getnetgrent_r.c (startp): Move into setup function.
	(known_groups, needed_groups): new part of the __netgrent sruct.
	(freememory): Take extra argument and use included data.
	(__internal_endnetgrent): Likewise.
	(internal_setnetgrent): Renamed to __internal_setnetgrent_reuse
	and take extra argument.
	(__internal_setnetgrent): New function.  Call
	__internal_setnetgrent_reuse after calling free_memory.
	(setnetgrent): Only call __internal_setnetgrent.
	(__getnetgrent_r): Split into two functions.  __getnetgrent_r
	calls __internal_getnetgrent after locking.
	(innetgr): Use dynamic data only.  I.e., innetgr now is fully
	reentrant.

Thu Nov  7 00:15:14 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/stub/setenv.c: Correct typo: unseenv -> unsetenv.
	Reported by Joshua Cowan <jcowan@jcowan.reslife.okstate.edu>.

Wed Nov  6 13:13:37 1996  Ulrich Drepper  <drepper@cygnus.com>

	* manual/creature.texi: Document that _GNU_SOURCE is no longer the
	default when no *_SOURCE macro is given.
	Reported by Karsten Weiss <karsten@addx.au.s.shuttle.de>.
	* NOTES: remade from manual/creature.texi.
	* manual/libc.texinfo: Add back line about GPL translation which
	somehow got lost.

	* Make-dist (dist.tar): Depend on README being updated.

	* rellns-sh: Correct thinko in removing leading /.
	Reported by Andreas Jaeger <aj@arthur.pfalz.de>.

	* pwd/fgetpwent_r.c: Recognize lines containing only names starting
	with `+' or `-' in parser.
	* grp/fgetgrent_r.c: Likewise.
	* shadow/sgetspent_r.c: Likewise.
	* nss/nss_files/files-spwd.c: Don't accept entries starting with
	`+' or `-'.

	* sysdeps/stub/lchown.c: New file.
