update from main archive 961109

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.

	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>

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

	(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.

	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.

	(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>.

very strange errors at run time.
- Macro: _REENTRANT,_THREAD_SAFE
If you define one this macro, reentrant versions of several
functions get declared. Some of the functions are specified in
POSIX.1c but many others are only available on a few other systems
or are unique to GNU libc. The problem is that the
standardization of the thread safe C library interface still is
behind.
Unlike on some other systems no special version of the C library
must be used for linking. There is only one version but while
compiling this it must have been specified to compile as thread
safe.
We recommend you use `_GNU_SOURCE' in new programs. If you don't
specify the `-ansi' option to GCC and don't define any of these macros
explicitly, the effect is the same as defining `_GNU_SOURCE'.
