Sat Dec  7 03:24:36 1996  Ulrich Drepper  <drepper@cygnus.com>

	* configure.in: Discard error message from test in test for
	bash-2.0.

	* io/getpw.c: Don't apply getcwd on user supplied buffer.
	Instead always use temporary buffer and only copy the result.
	Patch by HJ Lu.
	* stdlib/canonicalize.c: Likewise.

	* libio/fileops.c: Change comments according to libg++2.8b5.
	* libio/iosetvbuf.c: Follow change in libg++-2.8b5 to clear
	unbuffered flag.
	Reported by HJ Lu.

	* manual/nss.texi: Correct prototypes.

	* misc/syslog.c: Make reentrant.  Catch SIGPIPE signal to prevent
	crash if syslog daemon is restarted.

	* stdlib/rand_r.c: New file.  Implementation of POSIX.2 function
	rand_r.
	* stdlib/Makefile (routines): Add rand_r.

	* sysdeps/stub/libc-lock.h: Define __libc_lock_trylock and
	__libc_mutex_lock.

	* configure.in: Add --disable-sanity-check option.
	* sysdeps/unix/sysv/linux/configure.in: If linuxthreads or
	des-crypt are not available and --disbale-sanity-check is not
	given abort with a message.

Thu Dec  5 19:19:53 1996  Richard Henderson  <rth@tamu.edu>

	* posix/glob.c: Tests against STDC_HEADERS should also test
	__GNU_LIBRARY__.

Thu Dec  5 16:20:55 1996  Ulrich Drepper  <drepper@cygnus.com>

	* misc/err.c (vwarn): Set errno again before using %m format.

Thu Dec  5 10:14:05 1996  Andreas Jaeger  <aj@arthur.pfalz.de>

	* grp/grp.h: Add declaration of __getgrent_r.

	* io/fts.c (fts_build): Remove "register" from variables dirbuf
	and dp since their address is needed.

	* sysdeps/posix/getcwd.c (__getcwd): Remove "register" from
	variable d since d's address is needed.

	* misc/tst-dirname.c (main): Provide prototype.
	* misc/ioctltst.c (main): Dito.

	* Makefile: Add gnu/lib-names.h to install-others before including
	Makerules.

Wed Dec  4 16:00:09 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/sys/socketvar.h: New file.  Simply use
	<sys/socket.h>.
	* sysdeps/unix/sysv/linux/Dist: Add sys/socketvar.h.
	* sysdeps/unix/sysv/linux/Makefile [$(subdir)=inet)]: Add
	sys/socketvar.h to sysdep_headers.

	since the value might be outside the range of the `long int'.
