Mon Dec  2 03:59:38 1996  Ulrich Drepper  <drepper@cygnus.com>

	* grp/initgroups.c: Update and reformat copyright.
	Use __getgrent_r instead of getgrent.

	* inet/rcmd.c: Update and reformat copyright.
	Use __gethostbyname_r instead of gethostbyname.
	* inet/rexec.c: Likewise.

	* intl/finddomain.c: Correct comment about CEN sponsor and revision.
	* locale/findlocale.c: Likewise.
	* intl/l10nflist.c: Correct handling of CEN sponsor and revision.
	* locale/Makefile (CPPFLAGS): Add definition of LOCALEDIR.
	* locale/setlocale.c (setlocale): Correctly split value of
	LOCALE_PATH.
	* locale/programs/localedef.c: Use LOCALEDIR not LOCALE_PATH to
	find output directory.

	* nss/getXXbyYY.c [NEED_H_ERRNO]: Before enlarging buffer test
	h_errno_tmp variable.
	Save error value from being changed during `free' call.
	* nss/getXXent.c: Likewise.

	* nss/nss_files/files-XXX.c: Set h_errno variable to NETDB_INTERNAL
	before returning ERANGE error.

	* posix/glob.c: Use getlogin_r and getpwnam_r function when available
	or in GNU libc.

	* pwd/getpw.c: Use getpwuid_r instead of getpwuid.

	* sunrpc/clnt_gen.c: Use gethostbyname_r and getprotobyname_r.
	* sunrpc/clnt_simp.c: Likewise.
	* sunrpc/getrpcport.c: Likewise.
	* sysdeps/unix/sysv/linux/gethostid.c: Likewise.

	* posix/getconf.c: Treat _SC_UNIT_MAX and _SC_ULONG_MAX separately
	since the value might be outsode the range of the `long int'.
	Print string `undefined' when a value is undefined.

	* stdlib/l64a.c: Return correct pointer.
	Patch by NIIBE Yutaka <gniibe@mri.co.jp>.

	* string/Makefile (routines): Add argz-addsep.
	* string/argz-addsep.c: New file.
	* string/argz.h: Add prototypes for argz_add_sep.

	* string/argz-ctsep.c: Prevent memory leak.

	* string/strcoll.c: Correct typo in comment.

Sat Nov 30 02:53:59 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/sys/serial.h: Removed again.  The file is
	not general enough to be part of the libc.
	* sysdeps/unix/sysv/linux/Dist: Remove sys/serial.h.
	* sysdeps/unix/sysv/linux/Makefile: Don't install sys/serial.h.

Thu Nov 28 20:04:41 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* login/Makefile: Fix typo.

	* nss/Makefile (generated): Filter out db-alias.c.

Thu Nov 28 14:44:01 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* time/Makefile (echo-zonenames): Don't depend on non-existing
	target `zonenames'.

Thu Nov 28 12:34:05 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* link.h: New file.
	* nss/nsswitch.c: Use it.

	* printf.h: Fix file name.
	* stdlib/strfmon.c: Use it.
