Ulrich Drepper 2eb45444a7 Update.
1998-03-04 16:12  H.J. Lu  <hjl@gnu.org>

	* libio/strops.c (_IO_str_seekoff): Handle MODE == 0.

1998-03-04 16:19  Ulrich Drepper  <drepper@cygnus.com>

	* nscd/nscd_getgr_r.c: Follow nscd_getpw_r.c change.

1998-03-04  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* nscd/nscd_getpw_r.c (nscd_open_socket): Safe and reset errno so
	that a failure to connect to nscd doesn't change errno.

1998-03-04  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* manual/maint.texi (Reporting Bugs): Change
	bug-glibc@prep.ai.mit.edu to bug-glibc@gnu.org.

	* locale/iso-4217.def: Likewise

1998-03-04 12:43  Ulrich Drepper  <drepper@cygnus.com>

	* manual/texinfo.tex: Updated.

1998-03-03  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/posix/fpathconf.c: Don't modify errno for an undefined
	value.
	* sysdeps/posix/pathconf.c: Likewise.
	* posix/getconf.c: Print `undefined' if pathconf returns -1
	without setting errno.

1998-03-04  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Fix cut&paste
	problem.
