Update.

1998-03-29 16:50  Ulrich Drepper  <drepper@cygnus.com>

	* config.make.in (ldd-rewrite-script): New variable.
	* configure.in: Substitute ldd-rewrite-script.
	* elf/Makefile: Rewrite rules to generate ldd script.
	* elf/ldd.bash.in: Allow handling of non-ELF binaries.
	* elf/ldd.sh.in: Likewise.
	* sysdeps/unix/sysv/linux/Makefile: Remove rule to install lddlibc4.
	* sysdeps/unix/sysv/linux/configure.in: Define ldd_rewrite_script to
	point to sed script for libc4 handling insertion for ix86, m68, SPARC.
	* sysdeps/unix/sysv/linux/i386/Makefile: Add rule to install lddlibc4.

1998-03-26 15:20  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* inet/rcmd.c (iruserok): Remain setuid to the local user
	while .rhosts is actually read, to make .rhosts-over-NFS work
	(PR libc/524).  Use iruserfopen() for security checks on both
	hosts.equiv and .rhosts.  General cleanup.
	(iruserfopen): New function, performs careful checking on
	hosts.equiv/.rhosts files.  Disallows all the old forbidden
	stuff plus hard links to files.

1998-03-29 09:26  Ulrich Drepper  <drepper@cygnus.com>

	* setjmp/tst-setjmp.c: Don't test __setjmp, test _setjmp instead.

1998-03-29 02:02  H.J. Lu  <hjl@gnu.org>

	* sysdeps/i386/i486/bits/string.h: Fix typos.

	* nss/nsswitch.c (__nss_lookup): Fix the bogus checking for
	"adjusted for next function".

1998-03-28 00:13  H.J. Lu  <hjl@gnu.org>

	* sysdeps/unix/sysv/linux/alpha/readdir.c (__readdir64): New
	strong alias.

	* sysdeps/unix/sysv/linux/alpha/syscalls.list (socket): Added.

	* libc.map (__ieee_get_fp_control, __ieee_set_fp_control):
	Added.  Used by libm.so on alpha.

1998-03-28  Thorsten Kukuk  <kukuk@vt.uni-paderborn.de>

	* intl/bindtextdom.c [_LIBC]: Define strdup only if not yet
	defined.

1998-03-27 07:29  H.J. Lu  <hjl@gnu.org>

	* Makerules (object-suffixes-for-rules): Add .oS only for
	building shared library.
	Add ranlib rule for nonshared library.
	(rmobjs): Fix typo.

	* Makeconfig (libtype.oS, CFLAGS-.oS, CPPFLAGS-.oS): Moved
	into for shared library only.
	(CPPFLAGS-.oS): Add -DPIC.
	(libtypes): Use $(object-suffixes-for-rules) instead of
	$(object-suffixes).

1998-03-28  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/Makefile (inhibit-stdio_lim): Compile
	and install lddlibc4.

1998-03-28 09:13  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* iconvdata/gap.pl: Gobble rest of line with a scalar, not a
	hash.
	* iconvdata/gaptab.pl: Likewise.
