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.
