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).
