1997-05-25 03:00 Ulrich Drepper <drepper@cygnus.com> * elf/dynamic-link.h (_dl_verbose): New variable, declare. * elf/rtld.c (_dl_verbose): New variable, define. (dl_main): Define _dl-verbose based on DL_WARN environment variable. * sysdeps/i386/dl-machine.h (elf_machine_rel): Print warning about changed size in copy relocation only if symbol in shared object is larger or _dl_verbose is nonzero. * sysdeps/m68k/dl-machine.h (elf_machine_rel): Likewise. * sysdeps/powerpc/dl-machine.h (elf_machine_rel): Likewise. * sysdeps/sparc/dl-machine.h (elf_machine_rel): Likewise. * nis/nss_nis/nis-ethers.c: Don't use relative include paths, use <...>. * nis/nss_nis/nis-grp.c: Likewise. * nis/nss_nis/nis-hosts.c: Likewise. * nis/nss_nis/nis-network.c: Likewise. * nis/nss_nis/nis-proto.c: Likewise. * nis/nss_nis/nis-pwd.c: Likewise. * nis/nss_nis/nis-rpc.c: Likewise. * nis/nss_nis/nis-spwd.c: Likewise. * sysdeps/unix/sysv/sysd-stdio.c: Likewise. * wcsmbs/wcscoll.c: Likewise. * wcsmbs/wcstod.c: Likewise. * wcsmbs/wcstof.c: Likewise. * wcsmbs/wcstol.c: Likewise. * wcsmbs/wcstold.c: Likewise. * wcsmbs/wcsxfrm.c: Likewise. Reported by Zack Weinberg <zack@rabi.phys.columbia.edu>. * time/strftime.c: Implement # flag which changes case of output for %a, %b, %B, %p, and %Z format. When printing numbers, the given field width is always respected. This means that padding happens only up to the given width. Proposed by Stephen Gildea <gildea@intouchsys.com>. 1997-05-25 00:44 Ulrich Drepper <drepper@cygnus.com> * sysdeps/i386/fpu/__math.h (logb): Fix thinko, reverse output values. Reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>. 1997-05-24 21:03 Philip Blundell <pjb27@cam.ac.uk> * db/btree/bt_open.c (__bt_open): Only try to use st_blksize (from struct stat) if it exists for this port. 1997-05-24 20:34 Philip Blundell <pjb27@cam.ac.uk> * sysdeps/standalone/arm/errnos.h: Add EPERM. 1997-05-23 16:28 Philip Blundell <phil@kings-cross.london.uk.eu.org> * linewrap.h: New file, needed to compile argp without libio. 1997-05-24 11:59 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/stdio.texi (Formatted Messages): Corrected some typos. 1997-05-24 11:58 Philip Blundell <pjb27@cam.ac.uk> * sysdeps/stub/start.c: Fix typo.
