1997-07-24 03:14 Ulrich Drepper <drepper@cygnus.com> * elf/dl-deps.c: Complete rewrite to handle DT_AUXILIARY correctly. * inet/Makefile (tests): Add htontest. * inet/htontest.c: New file. * inet/netinet/in.h: Cleanup optimization of ntoh/hton functions when they are no noops. * sysdeps/alpha/htonl.S: Don't define __ protected names. * sysdeps/alpha/htons.S: Likewise. * sysdeps/generic/htonl.c: Likewise. * sysdeps/generic/htons.c: Likewise. * sysdeps/i386/htonl.S: Likewise. * sysdeps/i386/htons.S: Likewise. * sysdeps/i386/i486/htonl.S: Likewise. * sysdeps/vax/htonl.s: Likewise. * sysdeps/vax/htons.s: Likewise. * string/Makefile (headers): Add byteswap.h and bits/byteswap.h. * string/byteswap.h: New file. * sysdeps/generic/bits/byteswap.h: New file. * sysdeps/i386/bits/byteswap.h: New file. * sysdeps/generic/bits/htontoh.h: Removed. * sysdeps/i386/bits/htontoh.h: Removed. * misc/search.h: General cleanup. Don't define reentrant hsearch functions uless __USE_GNU. * nss/nsswitch.c: Pretty print. * sunrpc/clnt_udp.c (clntudp_call): Initialize outlen to prevent warning. * sysdeps/unix/i386/sysdep.h (DO_CALL): Use lcall, binutils have been fixed meanwhile. Reported by Zack Weinberg <zack@rabi.phys.columbia.edu>. 1997-07-24 00:53 Philip Blundell <Philip.Blundell@pobox.com> * db/hash/hash.c (init_hash): Only use statbuf.st_blksize if it exists for this port. 1997-07-24 00:12 Philip Blundell <Philip.Blundell@pobox.com> * sysdeps/standalone/arm/bits/errno.h (ESTALE): Add. 1997-07-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/argp.texi (Argp Option Vectors): Use @minus, not @math, to format a proper minus sign. 1997-07-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/fpu/fraiseexcpt.c: Don't handle FE_INEXACT specially, the standard doesn't require it. * math/test-fenv.c (test_exceptions): Add IGNORE_INEXACT argument, if non-zero then don't test inexact flag. Callers changed. (set_single_exc): Ignore inexact flag if underflow or overflow exception is raised. 1997-07-23 05:10 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sys/fsuid.h: New file. Provided by Michael Deutschmann <ldeutsch@mail.netshop.net>. * sysdeps/unix/sysv/linux/Makefile (headers): Add sys/fsuid.h. * sysdeps/unix/sysv/linux/Dist: Add sys/fsuid.h. 1997-07-16 10:09 Fila Kolodny <fila@ibi.com> * resolv/gethnamaddr.c: Define MAXHOSTNAMELEN as 256, since RFC 1034 and 1035 state that a fully qualified domain name cannot exceed 255 octets in length. * resolv/nss_dns/dns-host.c: Likewise. 1997-07-22 09:54 H.J. Lu <hjl@gnu.ai.mit.edu> * inet/netinet/in.h (htons): Fix typos. * sysdeps/i386/bits/htontoh.h (__ntohs): Return the value. 1997-07-22 11:47 Ulrich Drepper <drepper@cygnus.com> * nss/nsswitch.c (nss_lookup_function): Include function.def, not functions.def. Patch by Klaus Espenlaub <kespenla@hydra.informatik.uni-ulm.de>.
