Wed Oct 9 00:30:33 1996 Ulrich Drepper <drepper@cygnus.com> * inet/getnetgrent_r.c: Correct netgroup implementation. A specification of a netgroup can also name another netgroup. * nss/nss_files/files-netgrp.c: Likewise. * inet/netgroup.h: Add fields to hold additional information. Tue Oct 8 21:51:14 1996 Arnold D. Robbins <arnold@skeeve.atl.ga.us> * posix/getopt.c: Implement POSIX -W option handling. When the option string contains "W;" -W foo is handled like --foo. Tue Oct 8 12:27:26 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/i386/clone.S: Define _ERRNO_H before inclusing <errnos.h> so we really get error symbols defined. * sysdeps/unix/sysv/linux/m68k/clone.S: Likewise. * sysdeps/unix/sysv/linux/alpha/clone.S: Likewise. * sunrpc/auth_unix.c (authunix_create_default): Don't use fixed size array for getgroups call. Instead get maximal number via sysconf. But discard list to NGRPS elements before calling XDR function since Sun's code cannot handle longer lists. Based on a patch by Thorsten Kukuk <kukuk@weber.uni-paderborn.de>. * sysdeps/stub/e_j0l.c: Define y0l as well. * sysdeps/stub/e_j1l.c: Define y1l as well. * sysdeps/stub/e_jnl.c: Define ynl as well. * posix/unistd.h: Correct prototype for execlp. * sysdeps/unix/sysv/linux/posix_opt.h: Define _POSIX_NO_TRUNC. Mon Oct 7 22:18:03 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makeconfig (sysdep-library-path): New variable. (built-program-cmd): Use it here to properly build a colon separated library path. Mon Oct 7 22:11:55 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * crypt/md5-crypt.c (md5_crypt_r): Add missing parens around & within comparison. Fix comments. (md5_crypt): Fix comment. Tue Oct 8 05:10:49 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/errnos.h: Only include <linux/errnos.h> when _ERRNO_H is defined. [!_ERRNO_H && __need_Emath]: Define value for EDOM and ERANGE. Should there ever be a Linux port where the numeric values are not 33 and 34 this file must change. Mon Oct 7 13:54:04 1996 Ulrich Drepper <drepper@cygnus.com> * libio/iofgets.c (_IO_fgets): Use _IO_flockfile instead of __flockfile. Mon Oct 7 11:01:45 1996 Andreas Jaeger <aj@arthur.pfalz.de> * string/tst-strlen.c (main): Provide prototype. * malloc/mallocbug.c: Likewise. * io/test-utime.c: Likewise. * sysdeps/generic/crypt-entry.c: Correct typo. Mon Oct 7 13:42:20 1996 Ulrich Drepper <drepper@cygnus.com> * elf/dl-open.c (_dl_open): Check against _dl_sysdep_start to test for libc.a. Checking _DYNAMIC is of no worth here. Suggested by Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>. * nss/nss_files/files-parse.c: Define LOOKUP_NAME even if EXTERN_PARSER is defined. Sat Oct 5 17:05:36 1996 Andreas Jaeger <aj@arthur.pfalz.de> * Rules (dep-dummy-lib): Correct prototype for __dummy__. * crypt/md5-crypt.c: Fix typos in comments. * gmon/gmon.c: Provide prototypes. * db/makedb.c: Likewise. * locale/programs/xmalloc.c: Likewise. * stdio-common/bug11.c (main): Likewise. * stdio-common/bug7.c (main): Likewise. * stdio-common/bug8.c (main): Likewise. * stdio-common/bug9.c (main): Likewise. * stdio-common/scanf1.c (main): Likewise. * stdio-common/scanf2.c (main): Likewise. * stdio-common/scanf5.c (main): Likewise. * stdio-common/scanf6.c (main): Likewise. * stdio-common/scanf7.c (main): Likewise. * stdio-common/scanf8.c (main): Likewise. * stdio-common/temptest.c (main): Likewise. * stdio-common/test-fwrite.c (main): Likewise. * stdio-common/tst-printf.c: Likewise. * stdio-common/tstdiomisc.c: Likewise. * stdio-common/tstgetln.c (main): Likewise. * stdlib/testmb.c (main): Likewise. * stdio-common/scanf4.c (main): Correct prototype, remove unused variable n. * stdio-common/scanf3.c (main): Correct prototype, change declaration of s to reduce warnings. * stdio-common/bug10.c (main): Likewise. * stdio-common/tfformat.c: Provide prototype, remove unused reference to dump_stats, add braces in sprint_doubles. * stdio-common/tiformat.c: Likewise. * stdio-common/test_rdwr.c (main): Parameter `where' is long in printf call. Mon Oct 7 14:04:26 1996 NIIBE Yutaka <gniibe@mri.co.jp> * sysdeps/unix/sysv/linux/sys/soundcard.h: Fix typo. * shadow/putspent.c: Don't write colon after flag field. * sysdeps/unix/sysv/linux/net/if_ppp.h: New file. Wrapper around kernel header. * sysdeps/unix/sysv/linux/net/ppp-comp.h: Likewise. * sysdeps/unix/sysv/linux/net/ppp_defs.h: Likewise. * sysdeps/unix/sysv/linux/Dist: Mention new files. Mon Oct 7 00:58:19 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/i386/i586/strchr.S: Correct handling of first bytes to get pointer aligned. Reported by Matthias Urlichs <smurf@noris.de>. * sysdeps/posix/euidaccess.c [_LIBC]: Avoid calling get?id functions by using __libc_enable_secure variable. * sysdeps/libm-i387/s_copysignl.S: Correct loading of return value.
