From 7cc27f440c2f709fda63af7ecb3747deeeb799f0 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 10 Feb 1997 03:19:57 +0000 Subject: update from main archive 970209 1997-02-09 02:59 Ulrich Drepper * version.h (VERSION): Bump to 2.0.2. * posix/Makefile (routines): Add getopt_init. * posix/getopt.c: Don't get environment variable with nonoption flags here. Depend on __getopt_nonoption_flags variable filled somewhere else. This is necessary since the variable must be removed even when getopt isn't used in case exec(2) gets called. * posix/getopt_init.c: New file. Initialize __getopt_nonoption_flags and remove environment variable. * sysdeps/i386/init-first.c: Call __getopt_clean_environment. * sysdeps/mach/hurd/i386/init-first.c: Likewise. * sysdeps/stub/init-first.c: Likewise. * sysdeps/unix/sysv/linux/init-first.c: Likewise. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Recognize AT_PAGESZ entry in auxiliary vector and store value in _dl_pagesize. * sysdeps/generic/crypt-entry.h: Return EOPNOTSUPP when DES encryption is wanted. * libio/vsnprintf.c: If MAXLEN is 0 return 0. * stdio/vsnprintf.c: Likewise. Reported by Philip Blundell . 1997-02-07 17:43 Ulrich Drepper * sysdeps/generic/sysd-stdio.c: Include . Change PTR to void *. * sysdeps/posix/vdprintf.c: Change PTR to void *. Reported by Brian Oxley . 1997-02-07 17:41 Philip Blundell * sysdeps/unix/sysv/linux/socketbits.h: Fix typo. 1997-02-06 13:49 Andreas Schwab * rellns-sh: No need to check for existance of first parameter. 1997-02-06 14:50 Andreas Schwab * sysdeps/posix/getcwd.c (__getcwd): Fix resource leaks. Reported by David Holland . 1997-02-06 14:38 Andreas Schwab * sunrpc/clnt_tcp.c (readtcp): Pass copy of timeout value to select, in case it is modified by the latter. * sunrpc/clnt_udp.c (clntudp_call): Likewise. * sunrpc/pmap_rmt.c (clnt_broadcast): Likewise. * sunrpc/svc_tcp.c (readtcp): Likewise. * sunrpc/svc_authux.c (_svcauth_unix): Fix type of area_gids array. * sunrpc/authuxprot.c (xdr_authunix_parms): Check size of uid_t and gid_t. * sunrpc/auth_unix.c (authunix_validate): Fix type of second argument. 1997-02-06 14:29 Andreas Schwab * elf/Makefile (extra-objs): Don't zap previous value. * Makefile (before-compile): Likewise. Don't add gnu/lib-names.h twice. 1997-02-06 14:19 Andreas Schwab * sysdeps/unix/sysv/linux/m68k/brk.c: Add workaround for braindamage (sigh!). 1997-02-06 17:10 Jim Meyering * manual/memory.texi: Correct `copystring' example for obstacks. 1997-02-06 14:10 Ulrich Drepper * Makeconfig: Don't use [:lower:] and [:upper:] in tr since old GNU tr don't grok it. 1997-02-03 21:13 Andreas Schwab * sysdeps/unix/sysv/linux/socketbits.h [__GNUC__<2] (struct cmsghdr): Don't use GNU C extensions. (CMSG_DATA): Use portable definition. 1997-02-05 05:58 Ulrich Drepper * elf/ldd.bash.in: Add test for read permission and print appropriate message. Change warning and error messages to print "ldd: " at start. * elf/ldd.sh.in: Likewise. * stdlib/Makefile (routines): Add atoll. * stdlib/atoll.c: New file. * stdlib/stdlib.h: Add prototype and optimization for atoll. * stdlib/a64l.c: Update copyright. * stdlib/abs.c: Likewise. * stdlib/atof.c: Likewise. * stdlib/atoi.c: Likewise. * stdlib/atol.c: Likewise. * stdlib/bsearch.c: Likewise. * stdlib/exit.c: Likewise. * stdlib/fpioconst.c: Likewise. * stdlib/fpioconst.h: Likewise. * stdlib/jrand48.c: Likewise. * stdlib/jrand48_r.c: Likewise. * stdlib/labs.c: Likewise. * stdlib/lcong48.c: Likewise. * stdlib/lcong48_r.c: Likewise. * stdlib/llabs.c: Likewise. * stdlib/lrand48.c: Likewise. * stdlib/lrand48_r.c: Likewise. * stdlib/mblen.c: Likewise. * stdlib/mbstowcs.c: Likewise. * stdlib/mbtowc.c: Likewise. * stdlib/mp_clz_tab.c: Likewise. * stdlib/mrand48.c: Likewise. * stdlib/mrand48_r.c: Likewise. * stdlib/msort.c: Likewise. * stdlib/nrand48.c: Likewise. * stdlib/nrand48_r.c: Likewise. * stdlib/qsort.c: Likewise. * stdlib/rpmatch.c: Likewise. * stdlib/seed48.c: Likewise. * stdlib/seed48_r.c: Likewise. * stdlib/srand48.c: Likewise. * stdlib/srand48_r.c: Likewise. * stdlib/strtod.c: Likewise. * stdlib/wcstombs.c: Likewise. * stdlib/wctomb.c: Likewise. 1997-02-05 05:08 Ulrich Drepper * stdlib/mp_clz_tab.c (__clz_tab): Follow change in GMP and define as const. 1997-02-04 23:57 Fila Kolodny * sysdeps/unix/sysv/linux/socketbits.h: Define __need_NULL before including . 1997-02-03 20:01 H.J.
