update from main archive 970209cvs/libc-970210
1997-02-09 02:59 Ulrich Drepper <drepper@cygnus.com> * 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 <pjb27@cam.ac.uk>. 1997-02-07 17:43 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/sysd-stdio.c: Include <errno.h>. Change PTR to void *. * sysdeps/posix/vdprintf.c: Change PTR to void *. Reported by Brian Oxley <boxley%dev.cm.ssb.com@clipper.ssb.com>. 1997-02-07 17:41 Philip Blundell <pjb27@cam.ac.uk> * sysdeps/unix/sysv/linux/socketbits.h: Fix typo. 1997-02-06 13:49 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * rellns-sh: No need to check for existance of first parameter. 1997-02-06 14:50 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/posix/getcwd.c (__getcwd): Fix resource leaks. Reported by David Holland <dholland@eecs.harvard.edu>. 1997-02-06 14:38 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * 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 <schwab@issan.informatik.uni-dortmund.de> * 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 <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/m68k/brk.c: Add workaround for braindamage (sigh!). 1997-02-06 17:10 Jim Meyering <meyering@asic.sc.ti.com> * manual/memory.texi: Correct `copystring' example for obstacks. 1997-02-06 14:10 Ulrich Drepper <drepper@cygnus.com> * Makeconfig: Don't use [:lower:] and [:upper:] in tr since old GNU tr don't grok it. 1997-02-03 21:13 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * 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 <drepper@cygnus.com> * elf/ldd.bash.in: Add test for read permission and print appropriate message.
