update from main archive 960921
Sun Sep 22 03:40:52 1996 Ulrich Drepper <drepper@cygnus.com> * resolv/resolv.h: Update to bind-4.9.5-T4B. * resolv/base64.c: Likewise. * resolv/res_debug.c: Likewise. * resolv/res_query.c: Likewise. * resolv/gethnamaddr.c: Likewise. * nss/nss_dns/dns-host.c: Likewise. * resolv/res_comp.c: Likewise. * resolv/res_send.c: Likewise. * resolv/arpa/nameser.h: Likewise. Attention: MAXDNAME is much higher now. * resolv/Banner: New file. * resolv/Makefile (distribute): Add Banner. Sat Sep 21 19:15:24 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/stub/getsysstats.c: New file. * sysdeps/unix/sysv/linux/getsysstats.c: New file. * misc/Makefile (headers): Add sys/sysinfo.h. (routines): Add getsysstats. * sysdeps/unix/sysv/linux/Makefile [$(subdir)==misc] (sysdep_headers): Remove sys/sysinfo.h. * sysdeps/generic/sys/sysinfo.h: New file. * sysdeps/unix/sysv/linux/sys/sysinfo.h: Add prototype for get_nprocs, get_phys_pages, and get_avphys_pages. * misc/Makefile (routines): Add mntent_r. * misc/mntent_r.c: New file. * misc/mntent.c: Remove all functions but getmntent and use __getmntent_r. * misc/mntent.h: Add prototype for __getmntent_r. * misc/fstab.c: Use __getmntent_r function instead of getmntent. This will not clobber the state in getmntent. * sysdeps/generic/confname.h: Add _SC_PROCESSORS_CONF, _SC_NPROCESSORS_ONLN, _SC_PHYS_PAGES, _SC_AVPHYS_PAGES, _SC_ATEXIT_MAX, and _SC_PASS_MAX. * sysdeps/stub/sysconf.c: Add handling _SC_PROCESSORS_CONF and _SC_NPROCESSORS_ONLN by calling __get_nprocs, _SC_PHYS_PAGES by calling __get_phys_pages, _SY_AVPHYS_PAGES by calling __get_avphys_pages, _SC_ATEXIT_MAX and _SC_PASS_MAX. * sysdeps/posix/sysconf.c: Likewise. * posix/getconf.c (vars): Add _NPROCESSORS_CONF, _NPROCESSORS_ONLN, _PHYS_PAGES, _AVPHYS_PAGES, ATEXIT_MAX, and PASS_MAX entries. Sat Sep 21 05:20:36 1996 Ulrich Drepper <drepper@cygnus.com> * version.h (VERSION): Bump to 1.95. * Make-dist (+tsrcs): Don't filter out files in subdirs which match files in the sysdeps hierachy (welcome back, sys/syscall.h!). * resolv/Makefile (libresolv-routines): Remove getnetnamad. Sat Sep 21 03:00:19 1996 Ulrich Drepper <drepper@cygnus.com> * locale/loadlocale.c (_nl_free_locale): Remove function. * locale/localeinfo.h: Remove prototype for _nl_free_locale. * locale/setlocale.c (setlocale): Don't free locale data of categories which succeeded to load after a wrong or missing data file was observed. * locale/setlocale (setlocale): Initialize NEWNAME correctly so that it works even when the locale data is not used. * stdlib/random_r.c: Fix typo in comment. * stdlib/drand48-iter.c: Likewise. * stdlib/drand48.c: Likewise. * stdlib/erand48.c: Likewise. * stdlib/jrand48.c: Likewise. * stdlib/lcong48.c: Likewise. * stdlib/lrand48.c: Likewise. * stdlib/mrand48.c: Likewise. * stdlib/nrand48.c: Likewise. * stdlib/random.c: Likewise. * stdlib/seed48.c: Likewise. * stdlib/srand48.c: Likewise. * misc/search.h: Likewise. * misc/hsearch.c: Likewise. * misc/hsearch_r.c: Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep.S (__errno_location): Thu Sep 19 23:36:19 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * hurd/hurdinit.c (__libc_argv): Provide common decl.
