Update.
1998-02-15 Ulrich Drepper <drepper@cygnus.com> * nss/nsswitch.c (__nss_lookup): Return 1 if this was the last module. * nss/getXXent_r.c: If no more module is found don't try to call setXXent functions but leave unsuccessfully. * malloc/obstack.h: Cleanups. * sysdeps/wordsize-32/stdint.h: New file. * sysdeps/wordsize-64/stdint.h: New file. * sysdeps/generic/stdint.h: New file. * sysdeps/wordsize-32/inttypes.h: Adopt to use stdint.h. * sysdeps/wordsize-64/inttypes.h: Likewise. * stdlib/Makefile (headers): Add stdint.h. 1998-02-03 Paul Eggert <eggert@twinsun.com> * malloc/obstack.h (PTR_INT_TYPE): Use __PTRDIFF_TYPE__ if available. 1998-02-13 17:59 Zack Weinberg <zack@rabi.phys.columbia.edu> * timezone: New directory. * time/README, time/africa, time/antarctica, time/asia, time/australasia, time/backward, time/checktab.awk, time/etcetera, time/europe, time/factory, time/ialloc.c, time/iso3166.tab, time/leapseconds, time/northamerica, time/pacificnew, time/private.h, time/scheck.c, time/solar87, time/solar88, time/solar89, time/southamerica, time/systemv, time/test-tz.c, time/tzfile.h, time/tzselect.ksh, time/yearistype, time/zdump.c, time/zic.c, time/zone.tab: Moved to timezone. * time/tzfile.c: Include tzfile.h from timezone subdir. * time/tzset.c: Likewise. * time/Makefile: Cut out all code relating to timezones... * timezone/Makefile: ...and paste it in here. * Makefile (subdirs): Add timezone. 1998-02-13 18:45 H.J. Lu <hjl@gnu.org> * libc.map (_sys_nerr): Added. * sysdeps/unix/sysv/linux/errlist.c (_sys_nerr): Make it versioned symbol. 1998-02-15 17:16 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/bits/socket.h: Define PF_KEY and pseudo_AF_KEY instead of pseudo_PF_KEY and AF_KEY. Reported by Craig Metz <cmetz@inner.net>. 1998-01-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * nss/nss_files/files-parse.c (LOOKUP_NAME_CASE): Use __strcasecmp instead of strcasecmp. * nss/nss_files/files-alias.c (get_next_alias): Likewise. * wctype/wctype.h (_ISwbit): Avoid warning with gcc before 2.8. 1998-02-15 16:55 Ulrich Drepper <drepper@cygnus.com> * socket/sys/socket.h (setsockopt): Make OPTVAL parameter const. Patch by Dean Gaudet <dgaudet@arctic.org>. 1998-02-15 16:53 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/Dist: Add getresgid.c and getresuid.c. 1998-02-15 10:49 Zack Weinberg <zack@rabi.phys.columbia.edu> * sysdeps/unix/sysv/linux/poll.c: If compiled against a kernel with no poll syscall, just include the BSD version. * sysdeps/unix/sysv/linux/getresuid.c: If compiled against a kernel without the syscall, include the stub version. * sysdeps/unix/sysv/linux/getresgid.c: Likewise. * sysdeps/generic/getresuid.c: New file. * sysdeps/generic/getresgid.c: New file. 1998-02-15 Ulrich Drepper <drepper@cygnus.com> * stdio-common/vfscanf.c: Correct last change a bit.
