Thu Sep 12 03:35:27 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/i386/Dist: Remove init-first.h. * sysdeps/unix/sysv/linux/m68k/Dist: Likewise. * sysdeps/unix/sysv/linux/Dist: Add init-first.h. 1996-09-11 Paul Eggert <eggert@twinsun.com> * strftime.c (strftime): Handle E and O modifiers, required for POSIX.2 and XPG4. Don't use sprintf to format numbers; this way, we can handle time_t correctly regardless of whether it's signed. Don't dump core if format ends in %. In default %c format, use %e instead of %d, for POSIX.2 compatibility. For %z: Use tm_gmtoff if available. Output nothing if tm_isdst is negative. Output correct value even if arg is 1969-12-31 23:59:59 UTC. Don't assume that UTC offset is less than 24 hours; Posix requires support for 24 hours, and there's no point limiting it at all. (HAVE_TM_GMTOFF, TYPE_SIGNED, INT_STRLEN_BOUND): New macros. (CHAR_BIT): Define if <limits.h> doesn't. (tm_diff): New function. (fmt, <stdio.h>): Remove; no longer used. Thu Sep 12 02:21:44 1996 Ulrich Drepper <drepper@cygnus.com> * db/Makefile: Add extra-libs-others variable so that shared library is built in `others' pass. * elf/Makefile: Likewise. * math/Makefile: Likewise. * resolv/Makefile: Likewise. * Makefile (generated): Add version.info.h. * time/checktab.awk: New file. From ADO 96k. * time/iso3166.tab: Likewise. * time/tzselect.ksh: Likewise. * time/zone.tab: Likewise. * stdio-common/vfprintf.c: Correct cleanup registration. We cannot use a macro 1996-09-11 Paul Eggert <eggert@twinsun.com> * time/time.h (tm_gmtoff, tm_zone): Prefix with `__' unless __USE_BSD; this is required for ANSI C compatibility. * manual/time.texi: Replace GMT by UTC, daylight savings by daylight saving, timezone by time zone. Rewrite description of %V to match ISO 8601. Fix TZ Posix string example for US Eastern time. Explain tzname[1] when DST isn't used. Explain tzname when multiple abbreviations used (e.g. EST/EWT/EDT). Explain that timezone's sign is opposite from tm_gmtoff, and that timezone lacks DST adjustment whereas tm_gmtoff has it. Deprecate tzname and timezone. Tue Sep 10 14:46:16 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> Implement Roland McGrath's idea of how to put an .interp into shared libraries. * interp.c: New file. * Makerules (interp-obj): New object, linked into every shared library. (common-generated): Add interp.so. (CFLAGS-interp.c): Pass name of interpreter. Tue Sep 10 21:09:35 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * db/Makefile: Fix typo. Tue Sep 10 19:29:53 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * nss/db-Makefile ($(VAR_DB)/passwd.db): Look for multiple occurences of the same uid, and only generate a mapping for the first one. Tue Sep 10 03:14:59 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/system.c: New file, to override sysdeps/unix/system.c. Tue Sep 10 15:05:40 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makefile (before-compile): Add version-info.h, needed to build version.d. Tue Sep 10 14:14:33 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/m68k/sysdep.S: Remove check for EWOULDBLOCK, never true on Linux. (__errno_location): New function. [_LIBC_REENTRANT]: Set errno using __errno_location function. * sysdeps/unix/sysv/linux/m68k/sysdep.h [PIC]: Add second syscall_error handler for reentrant libc. Tue Sep 10 13:27:49 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/Makefile (extra-objs): Add eval.so to get dependencies. Wed Sep 11 04:40:57 1996 Ulrich Drepper <drepper@cygnus.com> * time/tzset.c (__tzname_cur_max): Use type `size_t' to avoid warning. * time/tzfile.c (compute_tzname_max): Likewise.
