* posix/regcomp.c (analyze_tree): Always call calc_epsdest.
(calc_inveclosure): Use re_node_set_insert_last.
(parse_dup_op): Lower X{1,5} to (X(X(X(XX?)?)?)?)?
rather than X?X?X?X?X?.

included by kernel headers and undo its settings if already
included. Define _ABIO32, _ABIN32 and _ABI64 if missing and use
them to define _MIPS_SIM_ABI32, _MIPS_SIM_NABI32 and

* nss/nss_files/files-XXX.c (internal_getent): If parse_line returned
-1, also do H_ERRNO_SET (NETDB_INTERNAL).
2004-11-20 Jakub Jelinek <jakub@redhat.com>

comma at the end of enum if __USE_BSD is not defined.

corruption.

[BZ #544]
* posix/regex.h (RE_NO_SUB): New define.
* posix/regex_internal.h (OP_DELETED_SUBEXP): New.
(re_dfa_t): Add subexp_map.
* posix/regcomp.c (struct subexp_optimize): New type.
(optimize_subexps): New routine.
(re_compile_internal): Call it.
(re_compile_pattern): Set preg->no_sub to 1 if RE_NO_SUB.
(free_dfa_content): Free subexp_map.
(calc_inveclosure, calc_eclosure): Skip OP_DELETED_SUBEXP
nodes.
* posix/regexec.c (re_search_internal): If subexp_map
is not NULL, duplicate registers as needed.
* posix/Makefile: Add rules to build and run tst-regex2.
* posix/tst-regex2.c: New test.
* posix/rxspencer/tests: Fix last two tests (\0 -> \1).
Add some new tests for nested subexpressions.
2004-11-15 Jakub Jelinek <jakub@redhat.com>
* posix/bug-regex24.c: Include string.h.
* nis/nis_clone_obj.c (nis_clone_object): Rename out3 label to out2
and out2 to out. Remove out label. Formatting.
2004-11-15 Ulrich Drepper <drepper@redhat.com>
* include/stdio.h: Do not mark __libc_message as noreturn.
* sysdeps/unix/sysv/linux/libc_fatal.c (__libc_fatal): Add loop to
fool gcc. Include <stdbool.h>.
* sysdeps/posix/libc_fatal.c (__libc_fatal): Add loop to fool gcc.
(__libc_message): Fix typo.
2004-11-13 Ulrich Drepper <drepper@redhat.com>
* malloc/malloc.c (malloc_state): stat_lock_* elements need only
be defined if THREAD_STATS is defined. Remove pad0_ since it does
not align with cache line sizes in general anyway.
2004-11-13 Jakub Jelinek <jakub@redhat.com>
* elf/rtld.c (print_statistics): Avoid segfaults if not all namespaces
are used. Fix computation of num_relative_relocations on RELA
architectures other than IA-64 and Alpha.
2004-11-13 Ulrich Drepper <drepper@redhat.com>
* malloc/malloc.c (_int_free): Use munmap_chunk for handling
mmaped memory.
2004-11-12 Ulrich Drepper <drepper@redhat.com>
* sysdeps/unix/sysv/linux/libc_fatal.c: Add new function __libc_message
which performs the printing and simple format string handling. The
string is written to tty, stderr, syslog in this order, stopping after
the first successful output.
(__libc_fatal): Call __libc_message.
* include/stdio.h: Declare __libc_message.
* malloc/malloc.c (malloc_printerr): Use __libc_message.
* debug/chk_fail.c: Also print message with __libc_message.
* debug/test-strcpy_chk.c: Ensure that debug messages are not printed
to the terminal or stderr.
* debug/tst-chk1.c: Likewise.
* posix/Makefile: Remove gpl2lgpl variable.
2004-11-12 Ulrich Drepper <drepper@redhat.com>
* posix/Makefile (tests): Add bug-regex24.
* posix/bug-regex24.c: New file.
2004-11-12 Paolo Bonzini <bonzini@gnu.org>
* posix/regexec.c (check_dst_limits_calc_pos_1): Use the map to
cut recursive paths. Make exit condition more precise.
(match_ctx_add_entry): Initialize the map.
* posix/regex_internal.h (struct re_backref_cache_entry): Add a map of
reachable subexpression nodes from each backreference cache entry.
2004-11-09 Paul Eggert <eggert@cs.ucla.edu.
[BZ #535]
* time/difftime.c: Fix a double-rounding bug on hosts with
64-bit time_t and long double being IEEE double. Also, port
to more valid C99 hosts, even those that have padding bits.
Don't include <values.h> since it is marked as an obsolescent
interface. Include <limits.h>, <float.h>, and <stdint.h> instead.
(TYPE_BITS, TYPE_FLOATING, TYPE_SIGNED): New macros.
(subtract): New static function, that works correctly without
double-rounding, even on hosts with 64-bit time_t. Also cater
to hosts with padding bits.
(__difftime): Use it. Use DBL_MANT_DIG and LDBL_MANT_DIG to
determine whether floating types are wide enough: the old
test (which used sizeof) could in theory report the wrong results
on hosts with padding bits in floating-point values.
2004-11-11 Simon Josefsson <jas@extundo.com>
[BZ #542]
* sysdeps/generic/strtok_r.c [HAVE_CONFIG_H]: Include config.h.
[!_LIBC]: Include strtok_r.h (in gnulib), map __strtok_r to
strtok_r and __rawmemchr to strch.
(__strtok_r): Use C89 prototype.
[weak_alias]: Move calls to libc_hidden_def and weak_alias into
this #ifdef.
