+
+2004-05-14 Bruno Haible <bruno@clisp.org>
+
+ * vasnprintf.c (VASNPRINTF): Correctly handle the case of a precision
+ that consists of a '.' followed by an empty digit string.
+ Patch by Tor Lillqvist <tml@iki.fi>.
+
+2004-05-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ Port obstack to the AS/400, where pointers are 16 bytes wide and
+ you cannot cast an integer to a valid pointer. This patch is
+ currently waiting to be integrated into glibc; see
+ <http://sources.redhat.com/ml/libc-alpha/2004-05/msg00073.html>.
+
+ * obstack.h (__PTR_TO_INT, __INT_TO_PTR): Remove.
+ All uses of __INT_TO_PTR (PTR_TO_INT ...) replaced by __PTR_ALIGN.
+ (__BPTR_ALIGN, __PTR_ALIGN): New macros.
+ (struct obstack): temp member is now a union of a pointer and
+ an integer, instead of an integer. All integer uses changed.
+ This does not affect the physical layout of struct obstack,
+ except on hosts (like the AS/400) where the size or alignment of
+ void * is greater than that of ptrdiff_t.
+ (obstack_finish) [! (defined __GNUC__ && defined __STDC__ &&
+ __STDC__)]: Store temporary in pointer member of union, not
+ integer member.
+ * obstack.c: Include <stddef.h>, for offsetof.
+ (struct fooalign): Remove; it doesn't need a name.
+ (union fooround): Change double to long double, and add void *.
+ (DEFAULT_ALIGNMENT): Use offsetof to compute.
+ (DEFAULT_ALIGNMENT, DEFAULT_ROUNDING): Now an enum constant,
+ not a macro. Hence the values are always int; so remove all
+ casts-to-int in uses.
+
+2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
+ Derek Price <derek@ximbiot.com>
+
+ * alloca.c: Include <alloca.h>, to get our interface.
+ * alloca_.h: Use __alloca on AIX, so that we don't have to
+ include <alloca.h> first. Use C89 prototype for alloca; this
+ requires including <stddef.h> for size_t. Use extern "C" if C++.
+ Use #elif for simplicity, since we can assume C89 now.
+ Don't try to source the system alloca.h since it will not be found
+ and to prevent recursively including its replacement.
+ * fnmatch.c: Include <alloca.h> instead of opencoding.
+ * lib/regex.c: Likewise.
+
+2004-05-16 Derek Price <derek@ximbiot.com>
+ Paul Eggert <eggert@cs.ucla.edu>
+
+ getline cleanup. This changes the getndelim2 API: both order of
+ arguments, and meaning of delim2 (now uses EOF, not 0, to indicate
+ no delimiter).
+
+ * getline.c: Don't include stddef.h or stdio.h, since our
+ interface does that.
+ (getline): Always use getdelim, so that we don't have two
+ copies of this code.
+ * getndelim2.c: Include <limits.h>, <inttypes.h>, <stdint.h>
+ if available.
+ (PTRDIFF_MAX, SIZE_MAX, SSIZE_MAX): Define if not defined.
+ (GETNDELIM2_MAXIMUM): New macro.
+ (getndelim2): Reorder arguments. delim==EOF now means no delimiter,
+ instead of the old practice of delim2==0. All callers changed.
+ Return -1 on overflow, instead of returning junk.
+ Do not set *linesize unless allocation succeeds.
+ * getndelim2.h: Do not include stddef.h; no longer needed, now
+ that we include sys/types.h.
+ * getnline.h: Likewise.
+ * getndelim2.h (GETNLINE_NO_LIMIT): New macro.
+ (getndelim2): Reorder arguments.
+ * getnline.c (getnline, getndelim):
+ Don't discard the NMAX argument.
+ (getnline): Invoke getndelim, to avoid code duplication.
+ * getnline.h (GETNLINE_NO_LIMIT): New macro, used instead
+ of (size_t) -1 by callers of the getnline family.
+
+2004-05-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * nanosleep.c (suspended): Change its type from int to
+ sig_atomic_t volatile.
+ (first_call): Make it private to rpl_nanosleep, and have it
+ be zero initially as that's a bit faster.
+ (my_usleep): Round up fractional times instead of truncating them,
+ as this is the usual meaning for 'sleep'.
+
+ * gettime.c (gettime): Fall back on `time' if `gettimeofday'
+ doesn't work.
+ * settime.c: Include <unistd.h>, for stime (on Solaris 8, anyway).
+ (ENOSYS): Define if not defined.
+ (settime): Fall back on stime if it exists and settimeofday fails.
+ But don't bother with fallbacks if a method fails with errno == EPERM.
+
+2004-05-11 Jim Meyering <jim@meyering.net>
+
+ Prior to this change, the save_cwd caller required read access to the
+ current directory on most systems (ones with the fchdir function).
+
+ * save-cwd.c (save_cwd) [HAVE_FCHDIR]: If opening `.' read-only
+ fails, try write-only, and finally, resort to using xgetcwd.

+
+2004-03-30 Paul Eggert <eggert@twinsun.com>

+ Merge from coreutils.
+
+ * imaxtostr.c, inttostr.c, inttostr.h, offtostr.c, umaxtostr.c:
+ New files.
+
+ * getdate.h: Include stdbool.h, and timespec.h instead of
+ the usual <time.h> dance.
+ (get_date): Change signature to support fractional time stamps.
+ All callers changed.
+ * getdate.y: Include "getdate.h" first, as we can now
+ assume C89 and don't need to worry about 'const'.
+ Similarly, include "unlocked-io.h" near start, not in middle.
+ Include <limits.h>.
+ (textint.value): Use long int rather than int.
+ (textint.digits): Use size_t rather than int.
+ (BILLION, LOG10_BILLION): New constants.
+ (parser_control): New member rel_ns. Members day_ordinal,
+ time_zone, month, day, hour, minutes, rel_year, rel_month,
+ rel_day, rel_hour, rel_minutes, rel_seconds
+ are now long int, not int. Member seconds is now struct timespec,
+ not int. New member timespec_seen. Members dates_seen, days_seen,
+ local_zones_seen, rels_seen, times_seen, zones_seen are now size_t,
+ not int.
+ (%union.intval): Now long int, not int.
+ New member timespec.
+ (tSDECIMAL_NUMBER, tUDECIMAL_NUMBER): New tokens.
+ (seconds, signed_seconds, unsigned_seconds): New nonterminals.
+ (spec): Now is a timespec or an item list.
+ (timespec, items): New nonterminals.
+ (time, rel, relunit, number, get_date):
+ Add support for fractional seconds.
+ (time): Fix bug: seconds weren't cleared in "00:00 +0000" syntax.
+ (gmtime, localtime, mktime): Remove decls; not needed with C89.
+ (to_hour): First arg is now long int, not int.
+ (to_year): Returns long int, not int.
+ Don't treat year -70 like 70.
+ (tm_diff): Returns long int, not int.

+ (get_date): Make pointers 'const' if possible.
+ Use more-portable code to detect integer overflow.
+ (main) [TEST]: Adjust to above changes. Test for localtime failure.
+ Don't use ctime; it's not reliable if the year has >4 digits.
+
+ * human.c (humblock): Inspect BLOCKSIZE if BLOCK_SIZE isn't set.
+ This is for compatibility with BSD.
+
+ * timespec.h (ST_TIME_CMP_NS, ST_TIME_CMP): Define.
+ (ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise.
+ From coreutils' system.h.
+
+ * userspec.c: Don't include "posixver.h".
+ (parse_user_spec): Fall back on USER.GROUP parsing, regardless
+ of POSIX version, as POSIX 1003.1-2001 allows that behavior as a
+ compatible extension. Simplify code by removing a boolean int
+ that was always nonzero if a string was nonnull.

+ * xalloc.h: Include limits.h. Assume SIZE_MAX and PTRDIFF_MAX are
+ defined.
+
+2003-11-10 Paul Eggert <eggert@twinsun.com>
+
+ * xalloc.h (xalloc_oversized): [! (defined PTRDIFF_MAX &&
+ PTRDIFF_MAX < SIZE_MAX)]: Fix off-by-one error that would have
+ rejected some allocations of exactly SIZE_MAX - 2 bytes.
+ From Bruno Haible.
+ [defined PTRDIFF_MAX && PTRDIFF_MAX < SIZE_MAX]: Use SIZE_MAX,
+ not (size_t) -1, since it's defined here.
+
+2003-11-06 Paul Eggert <eggert@twinsun.com>
+
+ * xalloc.h [HAVE_STDINT_H]: Include <stdint.h>.
+ (xalloc_oversized) [! (PTRDIFF_MAX < SIZE_MAX)]:
+ Reject sizes of exactly SIZE_MAX bytes.
+ * xreadlink.c: Include "xalloc.h" before checking whether SIZE_MAX
+ is defined, since "xalloc.h" now defines SIZE_MAX on modern hosts.
+
+2003-11-05 Bruno Haible <bruno@clisp.org>
+
+ * xsize.h: Include limits.h, to avoid a possible collision with
+ SIZE_MAX defined in <limits.h> on Solaris.
+
+2003-11-04 Bruno Haible <bruno@clisp.org>
+
+ * xsize.h: New file.
+ * linebreak.c: Include xsize.h.
+ (mbs_possible_linebreaks, mbs_width_linebreaks): Check malloc()
+ argument for overflow.
+ Suggested by Paul Eggert.
+
+2003-10-31 Bruno Haible <bruno@clisp.org>
+
+ * wait-process.c (wait_process): Use waitid with WNOWAIT if available,
+ to avoid (extremely rare) race condition.
+ Suggested by Paul Eggert.
+
+2003-11-03 Jim Meyering <jim@meyering.net>
+
+ * userspec.c: Include "userspec.h".
+ * userspec.h: New file.
+
+2003-10-31 Paul Eggert <eggert@twinsun.com>
+
+ * mountlist.h (struct mount_entry.me_type_malloced): New member.
+ * mountlist.c (SIZE_MAX): Define if not defined already.
+ (read_filesystem_list): Set and use me_type_malloced.
+ Use "sizeof *me" rather than "sizeof (struct mount_entry)" (or
+ whatever the type happens to be), for brevity and consistency.
+ Check for size calculation overflow on Alphas running OSF/1.
+
+2003-10-31 Jim Meyering <jim@meyering.net>
+
+ * hash.c: Include "xalloc.h" for use of xalloc_oversized.
+
+ * linebuffer.c: Include <string.h> for declaration of memset.
+
+2003-10-30 Paul Eggert <eggert@twinsun.com>
+ Bruno Haible <bruno@clisp.org>
+
+ * vasprintf.c: Include <limits.h>, <stdlib.h>.
+ (vasprintf): Fail if the resulting length doesn't fit in an 'int'.
+
+2003-10-29 Paul Eggert <eggert@twinsun.com>
+
+ * xalloc.h (xalloc_oversized): Now a macro, not a function,
+ so that it works even if SIZE_MAX < N. Do not include <stdbool.h>;
+ no longer needed.
+ * quotearg.c (quotearg_n_options): Use it.
+ * group-member.c: Include <stdbool.h>.
+ (free_group_info): Arg is now const *; don't free arg.
+ (get_group_info): Now returns bool and accepts struct group_info *,
+ rather than returning a malloc'ed struct group_info *.
+ All uses changed. Check for overflow in internal size calculation.
+
+ * getusershell.c (readname): Simplify the code by using x2nrealloc
+ rather than xmalloc/xrealloc.
+ * linebuffer.c (initbuffer, readlinebuffer): Simplify the code by
+ using x2realloc rather than xmalloc/xrealloc. Also, fix a C
+ conformance bug: the old code used a pointer after freeing the
+ storage that it addressed.
+ * hash.c (hash_initialize): Simplify the code by using xalloc_oversized
+ rather than doing it by hand.
+ * getgroups.c (getgroups): Don't use xrealloc, since we don't need
+ the buffer preserved. Use free and xmalloc instead.
+ * quotearg.c (quotearg_n_options): Likewise.
+ Use a simpler test for size overflow. Don't use xalloc_oversized
+ because unsigned int might be wider than size_t (!); this suggests
+ that we should switch from unsigned int to size_t for slot numbers.
+
+2003-10-27 Bruno Haible <bruno@clisp.org>
+
+ * stdbool_.h: Better support for BeOS.
+
+2003-10-27 Paul Eggert <eggert@twinsun.com>
+
+ * exclude.c (new_exclude): Use xzalloc rather than xmalloc
+ to allocate the returned structure. Do not allocate a subarray,
+ as x2nrealloc will do that.
+ (add_exclude): Use x2nrealloc to reallocate ex->exclude,
+ instead of xnrealloc.
+ (add_exclude_file): Use x2realloc instead of malloc + xnrealloc.
+
+2003-10-26 Paul Eggert <eggert@twinsun.com>
+
+ * xalloc.h (xalloc_oversized): New static inline function, for
+ callers that want to do their own size-overflow checking. Include
+ <stdbool.h>, since xalloc_oversized returns bool.
+ * xalloc.c (array_size_overflow): Remove. All callers changed
+ to use xalloc_oversized.
+
+ Add two functions x2realloc, x2nrealloc, for programs that grow
+ arrays dynamically by doubling their sizes.
+ * xalloc.h (x2realloc, x2nrealloc): New decls.
+ * xmalloc.c (x2nrealloc_inline, x2nrealloc, x2realloc):
+ New functions.
+
+ Port to C99 semantics for 'inline' of external functions.
+ Bug reported by Bruno Haible.
+ * xmalloc.c (xnmalloc_inline): New static inline function,
+ with the old contents of xnmalloc.
+ (xnmalloc, xmalloc): Use it.
+ (xnrealloc_inline): New static inline function,
+ with the old contents of xnrealloc.
+ (xnrealloc, xrealloc): Use it.
+
+ * alloc.c (alloca): xmalloc cannot return NULL, so don't test for that.
+
+2003-10-25 Paul Eggert <eggert@twinsun.com>
+
+ Fix several address-calculation bugs in the hash modules,
+ plus some minor code cleanup.
+
+ * hash.h: Include <stdbool.h>, for bool.
+ * hash.c: Don't include <stdbool.h>, since hash.h does it now.
+ * hash.h (Hash_hasher, hash_get_n_buckets, hash_get_n_buckets_used,
+ hash_get_n_entries, hash_get_max_bucket_length,
+ hash_get_entries, hash_do_for_each, hash_string, hash_initialize,
+ hash_rehash): Use size_t rather than unsigned.
+ * hash.c (struct hash_table, hash_get_n_buckets,
+ hash_get_n_buckets_used, hash_get_n_entries,
+ hash_get_max_bucket_length, hash_table_ok, hash_print_statistics,
+ hash_get_entries, hash_do_for_each, hash_string, is_prime,
+ next_prime, hash_initialize, hash_rehash, hash_delete, hash_print):
+ Likewise.
+ (SIZE_MAX): Define if not defined.
+ (hash_get_max_bucket_length, hash_table_ok, hash_lookup,
+ hash_get_first, hash_get_next, hash_get_entries, hash_do_for_each,
+ hash_print):
+ Use const * when possible.
+ (hash_string): Use (unsigned char) *P rather than *(unsigned char *) P.
+ (check_tuning): Fix bug: if tuning parameters were very close to
+ 0 or 1, rounding errors could have caused subscript violations.
+ (hash_initialize, allocate_entry, hash_print): Remove unnecessary cast.
+ (hash_initialize): Add 'fail:' label
+ to free table and return NULL, and use it to simplify code.
+ Use calloc rather than clearing the storage ourself.
+ (hash_initialize, hash_rehash): Check for arithmetic overflow in
+ buffer size calculations.
+ * hash-pjw.h (hash_pjw): Use size_t, not unsigned.
+ Include <stddef.h>, for size_t.
+ * hash-pjw.c (hash_pjw): Likewise.
+ Switch to method described by Bruno Haible.
+ Include <limits.h>, for CHAR_BIT.
+ (SIZE_BITS): New macro.
+
+2003-10-21 Paul Eggert <eggert@twinsun.com>
+
+ * getndelim2.c (getndelim2): When size calculation overflows,
+ ceiling the allocation at NMAX bytes rather than silently
+ discarding input bytes before NMAX is reached. This makes
+ a difference only if NMAX exceeds SIZE_MAX / 2.
+
+ * obstack.c: Merge from glibc.
+ [defined _LIBC]: Include <obstack.h>, not "obstack.h".
+ Add libc_hidden_def (_obstack_newchunk).
+ (_obstack_free) [! defined _LIBC]: Remove.
+ [defined _LIBC]: Make a strong alias from obstack_free, rather than
+ a clone of the function body.
+ (fputs) [defined _LIBC && defined USE_IN_LIBIO]: Remove.
+ [defined _LIBC && !defined USE_IN_LIBIO]: Include <libio/iolibio.h>.
+
+ * obstack.h: Indenting cleanup, to make it easier to merge with glibc.
+ (obstack_grow, obstack_grow0): Remove unnecessary parentheses around
+ arg to memcpy.
+
+ * obstack.h (obstack_1grow_fast): Properly parenthesize arg.
+ (obstack_ptr_grow_fast, obstack_int_grow_fast):
+ Don't use lvalue casts, as GCC plans to remove support for them
+ in GCC 3.5. Reported by Joseph S. Myers. This bug
+ was also present in the non-GCC version, indicating that this
+ code had always been buggy and had never been widely used.
+ (obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank):
+ Use the fast variant of each macro, rather than copying the
+ definiens of the fast variant; that way, we'll be more likely to
+ catch future bugs in the fast variants.
+
+2003-10-20 Bruno Haible <bruno@clisp.org>
+
+ * wait-process.h: New file, from GNU gettext.
+ * wait-process.c: New file, from GNU gettext.
+
+2003-10-19 Jim Meyering <jim@meyering.net>
+
+ * vasnprintf.c (vasnprintf): Work around losing snprintf on HPUX 10.20.
+
+2003-10-16 Paul Eggert <eggert@twinsun.com>
+
+ * getgroups.c: Include <errno.h>, <stdlib.h>.
+ (getgroups): First arg is int, not size_t.
+ Don't let 'free' mangle errno.
+
+2003-10-16 Jim Meyering <jim@meyering.net>
+
+ * xmalloc.c: Include <string.h>, for declarations of memset and memcpy.
+
+2003-10-15 Paul Eggert <eggert@twinsun.com>
+
+ * exclude.c: Do not include <inttypes.h> or <stdint.h>.
+ (SIZE_MAX): Remove.
+ (new_exclude, add_exclude_file): Initial size no longer needs to
+ be a power of 2.
+ (add_exclude, add_exclude_file): Use xnrealloc instead of rolling
+ our own address arithmetic overflow checking.
+
+ * fnmatch.c (SIZE_MAX): Define if standard headers don't.
+ (fnmatch): Do not alloca more than 2000 wide characters;
+ instead, use malloc for large buffers.
+ Check for address arithmetic overflow, and return -1
+ with errno set to ENOMEM in that case.
+ * fnmatch_loop.c (ALLOCA_LIMIT): New macro.
+ (NEW_PATTERN): Do not alloca more than 8000 bytes;
+ instead, return -1. Check for address arithmetic overflow.
+
+2003-10-14 Paul Eggert <eggert@twinsun.com>
+
+ Handle invalid suffixes and overflow independently, so that
+ callers can treat them independently as needed. Fix some bugs in
+ suffix handling, e.g., "100k@" was not diagnosed as an invalid
+ suffix for a human-readable blocksize. The major caller-visible
+ change is the addition of a new
+ LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW enum value, indicating
+ that both overflow and suffix chars were found.
+
+ * human.c (humblock): Don't check separately for invalid suffix
+ char; that is xstrtoumax's job (now that its bug is fixed).
+ * xstrtoimax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [defined
+ INTMAX_MAX]: New macros.
+ * xstrtol.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM, TYPE_MINIMUM,
+ TYPE_MAXIMUM): New macros.
+ (bkm_scale, bkm_scale_by_power): Return strtol_error, not int.
+ (bkm_scale, bkm_scale_by_power, __xstrtol): Return maximal values
+ if overflow occurs, as it's what __strtol does and it's more useful
+ in practice.
+ (__xstrtol): If __strtol reports some error other than ERANGE,
+ reflect it to the caller as LONGINT_INVALID. If it reports
+ ERANGE, continue the rest of parsing, and report LONGINT_OVERFLOW
+ | LONGINT_INVALID_SUFFIX_CHAR if both errors occur.
+ * xstrtol.h (LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW): New enum
+ value.
+ (_STRTOL_ERROR): Handle it. Abort when given unknown error codes.
+ * xstrtoul.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM): New macros.
+ * xstrtoumax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM)
+ [defined UINTMAX_MAX]: New macros.
+
+2003-10-14 Bruno Haible <bruno@clisp.org>
+
+ * fatal-signal.h: Improved comments. Suggested by Paul Eggert.
+ * fatal-signal.c: Use sig_atomic_t. Suggested by Paul Eggert.
+ Also use volatile where needed.
+
+2003-10-12 Paul Eggert <eggert@twinsun.com>
+
+ * xalloc.h (xnmalloc, xzalloc, xnrealloc, xclone): New decls.
+ (XMALLOC, XCALLOC, XREALLOC, XFREE, CCLONE, CLONE): Deprecate,
+ and define in terms of the other primitives.
+ * xmalloc.c: Include stdbool.h; do not include exit.h.
+ (SIZE_MAX): Define if not already defined.
+ (array_size_overflow): New function.
+ (xalloc_die): Abort instead of exiting if 'error' returns.
+ (xnmalloc, xnrealloc, xzalloc, xclone): New functions.
+ (xmalloc, xrealloc): Use them.
+ (xcalloc): Check for address arithmetic overflow.
+ * xstrdup.c (xstrdup): Use xclone, since memcpy should be
+ a bit faster than strcpy.
+
+2003-10-08 Paul Eggert <eggert@twinsun.com>
+
+ Merge getpass from libc, plus a few fixes.
+
+ * getpass.c (HAVE_STDIO_EXT) [_LIBC]: Define to 1.
+ Include <stdbool.h>.
+ Include <stdio_ext.h> if HAVE_STDIO_H, otherwise define
+ __fsetlocking to empty.
+ [_LIBC]: Do not include "getline.h" or "unlocked-io.h", but
+ do include <bits/libc-lock.h>.
+ Do not include <fcntl.h>; not needed.
+ [_LIBC]: Include <wchar.h>.
+ (NOTCANCEL_MODE): New macro.
+ (flockfile, funlockfile) [_LIBC]: New macros.
+ (__libc_cleanup_push, __libc_cleanup_pop, __getline, __tcgetattr)
+ [!_LIBC]: New macros.
+ (call_fclose): New function.
+ (getpass): Use it. Save tty stream separately; this simplifies the
+ code and makes it more reliable if stdin happens to equal stdout.
+ Invoke __fsetlocking on tty.
+ Handle thread cancellation if needed.
+ Namespace cleanup (use __tcgetattr, __getline).
+ Use bool for Booleans.
+ [USE_IN_LIBIO]: Handle wide streams.
+ [!_LIBC]: Unconditionally do the fseek, since we don't know what
+ stream might go where.
+
+ * unlocked-io.h: Include <stdio.h>, so that the caller
+ doesn't have to include <stdio.h> before us.
+ (clearerr_unlocked, feof_unlocked, ferror_unlocked,
+ fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked,
+ fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked,
+ putc_unlocked, putchar_unlocked): Define to the unlocked counterpart
+ if not declared, so that we can use getpass.c code from libc without
+ rewriting it.
+ (flockfile, ftrylockfile, funlockfile): New macros.
+

+ (version_etc_copyright): Declare as readonly.
+ (version_etc): Make this function variadic with a NULL-terminated list

+ (version_etc_va): New declaration.
+ * version-etc.c: Include stdarg.h, stdlib.h.
+ (version_etc_copyright): Declare as readonly.
+ (version_etc_va): New function. Provide a different translatable string
+ for each possible number of authors < 10. Abbreviate when there are 10
+ authors or more.
+ (version_etc): Make this function variadic. Call version_etc_va.
+ Suggestion from Gary V. Vaughan.
+
+ * long-options.h (parse_long_options): Change prototype: the authors
+ string is moved to the end and becomes variadic.
+ * long-options.c: Include stdarg.h.
+ (parse_long_options): Make this function variadic, too.
+ Call version_etc_va, not version_etc.

+
+2003-09-29 Paul Eggert <eggert@twinsun.com>

+
+2003-09-27 Paul Eggert <eggert@twinsun.com>
+
+ * minmax.h (MIN, MAX) [__STDC__ && defined __GNUC__ && __GNUC__ >= 2]:
