Require jm_AC_TYPE_UINTMAX_T and jm_AC_TYPE_UNSIGNED_LONG_LONG since they
are needed to parse the include file.
Do not require jm_AC_HEADER_INTTYPES_H; it's obsolete.
Check for inttypes.h.
Simplify logic behind the args to AC_REPLACE.
(<stdlib.h>, <unistd.h>): Include if available.
("xalloc.h"): Include.
(xmalloc, xstrdup, free): Remove decls; no longer needed.
(xgetcwd): Don't assume sizes fit in 'unsigned'.
Check for overflow when path size gets too large.
Simplify failure code.
NO_IGNORE_CASE_OPTION, NO_WILDCARDS_OPTION, NO_WILDCARDS_MATCH_SLASH_OPTION,
WILDCARDS_OPTION, WILDCARDS_MATCH_SLASH_OPTION): New enum values.
(long_options, usage, decode_options): Add support for --anchored,
--ignore-case, --no-anchored, --no-ignore-case, --no-wildcards,
--no-wildcards-match-slash, --recursion, --wildcards,
--wildcards-match-slash.
(decode_options): Implement the new way of interpreting exclude patterns.
(usage): --newer-mtime takes a DATE operand. DATE may be a file name.
(OPTION_STRING, decode_options): Add -I, -y. Currently these options
just print error messages suggesting alternatives.
(add_filtered_exclude): Remove.
However, check for error even for '-' or '+' case.
(print_header): Try parsing uids and gids as unsigned integers first,
and as a uid_t or gid_t only if that fails. This adds support for
listing positive uids and gids that are greater than UID_MAX and
GID_MAX.
Support hard links to symbolic links.
(struct delayed_symlink): Remove 'names' member, replacing it with
'sources' and 'target' member. All uses changed.
(struct string_list): New type.
(delayed_set_stat, extract_archive): Use offsetof when computing sizes
for struct hack; this avoids wasted space in some cases.
(extract_archive): Fix test for absolute pathnames and/or "..".
Use link_error to report errors for links.
Remove redundant trailing '/' at "really_dir", for all uses, not
just before invoking mkdir.
If overwriting old files, do not worry so much about existing directories.
Fix mode computation in the case where the directory exists.
(apply_delayed_symlinks): If we can't make a hard link to a symbolic
link, make a copy of the symbolic link.
Accommodate new gfdl sectioning.
New option --recursion (the default) that is the inverse of --no-recursion.
New options --anchored, --ignore-case, --wildcards,
--wildcards-match-slash, and their negations (e.g., --no-anchored).
Along with --recursion and --no-recursion, these control how exclude
patterns are interpreted. The default interpretation of exclude
patterns is now --no-anchored --no-ignore-case --recursion
--wildcards --wildcards-match-slash.
