exists and anyway it was so heavily changed from the old cccp
code as to be unrecognizable. Include full-write.h.
(full_write) Return size_t, with short writes meaning failure.
All callers changed. This fixes a bug with large buffers
on 64-bit hosts.
(free_exclude): New decl.
(add_exclude, add_exclude_file): Now takes int options arg.
(excluded_filename): No longer requires options arg, as the options
are determined by add_exclude. Now returns bool, not int.
This fixes one or two unlikely storage allocation overflow bugs,
but doesn't change user-visible behavior otherwise.
(bool): Declare, perhaps by including stdbool.h.
(<sys/types.h>): Include only if HAVE_SYS_TYPES_H.
(<stdlib.h>, <string.h>, <strings.h>, <inttypes.h>, <stdint.h>):
Include if available.
(<xalloc.h>): Include
(SIZE_MAX): Define if <stdint.h> or <inttypes.h> doesn't.
(verify): New macro. Use it to verify that EXCLUDE macros do not
collide with FNM macros.
(struct patopts): New struct.
(struct exclude): Use it, as exclude patterns now come with options.
(new_exclude): Support above changes.
(new_exclude, add_exclude_file):
Initial size must now be a power of two to simplify overflow checking.
(free_exclude, fnmatch_no_wildcards): New function.
(excluded_filename): No longer requires options arg, as the options
are determined by add_exclude. Now returns bool, not int.
(excluded_filename, add_exclude):
Add support for the fancy new exclusion options.
(add_exclude, add_exclude_file): Now takes int options arg.
Check for arithmetic overflow when computing sizes.
(add_exclude_file): xrealloc might modify errno, so don't
realloc until after errno might be used.
of copyright with `%s' so translators don't get an untranslated message in 2002.
(COPYRIGHT_YEAR): Define.
(version_etc): Use fprintf rather than fputs.
