slightly-modified copies of those that used to be in cp-hash.c.
(struct entry) [coll_link]: Remove member.
(struct htab): Remove.
(hash_reset, hash_init, hash_insert2, hash_insert): Remove functions.
Include hash.h and same.h.
(htab): Change type of global to `struct hash';
(entry_hash, entry_compare, hash_ins): New functions.
(count_entry): Use hash_ins instead of hash_insert.
(copy_internal): Call remember_copied only for if the source file
has 1 < st_nlink, or if it's a directory.
Now that EARLIER_FILE is set conditionally, initialize it to NULL.
* src/uniq.c (enum delimit_method): s/DM_PRECEDE/DM_PREPEND/
and change all uses.
(delimit_method_string): s/precede/prepend/
Patch by Padraig Brady.
* src/uniq.c (usage): Correct typo in description of --all-repeated.
Patch by Padraig Brady.
Include <sys/ucred.h>, for Apple Darwin.
Include sys/mount.h and sys/fs_types.h only if available.
(FS_TYPE): Define.
(read_filesystem_list): Use FS_TYPE.
Check for these headers: sys/param.h sys/ucred.h sys/mount.h
sys/fs_types.h, and make the link-test for getfsstat guard #include
directives with appropriate #if HAVE_*_H tests so that we can
detect getfsstat on Apple Darwin1.3.7 systems.
Also fix harmless typo in cache variable name: s/getsstat/getfsstat/.
(struct Dest_info): Define.
(dest_info): Declare global.
(DEST_INFO_INITIAL_CAPACITY): Define.
(hash_pjw): New function.
(dest_info_hash): Likewise.
(dest_info_compare): Likewise.
(dest_info_init): Likewise.
(seen_dest): Likewise.
(record_dest): Likewise.
(copy_internal): If the destination exists, fail if it's in the set
of files that have already been created as part of this mv or cp.
(copy_internal) [move_mode]: Record the destination dev/ino/filename.
(copy_internal) [!move_mode, regular file]: Likewise.
