Instead, just skip it like the diagnostic says.
Reported by Paul Eggert.

reporting replaced files. This avoids a bug in the code,
which mishandled ino_t wider than long.

* src/remove.c (remove_dir): Likewise, twice.

(rm): Add a parameter to the prototype.
|

now required for rm.
|

call lstat `.' to get the device/inode numbers now required for rm.

removing unintended files. In one scenario, if root is removing a
hierarchy that is writable by the malicious user, that user may trick
root into removing all of `/'. Reported by Wojciech Purczynski.
(remove_dir): After chdir `..', call lstat to get the
dev/inode of "." and fail if they aren't the same as the old numbers.
(remove_cwd_entries): New parameter, `cwd_dev_ino'.
(remove_dir): Likewise.
(rm): Likewise.
Adjust all callers.

(long_opts): Add --copy-contents.
(usage): Describe new behavior. Sort options.
(main): Implement new behavior. Remove diagnostics for -a and -r;
no longer needed.

issue a warning that `cp -r' is not portable.
|
|
cp -r once again preserves symlinks.
(usage): Document the original (now-restored) behavior.
|
|
|
|
whereby an unprivileged user could gain read access to otherwise-
inaccessible files when root uses cp or mv to copy a hierarchy
belonging to that user.

(strftime, time, stime): Remove declarations; no longer needed.
(usage): Document %N.
(main): Use gettime rather than time to get the time of day,
so that we can get fractional times.
Similarly for settime and stime, so that we can set fractional times
(though this currently is not available to the user since we don't
parse fractional times; add FIXMES for that).
Check for gettime failures; e.g. this can occur if it
is past 2038 and we are a 32-bit app running on a 64-bit OS.
Get fractional part of file time stamps.
Do not falsely report failures just because time_t happens to be -1
(e.g. a file time stamp 1 second before the epoch).
(show_date): 2nd arg is now struct timespec, not time_t.
All uses changed. Use nstrftime rather than strftime, so that
we can format fractional seconds.

(USE_ACL): Remove; replaced by HAVE_ACL everywhere.
(gobble_file): Use file_has_acl rather than doing it ourselves.

unsigned char *, to avoid some technical violations of the C
standard, and to avoid the need for casts. I guess the
unsigned char * was probably there for improved performance
with ancient compilers, but the code wasn't using the
unsignedness any more.
Reported by Nelson H. F. Beebe.
(cat): int -> size_t for full_write arg. This doesn't
fix any bugs since the buffer size is small, but it makes
the code a bit clearer.

-I option.

to seek back to the position we would have gotten to had we
been reading one byte at a time. POSIX currently doesn't
require this, but it's easy to do and some software relies on it.

consistent with all of the other `... is obsolete...' diagnostics.

support of obsolete "-N" option syntax in expand, head, fold,
split, tail, unexpand, uniq, and which prohibits options with
optional arguments in od and pr.
(usage): Document this.
(shortopts): New constant.
(main): Check for obsolete options.
