* man/local.mk: Add $(EXEEXT) suffix to the executables,
which is significant on OS/2 for example.

* src/system.h: Add a missing __OS2__ ifdef guard.
Also adjust spacing around () to avoid a syntax-check failure.

OS/2 traditional shells(cmd) do not expand a response file(@file)
or a wildcard. Expand them in each utility itself.
* src/system.h (initialize_main): Define on OS/2. Expand a response
file and a wildcard.

glibc <= 2.5 would crash when passed invalid long double values,
therefore internal gnulib routines were used, essentially only by od,
to output such invalid values. Later glibc versions don't crash,
as per https://sourceware.org/bugzilla/show_bug.cgi?id=4586
and subsequently od was adjusted to use the system printf routines
through the use of the ftoastr module with commit v8.7-22-ga71c22f.
Consequently our testing of this feature was moot, and use of
the gnulib printf replacement for printf(1), od(1) and error(3) etc.
was redundant.
* configure.ac (gl_printf_safe): Unset so that we don't check that
"nan" is output for these long double values.
* tests/misc/od-float.sh: Adjust all existing checks to fail if od
exits with failure status (like crashing for example). Add a new case
for one of the problematic invalid long double values for x86_64.
We only check that od exits successfully at present, which may change
if https://sourceware.org/bugzilla/show_bug.cgi?id=17661 is resolved.

* gl/lib/rand-isaac.c (isaac_refill): readisaac() purposefully passes
unaligned pointers to avoid memory copies. This is only done on
platforms where this is defined, so avoid the associated
runtime warning generated with -fsanitize=undefined, which is:
lib/rand-isaac.c:125:182: runtime error: store to misaligned address

Prompted by the implicit -O3 added by american-fuzzy-lop,
seen with GCC 4.9.2 on x86_64.
src/pr.c: In function 'print_files.part.5':
src/pr.c:1781:6: error: assuming signed overflow does not occur
when simplifying conditional to constant [-Werror=strict-overflow]
if (cols_ready_to_print () == 0)
This happens because cols_ready_to_print() is inlined
thus reducing the comparison to the N variable in print_page().
Now this can't overflow due to the protection when parsing the
specified column, but use an unsigned type to avoid the
apparent signed overflow.
* src/pr.c (cols_ready_to_print): Increment an unsigned type to
avoid the subsequent signed overflow warning.

This patch fixes the handling of sub-bind-mount cycles which are
incorrectly detected as the file system errors. If you bind mount the
directory 'a' to its subdirectory 'a/b/c' and then run 'du a/b' you
will get the circular dependency warning even though nothing is wrong
with the file system. This happens because the first directory that is
traversed twice in this case is not a bind mount but a child of bind
mount. The solution is to traverse all the directories in the cycle
that fts detected and check whether they are not a (bind) mount.
* src/du.c (mount_point_in_fts_cycle): New function that checks whether
any of the directories in the cycle that fts detected is a mount point.
* src/du.c (process_file): Update the function to use the new function
that looks up all the directories in the fts cycle instead of only the
last one.
* tests/du/bind-mount-dir-cycle-v2.sh: New test case that exhibits the
described behavior.
* tests/local.mk: Reference the new root test.
* NEWS: Mention the bug fix.

"zu" was output on solaris 8 for example rather than the number,
since coreutils-8.22.

our usage with error() currently works only through an ancillary

it in the options list according to alphabetic order.

commit v8.22-125-g9d736f8 printed placeholder "-" values
for device names that didn't match the preferred device name
for a particular mount point. However that was seen to erroneously
suppress values for aliased host names or exports, common with
remote file systems.
* src/df.c (me_for_dev): Rename from devname_for_dev() so that
we can determine the remoteness as well as the name for the
preferred mount entry.
(get_dev): Don't output place holder values when both
current and preferred mount entries are remote.

file_t is now mapped to unlabeled_t as per:
http://danwalsh.livejournal.com/68189.html
Therefore use the latter to ensure we match correctly.
This is needed on >= Fedora 21 for example,
while it also works on earlier releases.

We may run into a race condition if we treat hard links to the same file
as distinct files. If we do 'mv a b' and 'mv b a' in parallel, both a
and b can disappear from the file system. The reason is that in this
case the unlink on src is called and the system calls can end up being
run in the order where unlink(a) and unlink(b) are the last two system
calls. Therefore exit with an error code so that we avoid the potential
data loss.
* src/copy.c (same_file_ok): Don't set unlink_src that was used by mv,
and return false for two hardlinks to a file in move_mode.
*src/copy.c (copy_internal): No longer honor the unlink_src option,
used only by mv.
NEWS: Mention the change in behavior.
* tests/cp/same-file.sh: Augment to cover the `cp -a hlsl1 sl1` case.
* tests/mv/hard-verbose.sh: Remove no longer needed test.

Also remove the .1s sleep in each of the 50 iterations
to reduce the running time of the test and thus the
expensive_ tag on this test was removed.
Also ensure that we use the standard exit procedure
upon failure to avoid any erroneous diagnostics due
to persistent files on NFS.

Previously cp would not detect runs of NULs that were
smaller than the buffer size used for I/O (currently 128KiB).
* src/copy.c (copy_reg): Use an independent hole_size, set to
st_blksize, to increase the chances of detecting a representable hole,
in a run of NULs read from the input.
(create_hole): A new function refactored from sparse_copy() and
extent_copy() so we have a single place to handle holes.
(sparse_copy): Adjust to loop over the larger input buffer
in chunks of the passed hole size. Also adjust to only call
lseek once per hole, rather than at least once per input buffer.

Prompted by http://hydra.nixos.org/build/15682577
with GCC 4.8.3 on i686
src/tac.c:557:6: error: assuming signed overflow does not occur
when simplifying conditional to constant [-Werror=strict-overflow]
if (bytes_copied < 0)
This happens because copy_to_temp() is inlined in tac_nonseekable(),
thus reducing the comparison to the bytes_copied variable in
copy_to_temp. Now this can't overflow on either 32 or 64 bit
due to the protection of the preceding fwrite(). We could use a
guard like "if (bytes_copied <= OFF_T_MAX - bytes_read)" to avoid
the warning, but rather than a runtime branch, just use an unsigned
type to avoid apparent signed overflow on systems where the accumulation
is not promoted to unsigned (32 bit size_t, 64 bit off_t).

avoid the subsequent signed overflow warning.

On some filesystems (BTRFS), moving a file within the filesystem may
cross subvolume boundaries and we can use a lightweight reflink copy,
similar to what cp(1) can do, which is faster than a full file copy.

"E.g." stands for latin "exempli gratia" which is typically read
