1 error generated.
This is because time_t is a long on amd64. To avoid the warning, just
copy the equivalent test from a few lines before, which is used in the
Windows case, and which is type safe.

extattr_set_{fd,file,link} is logically a write(2)-like operation and
should return ssize_t, just like extattr_get_*. Also, the user-space
utility was using an int for the return value of extattr_get_* and
extattr_list_*, both of which return an ssize_t.

Limit write requests to at most INT_MAX.
This prevents a certain common programming error (passing -1 to write)
from leading to other problems deeper in the library.

Update libarchive to 3.1.2
Some of new features:
- support for lrzip and grzip compression
- support for writing tar v7 format
- b64encode and uuencode filters
- support for __MACOSX directory in Zip archives
- support for lzop compresion (external utility)
Some of new features:
- New readers: RAR, LHA/LZH, CAB reader, 7-Zip
- New writers: ISO9660, XAR
- Improvements to many formats, especially including ISO9660 and Zip
- Stackable write filters to write, e.g., tar.gz.uu in a single pass
- Exploit seekable input; new "seekable" Zip reader can exploit the Zip
Central Directory when it's available; the old "streamable" Zip reader
is still fully supported for cases where seeking is not possible.

Vendor has integrated most of our local changes in revisions 3976-3979 so
future updates are going to be easier.

r204111 (uqs):
Fix common misspelling of hierarchy
r211054 (kientzle);
Fix -R when used with -p. Previously, the
uname and gname weren't overwritten, so the
disk restore would use those to lookup the
original uid/gid again. Clearing the uname
and gname prevents this.

r204111 (uqs):
Fix common misspelling of hierarchy
r207786 (kientzle):
Various manpage updates, including many long-option synonyms that were
previously undocumented.
r208028 (uqs):
mdoc: move remaining sections into consistent order
This pertains mostly to FILES, HISTORY, EXIT STATUS and AUTHORS sections.
r209152 (kientzle):
If the compressed data is larger than the uncompressed,
report the compression ratio as 0% instead of displaying
nonsense triggered by numeric overflow. This is common
when dealing with uncompressed files when the I/O blocking
causes there to be small transient differences in the
accounting.
r210720 (joel):
Fix typos.
r223541 (kientzle):
If there is a read error reading Y/N confirmation from the keyboard,
exit immediately with an error.
If there is an error opening or reading a file to put into the archive,
set the return value for a deferred error exit.
r223573 (kientzle):
The --newer-than test should descend into old
directories to look for new files.

mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the
bottom of the manpages and order them consistently.
GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

mdoc: consistently spell our email addresses <foo@FreeBSD.org>
r209031 (uqs):
mdoc nitpicking: the title argument shall be uppercase
r214822 (kientzle):
Clarify the naming: Methods that free an object should
be called "free". Retain the old "finish" names to preserve
source compatibility for now.
r214905 (kientzle):
If the Zip reader doesn't see a PK signature block
because there's inter-entry garbage, just scan forward
to find the next one. This allows us to handle a lot
of Zip archives that have been modified in-place.

Don't write data into an empty "file."

Fix cpio on ARM.
