This is based on a change from OpenBSD:
"Fix restore so that it can actually restore files larger than 4GB by
changing the type of "size" to off_t in getfiles() plus little dependent
type cleanup, from Daniel Lucq."
It is an important for machines with 32 bit longs.
While here unsign the flags, also from OpenBSD.

in format strings.
- Use (void) instead of (void *) when discarding strcat(3) return value.
- Format string fixes to match variable types.
- Change canon() len parameter and getcmd() size parameter type from
int to size_t.
- Style Makefile and increase WARNS to 2.

the restore program to restore all dumped extended attributes.
If the restore is running as root, it will always be able
to restore all extended attributes. If it is not running
as root, it makes a best effort to set them. Using the -v
command line flag or the `verbose' command in interactive
mode will display all the extended attributes being set on
files (and at the end on directories) that are being restored.
It will note any extended attributes that could not be set.
The extended attributes are placed on the dump image immediately
following each file's data. Older versions of restore can work
with the newer dump images. Old versions of restore will
correctly restore the file data and then (silently) skip
over the extended attribute data and proceed to the next file.
This resolves PR 93085 which will be closed once the code
has been MFC'ed.
Note that this code will not compile until these header
files have been updated: <protocols/dumprestore.h> and
<sys/extattr.h>.

use backup methods other than files and tapes. The -P argument is
a normal sh(1) pipeline with either $DUMP_VOLUME or $RESTORE_VOLUME
defined in the environment, respectively.
For example, I can back up my home to three DVD+R[W]s as so:
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ad0s2e 40028550 10093140 26733126 27% /home
green# dump -0 -L -C16 -B4589840 -P 'growisofs -Z /dev/cd0=/dev/fd/0' /home
for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.
