src/contrib/isc-dhcp/includes/minires/resolv.h has a 'extern' definition
but it makes an error when linking crunched binary just like this:
dhclient.lo: In function `MRres_nquery':
dhclient.lo(.text+0x2dcce): undefined reference to `__h_errno_set'
dhclient.lo(.text+0x2dd5b): undefined reference to `__h_errno_set'
dhclient.lo: In function `MRres_nquerydomain':
dhclient.lo(.text+0x2de53): undefined reference to `__h_errno_set'
The author understands this will be a problem (see comments in resolv.h).
Murray said that the author will fix this, but as a temporary solution,
modifying the source code and not to use __h_errno_set.
BTW, I'm sorry that previous commitlog in src/sbin/dhclient/Makefile should
read "Found by:" instead of "Confirmed by"; I just found that rev 1.15
has a typo so fixed.

spares (the size of the field was changed from u_short to u_int to
reflect what it really ends up being). Accordingly, change users of
xucred to set and check this field as appropriate. In the kernel,
this is being done inside the new cru2x() routine which takes a
`struct ucred' and fills out a `struct xucred' according to the
former. This also has the pleasant sideaffect of removing some
duplicate code.

volumes are available, instead of getting stuck in a loop calling
getvol(). Normally restore in 'x' or 'i' modes will ask for a new
(earlier) volume when the current inode number on the tape is greater
than the last inode to be restored, since there can be no further
inodes of interest on that volume. However we don't want to change
volumes in this case either if the user explicitly said that there
are no more tapes, or if we are looking at the first volume.
When no more volumes are available but there are still inodes that
we have not found, we now just fall through to the code that prints
out a list of any missing files, so the restore completes normally.
Also simplify the logic a bit by always returning to the start of
the main for(;;) loop whenever the volume has changed.
This should completely fix the "Changing volumes on pipe input" bug
that is often observed when restoring dumps of active filesystems.

to multi-volume restores:
- In findinode(), keep a copy of header->c_type so that we don't
exit the do-while loop until we have processed the current header.
Exiting too early leaves curfile.ino set to 0, which confuses
the logic in createfiles(), so multi-volume restores with the
'x' command don't work if you follow the instructions and supply
the tapes in reverse order. This appears to have been broken
by CSRG revision 5.33 tape.c (Oct 1992).
- The logic in getvol() for deciding how many records to skip after
the volume header was confused; sometimes it would skip too few
records and sometimes too many, leading to "resync restore"
warnings and missing files. Skip to the next header only when
the current action is not `USING'. Work around a dump bug that
sets c_count incorrectly in the volume header of the first tape.
Some of the problems here date back to at least 1991.
- Back out revision 1.23. This appeared to avoid warnings about
missing files in the 'rN' verification case, but it made the
problems with the 'x' command worse by stopping getvol() from
even attempting to find the first inode number on the newly
inserted tape. The bug it addressed is fixed by correcting the
skipping logic as described above.
- Save the value of `tpblksread' in case the wrong volume is
supplied, because it is incremented each time we read a volume
header. We already saved `blksread' for the same reson.
Normally trewind() performs a close-open-close cycle to rewind the
tape when closing the device, but this is not ideal for fifos. We
now skip the final open-close if the output descriptor is a fifo.

This works by retokenizing a line with a split limit so that if the
argument count for a command is greater than the number of arguments
formed by splitting apart the line of user input, the last argument
is instead all of the remainder of the input line.
