won't work for long paths, but we can't descend more than one pathname
component beyond the directory anyway if we lack search permission.
Here is a transcript demonstrating the change, where oldls is ls(1)
linked with the old fts(3):
das@VARK:~> mkdir t && touch t/{a,b,c} && chmod u-x t
das@VARK:~> oldls t
a b c
das@VARK:~> oldls -l t
das@VARK:~> \ls t
a b c
das@VARK:~> \ls -l t
ls: a: Permission denied
ls: b: Permission denied

Use cast rather than back-pointer to convert from public to private

"A trailing newline is added if none is present."
The code in syslogd, stderr, and console output always adds a newline
at the EOL. However, the existing code never actually removed a
trailing newline, and apparently relied on syslogd to convert it
into a space character. Thus, the existing newline was converted
to a trailing space at the EOL by syslogd, while stderr, and console
output resulted in an empty line.

of stat(2) calls by keeping an eye of the number of links a directory
has. It assumes that each subdirectory will have a hard link to its
parent, to represent the ".." node, and stops calling stat(2) when
all links are accounted for in a given directory.
This assumption is really only valid for UNIX-like filesystems: A
concrete example is NTFS. The NTFS "i-node" does contain a link
count, but most/all directories have a link count between 0 and 2
inclusive. The end result is that find on an NTFS volume won't
actually traverse the entire hierarchy of the directories passed
to it. (Those with a link count of two are not traversed at all)
The fix checks the "UFSness" of the filesystem before enabling the
optimisation.

adjunct maps are used. One symtom of this bug is sshd saying:
login_get_lastlog: Cannot find account for uid X
when logging in. The problem here is caused by an incorrect reuse of the rv
variable when previous values are needed later.
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).
There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.
Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

overridden by the threads library to provide a userland version
of non-pshared semaphores and cancellation points. Also add
a sem_timedwait().
The libc version of semaphores always uses kernel semaphores
regardless of whether pshared is set or not. When threads are
not present, it is difficult to get sem_wait() or sem_timedwait()
to do the right thing (since pthread_cond_timedwait() and
pthread_cond_wait() are stubs in libc and just return immediately).
For pshared semaphore, this commit still does not enable cancellation
point, I think there should be a pthread_enter_cancellation_point_np
for libc to implement a safe cancellation point.

present in the internal `nis_passwd' function. The lookup in the
adjunct map used the name passed into `nis_passwd', however no name
was of course supplied by getpwent or getpwuid. Correctly use the
name from the `struct pwd' that was found instead.
