indicating that the user must set errno to 0 if they wish to
distinguish "no such user" from "error".

low bound, and the number of bytes remaining instead of storing the
raw byte sequence and deriving them every time mbrtowc() is called.
This is much faster -- about twice as fast in some crude benchmarks.
constants the wrong way on the VAX. Instead, use C99 hexadecimal
floating-point constants, which are guaranteed to be exact on binary
IEEE machines. (The correct hexadecimal values were already provided
in the source, but not used.) Also, convert the constants to
lowercase to work around a gcc bug that wasn't fixed until gcc 3.4.0.

Main ones: mostly use conditional expressions in ifdefs instead of a
mixture of conditional expressions and nested ifdefs.
Nearby ones:
- don't do less than echo the code in the comment about libc_r
- fixed some internal insertion sort errors and indentation errors.
Remove "sys/types.h" as "sys/param.h" is already included
Use cast rather than back-pointer to convert from public to private
version of FTS data, and so avoid littering fts.h with any of the
details.

"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.

RuneRange arrays. This is much faster when there are hundreds of
ranges (as is the case in UTF-8 locales) and was inspired by a
similar change made by Apple in Darwin.
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.
