- Change the code a bit to hopefully save some cycles.
I.e. (simplified) change
a = b + 1;
while (--b & 0x7)
/* ... */
to
a = b;
for (; b & 0x7; b--)
/* ... */
and
while (--a >= 0)
/* ... */
to
for (; a > 0; a--)

- Equip two function arguments of swab() with the 'restrict'

specified by POSIX.1-2001.
<strings.h> as the associated header file.
The prototypes have been moved there from <string.h> because
POSIX.1-2001 said so.
- Conditionally include either <strings.h> or <string.h> based
on whether the [r]index() or str[r]chr() functions are
compiled, respectively.
- Style(9) tells us to
- put a space after the return keyword
- to check for a NUL character without using the ! operator.
- use NULL instead of (type *)NULL where the compiler knows
the type.
Apply these rules.
- Rather use ANSI-C function definitions than K&R ones.
- For index(3), correct second function argument's type; it was
declared to be a `const char' before and is now an `int'.
is <strings.h> and not <string.h> anymore.
- Tell the reader about this change in the HISTORY section.
- Switch to use an ANSI-C function definition.
- Include <strings.h> instead of <string.h> in the source file.
the prototypes for both functions are now in the <strings.h>
header, as required by IEEE Std 1003.1-2001.
- Add one sentence about that in the HISTORY section.
- Include <strings.h> in the source file to have the prototypes
in scope when the _ANSI_SOURCE macro is defined.

Othewise, it's possible for select() to return successfully but

on behalf of a thread, we should check the POLLERR, POLLHUP, and
POLLNVAL flags as well to wake up the thread in these cases.

to fail needlessly if a reverse DNS lookup of the IP address didn't
come up with a hostname. As a comment in the code clearly stated,
the "damn hostname" was looked up only for the purpose of netgroup
matching. But if that lookup failed, the function bailed out
immediately even though in many cases netgroup matching would not
be used.
This change marks the hostname as unknown but continues. Where
netgroup matching is performed, an unknown hostname is handled
conservatively. I.e., for "+@netgroup" (accept) entries an unknown
hostname never matches, and for "-@netgroup" (reject) entries an
unknown hostname always matches.
In the lines affected (only), I also fixed a few bogus casts. There
are others, and in fact this entire file would be a good candidate
for a cleanup sweep.

o <machine/ansi.h> will continue to live so it can define MD clock
macros, which are only MD because of gratuitous differences between
architectures.
o Change all headers to make use of this. This mainly involves
changing:
#ifdef _BSD_FOO_T_
typedef _BSD_FOO_T_ foo_t;
#undef _BSD_FOO_T_
#endif
to:
#ifndef _FOO_T_DECLARED

the number of characters the converted address consumed.
The bug occurred when converting an AF_INET address.
- Remove the SPRINTF macro and use sprintf instead.
- Do not do string formatting using sprintf(3) and a
temporary buffer which is copied when the supplied
buffer provides enough space. Instead, use snprintf(3)
and the real destination buffer, thus avoid the copy.
