Do the conservative thing and make sure enough space is available.

When it is called directly, gcc is smart enough to generate inline
code for it, which is why it wasn't noticed before that it was missing.
fabs() would probably better fit into libm, but it has traditionally been
in libc on FreeBSD, so there is probably software around that makes
assumptions about this by now.
of pointers to strings. These two arrays were fixed to the same size, but one
had an implicit zeroed trailer element, which was unused because the size was
used up by the ones before said zeroed trailer element. So the unused limb was
chopped off the over-sized-but-not-over-sized array, and everyone lived happily
ever after.

linked binaries from before the signal code move.

point for the binary search that works on both 32 and 64 bit types. I have
been using this for a while now.

is to be compiled.

Apply these rules.

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.
