We don't need or want them on UN*X (for one thing, we do fat builds on
OS X, and SIZEOF_LONG doesn't have the same value in ILP32 and LP64),
and don't need them on Windows, either (long is 32 bits in both Win32
and Win64).
each source file, only the headers that file needs, and all the headers
it needs in order to compile on various platforms and not to get any
avoidable compiler warnings on those platforms (as well as any
incomplete structure definitions needed to avoid those warnings).
That also means that <pcap.h> doesn't include <pcap-stdinc.h> on UNIX;
we don't want it to include <pcap-stdinc.h>, at least on UNIX, as doing
so
1) would mean we'd have to install that, so that programs can
build with libpcap
and
2) would mean that programs including <pcap.h> would drag in a
bunch of header files that they don't need.
Put a newline at the end of "inet.c" - the Sun C compiler doesn't like
it if the last line doesn't end with a newline.
