Put that wrapper, and the routine to get the interface list, in a

Fix up the Wiretap hack for dealing with said incompatibility to use the

with one capture I've seen, but perhaps that was done with an old
version of AIX, and newer versions use a minor version number, in the

However, libpcap hasn't used a minor version of 2 for ages, so perhaps
AIX hasn't updated their libpcap in ages, and aren't about to do so
soon. If they do, let's hope they change the magic number. The capture
file in question *does* have the capture length and real length in the
old, pre-2.3, order, so it really looks as if it's an old version,
rather than IBM trying to be "helpful" by using a different minor
version number so that you can distinguish between normal libpcap and
AIX libpcap formats.)

expanded at some point and that Sun *used* some of the new types (e.g.,
in atmsnoop), or decided on their own to go beyond those types to encode
an Oh-So-Useful link speed indication, or just didn't *care* that they
were just DLPI data link types.
Therefore, we have to map Shomiti link types to wiretap types using a
different mapping table. For now, we assume files with a version number
of 2 are snoop files, and version numbers of 3, 4, and 5 are Shomiti
files; Shomiti claims to use a version number of 2 as well, but to
determine whether a file with a version number of 2 is a snoop file or a
Shomiti file requires that we look at the header of the first packet and
assume that if there's more than 3 bytes of padding it's a Shomiti file.
The return value from "fwrite()" is a "size_t"; make the variable into
which we store it a "size_t", and then fix up the bugs that were
revealed by the compiler warnings that produced - "fwrite()" returns 0,

checking for "gzgets()" in zlib.
If there is a "zlib.h" header, and there is a "gzgets()" in zlib, check
whether we find "gzgets()" in zlib when we link with the GTK+ link
flags, and, if not, fail. People often grab XFree86 source and build
and install it on their systems, and they appear sometimes to
misconfigure XFree86 so that, even on systems with zlib, it assumes
there is no zlib, so the XFree86 build process builds and installs its
own "mini-zlib" in the X11 library directory. The "mini-zlib" lacks
"gzgets()", and that's the zlib with which Ethereal gets linked, so the
build of Ethereal fails.

That lets us get rid of "wtap_file()" in Wiretap.
It also lets us get rid of the include of "zlib.h" in "file.h"; the
#defines of "file_open()", "filed_open()", and "file_close()" are also
unnecessary, so we get rid of those as well.
However, that means we need to include <zlib.h> in "gtk/main.c" and

The offset, for a given packet, at which "ascend_seek()" should start
searching for that packet's header must be computed separately from the
offset, for that packet, at which "ascend_seek()" should start searching
for the *next* packet - if the file is a "wdd" capture, and the packet
has a "Date:" header and a WD_DIALOUT_DISP header, the search for that
packet should start at the beginning of the "Date:" header, but the
search for the next packet should start after the WD_DIALOUT_DISP
header, as if we start it after the "Date:" header, the search will stop
at the packet's own WD_DIALOUT_DISP header, as a packet could have a
WD_DIALOUT_DISP header but no "Date:" header.
