That should be an issue only if the capture file has a size that doesn't
fit into an "int"; there *should* be function prototypes in scope when
routines that take that offset as an argument are called, so that the
compiler should widen that "int" to "off_t" as necessary.

Perhaps there's some place where there's no prototype in scope.

Do you have "zlib" configured in?  (The code path for reading files is
different in versions with "zlib" configured in and with "zlib" not
configured in, and there's a problem with "zlib" on FreeBSD that I
worked around by arranging that Wiretap not define HAVE_UNISTD_H -
perhaps NetBSD has a problem with "zlib" if you *don't* define
HAVE_UNISTD_H.)

Hmm.  The latest Ethereal, as checked out from CVS, works fine at work
with that capture file on a Solaris 2.5.1 system.  I'll try it on
FreeBSD this evening to see if it's a *BSD issue.
