lynx-dev patch: REUSE_TEMPFILE fixed for DJGPP port

[Leonid Pauzner]

Cleaning up my hard disk I found out my old notes
on lynx.cfg option REUSE_TEMPFILES for DJGPP lynx port.
The problem still not fixed: temp file is not truncated to zero size
but grouth in length each time.

Well, I found an obvious fix (HAVE_TRUNCATE was not defined for DJGPP),
but how about platforms which happens have no truncate()
nor HAVE_TRANCATE defined?
>From LYUtils.c::LYOpenTempRewrite():

    } else if (is_ours) {
        /*
         *  Yes, it exists, is writable if we checked, and everything
         *  looks ok so far.  This should be the most regular case.
         *  We truncate and then append, this avoids having a small
         *  window in which the file doesn't exist. - kw
         */
#if HAVE_TRUNCATE
        if (truncate(fname, 0) != 0) {
            CTRACE(tfp, "... truncate(%s,0) failed: %s\n",
                   fname, LYStrerror(errno));
            return (LYOpenTemp(fname, suffix, mode));
        }
#endif
        return (LYReopenTemp(fname));
