------- Comment #8 from dannysmith at users dot sourceforge dot net  2009-03-09 07:52 -------
>From gcc.info:

    *Warning:* the `-fpack-struct' switch causes GCC to generate code
     that is not binary compatible with code generated without that
     switch.  Additionally, it makes the code suboptimal.  Use it to
     conform to a non-default application binary interface.
