------- 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.
