Alignment of structures.

Thanks for your bug report. The behaviour you see is caused by the
macro DATA_ALIGNMENT in gcc/config/i386.c, which was introduced by

Fri May 15 01:29:39 1998  John Wehle  (john@feith.com)

	* i386.h (DATA_ALIGNMENT): Define.

I'm not sure what the rationale for this alignment is; I believe there
is some Intel recommendation in this respect.

Anyway, I fail to see the bug. Is it that something that should work
doesn't? Why is this a problem?

Regards,
Martin
