Well, lets say that I compile Apache with gcc -march=i386 on one box
and gcc -march=pentiumpro on another. I'm guessing (but haven't
checked) that alignment of the structures will change. Maybe different
cc's on the same platform will produce different alignments as well.
This is just as bad as field reordering.
