I see. The big difference is that 2.95.x supports the option -Os,
while 2.7.x doesn't, so the image didn't shrink very much in my
environment (i.e. it was small enough without -malign-*).
However, I'm not sure if it is really a good thing to disable to
align loops, functions and jumps. Alignment is mostly not essential in
x86 and performance is not very impotant in GRUB, but GRUB shouldn't
be _too slow_. So the question is how much your change could degrade
the performance. I may not answer this, as I have no cpu in ancient
times, such as 486SX.
