absolutely, even on machines which do not *require* alignbment from
a functional point of view (e.g. ia32[x86] or IBM mainframes), it makes
a big difference in performance to make sure that stuff is optimally
aligned. Indeed there is a continuing discussion thread about the fact
that things should be *more* aligned than they are. This is aggravated
by the fact that the microsoft ABI does not guarantee sufficient alignment
of the stack pointer on entry to a function.
