And if we get it right, all those 64-bit architectures will not find themselves in the same predicament m68k is in now, once vendors of shiny 128-bit and 256-bit architectures start tossing them on the scrap heap. How will they avoid that predicament? By following our lead, and making struct member alignment decisions explicit.
