That would be nice, and we would have liked that too, but right now Vortex
computes offsets in structures to access fields and the like, and it's difficult
to avoid depending on the word size when doing this. We've thought about
generating code that would compute the offset from the word size etc. at C
compilation time, but we haven't pursued it, and things like alias analysis
might get very hard.
