actually, i think it's worse than that. enough #ifdefs will make a given
set of programs work, after much hand tweaking, but for each new
program, you need to add even more #ifdefs.

| yes, they went for the model where long changes size like pointers.
| the difference is that relatively few applications see pointer representations
| but quite a few rely on shifts, masks, etc. of `long' that are functions of 32 not 64.
