It's funny you should mention the old days.
Thou shalt foreswear, renounce, and abjure the vile heresy which
claimeth that "All the world's a VAX", and have no commerce with
the benighted heathens who cling to this barbarous belief, that
the days of thy program may be long even though the days of thy
current machine be short.
[...] Beware, in particular, of the subtle and terrible "All
the world's a 32-bit machine", which is almost true today but
shall cease to be so before thy resume grows too much longer.
(Well, slightly old days. Almost 10 years old, and sage advice for
Palm OS programmers today.)

Standard C allows a lot of interesting choices to be made. Many of them
are becoming less likely choices, however, due to the apparent need to
pander to programmers who don't know what they're doing. For example,
it's unlikely that any new architectures will favour representing null
pointers as anything other than all-bits-zero, not because it's a bad
choice (on the contrary), but because people write non-portable code
because they Just Don't Get It.
