All the MCU world does it... also DSPs tends to have.. curious datatypes,
like 16-bit chars. That's mean that sizeof char = 1 (by definition),
which means that the sizeof a 16-bit int is 1 too :D I've seen many
programmers stumbling upon this; just because most machines have 8-bit
words (externally at least) doesn't mean that Texas couldn't do
a 16-bit-word DSP. These same people go crazy on (s)harvard
architectures because pointers in data space are completely different
than pointer in code space (and DSP have 2 or more data spaces, too!).
But I digress :P

What *could* be useful is an ADA-like typedef where typedef something
int is *not* an int. This would need a cast to pass to everything which
uses int, which is the reason enums weren't used a lot in pascal:D
