It's exactly 32 bits. There's a uint_least32_t defined in C99 (and in
our headers and such) for the latter. However, I'm not convinced
there's ever been a serious implementation done that required that
mechanism, and most code both in and out of our tree certainly doesn't
use it.

I'm sure at this point someone could put together a 36-bit machine out
of FPGAs that ran fast enough to be used as a low-volume web server,
and there are certainly heterogeneity advantages to such a platform.
Maybe someone who knows enough about such things should actually do
this :-)
