That would make unsigned types, um, `interesting'.  I suspect it would
be a lot simpler to build a compiler for a mostly-C-like language that
happens to be better suited to the machine, kinda the way I've seen
almost-C compilers that had 8-bit ints, for microcontrollers....

This is getting rather far off of NetBSD topics, though.
