A question about this occurred to me last night.

BitC has only one machine-dependent type: word. The current runtime.h
file typedef's this in a machine-dependent way, but all of the C code
emitted by our current back end uses the typedef. Originally we intended
to have a self-hosting compiler, and this provided us with a way to do

LLVM has a back end that emits C code. How machine dependent is the
emitted C code?
