Not only that, but it is quite common [at least for some architectures
I'm familiar with (*cough*) (*cough*)] for the native C compiler and/or
assembler to contain bunches of "workarounds" for CPU chip bugs. So a
Lisp compiler that emits machine code directly needs to implement all
the same workarounds... (*ugh!*)  for every architecture you want it
to run on... (*ugh!*)  To me, that's another real advantage of using C
as the target.
