These are great tips, thanks... is it possible to avoid linking the
interpreter as well? That is, I'm pretty sure I always want to JIT code and
never interpret it, but it looks like I currently have to pay a codesize
penalty for the interpreter anyway.

Right now this is personal experimentation, but if Mozilla decides to use te
LLVM JIT for some of our Mozilla2 projects we'll definitely be contributing
to reduce the footprint as much as possible, as well as the MSVC thiscall
support I mentioned before.
