While this is extremely primative by modern JIT standards, it is
extremely good by modern Open Source standards, so I'm quite thankfull
for it.

If no one else does, this is something I'll invenstigate in the
future.

I'll probably wind up writing one, and if I do, I will certainly
submit it - it seems like it should just be gluing a bunch of
functions together and proving an 'extern "C" ' decleration.

What sort of interface should such an interface provide? The simplest
is "pass-in-a-string-to-compile", but that's rather crude.
