There's always TCC [1], a library which can compile code into memory that
can be called directly. I have a Lua wrapper for it [2] and code on top of
that that allows the loading of C based modules directly from source code
[3], as well as making an easy to use API for compiling C code.
On the good side, TCC compliles *fast* [4]. On the down side, the code it
produces is *not fast*. It's a trade off. And it's fun to play with.

source code, in under 10 seconds.
