Well, I can, but I also need some feedback on licensing issues, since if 
there isn't going to be an LGPL form of tcc in the next couple of weeks, 
then I really can't justify this development work.

That's basically what I do, the symbol relocation/resolution is a little 
more complicated.

I don't really have a need for a C REPL at this point, but I will 
probably in a month or two.
I'd look at a gdb-like interface, particularly with 'print' support.

More immediately I need type introspection support and more flexible 
memory management for relocated code.
Actually I also need to cache type and macro definitions for later 
compilation, so that might tie into a REPL or pre-compiled header support.
