I've used libtcc from tcc to do something similar on a prototype listening on a socket to do queries over a 2 gig memory mapped file. I'd pass over the query as a string of C that would be dynamically compiled and executed by libtcc. It worked really well but ultimately didn't go anywhere other than research. Here's an example from the distribution (first google result for the file): http://www.koders.com/c/fidC76C8B834DFF05F1D0BD61220AC19E246.... TCC can be found here: http://bellard.org/tcc/

I am surprised more projects don't use TCC for that. It's an awesome little compiler and using it that way saves way more time over writing DSLs. Even projects that have to compile C all the time (like Lisp->C compilers such as ECL and Gambit Scheme) use GCC, which is stupid slow.
