Bigloo targets C and JVM:

stalin compiles to c, and does ``whole program ``optimization''''

scm includes hobbit, but I haven't used it

bigloo was the only scheme implementation that targets c that didn't disappoint me in terms of performance. I remember chicken compiled code performing the same as interpreted guile. But my benchmarks are neither comprehensive nor scientific. The best advice is to try them all and then stick with one.
