Looks like 90 minute scheme to C compiler does not work with new gambit - all's well until code-gen. At code gen, it appears that extra round brackets are emitted when we use new gambit. I am managing with 4.0 for now - I've gone through the CPS conversion and closure conversion (the video helped a lot). I am now going through code generation.

Sharing it just in case its a trivial something I need to do to get it working with new gambit...
