So, for the first time ever I thought I would try my hand at generating c output using mzc and take a look at what is being generated, or could be generated with optimizations turned on. Below find the mzc command line and stdout for a simple file that contains a recursive and an iterative implementation of factorial along with a timed test run of both. BTW, I tried the code in and out of a module with precisely the same results. ---------------------BEGIN mzc output -------------------------- C:\Documents and Settings\kyle\My Documents\Scheme\math>mzc -c --unsafe-disable-interrupts --unsafe-skip-tests --unsafe-fixnum-arithmetic factorial.scm mzc v369.8 [3m], Copyright (c) 2004-2007 PLT Scheme Inc.

All rights reserved. factorial.c [output to ".\factorial.c"] -------------------END mzc output ------------------------------ The problem is that the ".\factorial.c" is not created, despite the message indicating that it was. Can someone with more experience with mzc shed some light on what I may be missing?
