If we're going to visit the circles of hell, let's do it properly:
Step -1: Get it under source control and backed up.
Step -2: Find out if the source code corresponds to the executable. Which of the 7 variants of the source code (if any).
Step -3: Do dark rituals over a weekend with cdparanioa to scrape the source code from the bunch of scratched cd's found in someone's bottom drawer. Bonus point if said person died last week, and other eldritch horrors lurk in that bottom drawer. Build a VM clone of the one machine still capable of compiling it.
