• Compile the code with the ``good'' options
• Make a directory - ./good
• Move the object files to the ./good directory

• Compile the code with the ``bad'' options
• Make a directory - ./bad
• Move the object files to the ./bad directory

• Create a file listing all affected object files
• If necessary create a script to compare ``good'' & ``bad'' output
• Collect all the necessary input files together
