Hi, Zach.  This is exactly what we do here.  My solution is as
follows:

1. You need my AfterBuild patch, which allows you to execute code
   after a specified target is built.

2. In your first step, also generate a list of the .c files into a
   text file.  Mention that file as one of the targets of your step 1
   command.

3. Write an AfterBuild action (in my AfterBuild patch) for the above
   text file, which should just add each filename seen into the link.
   (You may need to futz with this; I build a DLL, and cons knows how
   to do that in sections; Command and Program don't.)

4. Use your regular Command/Program target to define the main
   executable.

Sorry I can't provide more detail now; I have to run.  Email me
privately and I'll give you the AfterBuild patch and more details.
