 With a bit of tinkering Cody Boone Ferguson got this to work on modern systems.
 We thank him for his assistance!

-	In a nutshell, this is probably the slowest and most
-	obnoxious factorial program ever written.  Unfortunately, 
-	the name of the C source must be "ouroboros.c"; the name is

-	The source is a legal shell script and a legal C program.  
-	The shell script compiles itself, and then executes the
-	resulting binary, giving the source as input.  The program 
-	works by successively modifying #define lines each pass through.
