This shit doesn't scale:

  $ time ./c4 c4.c c4.c hello.c 
  hello, world
  exit(0) cycle = 9
  exit(0) cycle = 22614
  exit(0) cycle = 9273075

  real	0m0.067s
  user	0m0.067s
  sys	0m0.000s
  $ time ./c4 c4.c c4.c c4.c hello.c 
  hello, world
  exit(0) cycle = 9
  exit(0) cycle = 22614
  exit(0) cycle = 9273075
  exit(0) cycle = 933197195

  real	0m5.834s
  user	0m5.827s
  sys	0m0.000s
  $ time ./c4 c4.c c4.c c4.c c4.c hello.c
Just kidding. :) Amazingly cool! Does anybody have a smaller self-hosing compiler & bytecode vm?

For the record:

  $ time ./c4 c4.c c4.c c4.c c4.c hello.c 
  hello, world
  exit(0) cycle = 9
  exit(0) cycle = 22614
  exit(0) cycle = 9273075
  exit(0) cycle = 933197195
  exit(0) cycle = -1428163377

  real	9m23.409s
  user	9m22.673s
  sys	0m0.020s
