This code is wrong.  It might work on some architectures, but it  
author needs to read K&R.  On many UNIXen including MacOS malloc.h is  
not in the default header search path.  Including stdlib.h includes  
types.h and malloc.h wherever they are.  This is the right thing to  
do and the code is wrong.

Make sure you did a make clean or otherwise removed all the old build  
products.

Of course none of this is anything to do with Swarm.  It is just C  
programming 101.
