I came into this late, so you might already know this, but try this on for 
size anyway:

# ifdef		DEBUG
#   define	debug(x)	fprintf x
# else
#   define	debug(x)
# endif

.....

	debug((stderr, "Control string", arg1, arg2, ... argn));

Cute, isn't it?  I stole it out of the src to enscript (adobe something or
