If you're going this way, please put this in common selftest code.
Don't force every single test to duplicate it.

But, seriously, this is all insanity.  Fixing the whole "oh, but DEBUG
might not be defined" thing is not exactly rocket science.  Just do this
in your test header or .c file:

#ifndef DEBUG
#define DEBUG 0
#endif

Then you can do:

	if (DEBUG)
		foo();

all day long.

Or, not.  I honestly don't think this is worth even mucking with in the
first place.
