This just means your compiler was compiled with -DDEBUG.  Ideally we should 
have a flag for disabling debugging output for use when running the test 
suite, otherwise -DDEBUG is less useful than it should be.  If we did this, 
then arguably validate should use -DDEBUG... but it will slow things down.
