My one complaint with the not defining something if it is not available, is if you have an IDE that can take you to the definition of a #define, then it takes you nowhere when it isn't defined.
If it is defined to zero, the it will be defined, and your IDE can take you to the place in the Config.h that has it set to zero, possibly with an explanation of why it is set to zero for this current build. I know IDEs have find in all files too, but that kicks up all the matches, not the one that you actually care about.
I know this is a little different than the way things are done now, but I do like this approach a bit better.
Does that make sense to everyone? Comments? Likes? Dislikes?
I am open to going either way. I just want to bring it up for discussion.
