The makefile for dmd doesn't have the dependencies on .h files set up properly. 
If a .h file is changed, the thing to do is make clean and then build.

(Even when I do set up the .h file dependencies right, bit rot creeps in and 
wastes my time trying to figure out what went wrong. I just make clean and rebuild.)
