Benefits:
1. If a header file gets modified, all dependent stuff gets rebuilt.
No need for 'make clean' after each header modification, no more
spurious errors, no more spurious rebuilds.
2. No more errors due to redefined preprocessor, compiler, and linker
FLAGS.
3. Build scripts don't try to build every *.cc file which happen to
lurk in the source directory.
