- update some comments

- split up DERIVED_SRCS into separate variables so we can refer to
  them separately in the specification of the various CLEAN_FILES
  variables.

- only clean happy-generated files in maintainer-clean mode

# We attempt to automatically devine the list of sources $(SRCS) to
