First, I forgot to mention that the behavior described in comment 0 is a 4.8
regression.

Second, there is another case which still gives bogus warnings (also a
regression), and that is ENTRY:


subroutine sub
entry en
end subroutine


Compiling this with -Wunused-function yields:

warning: ‘master.0.sub’ defined but not used [-Wunused-function]
 subroutine sub
