--- Comment #4 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
This is the warning we get when "fixed":

/home/manuel/test3/src/gcc/testsuite/gfortran.dg/wunused-parameter.f90:8:0:

 SUBROUTINE sub (neq, time, y, dydt)
^
Warning: unused parameter ‘time’ [-Wunused-parameter]

There is no such warning with 4.3.1
