--- Comment #6 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
With r258935 I get

% gfc pr52789.f90 -Wunused-parameter
pr52789.f90:2:23:

 integer, parameter :: i = 0
                       1
Warning: Unused parameter 'i' declared at (1) [-Wunused-parameter]

% gfc pr52789.f90 -Wunused-parameter -Wunused-dummy-argument
pr52789.f90:2:23:

 integer, parameter :: i = 0
                       1
Warning: Unused parameter 'i' declared at (1) [-Wunused-parameter]
pr52789.f90:1:14:

 subroutine s(x)
              1
Warning: Unused dummy argument 'x' at (1) [-Wunused-dummy-argument]

i.e. no "unused.f90:1:0: warning: unused parameter ‘x’ [-Wunused-parameter]",
gone with 6.4.0 and above.
