I've just tried with

$ gfortran --version
GNU Fortran (GCC) 4.7.1 20120331 (prerelease)

$ gfortran -c -Wunused-parameter unused.f90
unused.f90:2.23:

integer, parameter :: i = 0
                       1
Warning: Unused parameter 'i' declared at (1)
unused.f90:1:0: warning: unused parameter ‘x’ [-Wunused-parameter]

and

$ gfortran --version
GNU Fortran (GCC) 4.8.0 20120330 (experimental) [trunk revision 185988]

$ gfortran -c -Wunused-parameter unused.f90
unused.f90:2.23:

integer, parameter :: i = 0
                       1
Warning: Unused parameter 'i' declared at (1)
unused.f90:1:0: warning: unused parameter ‘x’ [-Wunused-parameter]
