Subject: [Bug fortran/61126] [4.10 Regression] gfortran does not enable -Wununused-parameter with -Wextra

The gfortran manual reads:

-Wunused-parameter
Contrary to gcc's meaning of -Wunused-parameter, gfortran's implementation of
this option does not warn about unused dummy arguments (see
-Wunused-dummy-argument), but about unused PARAMETER values. -Wunused-parameter
is not included in -Wall but is implied by -Wall -Wextra. 

This should probably be changed if -Wunused-parameter is implied by -Wextra.

Note that if -Wextra can be used alone without implying -Wall, it is yet
another poor choice for the -W naming (starting with -Wall which is not all
warnings at all).
