No, according to the manual it isn't. I think one reason for confusion is the
naming of things in the different languages.
Named constants are called in Fortran "PARAMETER" and the thing you pass to a
procedure (function, subroutine) are called "(actual) arguments" - those get
associated with "dummy arguments"/"formal arguments".
In C, you call arguments "parameters". Thus, taking about "parameter" is highly
confusing. I think it neither really fits to named constants nor to arguments,
but since languages have chosen the term ...
From the gfortran man page:
"-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."
