[burnus at gcc dot gnu dot org]

As suggested at
http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/a19c9fdd1503e9c5/

While gfortran does not has this kind of warning, g95 -Wextra warns:

In file crud.f90:5
integer, parameter :: one = 1
                      1
Warning (159): PARAMETER 'one' at (1) is never used
In file crud.f90:11
subroutine bar()
           1
Warning (167): PRIVATE module procedure 'bar' at (1) is never invoked

for the following file


module crud_mod
implicit none
private
public :: foo
integer, parameter :: one = 1
contains
subroutine foo()
print*,"foo"
end subroutine foo
!
subroutine bar()
print*,"bar"
end subroutine bar
end module crud_mod
