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

(There must surely be a piece of code excluding module variables from unused warnings? That needs to be taught about the private attribute.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31124 ^ permalink raw reply [flat|nested] 6+ messages in thread
