[Bug fortran/42809] Too much noise with -Wconversion

There is also a lot of noise when a derived type with default
initialization is instantiated.  Moreover, the warnings point
to an unexpected locus.  Consider:

module bla
  implicit none
  integer, parameter :: i1 = 1, i2 = 2
  type t_datum
     integer(i1) :: state  = 0
     integer(i2) :: flags  = 0
  end type t_datum
  type t_x
    type(t_datum) :: a
    type(t_datum) :: b
  end type t_x
contains
  subroutine dummy
  end subroutine dummy
end module bla
!------------------------------------------------
module foo
  use bla, only: t_x,   &! Derived type
                 dummy   ! Some unused subroutine
  implicit none
contains
  subroutine work
    type (t_x)  :: x
  end subroutine work
end module foo


This gives:
