[Bug fortran/33180] New: Cannot IMPORT symbols later defined in the module

[burnus at gcc dot gnu dot org]

The following program might be invalid as all compilers I tried (gfortran, g95,
ifort, NAG f95, ifort) reject it with:

IMPORT-name must be the name of an entity in the host scoping unit
Error: 't' name in IMPORT statement does not exist in a host program unit
Error: Cannot IMPORT 't' from host scoping unit at (1) - does not exist.
Cannot IMPORT T from host M - it does not exist

But I could not find anything in the standard which prohibits it (PLEASE
CHECK).
This is especially useful if one wants to use
  PROCEDURE(name_of_module_procedure) :: dummy_var_in_interface

Example:

module m
  implicit none
  interface
    subroutine ddd(b)
      import :: t
      type(t) :: b
    end subroutine
  end interface
  type t
    integer :: x
  end type t
end module m
