[Bug fortran/31154] New: IMPORT fails for "<imported symbol> FUNCTION (...)" kind of procedures

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

+++ This bug was initially created as a clone of Bug #30922 +++

gfortran currently does not like the following:
------------------------------------
module x
  implicit none
  integer, parameter :: d=8
  interface
    real(d) function y()
      import
    end function
  end interface
end module x
------------------------------------

    real(d) function y()
        1
Error: Parameter 'd' at (1) has not been declared or is a variable, which does
not reduce to a constant expression

(A real-world example for the latter is:
http://users.erols.com/dnagle/pub/pthread.f03,
which also needs ISO_C_BINDING support.)
