(Split off from PR 31154.)
The following is accepted but invalid (without using "IMPORT t"):
module x
implicit none
type t
integer :: i
end type t
interface
type(t) function bar()
end function
end interface
end

------- Comment #1 from burnus at gcc dot gnu dot org 2007-09-08 08:09 -------
This probably needs the same technique as PR31229 / PR31154.
The following program is valid, but rejected by gfortran (also if one does not
rename the symbol):
func%i = 5
1
Error: Derived type 'z' at (1) is being used before it is defined
a.f90:7.21:
type(z) function func()
1
Error: The derived type 'func' at (1) is of type 'z', which has not been
defined
module x
type t
integer :: i
end type t
end module x
type(z) function func()
use x, only: z=>t
func%i = 5
end function func
This program is accepted by NAG f95, g95, ifort, openf95 and sunf95.

* decl.c : Declare gfc_function_kind_locs and
gfc_function_type_locus.
(gfc_match_kind_spec): Add second argument kind_expr_only.
Store locus before trying to match the expression. If the
current state corresponds to a function declaration and there
is no match to the expression, read to the parenthesis, return
kind = -1, dump the expression and return.
(gfc_match_type_spec): Renamed from match_type_spec and all
references changed. If an interface or an external function,
store the locus, set kind = -1 and return. Otherwise, if kind
is already = -1, use gfc_find_symbol to try to find a use
associated or imported type.
match.h : Prototype for gfc_match_type_spec.
* parse.c (match_deferred_characteristics): New function.
(parse_spec): If in a function, statement is USE or IMPORT
or DERIVED_DECL and the function kind=-1, call
match_deferred_characteristics. If kind=-1 at the end of the
specification expressions, this is an error.
* parse.h : Declare external gfc_function_kind_locs and
gfc_function_type_locus.
