        * 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.
