	PR fortran/31229
	PR fortran/33334
	* 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.
