	PR fortran/29975
	PR fortran/30068
	PR fortran/30096
	* interface.c (compare_type_rank_if): Reject invalid generic
	interfaces.
	(check_interface1): Give a warning for nonreferred to ambiguous
	interfaces.
	(check_sym_interfaces): Check whether an ambiguous interface is
	referred to.  Do not check host associated interfaces since these
	cannot be ambiguous with the local versions.
	(check_uop_interface, gfc_check_interfaces): Update call to
	check_interface1.
	* symbol.c (gfc_get_sym_tree, gfc_get_sym_tree): Allow adding
	unambiguous procedures to generic interfaces.
	* gfortran.h (symbol_attribute): Added use_only and
	ambiguous_interfaces.
	* module.c (load_need): Set the use_only flag, if needed.
	* resolve.c (resolve_fl_procedure): Warn for nonreferred
	interfaces.
	* expr.c (find_array_section): Fix initializer array contructor.
