	PR fortran/37425
	* gfortran.h (struct gfc_namespace): New fields tb_uop_root and tb_op.
	(gfc_find_typebound_user_op): New routine.
	(gfc_find_typebound_intrinsic_op): Ditto.
	(gfc_check_operator_interface): Now public routine.
	* decl.c (gfc_match_generic): Match OPERATOR(X) or ASSIGNMENT(=).
	* interface.c (check_operator_interface): Made public, renamed to
	`gfc_check_operator_interface' accordingly and hand in the interface
	as gfc_symbol rather than gfc_interface so it is useful for type-bound
	operators, too.  Return boolean result.
	(gfc_check_interfaces): Adapt call to `check_operator_interface'.
	* symbol.c (gfc_get_namespace): Initialize new field `tb_op'.
	(gfc_free_namespace): Free `tb_uop_root'-based tree.
	(find_typebound_proc_uop): New helper function.
	(gfc_find_typebound_proc): Use it.
	(gfc_find_typebound_user_op): New method.
	(gfc_find_typebound_intrinsic_op): Ditto.
	* resolve.c (resolve_tb_generic_targets): New helper function.
	(resolve_typebound_generic): Use it.
	(resolve_typebound_intrinsic_op), (resolve_typebound_user_op): New.
	(resolve_typebound_procedures): Resolve operators, too.
	(check_uop_procedure): New, code from gfc_resolve_uops.
	(gfc_resolve_uops): Moved main code to new `check_uop_procedure'.
