        * class.c (class_depth): Return -1 if the class doesn't load
        properly.
        * expr.c (can_widen_reference_to): Check for errors during depth
        computation and return 0 accordingly.
        * jcf-parse.c (parse_source_file): Call java_fix_constructors to
        create default constructors and add an other error check.
        * parse.h (java_fix_constructors): Prototyped.
        * parse.y (java_pre_expand_clinit): Likewise.
        (build_super_invocation): Re-prototyped to feature one argument.
        (java_check_circular_reference): Directly use `current'.
        (java_fix_constructors): New function.
        (java_check_regular_methods): Don't create default constructors
        here, but abort if none were found.
        (java_complete_expand_methods): Pre-process <clinit> calling
        java_pre_expand_clinit.
        (java_pre_expand_clinit): New function.
        (fix_constructors): build_super_invocation invoked with the
        current method declaration as an argument.
        (build_super_invocation): Use the context of the processed method
        decl argument instead of current_class.
        * typeck.c (lookup_java_method): Take WFLs in method names into
        account.
