jcf-parse.c (init_jcf_parse): Register current_file_list root.

        * jcf-parse.c (init_jcf_parse): Register current_file_list root.
        Move current_file_list out of yyparse and make it static.

        * expr.c: Declare quick_stack and tree_list_free_list as static
        (init_expr_processing): Register quick_stack and
        tree_list_free_list roots.
