* parse.y (value_expr0): class and module statements should not be
warned for "void value expression". [ruby-talk:72989] * gc.c (add_final): should determine type by respond_to? * gc.c (define_final): ditto. * io.c (rb_io_ctl): should not depend on respond_to? * range.c (range_step): rb_check_string_type(). * process.c (proc_setgroups): new functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@3918 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
